Mod 3 Ch 43-45 24,26,17

1. A client in the emergency department is having a stroke and the provider has prescribed the tissue plasminogen activator (t-PA) alteplase (Activase). The client weighs 146 pounds. How much medication will this client receive? (Record your answer using a whole number.) _____ mg

ANS: 60 mg The dose of t-PA is 0.9 mg/kg with a maximum dose of 90 mg. The client weighs 66.4 kg. 0.9 mg ´ 66.4 = 59.76 mg, which rounds to 60 mg. REF: 939

17. A client who had a severe traumatic brain injury is being discharged home, where the spouse will be a full-time caregiver. What statement by the spouse would lead the nurse to provide further education on home care? a. "I know I can take care of all these needs by myself." b. "I need to seek counseling because I am very angry." c. "Hopefully things will improve gradually over time." d. "With respite care and support, I think I can do this."

ANS: A This caregiver has unrealistic expectations about being able to do everything without help. Acknowledging anger and seeking counseling show a realistic outlook and plans for accomplishing goals. Hoping for improvement over time is also realistic, especially with the inclusion of the word "hopefully." Realizing the importance of respite care and support also is a realistic outlook. REF: 957

8. A nurse plans care for a client with a halo fixator. Which interventions should the nurse include in this client's plan of care? (Select all that apply.) a. Tape a halo wrench to the client's vest. b. Assess the pin sites for signs of infection. c. Loosen the pins when sleeping. d. Decrease the client's oral fluid intake. e. Assess the chest and back for skin breakdown.

ANS: A, B, E A special halo wrench should be taped to the client's vest in case of a cardiopulmonary emergency. The nurse should assess the pin sites for signs of infection or loose pins and for complications from the halo. The nurse should also increase fluids and fiber to decrease bowel straining and assess the client's chest and back for skin breakdown from the halo vest. REF: 897

4. A nurse has applied to work at a hospital that has National Stroke Center designation. The nurse realizes the hospital adheres to eight Core Measures for ischemic stroke care. What do these Core Measures include? (Select all that apply.) a. Discharging the client on a statin medication b. Providing the client with comprehensive therapies c. Meeting goals for nutrition within 1 week d. Providing and charting stroke education e. Preventing venous thromboembolism

ANS: A, D, E Core Measures established by The Joint Commission include discharging stroke clients on statins, providing and recording stroke education, and taking measures to prevent venous thromboembolism. The client must be assessed for therapies but may go elsewhere for them. Nutrition goals are not part of the Core Measures. REF: 945

4. A nurse cares for a client with a lower motor neuron injury who is experiencing a flaccid bowel elimination pattern. Which actions should the nurse take to assist in relieving this client's constipation? (Select all that apply.) a. Pour warm water over the perineum. b. Provide a diet high in fluids and fiber. c. Administer daily tap water enemas. d. Implement a consistent daily time for elimination. e. Massage the abdomen from left to right. f. Perform manual disimpaction.

ANS: B, D, F For the client with a lower motor neuron injury, the resulting flaccid bowel may require a bowel program for the client that includes stool softeners, increased fluid intake, a high-fiber diet, and a consistent elimination time. If the client becomes impacted, the nurse would need to perform manual disimpaction. Pouring warm water over the perineum, administering daily enemas, and massaging the abdomen would not assist this client. REF: 900

21. A nurse cares for a client with amyotrophic lateral sclerosis (ALS). The client states, "I do not want to be placed on a mechanical ventilator." How should the nurse respond? a. "You should discuss this with your family and health care provider." b. "Why are you afraid of being placed on a breathing machine?" c. "Using the incentive spirometer each hour will delay the need for a ventilator." d. "What would you like to be done if you begin to have difficulty breathing?"

ANS: D ALS is an adult-onset upper and lower motor neuron disease characterized by progressive weakness, muscle wasting, and spasticity, eventually leading to paralysis. Once muscles of breathing are involved, the client must indicate in the advance directive what is to be done when breathing is no longer possible without intervention. The other statements do not address the client's needs. REF: 911

14. A nurse cares for a client who presents with an acute exacerbation of multiple sclerosis (MS). Which prescribed medication should the nurse prepare to administer? a. Baclofen (Lioresal) b. Interferon beta-1b (Betaseron) c. Dantrolene sodium (Dantrium) d. Methylprednisolone (Medrol)

ANS: D Methylprednisolone is the drug of choice for acute exacerbations of the disease. The other drugs are not used to treat acute exacerbations of MS. Interferon beta-1b is used to treat and control MS, decrease specific symptoms, and slow the progression of the disease. Baclofen and dantrolene sodium are prescribed to lessen muscle spasticity associated with MS. REF: 908

6. A client with myasthenia gravis has the priority client problem of inadequate nutrition. What assessment finding indicates that the priority goal for this client problem has been met? a. Ability to chew and swallow without aspiration b. Eating 75% of meals and between-meal snacks c. Intake greater than output 3 days in a row d. Weight gain of 3 pounds in 1 month

ANS: D Weight gain is the best indicator that the client is receiving enough nutrition. Being able to chew and swallow is important for eating, but adequate nutrition can be accomplished through enteral means if needed. Swallowing without difficulty indicates an intact airway. Since the question does not indicate what the client's meals and snacks consist of, eating 75% may or may not be adequate. Intake and output refers to fluid balance. REF: 921

2. A client in the emergency department is having a stroke. The client weighs 225 pounds. After the initial bolus of t-Pa, at what rate should the nurse set the IV pump? (Record your answer using a decimal rounded to the nearest tenth.) ____ mL/hr

ANS: 1.4 mL/hr The client weighs 102 kg. The dose of t-PA is 0.9 mg/kg with a maximum of 90 mg, so the client's dose is 90 mg. 10% of the dose is given as a bolus IV over the first minute (9 mg). That leaves 81 mg to run in over 59 minutes. , which rounds to 1.4 mL/hr. REF: 939

12. A nurse is caring for four clients in the neurologic intensive care unit. After receiving the hand-off report, which client should the nurse see first? a. Client with a Glasgow Coma Scale score that was 10 and is now is 8 b. Client with a Glasgow Coma Scale score that was 9 and is now is 12 c. Client with a moderate brain injury who is amnesic for the event d. Client who is requesting pain medication for a headache

ANS: A A 2-point decrease in the Glasgow Coma Scale score is clinically significant and the nurse needs to see this client first. An improvement in the score is a good sign. Amnesia is an expected finding with brain injuries, so this client is lower priority. The client requesting pain medication should be seen after the one with the declining Glasgow Coma Scale score. REF: 952

2. A client had an embolic stroke and is having an echocardiogram. When the client asks why the provider ordered "a test on my heart," how should the nurse respond? a. "Most of these types of blood clots come from the heart." b. "Some of the blood clots may have gone to your heart too." c. "We need to see if your heart is strong enough for therapy." d. "Your heart may have been damaged in the stroke too."

ANS: A An embolic stroke is caused when blood clots travel from one area of the body to the brain. The most common source of the clots is the heart. The other statements are inaccurate. REF: 931

1. A nurse promotes the prevention of lower back pain by teaching clients at a community center. Which instruction should the nurse include in this education? a. "Participate in an exercise program to strengthen muscles." b. "Purchase a mattress that allows you to adjust the firmness." c. "Wear flat instead of high-heeled shoes to work each day." d. "Keep your weight within 20% of your ideal body weight."

ANS: A Exercise can strengthen back muscles, reducing the incidence of low back pain. The other options will not prevent low back pain. REF: 886

24. A nurse is providing community screening for risk factors associated with stroke. Which client would the nurse identify as being at highest risk for a stroke? a. A 27-year-old heavy cocaine user b. A 30-year-old who drinks a beer a day c. A 40-year-old who uses seasonal antihistamines d. A 65-year-old who is active and on no medications

ANS: A Heavy drug use, particularly cocaine, is a risk factor for stroke. Heavy alcohol use is also a risk factor, but one beer a day is not considered heavy drinking. Antihistamines may contain phenylpropanolamine, which also increases the risk for stroke, but this client uses them seasonally and there is no information that they are abused or used heavily. The 65-year-old has only age as a risk factor. REF: 933

10. A nurse is seeing many clients in the neurosurgical clinic. With which clients should the nurse plan to do more teaching? (Select all that apply.) a. Client with an aneurysm coil placed 2 months ago who is taking ibuprofen (Motrin) for sinus headaches b. Client with an aneurysm clip who states that his family is happy there is no chance of recurrence c. Client who had a coil procedure who says that there will be no problem following up for 1 year d. Client who underwent a flow diversion procedure 3 months ago who is taking docusate sodium (Colace) for constipation e. Client who underwent surgical aneurysm ligation 3 months ago who is planning to take a Caribbean cruise

ANS: A, B After a coil procedure, up to 20% of clients experience re-bleeding in the first year. The client with this coil should not be taking drugs that interfere with clotting. An aneurysm clip can move up to 5 years after placement, so this client and family need to be watchful for changing neurologic status. The other statements show good understanding. REF: 940

5. The nurse caring for a client with Guillain-Barré syndrome has identified the priority client problem of decreased mobility for the client. What actions by the nurse are best? (Select all that apply.) a. Ask occupational therapy to help the client with activities of daily living. b. Consult with the provider about a physical therapy consult. c. Provide the client with information on support groups. d. Refer the client to a medical social worker or chaplain. e. Work with speech therapy to design a high-protein diet.

ANS: A, B, E Improving mobility and strength involves the collaborative assistance of occupational therapy, physical therapy, and speech therapy. While support groups, social work, or chaplain referrals may be needed, they do not help with mobility. REF: 916

1. A nursing student studying the neurologic system learns which information? (Select all that apply.) a. An aneurysm is a ballooning in a weakened part of an arterial wall. b. An arteriovenous malformation is the usual cause of strokes. c. Intracerebral hemorrhage is bleeding directly into the brain. d. Reduced perfusion from vasospasm often makes stroke worse. e. Subarachnoid hemorrhage is caused by high blood pressure.

ANS: A, C, D An aneurysm is a ballooning of the weakened part of an arterial wall. Intracerebral hemorrhage is bleeding directly into the brain. Vasospasm often makes the damage from the initial stroke worse because it causes decreased perfusion. An arteriovenous malformation (AVM) is unusual. Subarachnoid hemorrhage is usually caused by a ruptured aneurysm or AVM. REF: 932

5. A nursing student studying traumatic brain injuries (TBIs) should recognize which facts about these disorders? (Select all that apply.) a. A client with a moderate trauma may need hospitalization. b. A Glasgow Coma Scale score of 10 indicates a mild brain injury. c. Only open head injuries can cause a severe TBI. d. A client with a Glasgow Coma Scale score of 3 has severe TBI. e. The terms "mild TBI" and "concussion" have similar meanings.

ANS: A, D, E "Mild TBI" is a term used synonymously with the term "concussion." A moderate TBI has a Glasgow Coma Scale (GCS) score of 9 to 12, and these clients may need to be hospitalized. Both open and closed head injuries can cause a severe TBI, which is characterized by a GCS score of 3 to 8. REF: 947

4. An older adult client is hospitalized with Guillain-Barré syndrome. The client is given amitriptyline (Elavil). After receiving the hand-off report, what actions by the nurse are most important? (Select all that apply.) a. Administering the medication as ordered b. Advising the client to have help getting up c. Consulting the provider about the drug d. Cutting the dose of the drug in half e. Placing the client on safety precautions

ANS: B, C, E Amitriptyline is a tricyclic antidepressant and is considered inappropriate for use in older clients due to concerns of anticholinergic effects, confusion, and safety risks. The nurse should tell the client to have help getting up, place the client on safety precautions, and consult the provider. Since this drug is not appropriate for older clients, cutting the dose in half is not warranted. REF: 916

18. A nurse cares for several clients on a neurologic unit. Which prescription for a client should direct the nurse to ensure that an informed consent has been obtained before the test or procedure? a. Sensation measurement via the pinprick method b. Computed tomography of the cranial vault c. Lumbar puncture for cerebrospinal fluid sampling d. Venipuncture for autoantibody analysis

ANS: C A lumbar puncture is an invasive procedure with many potentially serious complications. The other assessments or tests are considered noninvasive and do not require an informed consent. REF: 888

3. A client with Guillain-Barré syndrome is admitted to the hospital. The nurse plans caregiving priority to interventions that address which priority client problem? a. Anxiety b. Low fluid volume c. Inadequate airway d. Potential for skin breakdown

ANS: C Airway takes priority. Anxiety is probably present, but a physical diagnosis takes priority over a psychosocial one. The client has no reason to have low fluid volume unless he or she has been unable to drink for some time. If present, airway problems take priority over a circulation problem. An actual problem takes precedence over a risk for a problem. REF: 914

3. After teaching a male client with a spinal cord injury at the T4 level, the nurse assesses the client's understanding. Which client statements indicate a correct understanding of the teaching related to sexual effects of this injury? (Select all that apply.) a. "I will explore other ways besides intercourse to please my partner." b. "I will not be able to have an erection because of my injury." c. "Ejaculation may not be as predictable as before." d. "I may urinate with ejaculation but this will not cause infection." e. "I should be able to have an erection with stimulation."

ANS: C, D, E Men with injuries above T6 often are able to have erections by stimulating reflex activity. For example, stroking the penis will cause an erection. Ejaculation is less predictable and may be mixed with urine. However, urine is sterile, so the client's partner will not get an infection. REF: 901

6. A nurse assesses a client with paraplegia from a spinal cord injury and notes reddened areas over the client's hips and sacrum. Which actions should the nurse take? (Select all that apply.) a. Apply a barrier cream to protect the skin from excoriation. b. Perform range-of-motion (ROM) exercises for the hip joint. c. Re-position the client off of the reddened areas. d. Get the client out of bed and into a chair once a day. e. Obtain a low-air-loss mattress to minimize pressure.

ANS: C, E Appropriate interventions to relieve pressure on these areas include frequent re-positioning and a low-air-loss mattress. Reddened areas should not be rubbed because this action could cause more extensive damage to the already fragile capillary system. Barrier cream will not protect the skin from pressure wounds. ROM exercises are used to prevent contractures. Sitting the client in a chair once a day will decrease the client's risk of respiratory complications but will not decrease pressure on the client's hips and sacrum. REF: 898

3. A nurse assesses a client who is recovering from a diskectomy 6 hours ago. Which assessment finding should the nurse address first? a. Sleepy but arouses to voice b. Dry and cracked oral mucosa c. Pain present in lower back d. Bladder palpated above pubis

ANS: D A distended bladder may indicate damage to the sacral spinal nerves. The other findings require the nurse to provide care but are not the priority or a complication of the procedure. REF: 889

2. The nurse learns that the pathophysiology of Guillain-Barré syndrome includes segmental demyelination. The nurse should understand that this causes what? a. Delayed afferent nerve impulses b. Paralysis of affected muscles c. Paresthesia in upper extremities d. Slowed nerve impulse transmission

ANS: D Demyelination leads to slowed nerve impulse transmission. The other options are not correct. REF: 914

8. An emergency room nurse initiates care for a client with a cervical spinal cord injury who arrives via emergency medical services. Which action should the nurse take first? a. Assess level of consciousness. b. Obtain vital signs. c. Administer oxygen therapy. d. Evaluate respiratory status.

ANS: D The first priority for a client with a spinal cord injury is assessment of respiratory status and airway patency. Clients with cervical spine injuries are particularly prone to respiratory compromise and may even require intubation. The other assessments should be performed after airway and breathing are assessed. REF: 894

2. A client has been diagnosed with Bell's palsy. About what drugs should the nurse anticipate possibly teaching the client? (Select all that apply.) a. Acyclovir (Zovirax) b. Carbamazepine (Tegretol) c. Famciclovir (Famvir) d. Prednisone (Deltasone) e. Valacyclovir (Valtrex)

ANS: A, C, D, E Possible pharmacologic treatment for Bell's palsy includes acyclovir, famciclovir, prednisone, and valacyclovir. Carbamazepine is an anticonvulsant and mood-stabilizing drug and is not used for Bell's palsy. REF: 927

28. After a stroke, a client has ataxia. What intervention is most appropriate to include on the client's plan of care? a. Ambulate only with a gait belt. b. Encourage double swallowing. c. Monitor lung sounds after eating. d. Perform post-void residuals.

ANS: A Ataxia is a gait disturbance. For the client's safety, he or she should have assistance and use a gait belt when ambulating. Ataxia is not related to swallowing, aspiration, or voiding. REF: 934

21. A client has a brain abscess and is receiving phenytoin (Dilantin). The spouse questions the use of the drug, saying the client does not have a seizure disorder. What response by the nurse is best? a. "Increased pressure from the abscess can cause seizures." b. "Preventing febrile seizures with an abscess is important." c. "Seizures always occur in clients with brain abscesses." d. "This drug is used to sedate the client with an abscess."

ANS: A Brain abscesses can lead to seizures as a complication. The nurse should explain this to the spouse. Phenytoin is not used to prevent febrile seizures. Seizures are possible but do not always occur in clients with brain abscesses. This drug is not used for sedation. REF: 955

5. A client is taking long-term corticosteroids for myasthenia gravis. What teaching is most important? a. Avoid large crowds and people who are ill. b. Check blood sugars four times a day. c. Use two forms of contraception. d. Wear properly fitting socks and shoes.

ANS: A Corticosteroids reduce immune function, so clients taking these medications must avoid being exposed to illness. Long-term use can lead to secondary diabetes, but the client would not need to start checking blood glucose unless diabetes had been detected. Corticosteroids do not affect the effectiveness of contraception. Wearing well-fitting shoes would be important to avoid injury, but not just because the client takes corticosteroids. REF: 920

12. An older client is hospitalized with Guillain-Barré syndrome. A family member tells the nurse the client is restless and seems confused. What action by the nurse is best? a. Assess the client's oxygen saturation. b. Check the medication list for interactions. c. Place the client on a bed alarm. d. Put the client on safety precautions.

ANS: A In the older adult, an early sign of hypoxia is often confusion and restlessness. The nurse should first assess the client's oxygen saturation. The other actions are appropriate, but only after this assessment occurs. REF: 916

13. A client with myasthenia gravis (MG) asks the nurse to explain the disease. What response by the nurse is best? a. "MG is an autoimmune problem in which nerves do not cause muscles to contract." b. "MG is an inherited destruction of peripheral nerve endings and junctions." c. "MG consists of trauma-induced paralysis of specific cranial nerves." d. "MG is a viral infection of the dorsal root of sensory nerve fibers."

ANS: A MG is an autoimmune disorder in which nerve fibers are damaged and their impulses do not lead to muscle contraction. MG is not an inherited or viral disorder and does not paralyze specific cranial nerves. REF: 917

7. A client had a nerve laceration repair to the forearm and is being discharged in a cast. What statement by the client indicates a poor understanding of discharge instructions relating to cast care? a. "I can scratch with a coat hanger." b. "I should feel my fingers for warmth." c. "I will keep the cast clean and dry." d. "I will return to have the cast removed."

ANS: A Nothing should be placed under the cast to use for scratching. The other statements show good indication that the client has understood the discharge instructions. REF: 925

12. After teaching a client with a spinal cord injury, the nurse assesses the client's understanding. Which client statement indicates a correct understanding of how to prevent respiratory problems at home? a. "I'll use my incentive spirometer every 2 hours while I'm awake." b. "I'll drink thinned fluids to prevent choking." c. "I'll take cough medicine to prevent excessive coughing." d. "I'll position myself on my right side so I don't aspirate."

ANS: A Often, the person with a spinal cord injury will have weak intercostal muscles and is at higher risk for developing atelectasis and stasis pneumonia. Using an incentive spirometer every 2 hours helps the client expand the lungs more fully and prevents atelectasis. Clients should drink fluids that they can tolerate; usually thick fluids are easier to tolerate. The client should be encouraged to cough and clear secretions. Clients should be placed in high-Fowler's position to prevent aspiration. REF: 896

13. A client is in the clinic for a follow-up visit after a moderate traumatic brain injury. The client's spouse is very frustrated, stating that the client's personality has changed and the situation is intolerable. What action by the nurse is best? a. Explain that personality changes are common following brain injuries. b. Ask the client why he or she is acting out and behaving differently. c. Refer the client and spouse to a head injury support group. d. Tell the spouse this is expected and he or she will have to learn to cope.

ANS: A Personality and behavior often change permanently after head injury. The nurse should explain this to the spouse. Asking the client about his or her behavior isn't useful because the client probably cannot help it. A referral might be a good idea, but the nurse needs to do something in addition to just referring the couple. Telling the spouse to learn to cope belittles the spouse's concerns and feelings. REF: 953

6. A nurse assesses a client who is recovering from anterior cervical diskectomy and fusion. Which complication should alert the nurse to urgently communicate with the health care provider? a. Auscultated stridor b. Weak pedal pulses c. Difficulty swallowing d. Inability to shrug shoulders

ANS: A Postoperative swelling can narrow the trachea, cause a partial airway obstruction, and manifest as stridor. The client may also have trouble swallowing, but maintaining an airway takes priority. Weak pedal pulses and an inability to shrug the shoulders are not complications of this surgery. REF: 896

16. A client with a traumatic brain injury is agitated and fighting the ventilator. What drug should the nurse prepare to administer? a. Carbamazepine (Tegretol) b. Dexmedetomidine (Precedex) c. Diazepam (Valium) d. Mannitol (Osmitrol)

ANS: B Dexmedetomidine is often used to manage agitation in the client with traumatic brain injury. Carbamazepine is an antiseizure drug. Diazepam is a benzodiazepine. Mannitol is an osmotic diuretic. REF: 955

20. A nurse assesses a client with the National Institutes of Health (NIH) Stroke Scale and determines the client's score to be 36. How should the nurse plan care for this client? a. The client will need near-total care. b. The client will need cuing only. c. The client will need safety precautions. d. The client will be discharged home.

ANS: A This client has severe neurologic deficits and will need near-total care. Safety precautions are important but do not give a full picture of the client's dependence. The client will need more than cuing to complete tasks. A home discharge may be possible, but this does not help the nurse plan care for a very dependent client. REF: 935

23. A client has a subarachnoid bolt. What action by the nurse is most important? a. Balancing and recalibrating the device b. Documenting intracranial pressure readings c. Handling the fiberoptic cable with care to avoid breakage d. Monitoring the client's phlebostatic axis

ANS: A This device needs frequent balancing and recalibration in order to read correctly. Documenting readings is important, but it is more important to ensure the device's accuracy. The fiberoptic transducer-tipped catheter has a cable that must be handled carefully to avoid breaking it, but ensuring the device's accuracy is most important. The phlebostatic axis is not related to neurologic monitoring. REF: 956

9. A client has a small-bore feeding tube (Dobhoff tube) inserted for continuous enteral feedings while recovering from a traumatic brain injury. What actions should the nurse include in the client's care? (Select all that apply.) a. Assess tube placement per agency policy. b. Keep the head of the bed elevated at least 30 degrees. c. Listen to lung sounds at least every 4 hours. d. Run continuous feedings on a feeding pump. e. Use blue dye to determine proper placement.

ANS: A, B, C, D All of these options are important for client safety when continuous enteral feedings are in use. Blue dye is not used because it can cause lung injury if aspirated. REF: 955

2. After teaching a client with a spinal cord tumor, the nurse assesses the client's understanding. Which statements by the client indicate a correct understanding of the teaching? (Select all that apply.) a. "Even though turning hurts, I will remind you to turn me every 2 hours." b. "Radiation therapy can shrink the tumor but also can cause more problems." c. "Surgery will be scheduled to remove the tumor and reverse my symptoms." d. "I put my affairs in order because this type of cancer is almost always fatal." e. "My family is moving my bedroom downstairs for when I am discharged home."

ANS: A, B, E Although surgery may relieve symptoms by reducing pressure on the spine and debulking the tumor, some motor and sensory deficits may remain. Spinal tumors usually cause disability but are not usually fatal. Radiation therapy is often used to shrink spinal tumors but can cause progressive spinal cord degeneration and neurologic deficits. The client should be turned every 2 hours to prevent skin breakdown and arrangements should be made at home so that the client can complete activities of daily living without needing to go up and down stairs. REF: 903

6. A nurse cares for older clients who have traumatic brain injury. What should the nurse understand about this population? (Select all that apply.) a. Admission can overwhelm the coping mechanisms for older clients. b. Alcohol is typically involved in most traumatic brain injuries for this age group. c. These clients are more susceptible to systemic and wound infections. d. Other medical conditions can complicate treatment for these clients. e. Very few traumatic brain injuries occur in this age group.

ANS: A, C, D Older clients often tolerate stress poorly, which includes being admitted to a hospital that is unfamiliar and noisy. Because of decreased protective mechanisms, they are more susceptible to both local and systemic infections. Other medical conditions can complicate their treatment and recovery. Alcohol is typically not related to traumatic brain injury in this population; such injury is most often from falls and motor vehicle crashes. The 65- to 76-year-old age group has the second highest rate of brain injuries compared to other age groups. REF: 951

2. The nurse working in the emergency department assesses a client who has symptoms of stroke. For what modifiable risk factors should the nurse assess? (Select all that apply.) a. Alcohol intake b. Diabetes c. High-fat diet d. Obesity e. Smoking

ANS: A, C, D, E Alcohol intake, a high-fat diet, obesity, and smoking are all modifiable risk factors for stroke. Diabetes is not modifiable but is a risk factor that can be controlled with medical intervention. REF: 933

1. A nurse assesses a client who recently experienced a traumatic spinal cord injury. Which assessment data should the nurse obtain to assess the client's coping strategies? (Select all that apply.) a. Spiritual beliefs b. Level of pain c. Family support d. Level of independence e. Annual income f. Previous coping strategies

ANS: A, C, D, F Information about the client's preinjury psychosocial status, usual methods of coping with illness, difficult situations, and disappointments should be obtained. Determine the client's level of independence or dependence and his or her comfort level in discussing feelings and emotions with family members or close friends. Clients who are emotionally secure and have a positive self-image, a supportive family, and financial and job security often adapt to their injury. Information about the client's spiritual and religious beliefs or cultural background also assists the nurse in developing the plan of care. The other options do not supply as much information about coping. REF: 894

5. A client is being prepared for a mechanical embolectomy. What action by the nurse takes priority? a. Assess for contraindications to fibrinolytics. b. Ensure that informed consent is on the chart. c. Perform a full neurologic assessment. d. Review the client's medication lists.

ANS: B For this invasive procedure, the client needs to give informed consent. The nurse ensures that this is on the chart prior to the procedure beginning. Fibrinolytics are not used. A neurologic assessment and medication review are important, but the consent is the priority. REF: 938

22. A client has an intraventricular catheter. What action by the nurse takes priority? a. Document intracranial pressure readings. b. Perform hand hygiene before client care. c. Measure intracranial pressure per hospital policy. d. Teach the client and family about the device.

ANS: B All of the actions are appropriate for this client. However, performing hand hygiene takes priority because it prevents infection, which is a possibly devastating complication. REF: 961

22. A nurse assesses the health history of a client who is prescribed ziconotide (Prialt) for chronic back pain. Which assessment question should the nurse ask? a. "Are you taking a nonsteroidal anti-inflammatory drug?" b. "Do you have a mental health disorder?" c. "Are you able to swallow medications?" d. "Do you smoke cigarettes or any illegal drugs?"

ANS: B Clients who have a mental health or behavioral health problem should not take ziconotide. The other questions do not identify a contraindication for this medication. REF: 891

5. A nurse teaches a client who is recovering from a spinal fusion. Which statement should the nurse include in this client's postoperative instructions? a. "Only lift items that are 10 pounds or less." b. "Wear your brace whenever you are out of bed." c. "You must remain in bed for 3 weeks after surgery." d. "You are prescribed medications to prevent rejection."

ANS: B Clients who undergo spinal fusion are fitted with a brace that they must wear throughout the healing process (usually 3 to 6 months) whenever they are out of bed. The client should not lift anything. The client does not need to remain in bed. Medications for rejection prevention are not necessary for this procedure. REF: 888

15. A nurse is caring for four clients who might be brain dead. Which client would best meet the criteria to allow assessment of brain death? a. Client with a core temperature of 95° F (35° C) for 2 days b. Client in a coma for 2 weeks from a motor vehicle crash c. Client who is found unresponsive in a remote area of a field by a hunter d. Client with a systolic blood pressure of 92 mm Hg since admission

ANS: B In order to determine brain death, clients must meet four criteria: 1) coma from a known cause, 2) normal or near-normal core temperature, 3) normal systolic blood pressure, and 4) at least one neurologic examination. The client who was in the car crash meets two of these criteria. The clients with the lower temperature and lower blood pressure have only one of these criteria. There is no data to support assessment of brain death in the client found by the hunter. REF: 954

9. An emergency department nurse cares for a client who experienced a spinal cord injury 1 hour ago. Which prescribed medication should the nurse prepare to administer? a. Intrathecal baclofen (Lioresal) b. Methylprednisolone (Medrol) c. Atropine sulfate d. Epinephrine (Adrenalin)

ANS: B Methylprednisolone (Medrol) should be given within 8 hours of the injury. Clients who receive this therapy usually show improvement in motor and sensory function. The other medications are inappropriate for this client. REF: 908

16. A nurse is teaching a client with multiple sclerosis who is prescribed cyclophosphamide (Cytoxan) and methylprednisolone (Medrol). Which statement should the nurse include in this client's discharge teaching? a. "Take warm baths to promote muscle relaxation." b. "Avoid crowds and people with colds." c. "Relying on a walker will weaken your gait." d. "Take prescribed medications when symptoms occur."

ANS: B The client should be taught to avoid people with any type of upper respiratory illness because these medications are immunosuppressive. Warm baths will exacerbate the client's symptoms. Assistive devices may be required for safe ambulation. Medication should be taken at all times and should not be stopped. REF: 908

19. After a craniotomy, the nurse assesses the client and finds dry, sticky mucous membranes and restlessness. The client has IV fluids running at 75 mL/hr. What action by the nurse is best? a. Assess the client's magnesium level. b. Assess the client's sodium level. c. Increase the rate of the IV infusion. d. Provide oral care every hour.

ANS: B This client has manifestations of hypernatremia, which is a possible complication after craniotomy. The nurse should assess the client's serum sodium level. Magnesium level is not related. The nurse does not independently increase the rate of the IV infusion. Providing oral care is also a good option but does not take priority over assessing laboratory results. REF: 961

1. A client is in the emergency department reporting a brief episode during which he was dizzy, unable to speak, and felt like his legs were very heavy. Currently the client's neurologic examination is normal. About what drug should the nurse plan to teach the client? a. Alteplase (Activase) b. Clopidogrel (Plavix) c. Heparin sodium d. Mannitol (Osmitrol)

ANS: B This client's manifestations are consistent with a transient ischemic attack, and the client would be prescribed aspirin or clopidogrel on discharge. Alteplase is used for ischemic stroke. Heparin and mannitol are not used for this condition. REF: 930

3. A client with myasthenia gravis is malnourished. What actions to improve nutrition may the nurse delegate to the unlicensed assistive personnel (UAP)? (Select all that apply.) a. Assessing the client's gag reflex b. Cutting foods up into small bites c. Monitoring prealbumin levels d. Thickening liquids prior to drinking e. Weighing the client daily

ANS: B, D Cutting food up into smaller bites makes it easier for the client to chew and swallow. Thickened liquids help prevent aspiration. The UAP can weigh the client, but this does not help improve nutrition. The nurse assesses the gag reflex and monitors laboratory values. REF: 921

11. A nurse is dismissing a client from the emergency department who has a mild traumatic brain injury. What information obtained from the client represents a possible barrier to self-management? (Select all that apply.) a. Does not want to purchase a thermometer b. Is allergic to acetaminophen (Tylenol) c. Laughing, says "Strenuous? What's that?" d. Lives alone and is new in town with no friends e. Plans to have a beer and go to bed once home

ANS: B, D, E Clients should take acetaminophen for headache. An allergy to this drug may mean the client takes aspirin or ibuprofen (Motrin), which should be avoided. The client needs neurologic checks every 1 to 2 hours, and this client does not seem to have anyone available who can do that. Alcohol needs to be avoided for at least 24 hours. A thermometer is not needed. The client laughing at strenuous activity probably does not engage in any kind of strenuous activity, but the nurse should confirm this. REF: 957

3. A nurse is caring for a client after a stroke. What actions may the nurse delegate to the unlicensed assistive personnel (UAP)? (Select all that apply.) a. Assess neurologic status with the Glasgow Coma Scale. b. Check and document oxygen saturation every 1 to 2 hours. c. Cluster client care to allow periods of uninterrupted rest. d. Elevate the head of the bed to 45 degrees to prevent aspiration. e. Position the client supine with the head in a neutral midline position.

ANS: B, E The UAP can take and document vital signs, including oxygen saturation, and keep the client's head in a neutral, midline position with correct direction from the nurse. The nurse assesses the Glasgow Coma Scale score. The nursing staff should not cluster care because this can cause an increase in the intracranial pressure. The head of the bed should be minimally elevated, up to 30 degrees. REF: 938

4. The nurse is preparing a client for a Tensilon (edrophonium chloride) test. What action by the nurse is most important? a. Administering anxiolytics b. Having a ventilator nearby c. Obtaining atropine sulfate d. Sedating the client

ANS: C Atropine is the antidote to edrophonium chloride and should be readily available when a client is having a Tensilon test. The nurse would not want to give medications that might cause increased weakness or sedation. A ventilator is not necessary to have nearby, although emergency equipment should be available. REF: 919

1. A client is admitted with Guillain-Barré syndrome (GBS). What assessment takes priority? a. Bladder control b. Cognitive perception c. Respiratory system d. Sensory functions

ANS: C Clients with GBS have muscle weakness, possibly to the point of paralysis. If respiratory muscles are paralyzed, the client may need mechanical ventilation, so the respiratory system is the priority. The nurse will complete urinary, cognitive, and sensory assessments as part of a thorough evaluation. REF: 915

13. A nurse assesses a client with early-onset multiple sclerosis (MS). Which clinical manifestation should the nurse expect to find? a. Hyperresponsive reflexes b. Excessive somnolence c. Nystagmus d. Heat intolerance

ANS: C Early signs and symptoms of MS include changes in motor skills, vision, and sensation. Hyperresponsive reflexes, excessive somnolence, and heat intolerance are later manifestations of MS. REF: 905

15. A nurse assesses a client with multiple sclerosis after administering prescribed fingolimod (Gilenya). For which adverse effect should the nurse monitor? a. Peripheral edema b. Black tarry stools c. Bradycardia d. Nausea and vomiting

ANS: C Fingolimod (Gilenya) is an antineoplastic agent that can cause bradycardia, especially within the first 6 hours after administration. Peripheral edema, black and tarry stools, and nausea and vomiting are not adverse effects of fingolimod. REF: 908

2. A nurse plans care for a client with lower back pain from a work-related injury. Which intervention should the nurse include in this client's plan of care? a. Encourage the client to stretch the back by reaching toward the toes. b. Massage the affected area with ice twice a day. c. Apply a heating pad for 20 minutes at least four times daily. d. Advise the client to avoid warm baths or showers.

ANS: C Heat increases blood flow to the affected area and promotes healing of injured nerves. Stretching and ice will not promote healing, and there is no need to avoid warm baths or showers. REF: 887

8. A client experiences impaired swallowing after a stroke and has worked with speech-language pathology on eating. What nursing assessment best indicates that a priority goal for this problem has been met? a. Chooses preferred items from the menu b. Eats 75% to 100% of all meals and snacks c. Has clear lung sounds on auscultation d. Gains 2 pounds after 1 week

ANS: C Impaired swallowing can lead to aspiration, so the priority goal for this problem is no aspiration. Clear lung sounds is the best indicator that aspiration has not occurred. Choosing menu items is not related to this problem. Eating meals does not indicate the client is not still aspirating. A weight gain indicates improved nutrition but still does not show a lack of aspiration. REF: 942

3. The nurse assumes care of a patient who has myasthenia gravis and notes that a dose of neostigmine (Prostigmin) due 1 hour prior was not given. The nurse will anticipate the patient to exhibit which symptoms? a. Excessive salivation b. Muscle spasms c. Muscle weakness d. Respiratory paralysis

ANS: C Neostigmine must be given on time to prevent myasthenic crisis, which is characterized by generalized, severe muscle weakness. The other symptoms are characteristic of cholinergic crisis, caused by too much medication. REF: Page 327

4. A nurse assesses clients at a community center. Which client is at greatest risk for lower back pain? a. A 24-year-old female who is 25 weeks pregnant b. A 36-year-old male who uses ergonomic techniques c. A 45-year-old male with osteoarthritis d. A 53-year-old female who uses a walker

ANS: C Osteoarthritis causes changes to support structures, increasing the client's risk for low back pain. The other clients are not at high risk. REF: 886

11. A nurse is caring for a client with paraplegia who is scheduled to participate in a rehabilitation program. The client states, "I do not understand the need for rehabilitation; the paralysis will not go away and it will not get better." How should the nurse respond? a. "If you don't want to participate in the rehabilitation program, I'll let the provider know." b. "Rehabilitation programs have helped many clients with your injury. You should give it a chance." c. "The rehabilitation program will teach you how to maintain the functional ability you have and prevent further disability." d. "When new discoveries are made regarding paraplegia, people in rehabilitation programs will benefit first."

ANS: C Participation in rehabilitation programs has many purposes, including prevention of disability, maintenance of functional ability, and restoration of function. The other responses do not meet this client's needs. REF: 900

11. A client is receiving plasmapheresis. What action by the nurse best prevents infection in this client? a. Giving antibiotics prior to treatments b. Monitoring the client's vital signs c. Performing appropriate hand hygiene d. Placing the client in protective isolation

ANS: C Plasmapheresis is an invasive procedure, and the nurse uses good hand hygiene before and after client contact to prevent infection. Antibiotics are not necessary. Monitoring vital signs does not prevent infection but could alert the nurse to its possibility. The client does not need isolation. REF: 915

4. The nurse is caring for a patient who has myasthenia gravis (MG) and takes pyridostigmine bromide (Mestinon) 60 mg every 4 hours. The patient's last dose was 45 minutes prior. The nurse notes severe muscle weakness, excess salivation, fasciculations of facial muscles, and pupil constriction. The nurse will perform which action? a. Assess the patient for signs of ptosis. b. Notify the provider to discuss an order for intravenous immune globulin (IVIG). c. Obtain an order for atropine sulfate. d. Request an order for an extra dose of pyridostigmine.

ANS: C Severe muscle weakness, excess salivation, fasciculations of facial muscles, and pupil constriction are the major signs of cholinergic crisis, caused by excess pyridostigmine. The antidote is atropine, so the nurse should obtain an order to give this. Ptosis is sign of myasthenic crisis. IVIG is given to treat symptoms of MG and not used for cholinergic crisis. Giving extra pyridostigmine would increase the symptoms. REF: Page 327

9. A client has undergone a percutaneous stereotactic rhizotomy. What instruction by the nurse is most important on discharge from the ambulatory surgical center? a. "Avoid having teeth pulled for 1 year." b. "Brush your teeth with a soft toothbrush." c. "Do not use harsh chemicals on your face." d. "Inform your dentist of this procedure."

ANS: C The affected side is left without sensation after this procedure. The client should avoid putting harsh chemicals on the face because he or she will not feel burning or stinging on that side. This will help avoid injury. The other instructions are not necessary. REF: 927

7. A nurse assesses a client with a spinal cord injury at level T5. The client's blood pressure is 184/95 mm Hg, and the client presents with a flushed face and blurred vision. Which action should the nurse take first? a. Initiate oxygen via a nasal cannula. b. Place the client in a supine position. c. Palpate the bladder for distention. d. Administer a prescribed beta blocker.

ANS: C The client is manifesting symptoms of autonomic dysreflexia. Common causes include bladder distention, tight clothing, increased room temperature, and fecal impaction. If persistent, the client could experience neurologic injury. Precipitating conditions should be eliminated and the physician notified. The other actions would not be appropriate. REF: 899

20. A nurse cares for a client with a spinal cord injury. With which interdisciplinary team member should the nurse consult to assist the client with activities of daily living? a. Social worker b. Physical therapist c. Occupational therapist d. Case manager

ANS: C The occupational therapist instructs the client in the correct use of all adaptive equipment. In collaboration with the therapist, the nurse instructs family members or the caregiver about transfer skills, feeding, bathing, dressing, positioning, and skin care. The other team members are consulted to assist the client with unrelated issues. REF: 901

30. A client has a traumatic brain injury and a positive halo sign. The client is in the intensive care unit, sedated and on a ventilator, and is in critical but stable condition. What collaborative problem takes priority at this time? a. Inability to communicate b. Nutritional deficit c. Risk for acquiring an infection d. Risk for skin breakdown

ANS: C The positive halo sign indicates a leak of cerebrospinal fluid. This places the client at high risk of acquiring an infection. Communication and nutrition are not priorities compared with preventing a brain infection. The client has a definite risk for a skin breakdown, but it is not the immediate danger a brain infection would be. REF: 952

6. A client had an embolectomy for an arteriovenous malformation (AVM). The client is now reporting a severe headache and has vomited. What action by the nurse takes priority? a. Administer pain medication. b. Assess the client's vital signs. c. Notify the Rapid Response Team. d. Raise the head of the bed.

ANS: C This client may be experiencing a rebleed from the AVM. The most important action is to call the Rapid Response Team as this is an emergency. The nurse can assess vital signs while someone else notifies the Team, but getting immediate medical attention is the priority. Administering pain medication may not be warranted if the client must return to surgery. The optimal position for the client with an AVM has not been determined, but calling the Rapid Response Team takes priority over positioning. REF: 941

27. The nurse assesses a client's Glasgow Coma Scale (GCS) score and determines it to be 12 (a 4 in each category). What care should the nurse anticipate for this client? a. Can ambulate independently b. May have trouble swallowing c. Needs frequent re-orientation d. Will need near-total care

ANS: C This client will most likely be confused and need frequent re-orientation. The client may not be able to ambulate at all but should do so independently, not because of mental status. Swallowing is not assessed with the GCS. The client will not need near-total care. REF: 934

5. A nurse assesses a client who is recovering from a lumbar laminectomy. Which complications should alert the nurse to urgently communicate with the health care provider? (Select all that apply.) a. Surgical discomfort b. Redness and itching at the incision site c. Incisional bulging d. Clear drainage on the dressing e. Sudden and severe headache

ANS: C, D, E Bulging at the incision site or clear fluid on the dressing after a laminectomy strongly suggests a cerebrospinal fluid leak, which constitutes an emergency. Loss of cerebral spinal fluid may cause a sudden and severe headache, which is also an emergency situation. Pain, redness, and itching at the site are normal. REF: 889

14. The nurse is caring for four clients with traumatic brain injuries. Which client should the nurse assess first? a. Client with cerebral perfusion pressure of 72 mm Hg b. Client who has a Glasgow Coma Scale score of 12 c. Client with a PaCO2 of 36 mm Hg who is on a ventilator d. Client who has a temperature of 102° F (38.9° C)

ANS: D A fever is a poor prognostic indicator in clients with brain injuries. The nurse should see this client first. A Glasgow Coma Scale score of 12, a PaCO2 of 36, and cerebral perfusion pressure of 72 mm Hg are all desired outcomes. REF: 953

7. A patient exhibits ptosis of both eyes, and the provider orders edrophonium (Tensilon). The nurse notes immediate improvement of the ptosis. The nurse understands that this patient most likely has which disorder? a. Cerebral palsy b. Multiple sclerosis c. Muscle spasms d. Myasthenia gravis

ANS: D Improvement of symptoms after administration of edrophonium is diagnostic for myasthenia gravis. REF: Page 327

17. A nurse assesses a client with a neurologic disorder. Which assessment finding should the nurse identify as a late manifestation of amyotrophic lateral sclerosis (ALS)? a. Dysarthria b. Dysphagia c. Muscle weakness d. Impairment of respiratory muscles

ANS: D In ALS, progressive muscle atrophy occurs until a flaccid quadriplegia develops. Eventually, the respiratory muscles are involved, which leads to respiratory compromise. Dysarthria, dysphagia, and muscle weakness are early clinical manifestations of ALS. REF: 910

10. A nurse teaches a client with a lower motor neuron lesion who wants to achieve bladder control. Which statement should the nurse include in this client's teaching? a. "Stroke the inner aspect of your thigh to initiate voiding." b. "Use a clean technique for intermittent catheterization." c. "Implement digital anal stimulation when your bladder is full." d. "Tighten your abdominal muscles to stimulate urine flow."

ANS: D In clients with lower motor neuron problems such as spinal cord injury, performing a Valsalva maneuver or tightening the abdominal muscles are interventions that can initiate voiding. Stroking the inner aspect of the thigh may initiate voiding in a client who has an upper motor neuron problem. Intermittent catheterization and digital anal stimulation do not initiate voiding or bladder control. REF: 900

6. A patient experiences severe muscle weakness, and the provider orders edrophonium bromide (Tensilon). The patient begins to show improved muscle strength within a few minutes after administration of this drug. The nurse anticipates the provider will order which drug? a. Atropine sulfate b. Edrophonium bromide (Tensilon) c. Intravenous immune globulin (IVIG) d. Pyridostigmine HCl (Mestinon)

ANS: D In this case, edrophonium is used to diagnose myasthenia gravis. Since symptoms improved with the AChE inhibitor, the patient will benefit from a longer-acting AChE inhibitor such as pyridostigmine. Atropine is given for AChE inhibitor overdose. Edrophonium is very short-acting, so it will not be used for treatment. IVIG is used when other AChE inhibitors fail. REF: Page 329

8. A client in the family practice clinic has restless leg syndrome. Routine laboratory work reveals white blood cells 8000/mm3, magnesium 0.8 mEq/L, and sodium 138 mEq/L. What action by the nurse is best? a. Advise the client to restrict fluids. b. Assess the client for signs of infection. c. Have the client add table salt to food. d. Instruct the client on a magnesium supplement.

ANS: D Iron and magnesium deficiencies can sometimes exacerbate or increase symptoms of restless leg syndrome. The client's magnesium level is low, and the client should be advised to add a magnesium supplement. The other actions are not needed. REF: 925

19. A nurse prepares a client for prescribed magnetic resonance imaging (MRI). Which action should the nurse implement prior to the test? a. Implement nothing by mouth (NPO) status for 8 hours. b. Withhold all daily medications until after the examination. c. Administer morphine sulfate to prevent claustrophobia during the test. d. Place the client in a gown that has cloth ties instead of metal snaps.

ANS: D Metal objects are a hazard because of the magnetic field used in the MRI procedure. Morphine sulfate is not administered to prevent claustrophobia; lorazepam (Ativan) or diazepam (Valium) may be used instead. The client does not need to be NPO, and daily medications do not need to be withheld prior to MRI. REF: 895

1. The nurse is preparing to care for a patient who has myasthenia gravis. The nurse will be alert to symptoms affecting which body system in this patient? a. Cardiovascular system and postural muscles b. Central nervous system (CNS), memory, and cognition c. Gastrointestinal system (GI) and lower extremity muscles d. Respiratory system and facial muscles

ANS: D Myasthenia gravis causes fatigue and muscular weakness of the respiratory system, facial muscles, and extremities. It does not directly affect the cardiovascular system, CNS, or GI systems. REF: Page 326

2. A 40-year-old woman is diagnosed with myasthenia gravis, and her provider recommends removal of her thymus gland. She asks the nurse why this would be helpful. The nurse will explain that removal of the thymus gland may a. increase binding of acetylcholine (ACh) molecules to ACh receptors. b. increase the amount of ACh available at neuromuscular junction sites. c. reduce the number of acetylcholine receptor sites. d. reduce the autoimmune destruction of ACh receptor sites.

ANS: D Myasthenia gravis is an autoimmune disorder involving an antibody response against a subunit of the ACh receptor site. Since the thymus is involved in systemic immunity, it is thought that removing the thymus can inhibit this process. It does not increase binding of ACh molecules to receptors or increase the amount of ACh or reduce the number of ACh receptor sites. REF: Page 327

4. A client with a stroke is being evaluated for fibrinolytic therapy. What information from the client or family is most important for the nurse to obtain? a. Loss of bladder control b. Other medical conditions c. Progression of symptoms d. Time of symptom onset

ANS: D The time limit for initiating fibrinolytic therapy for a stroke is 3 to 4.5 hours, so the exact time of symptom onset is the most important information for this client. The other information is not as critical. REF: 938

18. A client in the intensive care unit is scheduled for a lumbar puncture (LP) today. On assessment, the nurse finds the client breathing irregularly with one pupil fixed and dilated. What action by the nurse is best? a. Ensure that informed consent is on the chart. b. Document these findings in the client's record. c. Give the prescribed preprocedure sedation. d. Notify the provider of the findings immediately.

ANS: D This client is exhibiting signs of increased intracranial pressure. The nurse should notify the provider immediately because performing the LP now could lead to herniation. Informed consent is needed for an LP, but this is not the priority. Documentation should be thorough, but again this is not the priority. The preprocedure sedation (or other preprocedure medications) should not be given as the LP will most likely be canceled. REF: 952

8. The charge nurse observes a nurse administer undiluted intravenous pyridostigmine bromide (Mestinon) at a rate of 0.8 mg/min. The charge nurse will stop the infusion and perform which action? a. Administer atropine sulfate to prevent cholinergic crisis. b. Monitor the patient closely for respiratory distress. c. Suggest that the nurse dilute the medication with colloidal fluids. d. Tell the nurse to slow the rate of infusion of the pyridostigmine.

ANS: D When given, IV pyridostigmine should be administered undiluted at a rate of 0.5 mg/min and should not be added to IV fluids. It is not necessary to administer atropine, since the patient is not symptomatic of cholinergic crisis. REF: Page 327

15. The nurse is caring for a patient who has multiple sclerosis. The patient is experiencing an acute attack. Which drug does the nurse anticipate the provider will order? a. Adrenocorticotropic hormone (ACTH) b. Cyclophosphamide (Cytoxan) c. Glatiramer acetate (Copaxone) d. Interferon-B (IFN-B)

ANS: A ACTH is given to treat an acute attack of MS. Glatiramer acetate and interferon are used for remission-exacerbation states. Cyclophosphamide is given for chronic, progressive symptoms. REF: Page 342

5. The nurse assumes care of a patient who has been receiving intermittent enteral feedings of 240 mL of Osmolite every 4 hours for the past 48 hours. The patient is in bed with the head of the bed elevated 60 degrees. The enteral tubing is intact, and the enteral pump is infusing at 360 mL per hour. The nurse notes 60 mL of solution left in the bag. The tubing is not labeled. What will the nurse do? a. Change and label the enteral tubing when this infusion is complete. b. Increase the infusion rate to 480 mL per hour to complete the infusion. c. Lower the head of the bed to 30 degrees. d. Stop the infusion and check for residual before resuming the infusion.

ANS: A All enteral equipment should be labeled and changed every 24 hours. Since the tubing is not labeled, the nurse should change and label it as soon as the current infusion is complete. The infusion is set so that 240 mL will infuse over 45 minutes, which is appropriate, so the rate does not need to be increased. The head of the bed should be at least 30 degrees, so there is no need to lower the head of the bed. The nurse should check for residual just prior to administering the next infusion, but it is not indicated at this point. REF: Page 246

7. An emergency room nurse assesses a client who was rescued from a home fire. The client suddenly develops a loud, brassy cough. Which action should the nurse take first? a. Apply oxygen and continuous pulse oximetry. b. Provide small quantities of ice chips and sips of water. c. Request a prescription for an antitussive medication. d. Ask the respiratory therapist to provide humidified air.

ANS: A Brassy cough and wheezing are some of the signs seen with inhalation injury. The first action by the nurse is to give the client oxygen. Clients with possible inhalation injury also need continuous pulse oximetry. Ice chips and humidified room air will not help the problem, and antitussives are not warranted. REF: 474

10. A client has trigeminal neuralgia and has begun skipping meals and not brushing his teeth, and his family believes he has become depressed. What action by the nurse is best? a. Ask the client to explain his feelings related to this disorder. b. Explain how dental hygiene is related to overall health. c. Refer the client to a medical social worker for assessment. d. Tell the client that he will become malnourished in time.

ANS: A Clients with trigeminal neuralgia are often afraid of causing pain, so they may limit eating, talking, dental hygiene, and socializing. The nurse first assesses the client for feelings related to having the disorder to determine if a psychosocial link is involved. The other options may be needed depending on the outcome of the initial assessment. REF: 927

9. A client with a stroke has damage to Broca's area. What intervention to promote communication is best for this client? a. Assess whether or not the client can write. b. Communicate using "yes-or-no" questions. c. Reinforce speech therapy exercises. d. Remind the client not to use neologisms.

ANS: A Damage to Broca's area often leads to expressive aphasia, wherein the client can understand what is said but cannot express thoughts verbally. In some instances the client can write. The nurse should assess to see if that ability is intact. "Yes-or-no" questions are not good for this type of client because he or she will often answer automatically but incorrectly. Reinforcing speech therapy exercises is good for all clients with communication difficulties. Neologisms are made-up "words" often used by clients with sensory aphasia. REF: 943

15. A nurse cares for a client with burn injuries. Which intervention should the nurse implement to appropriately reduce the client's pain? a. Administer the prescribed intravenous morphine sulfate. b. Apply ice to skin around the burn wound for 20 minutes. c. Administer prescribed intramuscular ketorolac (Toradol). d. Decrease tactile stimulation near the burn injuries.

ANS: A Drug therapy for pain management requires opioid and nonopioid analgesics. The IV route is used because of problems with absorption from the muscle and the stomach. For the client to avoid shivering, the room must be kept warm, and ice should not be used. Ice would decrease blood flow to the area. Tactile stimulation can be used for pain management. REF: 480

6. The nurse assesses a client who has a severe burn injury. Which statement indicates the client understands the psychosocial impact of a severe burn injury? a. "It is normal to feel some depression." b. "I will go back to work immediately." c. "I will not feel anger about my situation." d. "Once I get home, things will be normal."

ANS: A During the recovery period, and for some time after discharge from the hospital, clients with severe burn injuries are likely to have psychological problems that require intervention. Depression is one of these problems. Grief, loss, anxiety, anger, fear, and guilt are all normal feelings that can occur. Clients need to know that problems of physical care and psychological stresses may be overwhelming. REF: 489

14. A nurse administers topical gentamicin sulfate (Garamycin) to a client's burn injury. Which laboratory value should the nurse monitor while the client is prescribed this therapy? a. Creatinine b. Red blood cells c. Sodium d. Magnesium

ANS: A Gentamicin is nephrotoxic, and sufficient amounts can be absorbed through burn wounds to affect kidney function. Any client receiving gentamicin by any route should have kidney function monitored. Topical gentamicin will not affect the red blood cell count or the sodium or magnesium levels. REF: 486

21. A nurse delegates hydrotherapy to an unlicensed assistive personnel (UAP). Which statement should the nurse include when delegating this activity? a. "Keep the water temperature constant when showering the client." b. "Assess the wound beds during the hydrotherapy treatment." c. "Apply a topical enzyme agent after bathing the client." d. "Use sterile saline to irrigate and clean the client's wounds."

ANS: A Hydrotherapy is performed by showering the client on a special shower table. The UAP should keep the water temperature constant. This process allows the nurse to assess the wound beds, but a UAP cannot complete this act. Topical enzyme agents are not part of hydrotherapy. The irrigation does not need to be done with sterile saline. REF: 482

10. A patient has symptoms that are characteristic of multiple sclerosis (MS). Which diagnostic tests are likely to be ordered to aid in the diagnosis of this patient? a. Cerebrospinal fluid (CSF) immunoglobulin G and magnetic resonance imaging (MRI) b. CSF proteins and an angiography c. Serum albumin and a computed tomography (CT) scan d. Serum anti-acetylcholine antibodies and x-rays

ANS: A Laboratory tests that may suggest MS include CSF IgG and MRI. REF: Page 330

18. The nurse is caring for a patient who is being treated with total parenteral nutrition (TPN). The patient is experiencing chest pain, and the nurse observes shortness of breath and coughing along with cyanosis. The nurse understands that this patient is most likely experiencing which condition? a. Air embolism b. Pneumonia c. Pneumothorax d. Pulmonary edema

ANS: A Patients receiving TPN are at risk for air embolism and will report chest pain and be dyspneic with coughing and cyanosis. Patients with pneumonia will have cough and either adventitious breath sounds or diminished breath sounds. Patients with pneumothorax will have unilateral absent breath sounds and respiratory distress. Patients with pulmonary edema will have crackles and dyspnea. REF: Page 249

15. The nurse is caring for an adult with severe burns who weighs 60 kg. Prior to initiating total parenteral nutrition (TPN) therapy, the nurse reviews the orders. Which TPN order is correct for this patient? a. 3000 kcal, 120 g amino acids per day b. 2400 kcal, 50 g amino acids per day c. 1500 kcal, 100 g amino acids per day d. 3600 kcal, 150 g amino acids per day

ANS: A Patients should receive 30 to 60 kcal/kg/day and 1 to 2 g/kg/day of amino acids. For a 60-kg patient, the number of calories should be 1800 to 3600 kcal/day, and amino acids should be 60 to 120 g/day. REF: Page 248

25. A client has a shoulder injury and is scheduled for a magnetic resonance imaging (MRI). The nurse notes the presence of an aneurysm clip in the client's record. What action by the nurse is best? a. Ask the client how long ago the clip was placed. b. Have the client sign an informed consent form. c. Inform the provider about the aneurysm clip. d. Reschedule the client for computed tomography.

ANS: A Some older clips are metal, which would preclude the use of MRI. The nurse should determine how old the clip is and relay that information to the MRI staff. They can determine if the client is a suitable candidate for this examination. The client does not need to sign informed consent. The provider will most likely not know if the client can have an MRI with this clip. The nurse does not independently change the type of diagnostic testing the client receives. REF: 940

29. A client in the emergency department is having a stroke and needs a carotid artery angioplasty with stenting. The client's mental status is deteriorating. What action by the nurse is most appropriate? a. Attempt to find the family to sign a consent. b. Inform the provider that the procedure cannot occur. c. Nothing; no consent is needed in an emergency. d. Sign the consent form for the client.

ANS: A The nurse should attempt to find the family to give consent. If no family is present or can be found, under the principle of emergency consent, a life-saving procedure can be performed without formal consent. The nurse should not just sign the consent form. REF: 938

2. The nurse is preparing to administer an enteral feeding to a patient who receives 300 mL of Isocal over 30 minutes every 4 hours. The nurse checks the residual prior to initiating the feeding and notes a residual amount of 50 mL of formula. Which action will the nurse take next? a. Administer the feeding as ordered. b. Administer the feeding over 60 minutes. c. Hold the feeding and notify the patient's provider. d. Wait 1 hour and recheck the residual again.

ANS: A The nurse should determine gastric residual before each feeding when patients are receiving intermittent feedings. A residual greater than 50% of a previous feeding indicates delayed gastric emptying and warrants notifying the provider. This patient has a residual less than 50%, so the nurse may proceed with the next feeding. A residual of 50 mL is significant in patients receiving continuous enteral feedings. The nurse cannot change the rate of an enteral infusion without an order from the provider. REF: Page 247

11. A client has a traumatic brain injury. The nurse assesses the following: pulse change from 82 to 60 beats/min, pulse pressure increase from 26 to 40 mm Hg, and respiratory irregularities. What action by the nurse takes priority? a. Call the provider or Rapid Response Team. b. Increase the rate of the IV fluid administration. c. Notify respiratory therapy for a breathing treatment. d. Prepare to give IV pain medication.

ANS: A These manifestations indicate Cushing's syndrome, a potentially life-threatening increase in intracranial pressure (ICP), which is an emergency. Immediate medical attention is necessary, so the nurse notifies the provider or the Rapid Response Team. Increasing fluids would increase the ICP. The client does not need a breathing treatment or pain medication. REF: 952

10. The nurse is preparing to administer enteral nutrition to a patient who has had a stroke and who cannot swallow. A family member asks why the patient isn't receiving intravenous nutrition. What information will the nurse provide to the family member? a. Parenteral nutrition carries a higher risk of infection. b. Parenteral nutrition does not provide sufficient calories. c. Parenteral nutrition increases the risk of aspiration. d. Parenteral nutrition is hyperosmolar and increases the risk of dehydration.

ANS: A Total parenteral nutrition (TPN) carries a greater risk of sepsis than enteral nutrition. TPN can provide sufficient calories, and there is no increased risk of aspiration with TPN. TPN does not increase the risk of dehydration. REF: Page 244

1. A nurse cares for a client with burn injuries during the resuscitation phase. Which actions are priorities during this phase? (Select all that apply.) a. Administer analgesics. b. Prevent wound infections. c. Provide fluid replacement. d. Decrease core temperature. e. Initiate physical therapy.

ANS: A, B, C Nursing priorities during the resuscitation phase include securing the airway, supporting circulation and organ perfusion by fluid replacement, keeping the client comfortable with analgesics, preventing infection through careful wound care, maintaining body temperature, and providing emotional support. Physical therapy is inappropriate during the resuscitation phase but may be initiated after the client has been stabilized. REF: 473

7. A client has meningitis following brain surgery. What comfort measures may the nurse delegate to the unlicensed assistive personnel (UAP)? (Select all that apply.) a. Applying a cool washcloth to the head b. Assisting the client to a position of comfort c. Keeping voices soft and soothing d. Maintaining low lighting in the room e. Providing antipyretics for fever

ANS: A, B, C, D The client with meningitis often has high fever, pain, and some degree of confusion. Cool washcloths to the forehead are comforting and help with pain. Allowing the client to assume a position of comfort also helps manage pain. Keeping voices low and lights dimmed also helps convey caring in a nonthreatening manner. The nurse provides antipyretics for fever. REF: 962

1. A client with myasthenia gravis is prescribed pyridostigmine (Mestinon). What teaching should the nurse plan regarding this medication? (Select all that apply.) a. "Do not eat a full meal for 45 minutes after taking the drug." b. "Seek immediate care if you develop trouble swallowing." c. "Take this drug on an empty stomach for best absorption." d. "The dose may change frequently depending on symptoms." e. "Your urine may turn a reddish-orange color while on this drug."

ANS: A, B, D Pyridostigmine should be given with a small amount of food to prevent GI upset, but the client should wait to eat a full meal due to the potential for aspiration. If difficulty with swallowing occurs, the client should seek immediate attention. The dose can change on a day-to-day basis depending on the client's manifestations. Taking the drug on an empty stomach is not related although the client needs to eat within 45 to 60 minutes afterwards. The client's urine will not turn reddish-orange while on this drug. REF: 920

8. A nurse is working with many stroke clients. Which clients would the nurse consider referring to a mental health provider on discharge? (Select all that apply.) a. Client who exhibits extreme emotional lability b. Client with an initial National Institutes of Health (NIH) Stroke Scale score of 38 c. Client with mild forgetfulness and a slight limp d. Client who has a past hospitalization for a suicide attempt e. Client who is unable to walk or eat 3 weeks post-stroke

ANS: A, B, D, E Clients most at risk for post-stroke depression are those with a previous history of depression, severe stroke (NIH Stroke Scale score of 38 is severe), and post-stroke physical or cognitive impairment. The client with mild forgetfulness and a slight limp would be a low priority for this referral. REF: 935

2. A nurse cares for a client with burn injuries who is experiencing anxiety and pain. Which nonpharmacologic comfort measures should the nurse implement? (Select all that apply.) a. Music as a distraction b. Tactile stimulation c. Massage to injury sites d. Cold compresses e. Increasing client control

ANS: A, B, E Nonpharmacologic comfort measures for clients with burn injuries include music therapy, tactile stimulation, massaging unburned areas, warm compresses, and increasing client control. REF: 480

5. A nurse plans care for a client with burn injuries. Which interventions should the nurse implement to prevent infection in the client? (Select all that apply.) a. Ask all family members and visitors to perform hand hygiene before touching the client. b. Carefully monitor burn wounds when providing each dressing change. c. Clean equipment with alcohol between uses with each client on the unit. d. Allow family members to only bring the client plants from the hospital's gift shop. e. Use aseptic technique and wear gloves when performing wound care.

ANS: A, B, E To prevent infection in a client with burn injuries the nurse should ensure everyone performs hand hygiene, monitor wounds for signs of infection, and use aseptic technique, including wearing gloves when performing wound care. The client should have disposable equipment that is not shared with another client, and plants should not be allowed in the client's room. REF: 483

7. A nurse assesses a client who experienced a spinal cord injury at the T5 level 12 hours ago. Which manifestations should the nurse correlate with neurogenic shock? (Select all that apply.) a. Heart rate of 34 beats/min b. Blood pressure of 185/65 mm Hg c. Urine output less than 30 mL/hr d. Decreased level of consciousness e. Increased oxygen saturation

ANS: A, C, D Neurogenic shock with acute spinal cord injury manifests with decreased oxygen saturation, symptomatic bradycardia, decreased level of consciousness, decreased urine output, and hypotension. REF: 896

3. A nurse plans care for a client with burn injuries. Which interventions should the nurse include in this client's plan of care to ensure adequate nutrition? (Select all that apply.) a. Provide at least 5000 kcal/day. b. Start an oral diet on the first day. c. Administer a diet high in protein. d. Collaborate with a registered dietitian. e. Offer frequent high-calorie snacks.

ANS: A, C, D, E A client with a burn injury needs a high-calorie diet, including at least 5000 kcal/day and frequent high-calorie snacks. The nurse should collaborate with a registered dietitian to ensure the client receives a high-calorie and high-protein diet required for wound healing. Oral diet therapy should be delayed until GI motility resumes. REF: 485

1. A client with myasthenia gravis is experiencing a cholinergic crisis. Which symptoms are associated with this condition? (Select all that apply.) a. Bradycardia b. Rash c. Vomiting d. Fever e. Drooling f. Weakness

ANS: A, C, E, F Bradycardia, drooling, and weakness can all occur with cholinergic crisis. REF: Page 327

20. A nurse assesses a client admitted with deep partial-thickness and full-thickness burns on the face, arms, and chest. Which assessment finding should alert the nurse to a potential complication? a. Partial pressure of arterial oxygen (PaO2) of 80 mm Hg b. Urine output of 20 mL/hr c. Productive cough with white pulmonary secretions d. Core temperature of 100.6° F (38° C)

ANS: B A significant loss of fluid occurs with burn injuries, and fluids must be replaced to maintain hemodynamics. If fluid replacement is not adequate, the client may become hypotensive and have decreased perfusion of organs, including the brain and kidneys. A low urine output is an indication of poor kidney perfusion. The other manifestations are not complications of burn injuries. REF: 479

17. The nurse is preparing to care for a patient who has multiple sclerosis (MS). The nurse learns that the patient receives cyclophosphamide (Cytoxan). The nurse knows that this patient is in which stage of MS? a. Acute attack phase b. Chronic, progressive phase c. End-stage phase d. Remission-exacerbation phase

ANS: B Cyclophosphamide is used to treat MS patients who are in the chronic, progressive phase. REF: Page 330

4. The nurse is preparing a patient who will receive intermittent enteral nutrition at home with a hyperosmolar solution. What information will the nurse include when teaching this patient? a. How to perform the Valsalva maneuver b. The need to consume extra fluids between feedings c. The need to decrease dietary fiber d. The need to remain supine during infusion of the enteral solution

ANS: B Dehydration can occur if patients do not receive enough water during or between feedings, so patients should be taught to consume extra water. The Valsalva maneuver is taught to patients who receive TPN to prevent embolus. Enteral feedings can cause diarrhea, so decreased fiber may aggravate that. REF: Page 246

9. A patient reports weakness of the extremities and diplopia. The nurse knows that these symptoms are characteristic of which condition? a. Cerebral palsy (CP) b. Multiple sclerosis (MS) c. Myasthenia gravis (MG) d. Parkinson's disease (PD)

ANS: B Diplopia and weakness of the extremities are two symptoms of MS. CP is characterized by muscle spasticity. MG involves generalized weakness, especially of facial muscles and respiratory muscles. PD manifests as tremors and difficulty moving and walking. REF: Page 330

1. The nurse is preparing to administer enteral nutrition to a patient. Which assessment finding would prompt the nurse to hold the nutrition and notify the patient's provider? a. Blood pressure of 90/60 mm Hg b. Decreased bowel sounds c. A productive cough d. A temperature of 37.8° C

ANS: B Enteral nutrition requires adequate small bowel function with digestion, absorption, and gastrointestinal motility. The nurse should assess for abdominal distension and a decrease or absence of bowel sounds. Patients may still receive enteral feedings if hypotension, cough, or elevated temperature are present. REF: Page 244

3. The provider calculates the enteral nutrition needs for a nonambulatory patient and determines that the patient will need 300 mL of Ultracal every 4 hours. Which method of delivery will the nurse use to administer these feedings? a. 300 mL every 4 hours given via syringe as a 10-minute bolus b. 300 mL every 4 hours given via enteral pump as a 45-minute infusion c. 75 mL per hour via enteral pump as a continuous infusion d. 150 mL every 2 hours via gravity infusion

ANS: B Intermittent enteral feedings are an inexpensive and safe method of administering enteral nutrition and may be used when patients are nonambulatory. Three hundred to 400 mL of solution may be given and should infuse over 30 to 60 minutes. While bolus methods may be used for patients receiving 250 to 400 mL of solution, this method is not tolerated well by non-ambulatory patients and may cause nausea, vomiting, aspiration, abdominal cramping, and diarrhea. Continuous feedings are used for critically ill patients. Gravity feedings cannot be well-controlled and may infuse too fast or too slow. REF: Pages 245-246

14. The nurse is teaching a group of nursing students about multiple sclerosis (MS). Which statement by the nurse is correct? a. "MS is characterized by degeneration of neurons and nerves in the brain and spinal cord." b. "MS is characterized by lesions or plaques on myelin sheaths of nerves." c. "MS is characterized by neuritic plaques and neurofibrillary tangles in the CNS." d. "MS is characterized by weak muscles and decreased nerve impulses caused by decreased ACh."

ANS: B MS is characterized by lesions on myelin sheaths of nerves. REF: Page 330

5. The nurse is caring for a patient who has myasthenia gravis (MG) and is receiving pyridostigmine bromide (Mestinon). The nurse notes ptosis of both eyelids and observes that the patient has difficulty swallowing. What action will the nurse perform next? a. Contact the provider to request an order for atropine sulfate. b. Contact the provider to request an order for edrophonium chloride (Tensilon). c. Report signs of cholinergic crisis to the provider. d. Report signs of myasthenic crisis to the provider.

ANS: B Overdosing and underdoing of AChE inhibitors have similar symptoms: muscle weakness, dyspnea, and dysphagia. Edrophonium may be used to diagnose MG or to distinguish between myasthenic crisis and cholinergic crisis since it is a very short-acting AChE inhibitor. When given, if the symptoms are alleviated, the cause is myasthenic crisis; if symptoms worsen, it is cholinergic crisis. Since patients can have similar symptoms, the nurse cannot report one or the other to the provider without more information. REF: Pages 327-328

7. A student nurse is preparing morning medications for a client who had a stroke. The student plans to hold the docusate sodium (Colace) because the client had a large stool earlier. What action by the supervising nurse is best? a. Have the student ask the client if it is desired or not. b. Inform the student that the docusate should be given. c. Tell the student to document the rationale. d. Tell the student to give it unless the client refuses.

ANS: B Stool softeners should be given to clients with neurologic disorders in order to prevent an elevation in intracranial pressure that accompanies the Valsalva maneuver when constipated. The supervising nurse should instruct the student to administer the docusate. The other options are not appropriate. The medication could be held for diarrhea. REF: 942

10. A client's mean arterial pressure is 60 mm Hg and intracranial pressure is 20 mm Hg. Based on the client's cerebral perfusion pressure, what should the nurse anticipate for this client? a. Impending brain herniation b. Poor prognosis and cognitive function c. Probable complete recovery d. Unable to tell from this information

ANS: B The cerebral perfusion pressure (CPP) is the intracranial pressure subtracted from the mean arterial pressure: in this case, 60 - 20 = 40. For optimal outcomes, CPP should be at least 70 mm Hg. This client has very low CPP, which will probably lead to a poorer prognosis with significant cognitive dysfunction should the client survive. This data does not indicate impending brain herniation or complete recovery. REF: 949

17. The nurse is caring for a patient who is receiving total parenteral nutrition (TPN) and notes that the patient becomes dyspneic when transferring from the bed to a chair. The nurse auscultates rales in both lungs. Which action will the nurse take next? a. Ask the patient to perform the Valsalva maneuver. b. Decrease the TPN rate and request an order for a diuretic medication. c. Obtain an order for a chest radiograph and an antibiotic. d. Stop the TPN and request an order for intravenous isotonic dextrose.

ANS: B The patient who is being treated with TPN and has dyspnea and rales is experiencing fluid overload. The nurse should slow the rate of the TPN and request an order for a diuretic. Patients perform the Valsalva maneuver during bag changes to help prevent pulmonary emboli. Patients receiving TPN are not necessarily at risk for aspiration pneumonia. Intravenous isotonic dextrose is given after sudden interruption of TPN to prevent hypoglycemia. REF: Page 249

16. A nurse cares for a client with burn injuries from a house fire. The client is not consistently oriented and reports a headache. Which action should the nurse take? a. Increase the client's oxygen and obtain blood gases. b. Draw blood for a carboxyhemoglobin level. c. Increase the client's intravenous fluid rate. d. Perform a thorough Mini-Mental State Examination.

ANS: B These manifestations are consistent with moderated carbon monoxide poisoning. This client is at risk for carbon monoxide poisoning because he or she was in a fire in an enclosed space. The other options will not provide information related to carbon monoxide poisoning. REF: 474

1. Patients with which conditions would benefit from enteral feedings? (Select all that apply.) a. Burns of face, chest, and neck b. Cerebral palsy with severe dysphagia c. Crohn's disease d. Facial fractures e. Gluten enteropathy f. Stroke

ANS: B, D, F Patients with an intact, functioning gastrointestinal tract will benefit from enteral nutrition. Patients with extensive burns will need total parenteral nutrition (TPN) to prevent negative nitrogen balance. Patients with Crohn's disease and gluten enteropathy have malabsorption problems and will need TPN. REF: Page 244

13. The nurse is preparing to discontinue total parenteral nutrition (TPN) therapy for a patient who has been receiving TPN for several days. The nurse will contact the provider to discuss an order for a. antibiotics. b. intravenous insulin. c. isotonic dextrose. d. nasogastric feedings.

ANS: C Abruptly discontinuing TPN can lead to hypoglycemia. Patients should receive an isotonic dextrose solution for 12 to 24 hours after TPN is discontinued to prevent this reaction. Antibiotics are used when signs of infection are observed. Intravenous insulin would compound hypoglycemia. Nasogastric feedings are indicated if the patient needs continued feeding therapy and has an intact GI tract. REF: Page 248

11. The nurse is caring for a patient who has recurrent muscle spasms. The provider has ordered metaxalone (Skelaxin) to treat the spasms. The nurse learns that the patient has a history of drug and alcohol abuse. The nurse will contact the provider to discuss switching this patient to which medication? a. Carisoprodol (Soma) b. Chlorzoxazone (Parafon forte DSC) c. Cyclobenzaprine (Flexeril) d. Methocarbamol (Robaxin)

ANS: C Cyclobenzaprine is a muscle relaxant that does not cause drug dependence. The other muscle relaxants can cause drug dependence. REF: Page 332

3. The nurse teaches burn prevention to a community group. Which statement by a member of the group should cause the nurse the greatest concern? a. "I get my chimney swept every other year." b. "My hot water heater is set at 120 degrees." c. "Sometimes I wake up at night and smoke." d. "I use a space heater when it gets below zero."

ANS: C House fires are a common occurrence and often lead to serious injury or death. The nurse should be most concerned about a person who wakes up at night and smokes. The nurse needs to question this person about whether he or she gets out of bed to do so, or if this person stays in bed, which could lead to falling back asleep with a lighted cigarette. Although it is recommended to have chimneys swept every year, skipping a year does not pose as much danger as smoking in bed, particularly if the person does not burn wood frequently. Water heaters should be set below 140° F. Space heaters should be used with caution, and the nurse may want to ensure that the person does not allow it to get near clothing or bedding. REF: 472

5. A nurse assesses a client who has a burn injury. Which statement indicates the client has a positive perspective of his or her appearance? a. "I will allow my spouse to change my dressings." b. "I want to have surgical reconstruction." c. "I will bathe and dress before breakfast." d. "I have secured the pressure dressings as ordered."

ANS: C Indicators that the client with a burn injury has a positive perception of his or her appearance include a willingness to touch the affected body part. Self-care activities such as morning care foster feelings of self-worth, which are closely linked to body image. Allowing others to change the dressing and discussing future reconstruction would not indicate a positive perception of appearance. Wearing the dressing will assist in decreasing complications but will not enhance self-perception. REF: 488

6. The nurse dilutes an antibiotic before administering it through a patient's nasogastric tube. The patient asks why this is necessary. The nurse explains that diluting the antibiotic helps to a. improve absorption. b. improve hydration. c. prevent diarrhea. d. prevent emboli.

ANS: C Liquid medication must be properly diluted when given through a feeding tube because most liquid medications are hyperosmolar and can cause abdominal distention, cramping, vomiting, and diarrhea. Diluting the liquid medication does not change absorption, improve overall hydration, or prevent embolus formation. REF: Page 246

12. A patient who has been receiving total parenteral nutrition (TPN) for several days accidently removes the intravenous (IV) line. While waiting for the IV therapy nurse, the nurse caring for this patient will monitor for which complication? a. Air embolism b. Dehydration c. Hypoglycemia d. Infection

ANS: C Sudden interruption of TPN therapy can lead to hypoglycemia because of the sudden drop in glucose and the patient's continued increased insulin levels. Air embolism is a complication associated with changing TPN bags. Dehydration is not a complication of a sudden interruption of TPN. Infection is an ongoing concern, but the risk does not increase with a sudden interruption of TPN. REF: Page 248

26. A nurse is caring for four clients in the neurologic/neurosurgical intensive care unit. Which client should the nurse assess first? a. Client who has been diagnosed with meningitis with a fever of 101° F (38.3° C) b. Client who had a transient ischemic attack and is waiting for teaching on clopidogrel (Plavix) c. Client receiving tissue plasminogen activator (t-PA) who has a change in respiratory pattern and rate d. Client who is waiting for subarachnoid bolt insertion with the consent form already signed

ANS: C The client receiving t-PA has a change in neurologic status while receiving this fibrinolytic therapy. The nurse assesses this client first as he or she may have an intracerebral bleed. The client with meningitis has expected manifestations. The client waiting for discharge teaching is a lower priority. The client waiting for surgery can be assessed quickly after the nurse sees the client who is receiving t-PA, or the nurse could delegate checking on this client to another nurse. REF: 938

11. A nurse reviews the laboratory results for a client who was burned 24 hours ago. Which laboratory result should the nurse report to the health care provider immediately? a. Arterial pH: 7.32 b. Hematocrit: 52% c. Serum potassium: 6.5 mEq/L d. Serum sodium: 131 mEq/L

ANS: C The serum potassium level is changed to the degree that serious life-threatening responses could result. With such a rapid rise in potassium level, the client is at high risk for experiencing severe cardiac dysrhythmias and death. All the other findings are abnormal but do not show the same degree of severity; they would be expected in the emergent phase after a burn injury. REF: 477

8. A nurse prepares to administer intravenous cimetidine (Tagamet) to a client who has a new burn injury. The client asks, "Why am I taking this medication?" How should the nurse respond? a. "Tagamet stimulates intestinal movement so you can eat more." b. "It improves fluid retention, which helps prevent hypovolemic shock." c. "It helps prevent stomach ulcers, which are common after burns." d. "Tagamet protects the kidney from damage caused by dehydration."

ANS: C Ulcerative gastrointestinal disease (Curling's ulcer) may develop within 24 hours after a severe burn as a result of increased hydrochloric acid production and a decreased mucosal barrier. This process occurs because of the sympathetic nervous system stress response. Cimetidine is a histamine2 blocker and inhibits the production and release of hydrochloric acid. Cimetidine does not affect intestinal movement and does not prevent hypovolemic shock or kidney damage. REF: 470

8. The nurse is preparing to hang a new bag for a patient who is receiving total parenteral nutrition (TPN). During this procedure, the nurse will instruct the patient to take a deep breath and then perform which action? a. Exhale slowly and bear down. b. Exhale slowly to the count of 10. c. Hold the breath and bear down. d. Take several rapid, shallow breaths.

ANS: C Valsalva's maneuver is performed by taking a breath, holding it, and bearing down. Patients are instructed to perform this maneuver in order to prevent the formation of air emboli. REF: Page 250

18. A nurse assesses bilateral wheezes in a client with burn injuries inside the mouth. Four hours later the wheezing is no longer heard. Which action should the nurse take? a. Document the findings and reassess in 1 hour. b. Loosen any constrictive dressings on the chest. c. Raise the head of the bed to a semi-Fowler's position. d. Gather appropriate equipment and prepare for an emergency airway.

ANS: D Clients with severe inhalation injuries may sustain such progressive obstruction that they may lose effective movement of air. When this occurs, wheezing is no longer heard, and neither are breath sounds. These clients can lose their airways very quickly, so prompt action is needed. The client requires establishment of an emergency airway. Swelling usually precludes intubation. The other options do not address this emergency situation. REF: 474

1. The registered nurse assigns a client who has an open burn wound to a licensed practical nurse (LPN). Which instruction should the nurse provide to the LPN when assigning this client? a. "Administer the prescribed tetanus toxoid vaccine." b. "Assess the client's wounds for signs of infection." c. "Encourage the client to breathe deeply every hour." d. "Wash your hands on entering the client's room."

ANS: D Infection can occur when microorganisms from another person or from the environment are transferred to the client. Although all of the interventions listed can help reduce the risk for infection, handwashing is the most effective technique for preventing infection transmission. REF: 466

13. A nurse cares for a client who has burn injuries. The client's wife asks, "When will his high risk for infection decrease?" How should the nurse respond? a. "When the antibiotic therapy is complete." b. "As soon as his albumin levels return to normal." c. "Once we complete the fluid resuscitation process." d. "When all of his burn wounds have closed."

ANS: D Intact skin is a major barrier to infection and other disruptions in homeostasis. No matter how much time has passed since the burn injury, the client remains at high risk for infection as long as any area of skin is open. Although the other options are important goals in the client's recovery process, they are not as important as skin closure to decrease the client's risk for infection. REF: 466

13. The nurse is performing an admission assessment on a patient who has been taking carisoprodol (Soma) for 3 weeks to treat muscle spasms. The patient reports that the muscle spasms have resolved. The nurse will contact the provider to discuss a. changing to cyclobenzaprine (Flexeril). b. continuing the carisoprodol for 1 more week. c. discontinuing the carisoprodol now. d. ordering a taper of the carisoprodol.

ANS: D Muscle relaxants can cause drug dependence and should not be withdrawn abruptly. The nurse should discuss a drug taper. REF: Page 333

9. Which patient is most likely to be a candidate for total parenteral nutrition (TPN) rather than enteral nutrition? a. A patient who is comatose after having had a stroke b. A patient who has a fractured mandible following a motor vehicle accident c. A patient who has cerebral palsy and severe dysphagia d. A patient who is pregnant and has intractable hyperemesis gravidarum

ANS: D The patient who is vomiting will be unable to tolerate enteral nutrition. Enteral feedings require a functioning gastrointestinal tract. TPN is more costly and does not carry significant benefits when compared with risks, so it should only be used when enteral nutrition cannot be used. REF: Page 244

3. A nurse receives a report on a client who had a left-sided stroke and has homonymous hemianopsia. What action by the nurse is most appropriate for this client? a. Assess for bladder retention and/or incontinence. b. Listen to the client's lungs after eating or drinking. c. Prop the client's right side up when sitting in a chair. d. Rotate the client's meal tray when the client stops eating.

ANS: D This condition is blindness on the same side of both eyes. The client must turn his or her head to see the entire visual field. The client may not see all the food on the tray, so the nurse rotates it so uneaten food is now within the visual field. This condition is not related to bladder function, difficulty swallowing, or lack of trunk control. REF: 936

12. The nurse provides teaching to a patient who will begin taking cyclobenzaprine (Flexeril) to treat muscle spasms. Which statement by the patient indicates a need for further teaching? a. "I may experience dizziness and drowsiness when I take this drug." b. "I should not consume alcohol while taking this medication." c. "I should take this medication with food to decrease stomach upset." d. "I will take this medication for three weeks and then stop taking it."

ANS: D This medication should not be stopped abruptly. Patients may experience dizziness and drowsiness. Alcohol will compound the central nervous system sedative effects. To decrease gastrointestinal upset, the nurse should counsel the patient to take it with food. REF: Page 332

1. An emergency room nurse cares for a client admitted with a 50% burn injury at 10:00 this morning. The client weighs 90 kg. Using the Parkland formula, calculate the rate at which the nurse should infuse intravenous fluid resuscitation when started at noon. (Record your answer using a whole number.) _____ mL/hr

ANS: 1500 mL/hr The Parkland formula is 4 mL/kg/% total body surface area burn. This client needs 18,000 mL of fluid during the first 24 hours postburn. Half of the calculated fluid replacement needs to be administered during the first 8 hours after injury, and half during the next 16 hours. This client was burned at 10:00 AM, and fluid was not started until noon. Therefore, 9000 mL must be infused over the next 6 hours at a rate of 1500 mL/hr to meet the criteria of receiving half the calculated dose during the first 8 postburn hours. REF: 478

2. An emergency room nurse implements fluid replacement for a client with severe burn injuries. The provider prescribes a liter of 0.9% normal saline to infuse over 1 hour and 30 minutes via gravity tubing with a drip factor of 30 drops/mL. At what rate should the nurse administer the infusion? (Record your answer using a whole number and rounding to the nearest drop.) ____ drops/min

ANS: 333 drops/min 1000 mL divided by 90 minutes, then multiplied by 30 drops, equals 333 drops/min. REF: 478

7. The nurse is caring for a patient who is receiving total parenteral nutrition (TPN). The nurse will carefully monitor this patient for which symptom(s)? a. Coughing and shortness of breath b. Decreased breath sounds c. Diarrhea d. Nausea and abdominal distension

ANS: A TPN with IV therapy is prone to air embolism. Symptoms of air embolism are coughing and dyspnea. Decreased breath sounds occur with aspiration, which is a complication of nasogastric feedings. Diarrhea, nausea, and abdominal distension occur with nasogastric feedings. REF: Page 249

19. The nurse is preparing to administer methocarbamol (Robaxin) to a patient who is experiencing acute muscle spasms. The nurse notes that the patient's urine has turned black. What will the nurse do? a. Administer the next dose of methocarbamol since this is a harmless side effect. b. Contact the provider to discuss changing to cyclobenzaprine (Flexeril). c. Obtain an order for a complete blood count to evaluate blood loss. d. Request an order for liver function tests since this indicates hepatotoxicity.

ANS: A Urine may turn green, brown, or black in patients taking methocarbamol, and this is a harmless side effect. There is no need to change medications or order lab tests. REF: Page 331

20. The nurse assumes care for a patient who is being treated with enteral feeding. When performing the initial assessment, the nurse finds the patient supine and asleep. The nurse will perform which action? a. Elevate the head of the bed 30 degrees. b. Flush the tubing with water. c. Position the patient to the left side. d. Temporarily discontinue the infusion.

ANS: A When administering an enteral feeding, the nurse should elevate the head of the patient's bed 30 degrees. REF: Page 246

4. A nurse cares for an older client with burn injuries. Which age-related changes are paired appropriately with their complications from the burn injuries? (Select all that apply.) a. Slower healing time - Increased risk for loss of function from contracture formation b. Reduced inflammatory response - Deep partial-thickness wound with minimal exposure c. Reduced thoracic compliance - Increased risk for atelectasis d. High incidence of cardiac impairments - Increased risk for acute kidney injury e. Thinner skin - May not exhibit a fever when infection is present

ANS: A, C, D Slower healing time will place the older adult client at risk for loss of function from contracture formation due to the length of time needed for the client to heal. A pre-existing cardiac impairment increases risk for acute kidney injury from decreased renal blood flow, and reduced thoracic compliance places the client at risk for atelectasis. Reduced inflammatory response places the client at risk for infection without a normal response, including fever. Clients with thinned skin are at greater risk for deeper wounds from minimal exposure. REF: 474

2. The nurse is caring for a client with an acute burn injury. Which action should the nurse take to prevent infection by autocontamination? a. Use a disposable blood pressure cuff to avoid sharing with other clients. b. Change gloves between wound care on different parts of the client's body. c. Use the closed method of burn wound management for all wound care. d. Advocate for proper and consistent handwashing by all members of the staff.

ANS: B Autocontamination is the transfer of microorganisms from one area to another area of the same client's body, causing infection of a previously uninfected area. Although all techniques listed can help reduce the risk for infection, only changing gloves between performing wound care on different parts of the client's body can prevent autocontamination. REF: 485

11. A patient who has been receiving continuous enteral nutrition has had several large, watery stools. The nurse will contact the provider to discuss which intervention? a. Administering antidiarrheal medications b. Slowing the rate of infusion c. Starting total parenteral nutrition d. Thickening the nutrition solution

ANS: B The most common cause of diarrhea during a feeding is dumping syndrome as a result of rapid feed infusion. Slowing the feeding is the appropriate initial action. Antidiarrheal medications are not indicated unless slowing the infusion fails. Total parenteral nutrition is not indicated for patients with a functioning gastrointestinal tract. Thickening the solution will increase the solute load and increase the risk for diarrhea. REF: Page 246

10. A nurse receives new prescriptions for a client with severe burn injuries who is receiving fluid resuscitation per the Parkland formula. The client's urine output continues to range from 0.2 to 0.25 mL/kg/hr. Which prescription should the nurse question? a. Increase intravenous fluids by 100 mL/hr. b. Administer furosemide (Lasix) 40 mg IV push. c. Continue to monitor urine output hourly. d. Draw blood for serum electrolytes STAT.

ANS: B The plan of care for a client with a burn includes fluid and electrolyte resuscitation. Furosemide would be inappropriate to administer. Postburn fluid needs are calculated initially by using a standardized formula such as the Parkland formula. However, needs vary among clients, and the final fluid volume needed is adjusted to maintain hourly urine output at 0.5 mL/kg/hr. Based on this client's inadequate urine output, fluids need to be increased, urine output needs to be monitored hourly, and electrolytes should be evaluated to ensure appropriate fluids are being infused. REF: 478

16. The nurse is caring for a patient who is receiving total parenteral nutrition (TPN). The patient reports nausea, headache, and thirst. The nurse will contact the provider to discuss a. giving acetaminophen for headache pain. b. obtaining a serum glucose level. c. ordering an antiemetic to prevent vomiting. d. starting intravenous isotonic dextrose.

ANS: B This patient shows signs of hyperglycemia, which is a common adverse effect of TPN. The nurse should request an order for serum glucose. Symptoms should not be treated without first determining the underlying cause. Isotonic dextrose is given to prevent hypoglycemia. REF: Page 249

19. A patient receiving total parenteral nutrition (TPN) begins having cough and dyspnea. The nurse auscultates rales and notes neck vein engorgement and weight gain. The nurse suspects that the patient is experiencing which condition? a. Air embolism b. Fluid overload c. Pneumonia d. Pneumothorax

ANS: B This patient shows signs of overload, characterized by pulmonary edema with cough and dyspnea, neck vein engorgement, and weight gain. REF: Page 249

19. A nurse uses the rule of nines to assess a client with burn injuries to the entire back region and left arm. How should the nurse document the percentage of the client's body that sustained burns? a. 9% b. 18% c. 27% d. 36%

ANS: C According to the rule of nines, the posterior trunk, anterior trunk, and legs each make up 18% of the total body surface. The head, neck, and arms each make up 9% of total body surface, and the perineum makes up 1%. In this case, the client received burns to the back (18%) and one arm (9%), totaling 27% of the body. REF: 476

9. A nurse cares for a client with a burn injury who presents with drooling and difficulty swallowing. Which action should the nurse take first? a. Assess the level of consciousness and pupillary reactions. b. Ascertain the time food or liquid was last consumed. c. Auscultate breath sounds over the trachea and bronchi. d. Measure abdominal girth and auscultate bowel sounds.

ANS: C Inhalation injuries are present in 7% of clients admitted to burn centers. Drooling and difficulty swallowing can mean that the client is about to lose his or her airway because of this injury. Absence of breath sounds over the trachea and bronchi indicates impending airway obstruction and demands immediate intubation. Knowing the level of consciousness is important in assessing oxygenation to the brain. Ascertaining the time of last food intake is important in case intubation is necessary (the nurse will be more alert for signs of aspiration). However, assessing for air exchange is the most important intervention at this time. Measuring abdominal girth is not relevant in this situation. REF: 474

4. A nurse cares for a client who has facial burns. The client asks, "Will I ever look the same?" How should the nurse respond? a. "With reconstructive surgery, you can look the same." b. "We can remove the scars with the use of a pressure dressing." c. "You will not look exactly the same but cosmetic surgery will help." d. "You shouldn't start worrying about your appearance right now."

ANS: C Many clients have unrealistic expectations of reconstructive surgery and envision an appearance identical or equal in quality to the preburn state. The nurse should provide accurate information that includes something to hope for. Pressure dressings prevent further scarring; they cannot remove scars. The client and the family should be taught the expected cosmetic outcomes. REF: 488

23. After assessing an older adult client with a burn wound, the nurse documents the findings as follows: Vital Signs Laboratory Results Wound Assessment Heart rate: 110 beats/min Blood pressure: 112/68 mm Hg Respiratory rate: 20 breaths/min Oxygen saturation: 94% Pain: 3/10 Red blood cell count: 5,000,000/mm3 White blood cell count: 10,000/mm3 Platelet count: 200,000/mm3 Left chest burn wound, 3 cm ´ 2.5 cm ´ 0.5 cm, wound bed pale, surrounding tissues with edema present Based on the documented data, which action should the nurse take next? a. Assess the client's skin for signs of adequate perfusion. b. Calculate intake and output ratio for the last 24 hours. c. Prepare to obtain blood and wound cultures. d. Place the client in an isolation room.

ANS: C Older clients have a decreased immune response, so they may not exhibit signs that their immune system is actively fighting an infection, such as fever or an increased white blood cell count. They also are at higher risk for sepsis arising from a localized wound infection. The burn wound shows signs of local infection, so the nurse should assess for this and for systemic infection before the client manifests sepsis. Placing the client in an isolation room, calculating intake and output, and assessing the client's skin should all be implemented but these actions do not take priority over determining whether the client has an infection. REF: 474

18. Which muscle relaxant is used in surgery as a skeletal muscle relaxant? a. Baclofen (Lioresal) b. Chlorzoxazone (Parafon forte) c. Pancuronium bromide (Pavulon) d. Methocarbamol (Robaxin)

ANS: C Pancuronium bromide is used as a depolarizing muscle relaxant during anesthesia. REF: Page 331

14. The nurse is caring for a patient with severe burns who will begin receiving total parenteral nutrition (TPN). The patient asks why TPN is necessary. The nurse explains that TPN is used for which reason? a. To minimize pulmonary complications b. To prevent hyperglycemia and fluid overload c. To promote wound healing and maintain cell integrity d. To restore fluid and electrolyte imbalance

ANS: C TPN is indicated for patients with severe burns who are in negative nitrogen balance. TPN enhances wound healing and provides the nutrients necessary to prevent cellular catabolism. While some pulmonary complications, such as aspiration pneumonia, do not occur with TPN, there is a risk of air embolism. Hyperglycemia and fluid overload may occur. REF: Page 248

17. A nurse teaches a client being treated for a full-thickness burn. Which statement should the nurse include in this client's discharge teaching? a. "You should change the batteries in your smoke detector once a year." b. "Join a program that assists burn clients to reintegration into the community." c. "I will demonstrate how to change your wound dressing for you and your family." d. "Let me tell you about the many options available to you for reconstructive surgery."

ANS: C Teaching clients and family members to perform care tasks such as dressing changes is critical for the progressive goal toward independence for the client. All of the other options are important in the rehabilitation stage. However, dressing changes have priority. REF: 489

22. A nurse reviews the following data in the chart of a client with burn injuries: Admission Notes Wound Assessment 36-year-old female with bilateral leg burns NKDA Health history of asthma and seasonal allergies Bilateral leg burns present with a white and leather-like appearance. No blisters or bleeding present. Client rates pain 2/10 on a scale of 0-10. Based on the data provided, how should the nurse categorize this client's injuries? a. Partial-thickness deep b. Partial-thickness superficial c. Full thickness d. Superficial

ANS: C The characteristics of the client's wounds meet the criteria for a full-thickness injury: color that is black, brown, yellow, white, or red; no blisters; minimal pain; and firm and inelastic outer layer. Partial-thickness superficial burns appear pink to red and are painful. Partial-thickness deep burns are deep red to white and painful. Superficial burns are pink to red and are also painful. REF: 467

12. A nurse assesses a client who has burn injuries and notes crackles in bilateral lung bases, a respiratory rate of 40 breaths/min, and a productive cough with blood-tinged sputum. Which action should the nurse take next? a. Administer furosemide (Lasix). b. Perform chest physiotherapy. c. Document and reassess in an hour. d. Place the client in an upright position.

ANS: D Pulmonary edema can result from fluid resuscitation given for burn treatment. This can occur even in a young healthy person. Placing the client in an upright position can relieve lung congestion immediately before other measures can be carried out. Although Lasix may be used to treat pulmonary edema in clients who are fluid overloaded, a client with a burn injury will lose a significant amount of fluid through the broken skin; therefore, Lasix would not be appropriate. Chest physiotherapy will not get rid of fluid. REF: 475

16. The nurse is performing a health history on a patient who has multiple sclerosis. The patient reports episodes of muscle spasticity and recurrence of muscle weakness and diplopia. The nurse will expect this patient to be taking which medication? a. Adrenocorticotropic hormone (ACTH) b. Cyclophosphamide (Cytoxan) c. Cyclobenzaprine (Flexeril) d. Interferon-B (IFN-B)

ANS: D This patient is showing signs of remission and exacerbation of MS symptoms. Interferon is used to treat this phase. ACTH is used for acute attacks. Cyclophosphamide is used for chronic, progressive symptoms. Cyclobenzaprine is a centrally acting muscle relaxant that is used for muscle spasms to decrease pain and increase range of motion.
