Take all of the antibiotics as directed until completely gone. 2. Eat a high-protein, high-caloric diet 3. Exercise daily, beginning with active ROM 4. Get at least 8 hours of sleep per night with frequent rest periods.

1. Take all of the antibiotics as directed until completely gone Rationale: It is essential that the client recovering from bacterial meningitis take all the prescribed antibiotic as directed. Failure to do so puts the client at risk for relapse of symptoms and contributes to development of bacterial resistance to antibiotics.

A nurse is caring for a client who has a traumatic brain injury and assumes a decerebrate posture in response to noxious stimuli. Which of the following reactions should the nurse anticipate when drawing a blood sample? 1. The client rigidly extends his arms. 2. The client internally flexes his wrists 3. The client curls into a fetal position 4. The client internally rotates his legs.

1. The client rigidly extends his arms. Rationale: A client who exhibits a decerebrate posture rigidly extends and pronates his four extremities and externally rotates his wrists. Decerebrate posturing indicates severe brain stem injury and late neurologic decline.

A nurse is assessing a client who has a closed head injury and has received mannitol for manifestations of increased intracranial pressure (ICP). Which of the following findings should indicate to the nurse that the medication is having a therapeutic effect? 1. The client's serum osmolarity is 310 mOsm/L. 2. The client's pupils are dilated. 3. The client's heart rate is 56/min. 4. The client is restless.

1. The client's serum osmolarity is 310 mOsm/L. Rationale: Mannitol is an osmotic diuretic used to reduce cerebral edema by drawing water out of the brain tissue. A serum osmolarity of 310 mOsm/L is desired. A decrease in cerebral edema should result in a decrease in ICP.

A commode is observed at the bedside 2. A fluid restriction chart is on the refrigerator 3. Metamucil is on the kitchen counter. 4. Hand weights are next to the couch 5. There is a small scatter rug at the side of the bed

2. A fluid restriction chart is on the refrigerator 5. There is a small scatter rug at the side of the bed Rationale: Fluid restriction may be needed in the period immediately following a stroke, but this is not necessary after discharge to home. Small rugs can increase the risk for falls and should be removed.

A client calls the telephone triage nurse to report fever, nausea, chills and malaise. The nurse instructs the client to come immediately to the emergency department after the client shares which additional data? 1. A bad headache 2. A stiff sore neck 3. A heart rate of 106 4. A roommate with the same symptoms.

2. A stiff sore neck Rationale: A stiff sore neck is a sign of meningeal irritation and possible meningitis. The nurse may further inquire if flexion of the neck causes pain and the hip and knee to flex (Brudzinski's sign) and how high the fever is.

When assessing the client with meningitis, the nurse looks for which manifestations as a frequent first sign of increased intracranial pressure? 1. A rising systolic blood pressure 2. Change in mood or attention level 3. Irregular respiratory rate and depth 4. Bounding radial pulse

2. Change in mood or attention level Rationale: The first signs of increased intracranial pressure are often subtle changes in level of consciousness

A nurse is assessing a client who is unconscious and has a rhythmical breathing pattern of rapid deep respirations, following by rapid shallow respirations, alternating with periods of apnea. The nurse should document that the client is experiencing which of the following types of respirations? 1. Orthopnea 2. Cheyne-Stokes 3. Paradoxical 4. Kussmaul

2. Cheyne-Stokes Rationale: Cheyne-Stokes respirations is a breathing pattern of deep to shallow breaths, following by periods of apnea. Cheyne-Stokes respirations can be the result of a drug overdose or increased intracranial pressure and can precede death.

The client recently diagnosed with Guillain Barre syndrome is drooling and having difficulty swallowing secretions. When the family asks why this occurs, the nurse indicates that which of the following is the cause? 1. Obstructed blood flow to the midbrain 2. Demyelination of cranial nerves responsible for swallow and gag reflex 3. Enlargement of the parotid and salivary glands 4. Deficiency in thiamine and pyridoxine in the central nervous system.

2. Demyelination of cranial nerves responsible for swallow and gag reflex Rationale: Guillain-Barre syndrome is an acute demyelinating disorder that less commonly may present with initial weakness in the cranial nerves that progresses downward. Impairment of cranial nerve IX and X will affect swallowing.

A nurse in a rehabilitation center is performing an assessment for a client who is recovering from a left-hemisphere stroke. Which of the following findings should the nurse expect? 1. Reduced left-side motor function 2. Difficulty with speech 3. Impulsive behavior 4. Neglect of the left side of the body

2. Difficulty with speech Rationale: The left hemisphere of the brain is usually the dominant side and is responsible for language. This is always true for right-handed clients and for the majority of left-handed clients. Since this client is recovering from a left-hemisphere stroke, the nurse should anticipate that the client will have aphasia and require speech therapy to establish communication.

The nurse in the ED documents that the newly admitted client is "postictal upon transfer." What did the nurse observe? 1. Yellowing of the skin due to a liver condition 2. Drowsy or confused state following a seizure 3. Severe itching of the eyes from an allergic reaction 4. Abnormal sensations including tingling of the skin

2. Drowsy or confused state following a seizure. Rationale: The client had experienced a tonic-clonic seizure recently and is now in a state of deep relaxation and is breathing quietly. During this period the client may be unconscious or awakes gradually, but is often confused and disoriented. Often the client is amnesic regarding the seizure.

The client has right homonymous hemianopia following an ischemic stroke. The nurse asks the NA to help the client with meals knowing that this problem may result in which client response? 1. Tendency to fall to the contralateral side 2. Eating food on only half of the plate 3. Using the silverware inappropriately 4. Choking when swallowing any liquids

2. Eating food on only half of the plate Rationale: Homonymous hemianopia (hemianopsia) is a visual field abnormality that results in blindness in half of the visual field in the same side of both eyes. It results from damage to the optic tract or occipital lobe.

A nurse is reviewing the laboratory results of a lumbar puncture (LP) for a client who has manifestations of bacterial meningitis. Which of the following findings should the nurse expect? 1. Elevated glucose 2. Elevated protein 3. Presence of RBCs 4. Presence of D-dimer

Instilling artificial tears in the eyes every 1 to 2 hours 3. Ensuring the client's contact lenses are on while awake 4. Providing sunglasses when client is outside

2. Instilling artificial tears in the eyes every 1 to 2 hours Rationale: Corneal abrasion in the client with myasthenia graves is caused by dryness of the cornea from inability to close the eyelids and blink. It I can be prevented by application of artificial tears every 1 to 2 hours.

A nurse is providing discharge teaching to the family of a client who has a new diagnosis of a seizure disorder. The nurse should instruct the client's family to take which of the following actions first in the event of a seizure? 1. Reorient the client. 2. Protect the client's head. 3. Loosen constrictive clothing. 4. Turn the client on his side.

2. Protect the client's head. Rationale: The nurse should apply the safety and risk reduction priority-setting framework. This framework assigns priority to the factor or situation posing the greatest safety risk to the client. When there are several risks to client safety, the one posing the greatest threat is the highest priority. The nurse should use Maslow's Hierarchy of Needs, the ABC priority-setting framework, or nursing knowledge to identify which risk poses the greatest threat to the client. The client is at greatest risk for injury from hitting his head; therefore, the first action is to protect the client's head from injury.

The nurse is assisting the client who sustained a C5 SCI to cough using the quad coughing technique with which actions? select all that apply. 1. Places a suction catheter in the client's oral cavity to stimulate the cough reflex 2. Puts hands on the upper abdomen, has client inhale; pushes upward during a cough 3. Cups the hands and percusses the client's anterior, lateral, and posterior lung fields. 4. Hyperoxygenates the client by using a resuscitation bag to deliver 100% oxygen 5. Elevates the head of the bed to a high Fowler's position if the client is sitting in bed.

2. Puts hands on the upper abdomen, has client inhale, pushes upward during a cough 5. Elevates the head of the bed to a high Fowler's position if the client is sitting in bed. Rationale:(2) The nurse's hand placement and pushing upward during a cough help to overcome the impaired diaphragmatic function that occurs with a C5 SCI (5) Elevating the head of the bed will promote lung expansion, thus enabling a stronger cough

The nursing assesses the client, who was inured in a diving accident 2 hours earlier. The client is breathing independently but has no movement or muscle tone from below the area of injury. A CT scan reveals a fracture of the C4 cervical vertebra. The nurse should plan interventions for which problems? 1. Complete spinal cord transection 2. Spinal shock 3. An upper motor neuron injury 4. Quadriplegia

2. Spinal Shock Rationale: The client is experiencing spinal shock that manifests within a few hours after the injury. Hypotension, flaccid paralysis and absence of muscle contractions occur. Spinal shock lasts 7 to 20 days, and the sci cannot be classified accurately until spinal shock resolves.

The nurse is caring for the client who has severe craniocerebral trauma. Which finding indicates that the client is developing DI? 1. Blood glucose level at 230 mg/dL 2. Urinary output 1500 mL over 4 hours 3. Urine specific gravity 1.042 4. Somnolent when previously alert

2. Urinary output 1500 mL over 4 hours Rationale: The lack of ADH that occurs in DI prevents excepting a large amount of pale, diluted urine.

Spinal precautions are ordered for the client that sustained a neck injury during an MVA. The client has yet to be cleared that there is no cervical fracture. Which action is the nurse's priority when receiving the client in the ED? 1. Assessing the client using the Glasgow Coma Scale (GCS) 2. Assessing the level of sensation in the client's extremities. 3. Checking that the cervical collar was correctly placed by EMS (prevent injury) 4. Applying anti-embolism nose to the client's lower extremities

3. Checking that the cervical collar was correctly placed by EMS Rationale: Maintaining the correct placement of the cervical collar will keep the. client's head and neck in a neutral position and prevent further injury if a spinal fracture or SCI is present. Because ensuring that the cervical collar is correctly placed will prevent further injury, it is priority.

The nurse learns in report that the client admitted with a vertebral fracture has a halo external fixation devise in place. Which intervention should be nurse plan? 1. Ensure the traction weight hangs freely 2. Remove the vest from the device at bedtime 3. Cleanse sites where the pins enter the skull 4. screw the pins in the skull daily to tighten.

3. Cleanse sites where the pins enter the skull. Rationale:A halo exert fixation device is a static devise that consists of "halo" that is screwed into the skull by four pins. It is attached to a vest that the client wears. The device provides immobilization ad stability to the spinal cord while healing occurs with or widened surgical intervention. Care includes inspection and cleansing of the pins sites.

A 76-year old woman arrives at the emergency department by ambulance with a possible stroke. Vital signs are pulse 90, blood pressure 150/100, respirations 20. Thirty minutes later, vital signs are pulse 78, blood pressure 170/90, respirations 24 and irregular. The nurse should take which action at this time? 1. Ask the woman to describe how she's feeling. 2. check the client's phenytoin (dilantin) level 3. Get an order to decrease the rate of IV fluids. 4. Offer the client clear liquids to prevent dehydration.

3. Get an order to decrease the rate of IV fluids. Rationale: The client is showing signs of rising intracranial pressure, and reducing the rate of IV fluids prevents hypervolemia that would worsen the rising the intracranial pressure.

A nurse is assessing a client who is admitted to the facility for observation following a closed head injury. Which of the following is the priority assessment data the nurse should collect to determine a change in the client's neurologic status? 1. Vital signs 2. Body posture 3. Level of consciousness 4. Examination of pupils

3. Level of consciousness The nurse should apply the urgent vs. non-urgent priority-setting framework. Using this framework, the nurse should consider urgent needs the priority because they pose more of a risk to the client. The nurse might also use Maslow's Hierarchy of Needs, the ABC priority-setting framework, or nursing knowledge to identify the most urgent finding. Therefore, the priority assessment is level of consciousness. A change in the client's level of consciousness can be the first indication of a change in neurologic status.

What would the nurse do as priority when caring for the client with myasthenia graves to minimize the risk for complications of the disease? 1. Inspect for hemorrhage. 2. Assess for viral pneumonia 3. Offer to cut the client's food as needed 4. Provide the client with a bedside commode

3. Offer to cut the client's food as needed Rationale: When the muscles involved in chewing and swallowing, as well as the diaphragm and intercostal muscles, are weak the client may aspirate or experience poor gas exchange; both increase the risk for pneumonia. Options that protect the airway always have highest priority.

A nurse in an acute care facility is preparing to admit a client who has myasthenia graves. Which of the following supplies should the nurse place at the client's bedside? 1. Metered-dose inhaler 2. Continuous passive motion machine 3. Oral-nasal suction equipment 4. External defibrillator pads

3. Oral-nasal suction equipment Rationale: The client who has myasthenia graves is at risk for aspiration because of progressive weakness of the oropharyngeal muscles. Myasthenia graves causes muscle weakness due to an autoimmune disease that affects the acetylcholine receptors. The nurse should place oxygen and oral-nasal suction equipment at the bedside in the event of aspiration or respiratory distress.

3. Remove nearby objects that could lead to client injury 5. Note the length and progression of the seizure. Rationale: The nurse's priority is to protect the client from injury. The nurse would note and then document when the seizure began, how it progressed, when it ended, and associated client findings

A nurse is caring for a client who is postoperative following a frontal craniotomy. The nurse should place the client in which of the following positions? 1. Trendelenburg 2. Prone 3. Semi-Fowler's 4. Sims'

3. Semi-Fowler's Rationale: To prevent an increase in intracranial pressure, the nurse should position the client with his head midline and the head of the bed elevated 30 degrees. This positioning permits blood flow to the client's brain while allowing venous drainage, thereby decreasing the postoperative risk of increased intracranial pressure.

A hospitalized client diagnosed with seizures has a vagus nerve stimulation (VNS) device implanted. The nurse determines that the VNS is working properly when making which observation? 1. It stimulated a heartbeat when bradycardia occurred during a seizure 2. It defibrillated a lethal rhythm that occurred during the client's seizure. 3. The client activates the VNS devise to stop a seizure from occurring 4. The client activates the device at seizure onset to prevent aspiration.

3. The client activates the VNS device to stop a seizure from occurring Rationale: A VNS is a medical device that is implanted in the chest and stimulates the vagus nerve to control seizures unresponsive to medical treatment. Clients who experience auras before a seizure use a magnet to activate the VNS to stop the seizure.

A nurse is assessing a client who has Guillain-Barre syndrome. Which of the following findings should the nurse expect? 1. Tonic-clonic seizures 2. Report of a severe headache 3. Weakness of the lower extremities 4. Decreased level of consciousness

3. Weakness of the lower extremities Guillain-Barre syndrome, also called acute inflammatory demyelinating polyneuropathy, is an inflammatory disorder of the peripheral nerves. It is characterized by the rapid onset of ascending weakness and paralysis, starting at the lower extremities, and can advance to the upper extremities.

Which instructions would the nurse give to a client with multiple sclerosis who has urinary retention? 1. "Run water whenever you experience difficulty initiating urination." 2. "Decrease your fluid intake to prevent urgency." 3. "Drink a caffeinated beverage to promote the ability to form urine." 4. "Catheterize your bladder according to the schedule we discussed."

4. "Catheterize your bladder according to the schedule we discussed." Rationale: Urinary retention in the client with multiple sclerosis is a sequela of impaired conduct of nerves innervating the bladder. Performing self-catheterization will drain the bladder and help prevent urinary tract infection.

When applying nailed pressure, the client's body suddenly tiffins, the eyes roll upward, and there is an increase in salivation and loss of swallowing reflex. Which observation should the nurse document? 1. Decerebrate posturing observed 2. Decorticate posturing observed 3. Positive Kernig's sign observed 4. Seizure activity observed

4. Seizure activity observed Rationale: Body stiffening eye rolled upward, increase in salivation, and a loss of swallowing reflex are signs consistent with the tonic phase of tonic-clonic seizure. This phase is followed by the clonic phase with violent muscle contraction.

A nurse is assessing a client who is postoperative following a craniotomy and has a urine output of 600 mL/hr. The nurse suspects the client has manifestations of diabetes insidious (DI). Which of the following laboratory values should the nurse plan to obtain to assess for DI? 1. Blood urea nitrogen (BUN) 2. Blood glucose 3. Urine Ketones 4. Specific gravity

4. Specific gravity Diabetes insipidus is caused by damage to the hypothalamus or the pituitary gland as a result of cranial surgery, infection, or a tumor. It is a condition in which an inadequate amount of antidiuretic hormone is released and results in polyuria. A low specific gravity (1.001 to 1.003) is a manifestation of diabetes insipidus

A nurse is reviewing the medical history of a client who is scheduled for a magnetic resonance imaging (MRI) examination of the cervical vertebra. The nurse should alert the provider to which of the following information in the client's history that is a contraindication to the procedure? 1. The client has a new tattoo 2. The client is unable to sit upright. 3. The client has a history of peripheral vascular disease. 4. The client has a pacemaker.

4. The client has a pacemaker. An MRI uses strong magnets and radio waves that are evaluated using computer technology to view three-dimensional images of the body. Since an MRI is magnetically generated, it is not indicated for use in the presence of certain medical implants. Clients who have cerebral aneurysm clips, cardiac pacemakers, or internal defibrillators cannot undergo an MRI because the strong magnetic force can interfere with these devices and obscure surrounding anatomical structures.

The client diagnosed with Guillain-Barre syndrome is scheduled to receive plasmapheresis treatments. The client's spouse asks the nurse about the purpose of plasmapheresis. Which explanation is correct? 1. "Plasmapheresis removes excess fluid from the bloodstream." 2. "Plasmapheresis will increase the protein levels in the blood." 3. "Plasmapheresis removes simulating antibodies from the blood." 4. "Plasmapheresis infuses lipoproteins to restore the myelin sheath."

(3) "Plasmapheresis removes simulating antibodies from the blood." Rationale: Plasmapheresis is a procedure in which harmful antibodies are removed from the blood. During the procedure, blood is removed from he client, the plasma is separated, and blood cells without the plasma are returned to the client.

The nurse is caring for the client experiencing Guillain-Barre syndrome (GBS). It is most important for the nurse to monitor the client for which complication? 1. Autonomic dysreflexia 2. Septic emboli 3. Cardiac dysrhythmias 4. Respiratory failure

(4) Respiratory failure. Rationale: It is most important for the nurse to monitor for respiratory failure. Ascending paralysis that occurs for GBS can affect the innervation of the muscles used for respiration, leading to respiratory failure.

The home health nurse evaluates the foot care of the dark skinned African client who has peripheral neuropathy? Which client actions in providing foot care are appropriate? select all that apply. 1. Uses a mirror and visually inspects the foot on a daily basis. 2. Lotions the feet and legs daily, avoiding between the toes 3. Goes barefoot when indoors to help dry and air out the feet 4. Wears warm socks and boots when outside in cold weather. 5. Trims toenails weekly so they have a rounded contour 6. Inspects the feet for redness and other signs of inflammation

1. Uses a mirror and visually inspects the foot on a daily basis. 2. Lotions the feet and legs daily, avoiding between the toes 4. Wears warm socks and boots when outside in cold weather. Rationale: (1) Using a mirror allows for visual inspection of the bottom of the feet and between the toes for areas of breakdown (2) Keeping the skin adequately lubricated with lotion prevents drying and cracking. Lotion should not be applied between the toes because it increases moisture and the risk for infection. (4) Wearing appropriate clothing protects the skin from injury because sensation is diminished with peripheral neuropathy.

The female client with an incomplete T6 spinal cord transection asks the nurse for sexual health advice and the possibility of ever conceiving. Which statements by the nurse will be helpful to the client? Select all that apply. 1. "you need to continue to use contraceptives if you do not wish to have children." 2. "Unfortunately, your injury prevents you from being able to conceive children." 3. "Because feeling is affected, it is not likely that you will be able to deliver a baby." 4. "sexual intercourse is generally prohibited because it can worsen your condition." 5. "you can engage in sexual intimacy, but you may not be able to feel an orgasm."

1. You need to continue to use contraceptives if you do not wish to have children. 5. You can engage in sexual intimacy, but you may not be able to feel an orgasm. Rationale: (1) Although the client has an incomplete T6 SCI, the woman is still capable of becoming pregnant. (5) The client may not be able to feel an orgasm after an incomplete T6 SCI

The tonic in tonic-clonic seizures lasts for this long

The nurse is monitoring clients for development of a brain abscess. Which client would be the nurse's lowest priority for monitoring for a brain abscess? 1. Client with endocarditis 2. Client with idiopathic epilepsy 3. Client who had a liver transplant 4. Client with meningitis

2. A client with idiopathic epilepsy Rationale. This is the most appropriate response because it focuses on the client's concern, encourages verbalization, and solicits more information.

The nurse is caring for the client who has limited intake due to dysphagia following an ischemic stroke. Which serum laboratory result should the nurse review to verify that the client is dehydrated? 1. Elevated serum creatinine 2. Elevated blood urea nitrogen 3. Decreased hemoglobin 4. Decreased prealbumin

2. Elevated blood urea nitrogen Rationale: The BUN is elevated when the client is dehydrated due to the lack of fluid volume to excrete was products.

The client is in status epilepticus. Which interventions, if prescribed, should be included in this client's immediate treatment? Select all that apply? 1. Administer dexamethasone intravenuously 2. Give oxygen and prepare for endotracheal intubations. 3. Obtain a defibrillator and prepare its use immediately 4. Remove nearby objects to protect the client from injury 5. Administer lorazepam intravenously STAT.

2. Give oxygen and prepare for endotracheal intubation 4. Remove nearby objects to protect the client from injury 5. Administer lorazepam intravenously STAT Rationale: (2) Status epilepticus is a medical emergency. The client is at risk for brain hypoxia and permanent brain damage. The client needs additional oxygen, and intubation will secure the airway (4) Care is taken to protect the client from injury during the seizure (5) Either lorazepam (ativan) or diazepam (valium) is administered initially to terminate the seizure because they can be administered more rapidly than phenytoin.

The client, diagnosed with an ischemic stroke, is being evaluated for thrombolytic therapy. Which assessment finding should prompt the nurse to withhold thrombolytic therapy? 1. Brain CT scan results show no bleeding 2. Had a serious head injury four weeks ago 3. Has a history of type 1 diabetes mellitus 4. Neurological deficits started 2 hours ago

2. Had a serious head injury four weeks ago Contra/complications to thrombolytic therapy for the client with an ischemic stroke include a serious head injury within the previous 1 months. This would put the client at risk of developing serious bleeding problems specifically cerebral hemorrhage.

The home care nurse is counseling the client who has MS. The client is e experiencing weakness, ataxia, intermittent adductor spasms of the hips and occasional incontineance from loss of bladder sensation. Which self-care measures should the nurse recommend? select all that apply. 1. "Adductor spasms can be relieved by taking a hot bath." 2. "If a muscle is in spasm, stretch and hold it and then relax." 3. "Rest first and then walk as able using a walker for support." 4. "When walking, eep feet close together, legs slightly bent." 5. "Set an alarm to remind you to void 30 minutes after fluid intake."

2. If a muscle is in spasm, stretch and hold it and then relax 3. Rest first and then walk as able using a walker for support." 5. "Set an alarm to remind you to void 30 minutes after fluid intake." Rationale: (2) A stretch-hold-relax is often helpful for relaxing the muscle and treating muscle spasm (3) Walking will help improve the gait, strengthen weakened muscles, and help relieve spasticity in the legs. If a muscle group is irreversible by affected by MS other muscles can learn to compensate. A walker should be used for safety to help prevent falling. (5) Drinking fluids and then using an alarm to void 30 minutes later may be helful in reducing incontinence from loss of bladder sensation.

The client who has Type I DM, is scheduled for an MRI of the brain after an MVA. Which intervention should the nurse implement to prepare the client for the test? 1. Make the client NPO for six hours before the MRI and hold the morning insulin dose. 2. Inform the client that the machine is noisy and that earplugs can be worn during the test. 3. Explain that the extremity used for injection must remain straight for a few hours after MRI 4. Ensure that the serum BUN and creatinine levels are obtained and evaluated prior to the MRI

2. Inform the client that the machine is noisy and that earplugs can be worn during the test. Rationale: Clients are given earplugs to wear while undergoing the test because the machine makes a loud clanging noise that is unpleasant.

The nurse is caring for the older adult client with normal pressure hydrocephalus (NPH). Which treatment measure should the nurse anticipate? 1. Carotid endarterectomy 2. Ventriculoperitoneal shunt 3. Insertion of a lumbar drain 4. Anticonvulsant medications

2. Ventriculoperitoneal shunt Rationale: NPH is treated with the placement of a permanent shunt in a lateral ventricle of the brain to the peritoneal cavity. The excess CSF drains into the peritoneal cavity.

The client underwent a lumbar laminectomy with spinal fusion 12 hours earlier. Which nursing assessment finding indicates that the client has a leakage of CSF? 1. Backache not relieved by narcotic analgesic 2. 50 mL of serosanguineous fluid in the bulb drain 3. Clear fluid drainage noted on the surgical dressing 4. Sudden spike in temperature to 101.3 F (38.3C)

3. Clear fluid drainage noted on the surgical dressing Rationale: clear drainage on the surgical dressing is indicative of CSF leak.

The client, who had a stroke, follows the nurse's instructions without problems, but an attempt to verbally respond to the nurse's question was garbled. The nurse should identify that the client has which type of aphasia? 1. Receptive aphasia 2. Global aphasia 3. Expressive aphasia 4. Anomic aphasia

3. Expressive aphasia Rationale: The nurse should identify that the client has expressive aphasia (Broca's aphasia or non-fluent aphasia). The client is able to comprehend and responds appropriately. The client may attempt to speak but has difficulty communicating with the correct words.

The nurse is caring for the client who, 6 weeks after an MVA, was diagnosed with a mild TBI. Which information in the client's history of the injury should the nurse associate with the TBI? Select all that apply. 1. The client has had no episodes of vomiting after the accident 2. The client remembers events before and right after the accident 3. The client has had headache and dizziness daily since the accident. 4. The client has difficulty concentrating and focusing while at work. 5. The client lost consciousness momentarily at the time of the injury.

3. The client has had headache and dizziness daily since the accident. 4. The client has difficulty concentrating and focusing while at work. 5. The client lost consciousness momentarily at the time of the injury. Rationale: (3) Recurrent problems with headache and dizziness are the most prominent symptoms of mild TBI. (4) Cognitive difficulties including inability to concentrate and forgetfulness, occur with mild TBI. (5) At the time of the accident, the person with mild TBI may experience a loss of consciousness for a few seconds or minutes

The nurse is caring for the client who is having difficulty walking. Which procedure should the nurse perform to test the cerebellar function of the client? 1. With the client's eyes shut, ask whether the touch with a cotton applicator is sharp or dull. 2. Ask the client to close the eyes, then hold hands with palms up perpendicular to the body. 3. Ask the client to grasp and squeeze, with each hand at the same time, the hands of the nurse. 4. Have the client place the hands on the thighs, then quickly turn the palms up and then down. (REPETITIVE-TEST COORDINATION).

4. Have the client place the hands on the things, then quickly turn the palms up and then down.

The client who has a deteriorating status after having a stroke, has a rectal temperature of 102.3 F. Which should be the nurse's rationale for initiating interventions to bring the temperature to a normal level: 1. A normal temperature will strengthen the client's immune system 2. A hypothermic state may increase the client's chance of survival 3. A normal temperature will decrease the Glasgow Coma Scale score 4. Hyperthermia increases the likelihood of a larger area of brain infarct.

4. Hyperthermia increases the likelihood of a larger area of brain infarct. Rationale: The nurse should initiate temperature reduction measures because a temperature elevation in the client post stroke can cause an increase in the infarct size. This may be due to the increased oxygen demand with hyperthermia and peripheral vasodilation that decreases cerebral perfusion.
