Nursing 1 Final Exam

The nurse assesses clients for the cardinal signs of inflammation. Which signs/symptoms does this include? (Select all that apply.) a. Edema b. Pulselessness c. Pallor d. Redness e. Warmth

S: A, D, E The five cardinal signs of inflammation include redness, warmth, pain, swelling, and decreased function.

A client had proxymetacaine (Ocu-Caine) instilled in one eye in the emergency department. What discharge instruction is most important? a. Do not touch or rub the eye until it is no longer numb. b. Monitor the eye for any bleeding for the next day. c. Rinse the eye with warm saline solution at home. d. Use all the eyedrops as prescribed until they are gone.

ANS: A This drug is an ophthalmic anesthetic. The client can injure the numb eye by touching or rubbing it. Bleeding is not associated with this drug. The client should not be told to rinse the eye. This medication was given in the emergency department and is not prescribed for home use.

The nurse enters an examination room to help with an eye examination. The client is directed toward the assessment chart shown below: What is the provider assessing? a. Color vision b. Depth perception c. Spatial perception d. Visual acuity

ANS: A This is an Ishihara chart, which is used for assessing color vision. Depth and spatial perception are not typically assessed in a routine vision assessment. Visual acuity is usually tested with a Snellen chart.

A client has a foreign body in the eye. What action by the nurse takes priority? a. Administering ordered antibiotics b. Assessing the client's visual acuity c. Obtaining consent for enucleation d. Removing the object immediately

ANS: A To prevent infection, antibiotics are provided. Visual acuity in the affected eye cannot be assessed. The client may or may not need enucleation. The object is only removed by the ophthalmologist.

A nurse has delegated applying a warm compress to a client's eye. What actions by the unlicensed assistive personnel (UAP) warrant intervention by the nurse? (Select all that apply.) a. Heating the wet washcloth in the microwave b. Holding the cloth on the client using an Ace wrap c. Turning the cloth so it remains warm on the client d. Using a clean washcloth for the compress e. Washing the hands on entering the client's room

ANS: A, B The washcloth should be warmed under running warm water. Microwaving it can lead to burns. Gentle pressure is used to hold the compress in place. The other actions are correct.

A nurse is admitting an older client for surgery to the inpatient surgical unit. The client relates a prior history of acute confusion after a previous operation. What interventions does the nurse include on the client's plan of care to minimize the potential for this occurring? (Select all that apply.) a. Allow family and friends to visit as the client desires. b. Ask the client about coping techniques frequently used. c. Instruct the nursing assistant to ensure the client is bathed. d. Place the client in a room secluded at the end of the hall. e. Provide the client with uninterrupted periods of sleep.

ANS: A, B, C, E Older clients may have difficulty adjusting to the stress of the hospital environment and illness or surgery. Techniques that are helpful include allowing liberal visitation, assisting the client to use successful coping techniques, and keeping the client bathed and groomed. Sleep deprivation can contribute to confusion, so the nurse ensures the client receives adequate sleep. Secluding the client at the end of the hall may lead to sensory deprivation and loneliness.

A nurse is teaching a client with diabetes mellitus who asks, "Why is it necessary to maintain my blood glucose levels no lower than about 60 mg/dL?" How should the nurse respond? a. "Glucose is the only fuel used by the body to produce the energy that it needs." b. "Your brain needs a constant supply of glucose because it cannot store it." c. "Without a minimum level of glucose, your body does not make red blood cells." d. "Glucose in the blood prevents the formation of lactic acid and prevents acidosis."

ANS: B Because the brain cannot synthesize or store significant amounts of glucose, a continuous supply from the body's circulation is needed to meet the fuel demands of the central nervous system. The nurse would want to educate the client to prevent hypoglycemia. The body can use other sources of fuel, including fat and protein, and glucose is not involved in the production of red blood cells. Glucose in the blood will encourage glucose metabolism but is not directly responsible for lactic acid formation.

A nurse is seeing clients in the ophthalmology clinic. Which client should the nurse see first? a. Client with intraocular pressure reading of 24 mm Hg b. Client who has had cataract surgery and has worsening vision c. Client whose red reflex is absent on ophthalmologic examination d. Client with a tearing, reddened eye with exudate

ANS: B After cataract surgery, worsening vision indicates an infection or other complication. The nurse should see this client first. The intraocular pressure is slightly elevated. An absent red reflex may indicate cataracts. The client who has the tearing eye may have an infection.

A client has been prescribed brinzolamide (Azopt). What assessment by the nurse requires consultation with the provider? a. Allergy to eggs b. Allergy to sulfonamides c. Use of contact lenses d. Use of beta blockers

ANS: B Brinzolamide is similar to sulfonamides, so an allergic reaction could occur. The other assessment findings are not related to brinzolamide.

A postanesthesia care unit (PACU) nurse is assessing a postoperative client with a nasogastric (NG) tube. What laboratory values would warrant intervention by the nurse? (Select all that apply.) a. Blood glucose: 120 mg/dL b. Hemoglobin: 7.8 mg/dL c. pH: 7.68 d. Potassium: 2.9 mEq/L e. Sodium: 142 mEq/L

ANS: B, C, D Fluid and electrolyte balance are assessed carefully in the postoperative client because many imbalances can occur. The low hemoglobin may be from blood loss in surgery. The higher pH level indicates alkalosis, possibly from losses through the NG tube. The potassium is very low. The blood glucose is within normal limits for a postsurgical client who has been fasting. The sodium level is normal.

A student nurse is learning about the types of different cells involved in the inflammatory response. Which principles does the student learn? (Select all that apply.) a. Basophils are only involved in the general inflammatory process. b. Eosinophils increase during allergic reactions and parasitic invasion. c. Macrophages can participate in many episodes of phagocytosis. d. Monocytes turn into macrophages after they enter body tissues. e. Neutrophils can only take part in one episode of phagocytosis.

ANS: B, C, D, E Eosinophils do increase during allergic and parasitic invasion. Macrophages participate in many episodes of phagocytosis. Monocytes turn into macrophages after they enter body tissues. Neutrophils only take part in one episode of phagocytosis. Basophils are involved in both the general inflammatory response and allergic or hypersensitivity responses.

A nurse on the postoperative nursing unit provides care to reduce the incidence of surgical wound infection. What actions are best to achieve this goal? (Select all that apply.) a. Administering antibiotics for 72 hours b. Disposing of dressings properly c. Leaving draining wounds open to air d. Performing proper hand hygiene e. Removing and replacing wet dressings

ANS: B, D, E Interventions necessary to prevent surgical wound infection include proper disposal of soiled dressings, performing proper hand hygiene, and removing wet dressings as they can be a source of infection. Prophylactic antibiotics are given to clients at risk for infection, but are discontinued after 24 hours if no infection is apparent. Draining wounds should always be covered.

1. A nurse orienting to the postoperative area learns which principles about the postoperative period? (Select all that apply.) a. All phases require the client to be in the hospital. b. Phase I care may last for several days in some clients. c. Phase I requires intensive care unit monitoring. d. Phase II ends when the client is stable and awake. e. Vital signs may be taken only once a day in phase III.

ANS: B, D, E There are three phases of postoperative care. Phase I is the most intense, with clients coming right from surgery until they are completely awake and hemodynamically stable. This may take hours or days and can occur in the intensive care unit or the postoperative care unit. Phase II ends when the client is at a presurgical level of consciousness and baseline oxygen saturation, and vital signs are stable. Phase III involves the extended care environment and may continue at home or in an extended care facility if needed.

A client had a surgical procedure with spinal anesthesia. The nurse raises the head of the client's bed. The client's blood pressure changes from 122/78 mm Hg to 102/50 mm Hg. What action by the nurse is best? a. Call the Rapid Response Team. b. Increase the IV fluid rate. c. Lower the head of the bed. d. Nothing; this is expected.

ANS: C A client who had epidural or spinal anesthesia may become hypotensive when the head of the bed is raised. If this occurs, the nurse should lower the head of the bed to its original position. The Rapid Response Team is not needed, nor is an increase in IV rate.

A client is seen in the ophthalmology clinic with bacterial conjunctivitis. Which statements by the client indicate a good understanding of home management of this condition? (Select all that apply.) a. "As long as I don't wipe my eyes, I can share my towel." b. "Eye irrigations should be done with warm saline or water." c. "I will throw away all my eye makeup when I get home." d. "I won't touch the tip of the eyedrop bottle to my eye." e. "When the infection is gone, I can use my contacts again."

ANS: C, D Bacterial conjunctivitis is very contagious, and re-infection or cross-contamination between the client's eyes is possible. The client should discard all eye makeup being used at the time the infection started. When instilling eyedrops, the client must be careful not to contaminate the bottle by touching the tip to the eye or face. The client should be instructed not to share towels. Eye irrigations are not needed. Contacts being used when the infection first manifests also need to be discarded.

Ten hours after surgery, a postoperative client reports that the antiembolism stockings and sequential compression devices itch and are too hot. The client asks the nurse to remove them. What response by the nurse is best? a. "Let me call the surgeon to see if you really need them." b. "No, you have to use those for 24 hours after surgery." c. "OK, we can remove them since you are stable now." d. "To prevent blood clots you need them a few more hours."

ANS: D According to the Surgical Care Improvement Project (SCIP), any prophylactic measures to prevent thromboembolic events during surgery are continued for 24 hours afterward. The nurse should explain this to the client. Calling the surgeon is not warranted. Simply telling the client he or she has to wear the hose and compression devices does not educate the client. The nurse should not remove the devices.

A nurse assesses clients who are at risk for diabetes mellitus. Which client is at greatest risk? a. A 29-year-old Caucasian b. A 32-year-old African-American c. A 44-year-old Asian d. A 48-year-old American Indian

ANS: D Diabetes is a particular problem among African Americans, Hispanics, and American Indians. The incidence of diabetes increases in all races and ethnic groups with age. Being both an American Indian and middle-aged places this client at highest risk.

After teaching a client with type 2 diabetes mellitus who is prescribed nateglinide (Starlix), the nurse assesses the client's understanding. Which statement made by the client indicates a correct understanding of the prescribed therapy? a. "I'll take this medicine during each of my meals." b. "I must take this medicine in the morning when I wake." c. "I will take this medicine before I go to bed." d. "I will take this medicine immediately before I eat."

ANS: D Nateglinide is an insulin secretagogue that is designed to increase meal-related insulin secretion. It should be taken immediately before each meal. The medication should not be taken without eating as it will decrease the client's blood glucose levels. The medication should be taken before meals instead of during meals.

8. The nurse working with clients who have autoimmune diseases understands that what component of cell-mediated immunity is the problem? a. CD4+ cells b. Cytotoxic T cells c. Natural killer cells d. Suppressor T cells

ANS: D Suppressor T cells help prevent hypersensitivity to one's own cells, which is the basis for autoimmune disease. CD4+ cells are also known as helper/inducer cells, which secrete cytokines. Natural killer cells have direct cytotoxic effects on some non-self cells without first being sensitized. Suppressor T cells have an inhibitory action on the immune system. Cytotoxic T cells are effective against self cells infected by parasites such as viruses or protozoa.

A client is taking timolol (Timoptic) eyedrops. The nurse assesses the client's pulse at 48 beats/min. What action by the nurse is the priority? a. Ask the client about excessive salivation. b. Assess the client for shortness of breath. c. Give the drops using punctal occlusion. d. Hold the eyedrops and notify the provider.

ANS: D The nurse should hold the eyedrops and notify the provider because beta blockers can slow the heart rate. Excessive salivation can occur with cholinergic agonists. Shortness of breath is not related. If the drops are given, the nurse uses punctal occlusion to avoid systemic absorption.

A client has been taught about retinitis pigmentosa (RP). What statement by the client indicates a need for further teaching? a. "Beta carotene, lutein, and zeaxanthin are good supplements." b. "I might qualify for a retinal transplant one day soon." c. "Since I'm going blind, sunglasses are not needed anymore." d. "Vitamin A has been shown to slow progression of RP."

ANS: C Sunglasses are needed to prevent the development of cataracts in addition to the RP. The other statements are accurate.

A client had a retinal detachment and has undergone surgical correction. What discharge instruction is most important? a. "Avoid reading, writing, or close work such as sewing." b. "Dim the lights in your house for at least a week." c. "Keep the follow-up appointment with the ophthalmologist." d. "Remove your eye patch every hour for eyedrops."

ANS: A After surgery for retinal detachment, the client is advised to avoid reading, writing, and close work because they cause rapid eye movements. Dim lights are not indicated. Keeping a postoperative appointment is important for any surgical client. The eye patch is not removed for eyedrops.

A client's chart indicates anisocoria. For what should the nurse assess? a. Difference in pupil size b. Draining infection c. Recent eye trauma d. Tumor of the eyelid

ANS: A Anisocoria is a noticeable difference in the size of a person's pupils. This is a normal finding in a small percentage of the population. Infection, trauma, and tumors are not related.

A client has a corneal ulcer. What information provided by the client most indicates a potential barrier to home care? a. Chronic use of sleeping pills b. Impaired near vision c. Slightly shaking hands d. Use of contact lenses

ANS: A Antibiotic eyedrops are often needed every hour for the first 24 hours for corneal ulceration. The client who uses sleeping pills may not wake up each hour or may awaken unable to perform this task. This client might need someone else to instill the eyedrops hourly. Impaired near vision and shaking hands can both make administration of eyedrops more difficult but are not the most likely barriers. Contact lenses should be discarded.

A postoperative client has just been admitted to the postanesthesia care unit (PACU). What assessment by the PACU nurse takes priority? a. Airway b. Bleeding c. Breathing d. Cardiac rhythm

ANS: A Assessing the airway always takes priority, followed by breathing and circulation. Bleeding is part of the circulation assessment, as is cardiac rhythm.

2. A nurse is assessing an older client for the presence of infection. The client's temperature is 97.6° F (36.4° C). What response by the nurse is best? a. Assess the client for more specific signs. b. Conclude that an infection is not present. c. Document findings and continue to monitor. d. Request that the provider order blood cultures.

ANS: A Because older adults have decreased immune function, including reduced neutrophil function, fever may not be present during an episode of infection. The nurse should assess the client for specific signs of infection. Documentation needs to occur, but a more thorough assessment comes first. Blood cultures may or may not be needed depending on the results of further assessment.

The nurse has given a community group a presentation on eye health. Which statement by a participant indicates a need for more instruction? a. "I always lose my sunglasses, so I don't wear them." b. "I have diabetes and get an annual eye exam." c. "I will not share my contact solution with others." d. "I will wear safety glasses when I mow the lawn."

ANS: A Clients should be taught to protect their eyes from ultraviolet (UV) exposure by consistently wearing sunglasses when outdoors, when tanning in tanning salons, or when working with UV light. The other statements are correct.

A client presents to the emergency department reporting a foreign body in the eye. For what diagnostic testing should the nurse prepare the client? a. Corneal staining b. Fluorescein angiography c. Ophthalmoscopy d. Tonometry

ANS: A Corneal staining is used when the possibility of eye trauma exists, including a foreign body. Fluorescein angiography is used to assess problems of retinal circulation. Ophthalmoscopy looks at both internal and external eye structures. Tonometry tests the intraocular pressure.

The nurse reads on a client's chart that the client has exophthalmos. What assessment finding is consistent with this diagnosis? a. Bulging eyes b. Drooping eyelids c. Sunken-in eyes d. Yellow sclera

ANS: A Exophthalmos is bulging eyes. Drooping eyelids is ptosis. Sunken-in eyes is enophthalmos. Yellow sclera indicates jaundice.

A postoperative client has respiratory depression after receiving midazolam (Versed) for sedation. Which IV-push medication and dose does the nurse prepare to administer? a. Flumazenil (Romazicon) 0.2 to 1 mg b. Flumazenil (Romazicon) 2 to 10 mg c. Naloxone (Narcan) 0.4 to 2 mg d. Naloxone (Narcan) 4 to 20 mg

ANS: A Flumazenil is a benzodiazepine antagonist and would be the correct drug to use in this situation. The correct dose is 0.2 to 1 mg. Naloxone is an opioid antagonist.

A client does not understand why vision loss due to glaucoma is irreversible. What explanation by the nurse is best? a. "Because eye pressure was too high, the tissue died." b. "Glaucoma always leads to permanent blindness." c. "The traumatic damage to your eye was too great." d. "The infection occurs so quickly it can't be treated."

ANS: A Glaucoma is caused when the intraocular pressure becomes too high and stays high long enough to cause tissue ischemia and death. At that point, vision loss is permanent. Glaucoma does not have to cause blindness. Trauma can cause glaucoma but is not the most common cause. Glaucoma is not an infection.

A client has been on dialysis for many years and now is receiving a kidney transplant. The client experiences hyperacute rejection. What treatment does the nurse prepare to facilitate? a. Dialysis b. High-dose steroid administration c. Monoclonal antibody therapy d. Plasmapheresis

ANS: A Hyperacute rejection starts within minutes of transplantation and nothing will stop the process. The organ is removed. If the client survives, he or she will have to return to dialysis treatment. Steroids, monoclonal antibodies, and plasmapheresis are ineffective against this type of rejection.

A nurse teaches a client who is diagnosed with diabetes mellitus. Which statement should the nurse include in this client's plan of care to delay the onset of microvascular and macrovascular complications? a. "Maintain tight glycemic control and prevent hyperglycemia." b. "Restrict your fluid intake to no more than 2 liters a day." c. "Prevent hypoglycemia by eating a bedtime snack." d. "Limit your intake of protein to prevent ketoacidosis."

ANS: A Hyperglycemia is a critical factor in the pathogenesis of long-term diabetic complications. Maintaining tight glycemic control will help delay the onset of complications. Restricting fluid intake is not part of the treatment plan for clients with diabetes. Preventing hypoglycemia and ketosis, although important, are not as important as maintaining daily glycemic control.

A postoperative nurse is caring for a client whose oxygen saturation dropped from 98% to 95%. What action by the nurse is most appropriate? a. Assess other indicators of oxygenation. b. Call the Rapid Response Team. c. Notify the anesthesia provider. d. Prepare to intubate the client.

ANS: A If a postoperative client's oxygen saturation (SaO2) drops below 95% (or the client's baseline), the nurse should notify the anesthesia provider. If the SaO2 drops by 10% or more, the nurse should call the Rapid Response Team. Since this is approximately a 3% drop, the nurse should further assess the client. Intubation (if the client is not intubated already) is not warranted.

A nurse cares for a client with diabetes mellitus who is visually impaired. The client asks, "Can I ask my niece to prefill my syringes and then store them for later use when I need them?" How should the nurse respond? a. "Yes. Prefilled syringes can be stored for 3 weeks in the refrigerator in a vertical position with the needle pointing up." b. "Yes. Syringes can be filled with insulin and stored for a month in a location that is protected from light." c. "Insulin reacts with plastic, so prefilled syringes are okay, but you will need to use glass syringes." d. "No. Insulin syringes cannot be prefilled and stored for any length of time outside of the container."

ANS: A Insulin is relatively stable when stored in a cool, dry place away from light. When refrigerated, prefilled plastic syringes are stable for up to 3 weeks. They should be stored in the refrigerator in the vertical position with the needle pointing up to prevent suspended insulin particles from clogging the needle.

A client receiving muromonab-CD3 (Orthoclone OKT3) asks the nurse how the drug works. What response by the nurse is best? a. "It increases the elimination of T lymphocytes from circulation." b. "It inhibits cytokine production in most lymphocytes." c. "It prevents DNA synthesis, stopping cell division in activated lymphocytes." d. "It prevents the activation of the lymphocytes responsible for rejection."

ANS: A Muromonab-CD3 (Orthoclone OKT3) is a monoclonal antibody that works to increase the elimination of T lymphocytes from circulation. The corticosteroids broadly inhibit cytokine production in most leukocytes, resulting in generalized immunosuppression. The main action of all antiproliferatives (such as azathioprine [Imuran]) is to inhibit something essential to DNA synthesis, which prevents cell division in activated lymphocytes. Calcineurin inhibitors such as cyclosporine (Sandimmune) stop the production and secretion of interleukin-2, which then prevents the activation of lymphocytes involved in transplant rejection.

A clinic nurse is working with an older client. What assessment is most important for preventing infections in this client? a. Assessing vaccination records for booster shot needs b. Encouraging the client to eat a nutritious diet c. Instructing the client to wash minor wounds carefully d. Teaching hand hygiene to prevent the spread of microbes

ANS: A Older adults may have insufficient antibodies that have already been produced against microbes to which they have been exposed. Therefore, older adults need booster shots for many vaccinations they received as younger people. A nutritious diet, proper wound care, and hand hygiene are relevant for all populations.

A client is taking prednisone to prevent transplant rejection. What instruction by the nurse is most important? a. "Avoid large crowds and people who are ill." b. "Check over-the-counter meds for acetaminophen." c. "Take this medicine exactly as prescribed." d. "You have a higher risk of developing cancer."

ANS: A Prednisone, like all steroids, decreases immune function. The client should be advised to avoid large crowds and people who are ill. Prednisone does not contain acetaminophen. All clients should be taught to take medications exactly as prescribed. A higher risk for cancer is seen with drugs from the calcineurin inhibitor category, such as tacrolimus (Prograf).

A nurse cares for a client who has a family history of diabetes mellitus. The client states, "My father has type 1 diabetes mellitus. Will I develop this disease as well?" How should the nurse respond? a. "Your risk of diabetes is higher than the general population, but it may not occur." b. "No genetic risk is associated with the development of type 1 diabetes mellitus." c. "The risk for becoming a diabetic is 50% because of how it is inherited." d. "Female children do not inherit diabetes mellitus, but male children will."

ANS: A Risk for type 1 diabetes is determined by inheritance of genes coding for HLA-DR and HLA-DQ tissue types. Clients who have one parent with type 1 diabetes are at increased risk for its development. Diabetes (type 1) seems to require interaction between inherited risk and environmental factors, so not everyone with these genes develops diabetes. The other statements are not accurate.

A nursing student learning about antibody-mediated immunity learns that the cell with the most direct role in this process begins development in which tissue or organ? a. Bone marrow b. Spleen c. Thymus d. Tonsils

ANS: A The B cell is the primary cell in antibody-mediated immunity and is released from the bone marrow. These cells then travel to other organs and tissues, known as the secondary lymphoid tissues for B cells.

After teaching a client with diabetes mellitus to inject insulin, the nurse assesses the client's understanding. Which statement made by the client indicates a need for additional teaching? a. "The lower abdomen is the best location because it is closest to the pancreas." b. "I can reach my thigh the best, so I will use the different areas of my thighs." c. "By rotating the sites in one area, my chance of having a reaction is decreased." d. "Changing injection sites from the thigh to the arm will change absorption rates."

ANS: A The abdominal site has the fastest rate of absorption because of blood vessels in the area, not because of its proximity to the pancreas. The other statements are accurate assessments of insulin administration.

A nurse assesses a client with diabetes mellitus and notes the client only responds to a sternal rub by moaning, has capillary blood glucose of 33 g/dL, and has an intravenous line that is infiltrated with 0.45% normal saline. Which action should the nurse take first? a. Administer 1 mg of intramuscular glucagon. b. Encourage the client to drink orange juice. c. Insert a new intravenous access line. d. Administer 25 mL dextrose 50% (D50) IV push.

ANS: A The client's blood glucose level is dangerously low. The nurse needs to administer glucagon IM immediately to increase the client's blood glucose level. The nurse should insert a new IV after administering the glucagon and can use the new IV site for future doses of D50 if the client's blood glucose level does not rise. Once the client is awake, orange juice may be administered orally along with a form of protein such as a peanut butter.

The nursing student studying the eye learns that which cranial nerves control its functions? (Select all that apply.) a. II b. III c. VI d. XII e. X

ANS: A, B, C The cranial nerves involved with eye function include II, III, IV, V, VI, and VII.

For a person to be immunocompetent, which processes need to be functional and interact appropriately with each other? (Select all that apply.) a. Antibody-mediated immunity b. Cell-mediated immunity c. Inflammation d. Red blood cells e. White blood cells

ANS: A, B, C The three processes that need to be functional and interact with each other for a person to be immunocompetent are antibody-mediated immunity, cell-mediated immunity, and inflammation. Red and white blood cells are not processes.

5. A client is experiencing pain after leg surgery but cannot yet have more pain medication. What comfort interventions can the nurse provide? (Select all that apply.) a. Apply stimulation to the contralateral leg. b. Assess the client's willingness to try meditation. c. Elevate the client's operative leg and apply ice. d. Reduce the noise level in the client's environment. e. Turn the TV on loudly to distract the client.

ANS: A, B, C, D There are many nonpharmacologic comfort measures for pain, including applying stimulation to the opposite leg, providing opportunities for meditation, elevation of the leg, applying ice, and reducing noxious stimuli in the environment. Participating in diversional activities is another approach, but simply turning the TV on loudly does not provide a good diversion.

A postoperative client is being discharged with a prescription for oxycodone hydrochloride with acetaminophen (Percocet). What instructions does the nurse give the client? (Select all that apply.) a. "Check all over-the-counter medications for acetaminophen." b. "Do not take more pills each day than you are prescribed." c. "Eat a diet that is high in fiber and drink lots of water." d. "If this gives you diarrhea, loperamide (Imodium) can help." e. "You shouldn't drive while you are taking this medication."

ANS: A, B, C, E Percocet is a common opioid analgesic that contains acetaminophen. The client should be taught to check all over-the-counter medications for acetaminophen and to not take more than the prescribed amount of Percocet, as the maximum daily dose of acetaminophen is 3000 mg. Percocet, like all opioid analgesics, can cause constipation, and the client can minimize this by eating a high-fiber diet and drinking plenty of water. Since Percocet can cause drowsiness, the client taking it should not drive or operate machinery. The medication is more likely to cause constipation than diarrhea.

A client had cataract surgery. What instructions should the nurse provide? (Select all that apply.) a. Call the doctor for increased pain. b. Do not bend over from the waist. c. Do not lift more than 10 pounds. d. Sexual intercourse is allowed. e. Use stool softeners to avoid constipation.

ANS: A, B, C, E The client should be taught to call the physician for increased pain as this might indicate infection or other complication. To avoid increasing intraocular pressure, clients are taught to not lift more than 10 pounds, to avoid bending at the waist, to avoid straining at stool, and to avoid sexual intercourse for a time after surgery.

The nursing student learns that age-related changes affect the eyes and vision. Which changes does this include? (Select all that apply.) a. Decreased eye muscle tone b. Development of arcus senilis c. Increase in far point of near vision d. Decrease in general color perception e. Increase in point of near vision

ANS: A, B, D, E Normal age-related changes include decreased eye muscle tone, development of arcus senilis, decreased color perception, and increased point of near vision. The far point of near vision typically decreases.

Which are steps in the process of making an antigen-specific antibody? (Select all that apply.) a. Antibody-antigen binding b. Invasion c. Opsonization d. Recognition e. Sensitization

ANS: A, B, D, E The seven steps in the process of making antigen-specific antibodies are: exposure/invasion, antigen recognition, sensitization, antibody production and release, antigen-antibody binding, antibody binding actions, and sustained immunity. Opsonization is the adherence of an antibody to the antigen, marking it for destruction.

The student nurse is learning about the functions of different antibodies. Which principles does the student learn? (Select all that apply.) a. IgA is found in high concentrations in secretions from mucous membranes. b. IgD is present in the highest concentrations in mucous membranes. c. IgE is associated with antibody-mediated hypersensitivity reactions. d. IgG comprises the majority of the circulating antibody population. e. IgM is the first antibody formed by a newly sensitized B cell.

ANS: A, C, D, E Immunoglobulin A (IgA) is found in high concentrations in secretions from mucous membranes. Immunoglobulin E (IgE) is associated with antibody-mediated hypersensitivity reactions. The majority of the circulating antibody population consists of immunoglobulin G (IgG). The first antibody formed by a newly sensitized B cell is immunoglobulin M (IgM). Immunoglobulin D (IgD) is typically present in low concentrations.

The student learning about vision should remember which facts related to the eyes? (Select all that apply.) a. Aqueous humor controls intraocular pressure. b. Cones work in low light conditions. c. Glaucoma occurs due to increased pressure in the eye. d. Muscles of the iris control light entering the eye. e. Rods work in low light conditions.

ANS: A, C, D, E The inflow and outflow of aqueous humor controls the intraocular pressure. Glaucoma results when the pressure is chronically high. Muscles of the iris relax and constrict to control the amount of light entering the eye. Rods work in low light conditions. Cones work in bright light conditions.

A client is brought to the emergency department after a car crash. The client has a large piece of glass in the left eye. What action by the nurse takes priority? a. Administer a tetanus booster shot. b. Ensure the client has a patent airway. c. Prepare to irrigate the client's eye. d. Turn the client on the unaffected side.

ANS: B Airway always comes first. After ensuring a patent airway and providing cervical spine precautions (do not turn the client to the side), the nurse provides other care that may include administering a tetanus shot. The client's eye may or may not be irrigated.

5. A client has a leg wound that is in the second stage of the inflammatory response. For what manifestation does the nurse assess? a. Noticeable rubor b. Purulent drainage c. Swelling and pain d. Warmth at the site

ANS: B During the second phase of the inflammatory response, neutrophilia occurs, producing pus. Rubor (redness), swelling, pain, and warmth are cardinal signs of the general inflammatory process.

A nurse cares for a client with diabetes mellitus who asks, "Why do I need to administer more than one injection of insulin each day?" How should the nurse respond? a. "You need to start with multiple injections until you become more proficient at self-injection." b. "A single dose of insulin each day would not match your blood insulin levels and your food intake patterns." c. "A regimen of a single dose of insulin injected each day would require that you eat fewer carbohydrates." d. "A single dose of insulin would be too large to be absorbed, predictably putting you at risk for insulin shock."

ANS: B Even when a single injection of insulin contains a combined dose of different-acting insulin types, the timing of the actions and the timing of food intake may not match well enough to prevent wide variations in blood glucose levels. One dose of insulin would not be appropriate even if the client decreased carbohydrate intake. Additional injections are not required to allow the client practice with injections, nor will one dose increase the client's risk of insulin shock.

An older client has decided to give up driving due to cataracts. What assessment information is most important to collect? a. Family history of visual problems b. Feelings related to loss of driving c. Knowledge about surgical options d. Presence of family support

ANS: B Loss of driving is often associated with loss of independence, as is decreasing vision. The nurse should assess how the client feels about this decision and what its impact will be. Family history and knowledge about surgical options are not related as the client has made a decision to decline surgery. Family support is also useful information, but it is most important to get the client's perspective on this change.

A nurse teaches a client with type 2 diabetes mellitus who is prescribed glipizide (Glucotrol). Which statement should the nurse include in this client's teaching? a. "Change positions slowly when you get out of bed." b. "Avoid taking nonsteroidal anti-inflammatory drugs (NSAIDs)." c. "If you miss a dose of this drug, you can double the next dose." d. "Discontinue the medication if you develop a urinary infection."

ANS: B NSAIDs potentiate the hypoglycemic effects of sulfonylurea agents. Glipizide is a sulfonylurea. The other statements are not applicable to glipizide.

A nurse answers a call light on the postoperative nursing unit. The client states there was a sudden gush of blood from the incision, and the nurse sees a blood spot on the sheet. What action should the nurse take first? a. Assess the client's blood pressure. b. Perform hand hygiene and apply gloves. c. Reinforce the dressing with a clean one. d. Remove the dressing to assess the wound.

ANS: B Prior to assessing or treating the drainage from the wound, the nurse performs hand hygiene and dons gloves to protect both the client and nurse from infection.

A nurse is caring for a postoperative client who reports discomfort, but denies serious pain and does not want medication. What action by the nurse is best to promote comfort? a. Assess the client's pain on a 0-to-10 scale. b. Assist the client into a position of comfort. c. Have the client sit up in a recliner. d. Tell the client when pain medication is due.

ANS: B Several nonpharmacologic comfort measures can help postoperative clients with their pain, including distraction, music, massage, guided imagery, and positioning. The nurse should help this client into a position of comfort considering the surgical procedure and position of any tubes or drains. Assessing the client's pain is important but does not improve comfort. The client may be more uncomfortable in a recliner. Letting the client know when pain medication can be given next is important but does not improve comfort.

A nurse teaches a client about self-monitoring of blood glucose levels. Which statement should the nurse include in this client's teaching to prevent bloodborne infections? a. "Wash your hands after completing each test." b. "Do not share your monitoring equipment." c. "Blot excess blood from the strip with a cotton ball." d. "Use gloves when monitoring your blood glucose."

ANS: B Small particles of blood can adhere to the monitoring device, and infection can be transported from one user to another. Hepatitis B in particular can survive in a dried state for about a week. The client should be taught to avoid sharing any equipment, including the lancet holder. The client should be taught to wash his or her hands before testing. The client would not need to blot excess blood away from the strip or wear gloves.

The nurse is administering eyedrops to a client with an infection in the right eye. The drops go in both eyes, and two different bottles are used to administer the drops. The nurse accidentally uses the left eye bottle for the right eye. What action by the nurse is best? a. Inform the provider of the issue. b. Obtain a new bottle of eyedrops. c. Rinse the client's right eye thoroughly. d. Wipe the left eye bottle with alcohol.

ANS: B The nurse has contaminated the "clean" bottle by using it on the infected eye. The nurse needs to obtain a new bottle of solution to use on the left eye. The other actions are not appropriate.

The nurse working in an organ transplantation program knows that which individual is typically the best donor of an organ? a. Child b. Identical twin c. Parent d. Same-sex sibling

ANS: B The recipient's immune system recognizes donated tissues as non-self except in the case of an identical twin, whose genetic makeup is identical to the recipient.

A nurse cares for a client who is prescribed pioglitazone (Actos). After 6 months of therapy, the client reports that his urine has become darker since starting the medication. Which action should the nurse take? a. Assess for pain or burning with urination. b. Review the client's liver function study results. c. Instruct the client to increase water intake. d. Test a sample of urine for occult blood.

ANS: B Thiazolidinediones (including pioglitazone) can affect liver function; liver function should be assessed at the start of therapy and at regular intervals while the client continues to take these drugs. Dark urine is one indicator of liver impairment because bilirubin is increased in the blood and is excreted in the urine. The nurse should check the client's most recent liver function studies. The nurse does not need to assess for pain or burning with urination and does not need to check the urine for occult blood. The client does not need to be told to increase water intake.

A postoperative client vomited. After cleaning and comforting the client, which action by the nurse is most important? a. Allow the client to rest. b. Auscultate lung sounds. c. Document the episode. d. Encourage the client to eat dry toast.

ANS: B Vomiting after surgery has several complications, including aspiration. The nurse should listen to the client's lung sounds. The client should be allowed to rest after an assessment. Documenting is important, but the nurse needs to be able to document fully, including an assessment. The client should not eat until nausea has subsided.

1. The student nurse learns that the most important function of inflammation and immunity is which purpose? a. Destroying bacteria before damage occurs b. Preventing any entry of foreign material c. Providing protection against invading organisms d. Regulating the process of self-tolerance

ANS: C The purpose of inflammation and immunity is to provide protection to the body against invading organisms, whether they are bacterial, viral, protozoal, or fungal. These systems eliminate, destroy, or neutralize the offending agents. The cells of the immune system are the only cells that can distinguish self from non-self. This function is generalized and incorporates destroying bacteria, preventing entry of foreign invaders, and regulating self-tolerance.

A nurse is assessing a client for acute rejection of a kidney transplant. What assessment finding requires the most rapid communication with the provider? a. Blood urea nitrogen (BUN) of 18 mg/dL b. Cloudy, foul-smelling urine c. Creatinine of 3.9 mg/dL d. Urine output of 340 mL/8 hr

ANS: C A creatinine of 3.9 mg/dL is high, indicating possible dysfunction of the kidney. This is a possible sign of rejection. The BUN is normal, as is the urine output. Cloudy, foul-smelling urine would probably indicate a urinary tract infection.

A nurse assesses a client who has a 15-year history of diabetes and notes decreased tactile sensation in both feet. Which action should the nurse take first? a. Document the finding in the client's chart. b. Assess tactile sensation in the client's hands. c. Examine the client's feet for signs of injury. d. Notify the health care provider.

ANS: C Diabetic neuropathy is common when the disease is of long duration. The client is at great risk for injury in any area with decreased sensation because he or she is less able to feel injurious events. Feet are common locations for neuropathy and injury, so the nurse should inspect them for any signs of injury. After assessment, the nurse should document findings in the client's chart. Testing sensory perception in the hands may or may not be needed. The health care provider can be notified after assessment and documentation have been completed.

7. The nurse understands that which type of immunity is the longest acting? a. Artificial active b. Inflammatory c. Natural active d. Natural passive

ANS: C Natural active immunity is the most effective and longest acting type of immunity. Artificial and natural passive do not last as long. "Inflammatory" is not a type of immunity.

The postanesthesia care unit (PACU) charge nurse notes vital signs on four postoperative clients. Which client should the nurse assess first? a. Client with a blood pressure of 100/50 mm Hg b. Client with a pulse of 118 beats/min c. Client with a respiratory rate of 6 breaths/min d. Client with a temperature of 96° F (35.6° C)

ANS: C The respiratory rate is the most critical vital sign for any client who has undergone general anesthesia or moderate sedation, or has received opioid analgesia. This respiratory rate is too low and indicates respiratory depression. The nurse should assess this client first. A blood pressure of 100/50 mm Hg is slightly low and may be within that client's baseline. A pulse of 118 beats/min is slightly fast, which could be due to several causes, including pain and anxiety. A temperature of 96° F is slightly low and the client needs to be warmed. But none of these other vital signs take priority over the respiratory rate.

A registered nurse (RN) is watching a nursing student change a dressing and perform care around a Penrose drain. What action by the student warrants intervention by the RN? a. Cleaning around the drain per agency protocol b. Placing a new sterile gauze under the drain c. Securing the drain's safety pin to the sheets d. Using sterile technique to empty the drain

ANS: C The safety pin that prevents the drain from slipping back into the client's body should be pinned to the client's gown, not the bedding. Pinning it to the sheets will cause it to pull out when the client turns. The other actions are appropriate.

A client's intraocular pressure (IOP) is 28 mm Hg. What action by the nurse is best? a. Educate the client on corneal transplantation. b. Facilitate scheduling the eye surgery. c. Plan to teach about drugs for glaucoma. d. Refer the client to local Braille classes.

ANS: C This increased IOP indicates glaucoma. The nurse's main responsibility is teaching the client about drug therapy. Corneal transplantation is not used in glaucoma. Eye surgery is not indicated at this time. Braille classes are also not indicated at this time. Normal Range for IOP is 10-20 mm Hg

A nurse who is applying eyedrops to a client holds pressure against the corner of the eye nearest the nose after instilling the drops. The client asks what the nurse is doing. What response by the nurse is best? a. "Doing this allows time for absorption." b. "I am keeping the drops in the eye." c. "This prevents systemic absorption." d. "I am stopping you from rubbing your eye."

ANS: C This technique, called punctal occlusion, prevents eyedrops from being absorbed systemically. The other answers are inaccurate.

A nurse who is applying eyedrops to a client holds pressure against the corner of the eye nearest the nose after instilling the drops. The client asks what the nurse is doing. What response by the nurse is best? a. "Doing this allows time for absorption." b. "I am keeping the drops in the eye." c. "This prevents systemic absorption." d. "I am stopping you from rubbing your eye."

ANS: C This technique, called punctual occlusion, prevents eyedrops from being absorbed systemically. The other answers are inaccurate.

A client who is near blind is admitted to the hospital. What action by the nurse is most important? a. Allow the client to feel his or her way around. b. Let the client arrange objects on the bedside table. c. Orient the client to the room using a focal point. d. Speak loudly and slowing when talking to the client.

ANS: C Using a focal point, orient the client to the room by giving descriptions of items as they relate to the focal point. Letting the client arrange the bedside table is a good idea, but not as important as orienting the client to the room for safety. Allowing the client to just feel around may cause injury. Unless the client is also hearing impaired, use a normal tone of voice.

A client on the postoperative nursing unit has a blood pressure of 156/98 mm Hg, pulse 140 beats/min, and respirations of 24 breaths/min. The client denies pain, has normal hemoglobin, hematocrit, and oxygen saturation, and shows no signs of infection. What should the nurse assess next? a. Cognitive status b. Family stress c. Nutrition status d. Psychosocial status

ANS: D After ensuring the client's physiologic status is stable, these manifestations should lead the nurse to assess the client's psychosocial status. Anxiety especially can be demonstrated with elevations in vital signs. Cognitive and nutrition status are not related. Family stress is a component of psychosocial status.

A nurse is preparing a client for discharge after surgery. The client needs to change a large dressing and manage a drain at home. What instruction by the nurse is most important? a. "Be sure you keep all your postoperative appointments." b. "Call your surgeon if you have any questions at home." c. "Eat a diet high in protein, iron, zinc, and vitamin C." d. "Wash your hands before touching the drain or dressing."

ANS: D All options are appropriate for the client being discharged after surgery. However, for this client who is changing a dressing and managing a drain, infection control is the priority. The nurse should instruct the client to wash hands often, including before and after touching the dressing or drain.

A client is in the preoperative holding area waiting for cataract surgery. The client says "Oh, yeah, I forgot to tell you that I take clopidogrel, or Plavix." What action by the nurse is most important? a. Ask the client when the last dose was. b. Check results of the prothrombin time (PT) and international normalized ratio (INR). c. Document the information in the chart. d. Notify the surgeon immediately.

ANS: D Clopidogrel is an antiplatelet aggregate and could increase bleeding. The surgeon should be notified immediately. The nurse should find out when the last dose of the drug was, but the priority is to notify the provider. This drug is not monitored with PT and INR. Documentation should occur but is not the priority.

After teaching a young adult client who is newly diagnosed with type 1 diabetes mellitus, the nurse assesses the client's understanding. Which statement made by the client indicates a correct understanding of the need for eye examinations? a. "At my age, I should continue seeing the ophthalmologist as I usually do." b. "I will see the eye doctor when I have a vision problem and yearly after age 40." c. "My vision will change quickly. I should see the ophthalmologist twice a year." d. "Diabetes can cause blindness, so I should see the ophthalmologist yearly."

ANS: D Diabetic retinopathy is a leading cause of blindness in North America. All clients with diabetes, regardless of age, should be examined by an ophthalmologist (rather than an optometrist or optician) at diagnosis and at least yearly thereafter.

An older adult has been transferred to the postoperative inpatient unit after surgery. The family is concerned that the client is not waking up quickly and states "She needs to get back to her old self!" What response by the nurse is best? a. "Everyone comes out of surgery differently." b. "Let's just give her some more time, okay?" c. "She may have had a stroke during surgery." d. "Sometimes older people take longer to wake up."

ANS: D Due to age-related changes, it may take longer for an older adult to metabolize anesthetic agents and pain medications, making it appear that they are taking too long to wake up and return to their normal baseline cognitive status. The nurse should educate the family on this possibility. While everyone does react differently, this does not give the family any objective information. Saying "Let's just give her more time, okay?" sounds patronizing and again does not provide information. While an intraoperative stroke is a possibility, the nurse should concentrate on the more common occurrence of older clients taking longer to fully arouse and awake.

an older adult has a mild temperature, night sweats, and productive cough. The client's tuberculin test comes back negative. What action by the nurse is best? a. Recommend a pneumonia vaccination. b. Teach the client about viral infections. c. Tell the client to rest and drink plenty of fluids. d. Treat the client as if he or she has tuberculosis (TB).

ANS: D Due to an age-related decrease in circulating T lymphocytes, the older adult may have a falsely negative TB test. With signs and symptoms of TB, the nurse treats the client as if he or she does have TB. A pneumonia vaccination is not warranted at this time. TB is not a viral infection. The client should rest and drink plenty of fluids, but this is not the best answer as it does not address the possibility that the client's TB test could be a false negative.

After teaching a client who has diabetes mellitus and proliferative retinopathy, nephropathy, and peripheral neuropathy, the nurse assesses the client's understanding. Which statement made by the client indicates a correct understanding of the teaching? a. "I have so many complications; exercising is not recommended." b. "I will exercise more frequently because I have so many complications." c. "I used to run for exercise; I will start training for a marathon." d. "I should look into swimming or water aerobics to get my exercise."

ANS: D Exercise is not contraindicated for this client, although modifications based on existing pathology are necessary to prevent further injury. Swimming or water aerobics will give the client exercise without the worry of having the correct shoes or developing a foot injury. The client should not exercise too vigorously.

A client has arrived in the postoperative unit. What action by the circulating nurse takes priority? a. Assessing fluid and blood output b. Checking the surgical dressings c. Ensuring the client is warm d. Participating in hand-off report

ANS: D Hand-offs are a critical time in client care, and poor communication during this time can lead to serious errors. The postoperative nurse and circulating nurse participate in hand-off report as the priority. Assessing fluid losses and dressings can be done together as part of the report. Ensuring the client is warm is a lower priority.

A nurse teaches a client who is prescribed an insulin pump. Which statement should the nurse include in this client's discharge education? a. "Test your urine daily for ketones." b. "Use only buffered insulin in your pump." c. "Store the insulin in the freezer until you need it." d. "Change the needle every 3 days."

ANS: D Having the same needle remain in place through the skin for longer than 3 days drastically increases the risk for infection in or through the delivery system. Having an insulin pump does not require the client to test for ketones in the urine. Insulin should not be frozen. Insulin is not buffered.

A nurse reviews laboratory results for a client with diabetes mellitus who presents with polyuria, lethargy, and a blood glucose of 560 mg/dL. Which laboratory result should the nurse correlate with the client's polyuria? a. Serum sodium: 163 mEq/L b. Serum creatinine: 1.6 mg/dL c. Presence of urine ketone bodies d. Serum osmolarity: 375 mOsm/kg

ANS: D Hyperglycemia causes hyperosmolarity of extracellular fluid. This leads to polyuria from an osmotic diuresis. The client's serum osmolarity is high. The client's sodium would be expected to be high owing to dehydration. Serum creatinine and urine ketone bodies are not related to the polyuria.
