Nursing Elites

1. The nurse is preparing an older adult for discharge following cataract extraction. What is the most important instruction?

• A. Avoid straining, bending, or lifting heavy objects.
• B. Limit exposure to sunlight for the first 2 weeks.
• C. Use direct lighting when reading for 6 weeks.
• D. Irrigate the conjunctiva with saline before applying ointment.

Correct answer: A

Rationale: The most important instruction for a patient following cataract extraction is to avoid straining, bending, or lifting heavy objects. These activities can increase intraocular pressure and potentially lead to complications such as bleeding or dislocation of the intraocular lens. Choices B, C, and D are not as critical in the immediate post-operative period. Limiting sunlight exposure and using direct lighting when reading are important but not as crucial as avoiding activities that can increase intraocular pressure. Irrigating the conjunctiva with saline before applying ointment is not a standard post-cataract surgery instruction.

2. A male client with hypertension, who received new antihypertensive prescriptions at his last visit returns to the clinic two weeks later to evaluate his blood pressure (BP). His BP is 158/106, and he admits that he has not been taking the prescribed medication because the drugs make him feel bad. In explaining the need for hypertension control, the nurse should stress that an elevated BP places the client at risk for which pathophysiological condition?

• A. Stroke secondary to hemorrhage
• B. Myocardial infarction
• C. Heart failure
• D. Renal failure

Correct answer: A

Rationale: Stroke is a major complication of uncontrolled hypertension. Elevated BP, especially at levels like 158/106, can cause damage to blood vessels in the brain, leading to a hemorrhagic stroke. Controlling BP is essential to prevent such life-threatening events. Myocardial infarction (choice B) is more commonly associated with coronary artery disease, while heart failure (choice C) and renal failure (choice D) can be complications of uncontrolled hypertension but are not directly related to the elevated BP leading to a hemorrhagic stroke.

3. A client with chronic liver disease is prescribed lactulose. Which laboratory value should the nurse monitor to evaluate the effectiveness of this medication?

• A. Bilirubin level
• B. Serum ammonia level
• C. Serum potassium level
• D. Albumin level

Correct answer: B

Rationale: The correct answer is B: Serum ammonia level. Lactulose is used to lower serum ammonia levels in clients with chronic liver disease, particularly in cases of hepatic encephalopathy. Monitoring serum ammonia levels is crucial to evaluate the effectiveness of lactulose in managing hepatic encephalopathy. Choices A, C, and D are incorrect because they are not directly related to the action or evaluation of lactulose in chronic liver disease.

4. A client with acute kidney injury (AKI) is experiencing hyperkalemia. What intervention should the nurse prioritize?

• A. Administer IV calcium gluconate.
• B. Administer sodium polystyrene sulfonate (Kayexalate).
• C. Administer insulin with dextrose.
• D. Restrict potassium intake in the client's diet.

Correct answer: A

Rationale: The correct intervention for a client with acute kidney injury (AKI) experiencing hyperkalemia is to administer IV calcium gluconate. Calcium gluconate helps stabilize the myocardium and prevent life-threatening arrhythmias in hyperkalemia by antagonizing the cardiac effects of high potassium levels. Choice B, administering sodium polystyrene sulfonate (Kayexalate), is used to lower potassium levels in the gastrointestinal tract but is not the priority in acute severe hyperkalemia. Choice C, administering insulin with dextrose, helps drive potassium into cells but is not the priority in a client at risk for arrhythmias due to hyperkalemia. Choice D, restricting potassium intake in the client's diet, is a long-term strategy but is not the immediate priority in managing acute hyperkalemia.

5. Which documentation indicates that activities to prevent postoperative venous stasis were performed correctly?

• A. Antiembolism stockings on, leg exercises performed hourly.
• B. Antiembolism stockings removed hourly during leg exercises.
• C. Leg exercises not performed due to antiembolism hose.
• D. Client demonstrates ability to move extremities well.

Correct answer: A

Rationale: The correct answer is A: 'Antiembolism stockings on, leg exercises performed hourly.' This documentation indicates the correct performance of activities to prevent postoperative venous stasis, as both components are crucial for prevention. Choice B is incorrect because removing stockings hourly is not recommended. Choice C is incorrect as leg exercises should be performed despite wearing antiembolism stockings. Choice D is incorrect as demonstrating the ability to move extremities well does not specifically address the prevention of venous stasis.
