Nursing Elites

1. A client in a physician’s office has just made an appointment for an exercise stress test. The client should be instructed to:

• A. Wear sweatpants and a heavy sweatshirt
• B. Eat a small meal just before the procedure
• C. Wear comfortable rubber-soled shoes such as sneakers
• D. Avoid consuming caffeine for 30 minutes before the procedure

Correct answer: C

Rationale: The client should wear comfortable rubber-soled shoes, such as sneakers, for the exercise stress test. This choice ensures safety and stability during the procedure. Wearing sweatpants and a heavy sweatshirt (Choice A) would not be appropriate as the client needs to wear light, loose, comfortable clothing. Eating a small meal just before the procedure (Choice B) could lead to discomfort during the test. Avoiding caffeine for 30 minutes before the procedure (Choice D) is not a specific instruction related to the attire or preparation for the test.

2. A client with chronic renal failure is prescribed a low-protein diet. The nurse should explain to the client that the purpose of this diet is to:

• A. Prevent fluid overload.
• B. Reduce the workload on the kidneys.
• C. Prevent dehydration.
• D. Maintain electrolyte balance.

Correct answer: B

Rationale: The correct answer is B: 'Reduce the workload on the kidneys.' A low-protein diet is prescribed for clients with chronic renal failure to decrease the production of urea and other nitrogenous wastes, which can accumulate in the body when the kidneys are not functioning properly. This reduction in protein intake helps to lessen the burden on the kidneys, as they may have difficulty in filtering and excreting waste products. Choice A is incorrect because fluid overload is more related to restrictions in fluid intake rather than protein intake. Choice C is incorrect as a low-protein diet does not directly prevent dehydration. Choice D is incorrect because while electrolyte balance is essential in renal failure, the primary purpose of a low-protein diet is to reduce the workload on the kidneys by limiting the production of waste products.

3. After a session of hemodialysis, the nurse should monitor the client for which of the following complications of hemodialysis?

• A. Hyperkalemia.
• B. Hypotension.
• C. Infection.
• D. Fever.

Correct answer: B

Rationale: The correct answer is 'B: Hypotension.' Hypotension is a common complication of hemodialysis because fluid removal during the process can lead to a drop in blood pressure. The nurse should closely monitor the client for signs of hypotension such as dizziness, lightheadedness, or a decrease in blood pressure readings. Choice 'A: Hyperkalemia' is incorrect because hemodialysis actually helps lower potassium levels by removing excess potassium from the blood. Choice 'C: Infection' is incorrect as it is not a direct complication of hemodialysis but rather a risk associated with invasive procedures. Choice 'D: Fever' is incorrect as fever is not a typical immediate post-hemodialysis complication unless an underlying infection is present.

4. What do crackles heard on lung auscultation indicate?

• A. Cyanosis.
• B. Bronchospasm.
• C. Airway narrowing.
• D. Fluid-filled alveoli.

Correct answer: D

Rationale: Crackles heard on lung auscultation are caused by the popping open of small airways that are filled with fluid. This is commonly associated with conditions such as pulmonary edema, pneumonia, or heart failure. Cyanosis (Choice A) is a bluish discoloration of the skin and mucous membranes due to low oxygen levels in the blood, not directly related to crackles. Bronchospasm (Choice B) refers to the constriction of the airway smooth muscle, causing difficulty in breathing but does not typically produce crackles. Airway narrowing (Choice C) can lead to wheezing but is not directly linked to crackles heard on auscultation.

5. A client has an elevated blood urea nitrogen (BUN)/creatinine ratio. Which action should the nurse take first?

• A. Assess the client’s dietary habits.
• B. Inquire about the client's use of nonsteroidal anti-inflammatory drugs (NSAIDs).
• C. Hold the client’s metformin (Glucophage).
• D. Contact the health care provider immediately.

Correct answer: A

Rationale: An elevated blood urea nitrogen (BUN)/creatinine ratio can indicate various conditions such as dehydration, urinary obstruction, catabolism, or a high-protein diet. The initial action the nurse should take is to assess the client’s dietary habits to determine if the elevated ratio is related to diet. Inquiring about the use of NSAIDs is important as they can impact kidney function, but dietary causes should be ruled out first. Holding metformin or contacting the health care provider without assessing the dietary habits would be premature actions as they may not address the underlying cause of the elevated BUN/creatinine ratio.
