Nursing Elites

1. A client with liver cirrhosis is receiving lactulose for hepatic encephalopathy. Which finding indicates the medication is effective?

• A. The client's level of consciousness improves.
• B. The client's ammonia level decreases.
• C. The client has three bowel movements daily.
• D. The client's liver enzymes return to normal.

Correct answer: B

Rationale: The correct answer is B: "The client's ammonia level decreases." In hepatic encephalopathy, elevated ammonia levels contribute to neurological symptoms. Lactulose works by promoting the excretion of ammonia in the stool, leading to decreased serum ammonia levels. Therefore, a decrease in ammonia levels indicates that lactulose is effectively reducing ammonia buildup, improving hepatic encephalopathy symptoms. Choices A, C, and D are incorrect because improvement in level of consciousness, bowel movements, or normalization of liver enzymes may not directly reflect the effectiveness of lactulose in reducing ammonia levels and improving hepatic encephalopathy.

2. 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.

3. A client admitted with left-sided heart failure presents with shortness of breath and pink frothy sputum. Which assessment finding requires immediate intervention?

• A. Decreased breath sounds bilaterally.
• B. Heart rate of 110 bpm and irregular rhythm.
• C. Pink frothy sputum and increased respiratory rate.
• D. Elevated blood pressure and shortness of breath.

Correct answer: C

Rationale: Correct Answer: Pink frothy sputum and increased respiratory rate. Pink frothy sputum is a sign of pulmonary edema, indicating fluid in the lungs, a life-threatening condition that requires immediate intervention to prevent respiratory failure. Increased respiratory rate is also concerning as it indicates the body's effort to compensate for the decreased oxygenation. Options A, B, and D are not the most critical findings in this situation. Decreased breath sounds bilaterally may indicate a pneumothorax or atelectasis, heart rate of 110 bpm and irregular rhythm can be managed with medications and further assessment, and elevated blood pressure with shortness of breath is not as urgent as pink frothy sputum and increased respiratory rate.

4. A client recently started on warfarin therapy. What laboratory value is most important to monitor for this client?

• A. Platelet count
• B. Prothrombin time (PT)
• C. Creatinine level
• D. Blood urea nitrogen (BUN)

Correct answer: B

Rationale: Prothrombin time (PT) is the most important laboratory value to monitor for clients on warfarin therapy. PT helps determine how long it takes blood to clot and ensures the warfarin dose is within the therapeutic range to prevent either excessive bleeding or clotting. Monitoring platelet count is important for assessing the risk of bleeding, but PT is more specific to warfarin therapy. Creatinine level and BUN are indicators of kidney function and are not directly related to warfarin therapy.

5. A client reports gastrointestinal upset after taking oral tetracycline. Which snack should the nurse recommend?

• A. Yogurt with fruit
• B. Toast with jelly
• C. Crackers with peanut butter
• D. Oatmeal with raisins

Correct answer: B

Rationale: The correct answer is B: Toast with jelly. Tetracycline can cause gastrointestinal upset when taken with dairy products. Yogurt with fruit (Choice A) contains dairy, which can worsen the gastrointestinal upset. Crackers with peanut butter (Choice C) and oatmeal with raisins (Choice D) are also not the best choices as they may not be gentle enough on the stomach. Toast with jelly is a simple snack that does not contain dairy and is less likely to exacerbate the gastrointestinal upset.
