Nursing Elites

1. A client with cirrhosis is admitted with hepatic encephalopathy. Which laboratory value requires immediate intervention?

• A. Serum ammonia level of 80 mcg/dl
• B. Bilirubin level of 3.0 mg/dl
• C. Serum sodium level of 135 mEq/L
• D. Prothrombin time of 18 seconds

Correct answer: D

Rationale: The correct answer is D. A prothrombin time of 18 seconds is most concerning in a client with hepatic encephalopathy as it indicates impaired liver function and an increased risk of bleeding. This requires immediate intervention to prevent bleeding complications. Choice A, serum ammonia level of 80 mcg/dl, is elevated but not as urgent as the abnormal prothrombin time. Choice B, bilirubin level of 3.0 mg/dl, is elevated but does not directly indicate an urgent need for intervention in this situation. Choice C, serum sodium level of 135 mEq/L, is within the normal range and does not require immediate intervention.

2. A client with a history of myocardial infarction is admitted with chest pain. Which laboratory value should the nurse monitor closely?

• A. White blood cell count
• B. Serum creatinine
• C. Troponin level
• D. Hemoglobin level

Correct answer: C

Rationale: The correct answer is C: Troponin level. Troponin levels should be closely monitored in a client with chest pain and a history of myocardial infarction to assess for ongoing myocardial injury. Troponin is a specific marker for myocardial damage. Monitoring white blood cell count (choice A) is not directly related to myocardial infarction. Serum creatinine (choice B) is more indicative of renal function rather than cardiac status. Hemoglobin level (choice D) is important but does not directly reflect ongoing myocardial injury.

3. A client with a history of chronic heart failure is admitted with shortness of breath and crackles in the lungs. Which laboratory value should be closely monitored?

• A. Serum creatinine of 2.0 mg/dL
• B. Serum sodium of 135 mEq/L
• C. Serum potassium of 5.5 mEq/L
• D. Blood glucose of 150 mg/dL

Correct answer: C

Rationale: A serum potassium level of 5.5 mEq/L should be closely monitored in a client with chronic heart failure as it may indicate hyperkalemia, requiring intervention. Hyperkalemia can lead to life-threatening cardiac arrhythmias in patients with heart failure. Serum creatinine (Choice A) is important to monitor for kidney function but is not the priority in this case. Serum sodium (Choice B) and blood glucose (Choice D) levels are not typically the primary focus when assessing a client with heart failure presenting with respiratory symptoms and crackles in the lungs.

4. A client with chronic heart failure is receiving furosemide (Lasix). Which laboratory value requires immediate intervention?

• A. Serum potassium of 3.0 mEq/L
• B. Serum sodium of 135 mEq/L
• C. Serum creatinine of 1.5 mg/dl
• D. Blood glucose of 200 mg/dl

Correct answer: A

Rationale: A serum potassium level of 3.0 mEq/L requires immediate intervention in a client receiving furosemide. Furosemide can cause potassium loss, leading to hypokalemia, which can be dangerous, especially in patients with heart failure. Hypokalemia can predispose the client to cardiac dysrhythmias, weakness, and other complications. Therefore, prompt intervention is necessary to prevent these adverse effects. Choice B (Serum sodium of 135 mEq/L) is within the normal range and does not require immediate intervention. Choice C (Serum creatinine of 1.5 mg/dl) may indicate kidney dysfunction but does not pose an immediate threat to the client's safety. Choice D (Blood glucose of 200 mg/dl) may suggest hyperglycemia, which is important but not as urgent as addressing hypokalemia in a client with heart failure receiving furosemide.

5. The mother of a one-month-old boy born at home brings the infant to his first well-baby visit. She mentions that he was born two weeks after his due date and is a 'good, quiet baby' who almost never cries. To assess for hypothyroidism, what question is most important for the nurse to ask the mother?

• A. Has your son had any immunizations yet?
• B. Is your son sleepy and difficult to feed?
• C. Are you breastfeeding or bottle feeding your son?
• D. Were any relatives born with birth defects?

Correct answer: B

Rationale: The correct answer is B. Sleepiness and difficulty feeding are key signs of congenital hypothyroidism, which requires early diagnosis and treatment. Asking about immunizations (choice A) is important but not directly related to assessing hypothyroidism. The feeding method (choice C) is relevant for overall health but not specific to hypothyroidism. Inquiring about relatives with birth defects (choice D) is not the most crucial question to assess hypothyroidism in this scenario.
