Nursing Elites

1. A client with a history of chronic kidney disease (CKD) is admitted with hyperkalemia. Which assessment finding requires immediate intervention?

• A. Peaked T waves on the ECG
• B. Bradycardia
• C. Decreased deep tendon reflexes
• D. Muscle weakness

Correct answer: A

Rationale: Peaked T waves on the ECG are a critical finding in hyperkalemia as they indicate potential life-threatening cardiac arrhythmias. Immediate intervention is necessary to prevent cardiac complications such as ventricular tachycardia or fibrillation. Bradycardia, decreased deep tendon reflexes, and muscle weakness are not typically associated with hyperkalemia and do not pose the same level of immediate risk to the client's life.

2. Following discharge teaching, a male client with a duodenal ulcer tells the nurse he will drink plenty of dairy products to help coat and protect his ulcer. What is the best follow-up action by the nurse?

• A. Remind the client that it is also important to switch to decaffeinated coffee and tea.
• B. Suggest that the client also plans to eat frequent small meals to reduce discomfort.
• C. Review with the client the need to avoid foods that are rich in milk and cream.
• D. Reinforce this teaching by asking the client to list a dairy food that he might select.

Correct answer: C

Rationale: The correct answer is C because diets rich in milk and cream stimulate gastric acid secretion, which can exacerbate a duodenal ulcer. Therefore, it is essential to avoid foods that are rich in milk and cream. Choice A is incorrect because switching to decaffeinated coffee and tea does not address the issue of avoiding milk and cream products. Choice B is incorrect because while eating frequent small meals can help with discomfort, it does not address the specific issue of avoiding milk and cream. Choice D is incorrect as it does not address the need to avoid milk and cream products.

3. A client is admitted with a possible myocardial infarction. Which laboratory test result is most indicative of a myocardial infarction?

• A. Serum creatine kinase (CK)
• B. Serum troponin
• C. Serum myoglobin
• D. C-reactive protein (CRP)

Correct answer: B

Rationale: Serum troponin is the most specific and sensitive indicator of myocardial infarction. Troponin levels rise within 3-4 hours after myocardial damage, peak at 10-24 hours, and remain elevated for up to 10-14 days. Creatine kinase (CK) and myoglobin can also be elevated in myocardial infarction, but troponin is more specific to cardiac muscle damage. C-reactive protein (CRP) is a marker of inflammation and is not specific for myocardial infarction.

4. An elderly male client is admitted to the urology unit with acute renal failure due to a postrenal obstruction. Which question best assists the nurse in obtaining relevant historical data?

• A. Have you had any difficulty starting your urinary stream?
• B. Do you have a history of kidney stones?
• C. How much fluid do you drink daily?
• D. Have you had any previous urinary tract infections?

Correct answer: A

Rationale: The correct answer is A: 'Have you had any difficulty starting your urinary stream?' This question is the most relevant as difficulty starting urination can indicate an obstruction, which aligns with the client's current condition of postrenal obstruction causing acute renal failure. Choice B is incorrect as a history of kidney stones may not be directly related to the current obstruction. Choice C, asking about daily fluid intake, is not specific to the current issue of postrenal obstruction. Choice D inquires about previous urinary tract infections, which are not directly related to the current acute renal failure caused by postrenal obstruction.

5. In a client with heart failure receiving digoxin (Lanoxin) and furosemide (Lasix), which laboratory value requires immediate intervention?

• A. Serum potassium of 4.0 mEq/L
• B. Blood glucose of 200 mg/dl
• C. Serum creatinine of 1.5 mg/dl
• D. Serum potassium of 3.2 mEq/L

Correct answer: D

Rationale: A serum potassium level of 3.2 mEq/L is low and concerning in a client receiving digoxin and furosemide. Hypokalemia increases the risk of digoxin toxicity, leading to life-threatening arrhythmias. Therefore, immediate intervention is necessary to prevent complications. The other options, serum potassium of 4.0 mEq/L, blood glucose of 200 mg/dl, and serum creatinine of 1.5 mg/dl, are within normal limits and do not pose immediate risks to the client in this scenario.
