NCLEX RN Nursing Exam Questions
Extract:
Question 1 of 5
The physician has ordered 50 mEq of potassium chloride for a client with a potassium level of 2.5 mEq/L. The nurse should administer the medication:
Correct Answer: C
Rationale: Potassium chloride for hypokalemia (2.5 mEq/L) should be administered via controlled IV infusion over several hours (e.g., five hours) to prevent rapid shifts that could cause arrhythmias.
Question 2 of 5
The client is admitted with a possible myocardial infarction. The nurse would anticipate an order from the physician for which laboratory test?
Correct Answer: A, C, D
Rationale: Creatine kinase (
A), myoglobin (
C), and troponin T (
D) are cardiac biomarkers elevated in myocardial infarction. Ammonia (
B), gamma-glutamyl transferase (E), and bilirubin (F) are unrelated to acute cardiac events.
Question 3 of 5
The nurse is caring for a client with a suspected stroke. Which assessment finding is most concerning?
Correct Answer: B
Rationale: Unilateral facial droop is a classic sign of stroke, indicating neurological deficit and requiring urgent evaluation. Headache (
A), dizziness (
C), and fatigue (
D) are less specific.
Question 4 of 5
During the assessment, the nurse observes a client scratching his skin. He has been admitted to rule out Laennec's cirrhosis of the liver. The nurse knows the pruritus is directly related to:
Correct Answer: B
Rationale: A loss in the phagocytic activity of the Kupffer cells occurs with cirrhosis of the liver, which increases the susceptibility to infections. The faulty processing of bilirubin produces bile salts, which are irritating to the skin. The detoxification of drugs is impaired with cirrhosis of the liver. Collateral circulation develops due to portal hypertension. This is manifest through the development of esophageal varices, hemorrhoids, and caput medusae.
Question 5 of 5
A client who uses a respiratory inhaler asks the nurse to explain how he can know when half his medication is empty so that he can refill his prescription. The nurse should tell the client to:
Correct Answer: B
Rationale: Dropping the inhaler in water to see if it floats is a practical way to estimate remaining medication; a half-empty inhaler will float, while a full one sinks.
