NCLEX Practice Test PN Questions
Extract:
Question 1 of 5
The nurse is teaching a group of adults about modifiable cardiac risk factors. Which of the following should the nurse focus on first?
Correct Answer: D
Rationale: Smoking cessation. Stopping smoking is the priority for clients at risk for cardiac disease, because of its effects of reducing oxygenation and constricting blood vessels.
Question 2 of 5
The nurse is preparing to administer the fourth dose of IV vancomycin to a client. Which set of laboratory values would alert the nurse to hold the vancomycin and notify the health care provider?
Correct Answer: D
Rationale: A vancomycin trough of 23 mg/L is above the therapeutic range (10-20 mg/L), indicating potential toxicity. Elevated creatinine (1.5 mg/dL) suggests renal impairment, which increases the risk of vancomycin accumulation and nephrotoxicity.
Question 3 of 5
A nurse is admitting a client at 42 weeks gestation to the labor and delivery unit for induction of labor. What is a predictor of a successful induction?
Correct Answer: A
Rationale: A Bishop score of 10 indicates a favorable cervix (soft, dilated, effaced, anterior), predicting a higher likelihood of successful induction.
Question 4 of 5
The nurse is teaching parents about the treatment plan for a 2 weeks-old infant with Tetralogy of Fallot. While awaiting future surgery, the nurse instructs the parents to immediately report
Correct Answer: A
Rationale: Loss of consciousness. This indicates anoxia, which may lead to death, requiring immediate reporting.

Correct Answer: B
