NCLEX RN Predictor Exam Questions
Extract:
Question 1 of 5
The nurse is caring for a client with a diagnosis of ectopic pregnancy. Which diagnostic test is most appropriate?
Correct Answer: C
Rationale: Ultrasound confirms the ectopic pregnancy’s location and serum hCG levels show abnormal doubling patterns. Both tests are critical for diagnosis.
Question 2 of 5
A client with a history of heart failure is admitted with shortness of breath and leg edema. Which medication would the nurse expect to administer?
Correct Answer: B
Rationale: Furosemide, a diuretic, reduces fluid overload in heart failure, relieving shortness of breath and edema. Metoprolol (
A) manages heart rate, Warfarin (
C) prevents clots, and Atorvastatin (
D) lowers cholesterol, but none address fluid directly.
Question 3 of 5
The nurse monitors a client with SIADH for weight loss. A loss of 6 pounds since admission indicates a loss of liters of fluid.
Correct Answer: 2.7 liters
Rationale: In SIADH, 1 kg (2.2 lbs) of weight loss approximates 1 liter of fluid loss. 6 lbs ÷ 2.2 = 2.73 kg ≈ 2.7 liters.
Question 4 of 5
The client is admitted with a diagnosis of ectopic pregnancy. Which laboratory test is most likely to be ordered?
Correct Answer: A
Rationale: Serum hCG levels are critical in ectopic pregnancy to monitor abnormal doubling patterns aiding diagnosis. CBC and urinalysis may be ordered for general assessment but are less specific.
Question 5 of 5
A client with a head injury has an intracranial pressure (ICP) monitor in place. Cerebral perfusion pressure calculations are ordered. If the client's ICP is 22 and the mean pressure reading is 70, what is the client's cerebral perfusion pressure?
Correct Answer: 58
Rationale: Cerebral perfusion pressure (CPP) is calculated as CPP = MAP - ICP. Given MAP = 70 mmHg and ICP = 22 mmHg, CPP = 70 - 22 = 48 mmHg. Thus, the correct answer is 48.
