NCLEX-RN Exam Questions
Extract:
Question 1 of 5
A client is admitted to the hospital in chronic renal failure. A low protein diet is ordered. The rationale for a low protein diet is that:
Correct Answer: A
Rationale: In chronic renal failure, a low protein diet reduces the production of nitrogenous wastes like blood urea nitrogen (BUN), easing the kidneys’ workload. It does not directly affect sodium, potassium, albumin, calcium, or phosphorus levels.
Question 2 of 5
A client with a history of a total hip replacement is being discharged. The nurse should teach the client to avoid:
Correct Answer: B
Rationale: Crossing legs after a total hip replacement risks hip dislocation by adducting the femur. Sleeping, walking, or lying prone (if tolerated) are generally safe with proper precautions.
Question 3 of 5
The nurse is caring for an organ donor client with a severe head injury from an MVA. Which of the following is most important when caring for the organ donor client?
Correct Answer: A
Rationale: Maintaining BP at 90 mmHg or greater ensures organ perfusion, critical for organ viability in a donor. Normal temperature (
B) is important but secondary, low hematocrit (
C) is not a goal, and 300 mL/hr urine output (
D) is excessive.
Question 4 of 5
The physician prescribes regular insulin, five units subcutaneous. Regular insulin begins to exert an effect:
Correct Answer: C
Rationale: Regular insulin (short-acting) has an onset of 30–60 minutes when given subcutaneously, peaking at 2–3 hours. This allows time for absorption and glucose-lowering effects.
Question 5 of 5
The physician orders medication for a client's unpleasant side effects from the haloperidol. The most appropriate drug at this time is:
Correct Answer: C
Rationale: Lorazepam is a benzodiazepine, or antianxiety agent, that potentiates the effects of -aminobutyric acid in the CNS, which is not the CNS neurotransmitter EPS. Triazolam is a benzodiazepine sedative-hypnotic whose action is mediated in the limbic, thalamic, and hypothalamic levels of the CNS by -aminobutyric acid. Benztropine is an anticholinergic agent, and the drug of choice for blocking CNS synaptic response, which causes EPS. Thiothixene is an antipsychotic and neuroleptic drug that blocks dopamine neurotransmission at the CNS synapses, thereby causing EPS.
