NCLEX-RN Exam Questions
Extract:
Question 1 of 5
A client scheduled for disc surgery tells the nurse that she frequently uses the herbal supplement kava-kava (piper methysticum). The nurse should notify the doctor because kava-kava:
Correct Answer: A
Rationale: Kava-kava can potentiate the effects of anesthesia and analgesics, increasing the risk of excessive sedation or respiratory depression, necessitating physician awareness.
Question 2 of 5
A client with a history of a brain tumor is scheduled for a craniotomy. The nurse should:
Correct Answer: B
Rationale: Antibiotics are often given preoperatively for a craniotomy to prevent infection. Shaving is per protocol, flat positioning may increase ICP, and exercises are taught post-op.
Question 3 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.
Question 4 of 5
A client has returned to the unit following a left femoral popliteal bypass graft. Six hours later, his dorsalis pedis pulse cannot be palpated, and his foot is cool and dusky. The nurse should:
Correct Answer: B
Rationale: The physician should be notified immediately because the client is losing blood supply to his left foot and is in danger of losing the foot and/or leg.
Question 5 of 5
The nurse is assessing a client with suspected hyperthyroidism. Which finding is most consistent with this diagnosis?
Correct Answer: C
Rationale: Tremors are a common sign of hyperthyroidism due to increased metabolic rate and sympathetic activity. Weight gain, bradycardia, and constipation are more typical of hypothyroidism.
