NCLEX-RN Exam Questions
Extract:
Question 1 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 2 of 5
The nurse is caring for a client with a history of a pulmonary embolism. The client is receiving Heparin. The nurse should monitor the client for:
Correct Answer: A
Rationale: Heparin, an anticoagulant, increases bleeding risk, including bleeding gums. Hypertension, tachypnea, and fever are not directly related to heparin therapy.
Question 3 of 5
The client is admitted with a suspected bowel obstruction. Which diagnostic test is most likely to confirm the diagnosis?
Correct Answer: A
Rationale: An abdominal X-ray is the initial test to confirm bowel obstruction, showing air-fluid levels or dilated loops of bowel. Barium enema and colonoscopy are contraindicated due to perforation risk, and ultrasound is less specific.
Question 4 of 5
A client who has sustained a basilar skull fracture exhibits blood-tinged drainage from his nose. After establishing a clear airway, administering supplemental O2, and establishing IV access, the next nursing intervention would be to:
Correct Answer: D
Rationale: Testing the fluid from the nares would determine the presence of CSF. Basilar skull fractures may cause dural lacerations, leading to CSF leakage. Insertion of a tube, tamponading, or suctioning could worsen the problem or increase brain damage.
Question 5 of 5
The nurse is preparing to administer a dose of insulin lispro (Humalog). When is the onset of action for this medication?
Correct Answer: A
Rationale: Insulin lispro, a rapid-acting insulin, has an onset of 5–15 minutes, making it ideal for pre-meal administration. Other insulins have slower onsets.
