HESI Pharmacology Exam 2 Questions
Extract:
Question 1 of 5
The nurse is preparing a discharge teaching plan for a client who is taking ciprofloxacin hydrochloride tablets, which were prescribed because of a suspected anthrax exposure. Which instruction(s) should be included in the teaching plan? (Select all that apply.)
Correct Answer: C,D
Rationale: Ciprofloxacin is linked to tendonitis and rupture, requiring immediate reporting of tendon pain/swelling. Increased fluid intake prevents crystalluria, a side effect. Crushing tablets may alter efficacy, and NSAIDs increase seizure risk with ciprofloxacin, making these incorrect.
Question 2 of 5
After receiving five doses of filgrastim, the nurse notes that the client’s white blood cell count has increased from 2,500/mm3 (2.5 x 10^9/L) to 5,000/mm3 (5 x 10^9/L). Which action should the nurse implement? White Blood Cell (WBC) [Reference Range: 5000 to 10,000/mm3 (5 to 10 x 10^9/L)]
Correct Answer: D
Rationale: Filgrastim stimulates white blood cell production. An increase from 2,500 to 5,000/mm3 indicates effectiveness, though still at the lower normal range. Informing the client reinforces adherence. Culture reports, vital signs, or neutropenic precautions are unnecessary without infection signs.
Question 3 of 5
A client with chemotherapy-induced nausea receives a prescription for metoclopramide. Which adverse effect is most important for the nurse to report?
Correct Answer: C
Rationale: Involuntary movements (extrapyramidal symptoms) are a serious, potentially irreversible side effect of metoclopramide due to dopamine receptor blockade. Reporting these promptly allows intervention, such as dose adjustment or anticholinergic use. Nausea, diarrhea, and irritability are less urgent side effects.
Question 4 of 5
The nurse is providing instructions about a client’s new medications. How should the nurse explain the purpose of probenecid, a uricosuric drug?
Correct Answer: D
Rationale: Probenecid increases uric acid excretion in urine, reducing blood levels and preventing gout attacks. It does not affect kidney stone formation, urine stream strength, or urinary pain, making uric acid excretion the correct purpose.
Question 5 of 5
The nurse is administering the muscle relaxant baclofen by mouth (PO) to a client diagnosed with multiple sclerosis. Which intervention should the nurse implement?
Correct Answer: A
Rationale: Baclofen can cause dizziness or orthostatic hypotension, increasing fall risk in clients with multiple sclerosis, who may already have impaired coordination. Advising slow, cautious movement when rising and walking is the most critical intervention to prevent falls. Monitoring intake/output or muscle strength is not directly related to baclofen’s side effects, and abrupt discontinuation risks withdrawal.
