HESI Pharmacology Exam 2 Questions
Extract:
Question 1 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.
Question 2 of 5
A client receives a new prescription for levothyroxine. Which statement made by the client indicates to the nurse the education was effective?
Correct Answer: D
Rationale: Levothyroxine is best absorbed on an empty stomach, at least 30 minutes before breakfast, to ensure optimal efficacy. High-iodine foods may affect thyroid function, bedtime dosing risks insomnia, and iron supplements should be taken separately but not avoided entirely.
Question 3 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 4 of 5
The nurse initiates an infusion of piperacillin-tazobactam for a client with a urinary tract infection. Five minutes into the infusion, the client reports not feeling well. Which client manifestation should the nurse identify as a reason to stop the infusion?
Correct Answer: A
Rationale: A scratchy throat may signal an allergic reaction to piperacillin-tazobactam, a penicillin derivative, potentially progressing to anaphylaxis. Stopping the infusion immediately prevents severe complications. Pupillary constriction, hypertension, and bradycardia are not typical allergic responses and require monitoring but not immediate cessation.
Question 5 of 5
Prior to administering oral doses of calcitriol and calcium carbonate to a client with hypoparathyroidism, the nurse notes that the client’s total calcium level is 14 mg/dL (3.5 mmol/L). Which action should the nurse implement? Reference Range: Total Calcium [Reference Range: Adult 9 to 10.5 mg/dL or 2.25 to 2.62 mmol/L]
Correct Answer: B
Rationale: A calcium level of 14 mg/dL indicates hypercalcemia, risking complications like arrhythmias. Holding both calcitriol and calcium carbonate and contacting the provider prevents further calcium elevation. Administering either medication could worsen hypercalcemia, making holding both the safest action.
