HESI RN
HESI Pharmacology Exam 2 Questions
Extract:
Question 1 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 2 of 5
The healthcare provider prescribes the antibiotic tetracycline HCl for an adult client that arrived at an outpatient clinic. Which instruction should the nurse include in the teaching plan for this client?
Correct Answer: B
Rationale: Tetracycline causes photosensitivity, increasing sunburn risk. Instructing the client to protect their skin from sunlight prevents skin damage. Orange juice, milk, or antacids reduce absorption, and serum levels are not routinely monitored for tetracycline.
Question 3 of 5
The nurse is caring for a client who has been taking ibuprofen. Which finding is most important for the nurse to report to the healthcare provider?
Correct Answer: A
Rationale: Hematemesis (vomiting blood) indicates potential gastrointestinal bleeding, a serious NSAID complication. Immediate reporting to the provider ensures evaluation and management. Nausea, insomnia, and dizziness are less urgent side effects of ibuprofen.
Question 4 of 5
The nurse is planning care for a client with major depression who is receiving a new prescription for duloxetine. Which information is most important for the nurse to obtain?
Correct Answer: C
Rationale: Duloxetine is metabolized by the liver, and hepatotoxicity is a rare but serious risk. Obtaining liver function test results ensures safe administration, as impaired liver function increases toxicity risk. Family history, weight changes, or other antidepressant use are relevant but secondary to liver function.
Question 5 of 5
A nurse is assessing a client’s ability to swallow. Which of the following, when selected by the nurse, indicates an understanding of the cranial nerve that tests the ability to swallow?
Correct Answer: C
Rationale: The glossopharyngeal nerve (IX) controls swallowing and the gag reflex. Selecting this nerve demonstrates understanding. The facial (VII) nerve manages facial expressions, trigeminal (V) handles chewing, and hypoglossal (XII) controls tongue movements.
