HESI RN 301 Pharmacology Final Exam Questions
Question 1 of 5
The nurse is administering SUBQ enoxaparin to a client following knee replacement surgery to prevent a deep vein thrombosis. Which laboratory result requires immediate action by the nurse?
Correct Answer: A
Rationale: A platelet count of 100,000/mm3 indicates thrombocytopenia, increasing bleeding risk with enoxaparin, requiring immediate action. Normal BUN, creatinine, and hematocrit do not warrant urgency.
Question 2 of 5
Before administering the initial dose of sumatriptan succinate to a client with a migraine headache, it is most important to determine if the client's history includes which problem?
Correct Answer: A
Rationale: Sumatriptan’s vasoconstrictive effects risk exacerbating coronary artery disease, potentially causing cardiac events. Rhinitis, diabetes, and IBS are less critical.
Question 3 of 5
When preparing to apply a scheduled fentanyl transdermal patch, the nurse notes that the previously applied patch is intact on the client's upper back and the client denies pain. Which action should the nurse take?
Correct Answer: B
Rationale: Fentanyl patches are replaced every 72 hours in a new location after removing the old patch to prevent overdose. Oral analgesics, provider consultation, or dual patches are inappropriate.
Question 4 of 5
A client receives a prescription for allopurinol. Which information provided by the client requires additional instruction by the nurse?
Correct Answer: B
Rationale: Doubling allopurinol after a missed dose risks toxicity; take the missed dose if time permits or skip it. Reducing caffeine/acid, taking with food, and drinking water are correct.
Question 5 of 5
A male client tells the home health nurse that he has started taking magnesium hydroxide and aluminum hydroxide to treat occasional heartburn. It is most important for the nurse to review the client's medical history regarding the presence of which disorder?
Correct Answer: C
Rationale: Magnesium and aluminum hydroxide are excreted renally, and renal disease can lead to accumulation, causing toxicity. Diabetes, thrombosis, and bronchitis are less directly affected.
