HESI RN 301 Pharmacology Final Exam Questions
Extract:
Question 1 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 2 of 5
Based on the capillary glucose measurement, a client is to receive 10 units of regular insulin. The client's medication drawer contains one vial of a 70/30 mixture of regular insulin and isophane insulin. How should the nurse prepare the prescribed dose?
Correct Answer: C
Rationale: A 70/30 vial contains 30% regular insulin, so 10 units yields only 3 units regular insulin. Withholding until regular insulin is available ensures accurate dosing.
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
The nurse is preparing client teaching materials on commonly used medications. Which client is most likely to benefit from a client education packet about simvastatin?
Correct Answer: B
Rationale: Simvastatin lowers cholesterol, benefiting those with angina due to coronary artery disease risk. Vaginal infections, pregnancy (contraindicated), and bone cancer are unrelated.
Question 5 of 5
A male client is admitted for observation because he is reporting progressively increasing fatigue over the past month and a brief episode of dizziness that occurred today. He has a history of heartburn and indigestion that he self-treats with ibuprofen and antacids. Which assessment finding should the nurse report immediately to the healthcare provider?
Correct Answer: B
Rationale: Positive guaiac indicates gastrointestinal bleeding, likely from ibuprofen-induced ulcers, requiring urgent reporting. Normal hematocrit, gastric pH, and slightly low hemoglobin are less immediate.
