HESI RN 301 Pharmacology Final Exam Questions
Extract:
Question 1 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
An older female client comes to the clinic for a regular check-up. The client tells the nurse that she has increased her daily doses of acetaminophen for the past month to control joint pain. Based on this patient's comment, which previous laboratory results should the nurse compare with today's laboratory report?
Correct Answer: D
Rationale: High acetaminophen doses risk hepatotoxicity, potentially elevating LDH, a marker of liver damage. Potassium, APTT, and hemoglobin/hematocrit are not primarily affected by acetaminophen overuse.
Question 4 of 5
A client is receiving morphine sulfate via a patient-controlled analgesia (PCA) pump postoperatively. Which assessment finding should prompt the nurse to administer a prescribed PRN dose of naloxone?
Correct Answer: B
Rationale: A respiratory rate of 7 breaths/minute indicates severe opioid-induced respiratory depression, requiring naloxone. Other findings suggest distress but are less specific for opioid overdose.
Question 5 of 5
A daily dose of aspirin 325 mg PO is most beneficial for an adult client with which medical diagnosis?
Correct Answer: C
Rationale: Aspirin 325 mg daily prevents clot formation in myocardial infarction patients, reducing recurrence risk. It’s not primary for gout, sepsis, or rheumatoid arthritis management.
