HESI RN 301 Pharmacology Final Exam Questions
Extract:
Question 1 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 2 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 3 of 5
A client with a history of angina reports the onset of chest pain. The nurse determines that the heart rate is 104 beats/minute and the blood pressure is 138/86 mm Hg. A transdermal nitroglycerin patch was applied 30 minutes ago to the right upper chest. Which action should the nurse take?
Correct Answer: A
Rationale: Sublingual nitroglycerin provides rapid relief for acute angina, complementing the slower-acting transdermal patch. Reassuring about delayed patch effects, withholding doses, or adding another patch are inappropriate for acute pain.
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
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.
