HESI RN 301 Pharmacology Final Exam Questions
Extract:
Question 1 of 5
A client is scheduled for a spiral computed tomography (CT) scan with contrast to evaluate for pulmonary embolism. Which information in the client's history requires follow up by the nurse?
Correct Answer: A
Rationale: Metformin risks lactic acidosis with contrast dye, requiring follow-up to hold the drug and monitor renal function. Prostheses, sobriety, and prior scans are less critical.
Question 2 of 5
A client with hepatic encephalopathy is receiving lactulose. Which assessment provides the nurse with the best information to evaluate the client's therapeutic response to the medication?
Correct Answer: D
Rationale: Lactulose reduces ammonia in hepatic encephalopathy, so monitoring serum ammonia and electrolytes (due to laxative effects) best evaluates response. Glucose, stool, and hepatic enzymes are less direct indicators.
Question 3 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 4 of 5
Levothyroxine sodium is prescribed for a client with hypothyroidism. The nurse should instruct the client to report which symptom because it indicates that the client is taking too much levothyroxine sodium?
Correct Answer: A
Rationale: Excessive levothyroxine can cause hyperthyroidism symptoms, like restlessness, due to increased metabolism. Decreased appetite, cold intolerance, and constipation are associated with hypothyroidism, not overdose.
Question 5 of 5
The nurse is assessing a patient who is receiving metoprolol 2 days after an acute coronary syndrome (ACS). Which physiological action of metoprolol supports the desired or therapeutic response?
Correct Answer: C
Rationale: Metoprolol, a beta-blocker, reduces heart rate and blood pressure, decreasing afterload to lower cardiac workload post-ACS. It reduces contractility, doesn’t increase preload, and increases filling time.
