HESI RN 301 Pharmacology Final Exam Questions
Extract:
Question 1 of 5
The nurse is assessing the eyes of a client who just received mydriatic eye drops. Which physiological function of the eye will not respond during the therapeutic period after administration of the eye drops?
Correct Answer: B
Rationale: Mydriatic drops dilate pupils, inhibiting constriction during their effect. Accommodation, refraction, and convergence may be indirectly affected but remain functional.
Question 2 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 3 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 4 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 5 of 5
Prior to administering oral doses of calcitriol and calcium carbonate to a client with hypoparathyroidism, the nurse notes that the client's total calcium level is 14 mg/dl (3.5 mmol/l). Which action should the nurse implement?
Correct Answer: D
Rationale: A calcium level of 14 mg/dL indicates hypercalcemia, risking toxicity. Both calcitriol and calcium carbonate increase calcium levels, so holding both and contacting the provider is safest.
