Question 1 of 5
A nurse is preparing to administer aspirin 650 mg PO. Available in aspirin 325 mg tablets. How many tablets should the nurse administer?

Correct Answer: A
Rationale: Divide the total volume (750 mL) by the infusion time (8 hr): 750 mL ÷ 8 hr = 93.75 ≈ 94 mL/hr.

Correct Answer: B
Rationale: Calculate: (1200 mL ÷ 1440 min) × 15 gtt/mL = 12.495 ≈ 13 gtt/min.
