A physician order is written for a patient to receive 500 mL of normal saline IV over 8 hours. If the IV infusion set delivers 15 drops/mL, how many drops per minute should the patient receive?
- A. 15 drops/min
- B. 20 drops/min
- C. 32 drops/min
- D. 64 drops/min
Correct Answer: A
Rationale: If a patient were to receive 500 mL in 8 hours, dividing 500 by 8 would mean that the patient would receive 62.5 mL in 1 hour, or 60 minutes. Setting up the equation, 15 drops/mL/X = 62.5 mL/60 minutes, and cross-multiplying, the answer will be 15 drops/min.
