Calculation
A client is receiving a secondary infusion of vancomycin 1,500 mg in 250 mL to be infused over two hours. The intravenous (IV) administration set delivers 15 gtt/mL. How many gtt/min should the nurse regulate the infusion? (Enter numerical value only. If rounding is required, round to the nearest whole number.)
gtt/min
Explanation & Rationale
Step 1: Identify the total volume. 250 mL Step 2: Identify the infusion time. 2 hours = 120 minutes Step 3: Calculate the infusion rate. 250 ÷ 120 = 2.0833 mL/minute Step 4: Calculate the drops per minute. 2.0833 × 15 = 31.25 Rounded to the nearest whole number = 31 gtt/min
