Calculation
A client is receiving 500 mg of metronidazole IVPB q8h. The metronidazole has been placed in 100 mL DSW to infuse over 45 minutes. The administration set delivers 10 gtt/mL. At what rate in gtt/min should the IV infuse? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
gtt/min
Explanation & Rationale
Rationale: Total volume = 100 mL Infusion time = 45 min Drop factor = 10 gtt/mL Step 1: Calculate mL/min: 100 mL ÷ 45 min ≈ 2.22 mL/min Step 2: Calculate gtt/min: 2.22 mL/min × 10 gtt/mL ≈ 22.2 gtt/min ≈ 22 gtt/min Final Answer: 22 gtt/min
