Nurs 4th Sem Mce A-fall 2025 Dosage Calculation Proctored Exam (Montgomery College)
Calculation
A nurse is preparing to administer vancomycin 1000 mg in 100 mL of DSW to infuse over 5 hours. The drop factor of the manual IV tubing is 15 gtt/mL. The nurse should adjust the manual IV infusion to deliver how many gtt/min? (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 = 1.5 hr × 60 min/hr = 90 min Drop factor = 15 gtt/mL Step 1: Calculate mL/min: 100 mL ÷ 90 min = 1.111 mL/min Step 2: Calculate gtt/min: 1.111 mL/min × 15 gtt/mL ≈ 16.7 gtt/min Final Answer: 17 gtt/min
