Nurs 4th Sem Mce A-fall 2025 Dosage Calculation Proctored Exam (Montgomery College)
Calculation
A nurse is preparing to administer Ringer's lactate 500 mL IV bolus to infuse over 3 hr. The drop factor of the manual IV tubing is 20 gtt/mL. The nurse should set 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 = 500 mL Infusion time = 3 hr × 60 min/hr = 180 min Drop factor = 20 gtt/mL Step 1: Calculate mL/min: 500 mL ÷ 180 min ≈ 2.78 mL/min Step 2: Calculate gtt/min: 2.78 mL/min × 20 gtt/mL ≈ 55.6 gtt/min ≈ 56 gtt/min Final Answer: 56 gtt/min
