Nurs 4th Sem Mce A-fall 2025 Dosage Calculation Proctored Exam (Montgomery College)
Calculation
A nurse is preparing to administer cefazolin 500 mg by intermittent IV bolus over 30 min. Available is cefazolin 500 mg in 50 mL dextrose 5% in water (DSW). The drop factor of the manual IV tubing is 10 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 = 50 mL Infusion time = 30 min Drop factor = 10 gtt/mL Step 1: Calculate mL/min: 50 mL ÷ 30 min ≈ 1.67 mL/min Step 2: Calculate gtt/min: 1.67 mL/min × 10 gtt/mL ≈ 16.7 gtt/min ≈ 17 gtt/min Final Answer: 17 gtt/min
