Practice Question
Order: Levaquin 350 mg is added to 500 mL D5W to infuse over 8 hours. Drop factor: 10 gtt/mL. For IV reconstitute with 1o mL. of diluent to get 100 mg per 10 mL. (Consider the medication added in the volume of fluid.) Calculate the rate in gtt/min at which the IV should infuse
Answer Choices:
Correct Answer:
10 gtt/min
Rationale:
🔷 Step 1: Total Volume to Infuse = 500 mL
(The medication is already added into the 500 mL D5W.)
🔷 Step 2: Total Infusion Time = 8 hours
8 hours × 60 minutes/hour = 480 minutes
🔷 Step 3: Drop Factor = 10 gtt/mL
🔷 Step 4: Apply the formula:
Flow rate (gtt/min) = Total volume (mL) × Drop factor (gtt/mL) ÷ Time (min)
Flow rate = 500 × 10 ÷ 480 = 5000 ÷ 480 = 10.4 ≈ 10 gtt/min
🔷 Final Answer: Round to the nearest whole number → 10 gtt/min
