Practice Questions with Correct Solutions
100% Pass Guarantee | IV Drip,
Conversions, Pediatric Doses
Exam Structure:
Subject: BSN HESI 215 Dosage Calculations Exam
Source: BSN HESI 215 Exam
Format: Dosage calculation problems with step-by-step Solutions.
1. Infusion Rate Calculation
Problem: The healthcare provider prescribes an IV Solution of 5%
dextrose in water with magnesium sulfate 4 gram/50 ml to be infused over
30 minutes. Program the infusion pump to deliver how many ml/hour?
(Enter numeric value only).
Solution:
1. Set up ratio: 50 ml : 30 minutes :: X ml : 60 minutes.
2. Solve: 50 ml / X ml = 30 min / 60 min -> 3000 = 30X -> X = 100
ml/hour.
Answer: 100
2. Tube Feeding Preparation
Problem: A client with a gastrostomy tube is receiving 3/4 strength Ensure
240 ml every 6 hours. Full strength Ensure is in a 240 ml can. How many ml
of Ensure are needed to prepare the feeding? (Enter numeric value only).
Solution:
1. Set up ratio for 3/4 (0.75) strength: 240 ml Ensure : 1 :: X ml Ensure :
0.75.
2. Solve: 240/X = 1/0.75 -> X = 240 × 0.75 = 180 ml Ensure.
3. Add water to reach 240 ml total: 180 ml Ensure + 60 ml water.

3. IV Infusion with Inamrinone
Problem: 0.9% normal saline with inamrinone (Inocor) 0.1 grams/100 ml
is prescribed to be delivered at 400 mcg/minute. Program the infusion
pump to deliver how many ml/hour? (Enter numeric value only).
Solution:
1. Calculate mcg/hour: 400 mcg/min × 60 min = 24,000 mcg/hour.
2. Calculate ml/hour: 100,000 mcg : 100 ml :: 24,000 mcg : X ml.
3. Solve: 100,000/24,000 = 100/X -> 100,000X = 2,400,000 -> X = 24
ml/hour.
Answer: 24
4. IV Infusion with Milrinone
Problem: A client receives 0.9% normal saline with milrinone (Primacor)
10 mg in 100 ml at 46 mcg/minute. Program the infusion pump to deliver
how many ml/hour? (Enter numeric value only).
Solution:
1. Calculate mcg/hour: 46 mcg/min × 60 min = 2760 mcg/hour.
2. Calculate ml/hour: 10,000 mcg : 100 ml :: 2760 mcg : X ml.
3. Solve: 10,000/2760 = 100/X -> 10,000X = 276,000 -> X = 27.6 ≈ 28
ml/hour.
Answer: 28
5. Weight-Based Dopamine Infusion
Problem: Dextrose 5% in water with dopamine 0.6 grams/250 ml is
prescribed at 5 mg/kg/minute for a client weighing 148 lbs. Set the
infusion pump to how many ml/hour? (Enter numeric value only).
Solution:
1. Convert weight to kg: 148 lbs / 2.2 kg/lb = 67 kg.
2. Calculate mcg/kg/min: 5 mg/kg/min = 5000 mcg/kg/min.
3. Calculate mcg/min: 5000 mcg/kg/min × 67 kg = 335,000 mcg/min.
4. Calculate mcg/hour: 335,000 mcg/min × 60 min = 20,100,000
mcg/hour.
5. Calculate ml/hour: 600,000 mcg : 250 ml :: 20,100,000 mcg : X ml.
6. Solve: 600,000/20,100,000 = 250/X -> 600,000X = 5,025,000,000 ->
X = 8.375 ≈ 8 ml/hour.
