Instructions: Perform each calculation, round to the nearest tenth (or whole number
where specified), and select the one best answer. Work must be shown mentally;
answers are final.
MODULE 1 – IV Flow Rate & Infusion Time (Q 1-15)
1. Order: Cefepime 2 g in 100 mL NS over 30 min.
Available: 2 g vial (reconstitute 10 mL) → 100 mL bag.
Pump required. mL/hr?
A. 100
B. 200
C. 300
D. 50
Answer: B
D.O.S.E. Check: 100 mL ÷ 0.5 hr = 200 mL/hr. Safe peripheral pump rate.
,2. Order: Heparin 25,000 units in 500 mL D5W at 1,200 units/hr.
Available: 25,000 units/5 mL → 500 mL bag.
mL/hr?
A. 12
B. 20
C. 24
D. 30
Answer: C
D.O.S.E. Check: Concentration = 25,000 ÷ 500 = 50 units/mL.
1,200 units/hr ÷ 50 units/mL = 24 mL/hr. Standard heparin drip.
3. Order: Amiodarone 900 mg in 500 mL D5W at 1 mg/min.
Available: 50 mg/mL → add 18 mL to 500 mL → 518 mL total.
Pump set to mL/hr (exam convention: use 500 mL diluent only).
mL/hr?
A. 18
B. 30
C. 33.3
D. 60
Answer: C
, D.O.S.E. Check: 900 mg ÷ 500 mL = 1.8 mg/mL.
1 mg/min × 60 min = 60 mg/hr.
60 mg/hr ÷ 1.8 mg/mL = 33.3 mL/hr. Exam simplification accepted.
4. Order: Insulin regular 8 units/hr IV.
Available: 100 units/100 mL (1 unit/mL).
mL/hr?
A. 6
B. 8
C. 10
D. 12
Answer: B
D.O.S.E. Check: 8 units/hr ÷ 1 unit/mL = 8 mL/hr. Simple unit-to-unit infusion.
5. Order: Magnesium sulfate 4 g in 250 mL NS over 2 hr.
Available: 4 g/20 mL → add to 250 mL → 270 mL total (exam: use 250 mL).
mL/hr?
A. 100
B. 125
C. 150
D. 200
