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
