SECTION A: ICU INFUSION CALCULATIONS (1–30)




1. Norepinephrine order: 6 mcg/min

Bag: 4 mg in 250 mL
Rate?

A. 10 mL/hr
B. 15 mL/hr
C. 22.5 mL/hr
D. 40 mL/hr

Rationale: 4000 mcg ÷ 250 = 16 mcg/mL; 6×60 = 360 mcg/hr; 360 ÷ 16 =
22.5 mL/hr.




2. Dopamine 5 mcg/kg/min for 80 kg patient

Bag: 400 mg/250 mL
Rate?

,A. 10 mL/hr
B. 15 mL/hr
C. 25 mL/hr
D. 40 mL/hr

Rationale: 5×80=400 mcg/min → 24,000 mcg/hr; 400,000 mcg ÷ 250 = 1600
mcg/mL; 24,000 ÷ 1600 = 15 mL/hr.




3. Epinephrine 3 mcg/min

Bag: 4 mg/250 mL
Rate?

A. 5 mL/hr
B. 11.25 mL/hr
C. 20 mL/hr
D. 30 mL/hr

Rationale: 16 mcg/mL; 3×60=180 mcg/hr; 180 ÷ 16 = 11.25 mL/hr.




4. Dobutamine 10 mcg/kg/min for 70 kg

Bag: 250 mg/250 mL
Rate?

A. 20 mL/hr
B. 42 mL/hr
C. 50 mL/hr
D. 60 mL/hr

,Rationale: 700 mcg/min → 42,000 mcg/hr; 1000 mcg/mL → 42 mL/hr.




5. Insulin infusion: 8 units/hr

Bag: 100 units/100 mL
Rate?

A. 4 mL/hr
B. 8 mL/hr
C. 12 mL/hr
D. 16 mL/hr

Rationale: 1 unit/mL → direct conversion.




6. Heparin 1200 units/hr

Bag: 25,000 units/250 mL
Rate?

A. 8 mL/hr
B. 12 mL/hr
C. 20 mL/hr
D. 30 mL/hr

Rationale: 100 units/mL; 1200 ÷ 100 = 12 mL/hr.




7. Nitroglycerin 20 mcg/min

, Bag: 50 mg/250 mL
Rate?

A. 6 mL/hr
B. 10 mL/hr
C. 15 mL/hr
D. 20 mL/hr

Rationale: 200 mcg/mL; 1200 mcg/hr ÷ 200 = 6 mL/hr.




8. Vasopressin standard dose is:

A. 0.3 units/min
B. 0.03 units/min
C. 3 units/min
D. 1 unit/min

Rationale: Fixed low-dose infusion in septic shock.




9. MAP goal in ICU shock:

A. 50 mmHg
B. 55 mmHg
C. ≥65 mmHg
D. 90 mmHg

Rationale: Ensures organ perfusion.
