How many mL/hr should the nurse program the infusion pump to deliver? (Enter numeric value only. If rounding is required, round to the nearest whole number.)

How many mL should the nurse administer? (Enter numerical value only. If rounding is required, round to the nearest tenth.)

Correct Answer: 0.5

Rationale: Weight: 132 / 2.2 = 60 kg. Dose: 5 mcg/kg/day × 60 = 300 mcg/day. Concentration: 480 mcg / 0.8 mL = 600 mcg/mL. Volume: 300 / 600 = 0.5 mL. [Note: Document states 500.0 mL, likely a typo; correct calculation yields 0.5 mL.]
