Ati dosage calculation rn maternal newborn proctored assessment 3.2-Mesh
Calculation
A nurse is preparing to administer dobutamine 10 mcg/kg/min by continuous IV infusion to a newborn who weighs 4 kg. Available is dobutamine 250 mg in 500 mL dextrose 5% in water. The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
mL/hr
Explanation & Rationale
Step 1 is (10 mcg/kg/min × 4 kg) = 40 mcg/min Step 2 is (40 mcg/min ÷ 1000) = 0.04 mg/min Step 3 is (0.04 mg/min × 60 min/hr) = 2.4 mg/hr Step 4 is (2.4 mg/hr ÷ 250 mg) × 500 mL = 4.8 mL/hr. Final answer: 4.8 mL/hr.
