Ati W26 Med Surg Final Proctored Exam
Calculation
The nurse prepares a continuous aminophylline infusion at 0.3 mg/kg/hr for a client weighing 165 pounds. The bag is mixed with 500 mg of aminophylline in 250 mL of D5W. At which rate should the nurse set the pump in mL/hr? Round the answer to the tenths place.
mL/hr
Explanation & Rationale
Step 1 is 165 lb ÷ 2.2 lb/kg = 75 kg. Step 2 is 75 kg × 0.3 mg/kg/hr = 22.5 mg/hr. Step 3 is (22.5 mg/hr ÷ 500 mg) × 250 mL = 11.25 mL/hr. Step 4 is 11.25 mL/hr rounded to the tenths place is 11.3 mL/hr..
