The health care provider orders an IV aminophylline infusion at 30 mg/hr. The pharmacy sends a 1,000 ml bag of D5W containing 500 mg of aminophylline. In order to administer 30 mg per hour, the RN will set the infusion rate at:
- A. 20 ml per hour
- B. 30 ml per hour
- C. 50 ml per hour
- D. 60 ml per hour
Correct Answer: D
Rationale: 60 ml per hour. Using the ratio method to calculate infusion rate: mg to be given (30) : ml to be infused (X) :: mg available (500) : ml of solution (1,000). Solve for X by cross-multiplying: 30 × 1,000 = 500 × X, 30,000 = 500X, X = 30,000 / 500, X = 60 ml per hour.
