Calculation
A client with human immunodeficiency virus (HIV) begins active labor at 38 weeks gestation and receives a prescription for zidovudine 2 mg/kg IV, to be administered over 1 hour. The client weighs 185 lbs. Based on the client's weight, how many mg should the nurse prepare to administer? (Enter numerical value only. If rounding is required, round to the nearest whole number.)
mg
Explanation & Rationale
First, convert pounds to kilograms: 185 lbs × 0.453592 kg/lb ≈ 83.91 kg Now, calculate the dosage: Dosage = 2 mg/kg × 83.91 kg ≈ 167.82 mg ≈ 168 mg The nurse should prepare approximately 168 mg of zidovudine for administration based on the client's weight.
