A client with 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 lb. 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.)

Here's how to calculate the total zidovudine dosage (mg) the nurse should prepare to administer: 1. Convert client weight to kilograms (kg): Weight (kg) = Weight (lbs) / 2.205 Weight (kg) = 185 lbs / 2.205 Weight (kg) ≈ 84.0 kg (round to one decimal place for better accuracy in calculation) 2. Calculate the total zidovudine dose based on weight and prescribed dosage: Dose (mg) = Prescribed dose (mg/kg) x Weight (kg) Dose (mg) = 2 mg/kg x 84.0 kg Dose (mg) = 168 mg (round to nearest whole number as requested) Therefore, the nurse should prepare to administer 168 mg of zidovudine.
