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 from pounds to kilograms: Client weight (kg) = Client weight (lb) / 2.2 Client weight (kg) = 185 lb / 2.2 Client weight (kg) = 84.1 kg (approximately) 2. Calculate the total zidovudine dose based on weight and prescribed dosage: Dose (mg) = Dose (mg/kg) x Client weight (kg) Dose (mg) = 2 mg/kg x 84.1 kg Dose (mg) = 168.2 mg (round to nearest whole number as requested) Therefore, the nurse should prepare to administer 168 mg of zidovudine.
