Question 18 :
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.)
Correct Answer: ["68 mg"]
- Convert the client's weight from lbs to kg: 185 lbs / 2.2 = 84.09 kg - Multiply the client's weight by the prescribed dose: 84.09 kg x 2 mg/kg = 168.18 mg - Round the result to the nearest whole number: 168 mg
- The nurse should prepare to administer 168 mg of zidovudine IV over 1 hour.
