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.)
The Correct Answer is ["168"]
here's how to calculate the total zidovudine dosage the nurse should prepare for the client:
Client weight conversion:
Client weight: 185 lbs
Medication dosage is based on weight per kilogram (kg). Therefore, we need to convert the weight to kg for accurate calculation.
Conversion factor: 1 kg = 2.205 lbs
Client weight (kg) = 185 lbs / 2.205 lbs/kg
Client weight (kg) = 84.0 kg (round to nearest tenth)
Prescribed zidovudine dose per kilogram:
Dose per kg: 2 mg/kg (given)
Calculate the total zidovudine dosage (mg) for the client:
Total dose (mg) = Dose per kg (mg/kg) x Client weight (kg)
Total dose (mg) = 2 mg/kg * 84.0 kg
Total dose (mg) = 168 mg (round to nearest whole number)
Therefore, the nurse should prepare approximately 168 mg of zidovudine for the client.

Explanation
Here's how to calculate the maximum daily dose of acetaminophen for the child:
Calculate the maximum dose per administration:
Maximum dose per kg per administration = 15 mg/kg (given)
Child's weight = 40 kg (given)
Since this is a PRN medication (given as needed), we will calculate the maximum dose per administration based on the prescribed dosage.
Maximum dose per administration = 15 mg/kg/dose * 40 kg
Maximum dose per administration = 600 mg (round to nearest whole number)
Calculate the number of administrations in a 24-hour period (maximum):
Frequency: Every 4 to 6 hours PRN (given)
Since this is a PRN medication, we will assume the maximum frequency (every 4 hours) for calculating the maximum daily dose.
Number of administrations (maximum) = 24 hours / Frequency (hours/administration)
Number of administrations (maximum) = 24 hours / 4 hours/administration
Number of administrations (maximum) = 6 administrations
Calculate the maximum daily dose:
Maximum daily dose = Maximum dose per administration x Number of administrations (maximum)
Maximum daily dose = 600 mg/administration * 6 administrations
Maximum daily dose = 3600 mg
Therefore, the maximum daily dose the nurse should administer is 3600 mg.
Correct Answer is ["168"]
Explanation
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.
