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.

Correct Answer is ["0.5"]
Explanation
Here's how to calculate the volume the nurse should administer after reconstituting the medication:
1. Reconstitution and Concentration:
The medication label states adding 2.5 mL of normal saline will make a solution with a concentration of 1 gram per mL. This means after reconstituting, each 1 mL of the solution will contain 1 gram of medication.
2. Dose conversion:
The client's prescription is for 500 mg. We need to convert it to grams since the concentration is in grams per mL.
Conversion: 1 gram (g) = 1000 milligrams (mg)
Prescribed dose (g) = 500 mg / 1000 mg/g
Prescribed dose (g) = 0.5 g (round to nearest tenth)
3. Calculate the volume to administer:
We know the concentration after reconstitution (1 gram/mL) and the desired dose in grams (0.5 g).
Volume to administer (mL) = Dose (g) / Concentration (g/mL)
Volume to administer (mL) = 0.5 g / 1 g/mL
Volume to administer (mL) = 0.5 mL (round to nearest tenth as requested)
Therefore, the nurse should administer approximately 0.5 mL of the reconstituted medication to the client.
Correct Answer is ["1"]
Explanation
First, let’s convert the client’s weight from pounds to kilograms since the dosage is prescribed in mcg/kg.
We know that 1 kg is approximately 2.2 lbs. So,
Weightinkg = 2.2154lbs ≈ 70kg
The prescribed dose is 1.6 mcg/kg.
Therefore, the total dose for this client would be:
Doseinmcg = 1.6mcg/kg×70kg = 112mcg
The medication is available in 112 mcg tablets.
Therefore, to administer a dose of 112 mcg, the nurse should administer 1 tablet
