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 ["50"]
Explanation
First, we need to find out how many mL/hr the infusion pump is currently delivering.
Given:
The client is receiving 1,800 units/hour of heparin.
The available medication is 20,000 units/500 mL.
We can set up the proportion as follows:
1,800units/ xmL = 20,000units/500mL
Solving for x gives us the volume in mL that the infusion pump is currently delivering per hour.
Cross-multiplying and solving for x:
X = 1,800units×500mL/20,000units
After performing the calculation, we find that x equals 45 mL/hr.
Given that the healthcare provider prescribes an increase of 5 mL/hr in the IV rate, the nurse should set the infusion pump to deliver:
Newrate(mL/hr) = Currentrate(mL/hr) + Increase(mL/hr) = 45mL/hr+5mL/hr
After performing the calculation, we find that the new rate equals 50 mL/hr.
So, the nurse should set the infusion pump to deliver 50 mL/hr.
