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.)

Answer and Explanation

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 ["0.64"]

Explanation

Here's the calculation to determine the volume to administer:

Prescribed dose: 40 mg methylprednisolone

Medication vial concentration: 125 mg per 2 mL (given on the vial label)

We need to find the volume (mL) containing the prescribed dose (40 mg) of methylprednisolone.

Calculation:

Volume to administer (mL) = Dose (mg) / Concentration (mg/mL)

Since the concentration is given in mg per 2 mL, we need to adjust it to mg/mL for accurate calculation:

Concentration (mg/mL) = Total mg / Volume (mL)

Concentration (mg/mL) = 125 mg / 2 mL

Concentration (mg/mL) = 62.5 mg/m

Now, with the concentration in mg/mL, we can calculate the volume to administer:

Volume to administer (mL) = 40 mg / 62.5 mg/mL

Volume to administer (mL) = 0.64 mL (round to nearest hundredth as requested)

Therefore, the nurse should administer 0.64 mL of methylprednisolone.

Correct Answer is ["2.4"]

Explanation

The vial contains 500 mcg (or 0.5 mg) of digoxin in 2 mL.

This means that each mL contains 0.25 mg of the medication (0.5 mg / 2 mL = 0.25 mg/mL).

The nurse needs to administer 0.6 mg of the medication. To find out how many mL this is, we divide the dose by the concentration:

VolumeinmL = 0.25mg/mL 0.6mg / 0.25mg/mL = 2.4mL

If rounding is required to the nearest tenth, the nurse should administer 2.4 mL of the medication.
