The nurse is preparing to administer ampicillin PO to a 12-year-old child with impetigo who weighs 88 pounds. The prescription is for 50 mg/kg/day. How many mg should the child receive per day? (Enter numeric value only.)
Answer and Explanation

The Correct Answer is ["2000"]

Here's how to calculate the total milligrams of ampicillin the child should receive per day:

Convert child's weight to kilograms:

Weight (kg) = Weight (lbs) / Conversion factor (lbs/kg)

Weight (kg) = 88 lbs / 2.205 lbs/kg

Weight (kg) = 40 kg (round to nearest whole number)

Calculate the total daily dosage:

Daily dosage (mg) = Dose per kg (mg/kg/day) * Weight (kg)

Daily dosage (mg) = 50 mg/kg/day * 40 kg

Daily dosage (mg) = 2000 mg

Therefore, the child should receive 2000 mg of ampicillin per day.

Correct Answer is ["0.1"]

Explanation

Here's how to calculate the volume the nurse should administer:

1. Dose of cyanocobalamin (vitamin B12): 100 mcg

2. Concentration of cyanocobalamin in the vial: 1 mg/mL (given on the vial label)

We need to find the volume (in mL) that contains the prescribed dose (100 mcg) of cyanocobalamin.

Calculation:

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

Note: Since both the medication dose and concentration are given in mcg units, we can directly perform the calculation without converting units.

Volume to administer (mL) = 100 mcg / 1 mg/mL

Conversion:

1 mg is equal to 1000 mcg. Therefore, 1 mg/mL is the same as 1000 mcg/mL.

Volume to administer (mL) = 100 mcg / (1000 mcg/mL)

Volume to administer (mL) = 0.1 mL (round to nearest tenth as requested)

Therefore, the nurse should administer approximately 0.1 mL of the cyanocobalamin injection.

Correct Answer is ["1.3"]

Explanation

Here's how to calculate the volume (mL) of filgrastim the nurse should administer:

Client weight conversion:

Client weight: 176 pounds

Since medication dosage is based on weight per kilogram (kg), we need to convert the weight to kg for accurate calculation.

Conversion factor: 1 kg = 2.205 lbs

Client weight (kg) = 176 pounds / 2.205 lbs/kg

Client weight (kg) = 80 kg (round to nearest whole number)

Filgrastim dose per kg:

Dose per kg = 5 mcg/kg (given)

Filgrastim concentration:

The medication vial is labeled 300 mcg/mL. This indicates there are 300 mcg of filgrastim in every 1 mL of solution.

We need to find the volume (mL) containing the prescribed dose (based on weight) of filgrastim (5 mcg/kg) considering the concentration (300 mcg/mL) in the vial.

Total filgrastim dose (mcg): Dose (mcg/kg) x Client weight (kg)

Total filgrastim dose (mcg): 5 mcg/kg * 80 kg

Total filgrastim dose (mcg): 400 mcg

Volume to administer (mL): Total dose (mcg) / Concentration (mcg/mL)

Volume to administer (mL): 400 mcg / 300 mcg/mL

Volume to administer (mL) = 1.33 mL (round to nearest tenth)

Therefore, the nurse should administer approximately 1.3 mL of filgrastim subcutaneously.
