Penicillin G procaine 240,000 units Intramuscularly (IM) is prescribed for a 4-year-old child who has a streptococcal respiratory infection. The medication vial is labeled, *1,200,000 units/2 mL" How many mL should the nurse administer? (Enter numeric value only. If rounding is required, round to the nearest tenth.)

Answer and Explanation

The Correct Answer is ["0.4"]

Here's the breakdown of the calculation:

The medication vial is labeled 1,200,000 units/2 mL, which means there are 1,200,000 units of penicillin G per every 2 mL of the medication.

We need to find out how many mL are needed to administer the prescribed dose of 240,000 units.

To do this, we can divide the desired dose (240,000 units) by the concentration of the medication (units per mL).

Calculation:

Dose per mL = 1,200,000 units / 2 mL = 600,000 units/mL

Desired dose / Dose per mL = 240,000 units / 600,000 units/mL = 0.4 mL

Rounding to the nearest tenth, the nurse should administer 0.4 mL of Penicillin G procaine.

Correct Answer is ["50"]

Explanation

First, let’s calculate the current infusion rate in mL/hour.

The IV solution contains 20,000 units of heparin in 500 mL, so the concentration is:

Concentration = Totalunits/ Totalvolume = 20,000units /500mL = 40units/mL

The client is currently receiving 1,800 units/hour. At a concentration of 40 units/mL, this dosage is equivalent to:

Currentrate = Dose/ Concentration = 1,800units/hour / 40units/mL = 45mL/hour

The healthcare provider prescribed an increase of 5 mL/hour in the IV rate. Therefore, the new rate should be:

Newrate = Currentrate + Increase = 45mL/hour + 5mL/hour = 50mL/hour

So, the nurse should set the infusion pump to deliver 50 mL/hour. If rounding is required, this is already rounded to the nearest whole number.

Correct Answer is ["15"]

Explanation

First, we need to convert the child’s weight from pounds to kilograms since the dosage is prescribed in mg/kg. We know that 1 kg is approximately 2.20462 pounds. So,

Weightinkg = Weightinpounds / 2.20462 = 2.2046266 ≈ 29.94kg

The prescribed dosage is 80 mg/kg/day, so the total daily dosage in mg would be:

Dailydosageinmg = Dosageperkg × Weightinkg = 80mg/kg × 29.94kg ≈ 2395.2mg

The medication is to be administered in divided doses every 12 hours, so the dosage per dose in mg would be:

Dosageperdoseinmg = Dailydosageinmg/2 = 2395.2mg/2 ≈ 1197.6mg

The medication is available in a concentration of 400 mg/5 mL. Therefore, the volume to be administered per dose in mL would be:

VolumeinmL = Dosageperdoseinmg / Concentrationinmg/mL = 1197.6mg / 80mg/mL ≈ 14.97mL

So, the nurse should administer approximately 15 mL of Amoxicillin for Oral Suspension, USP per dose. Please note that this is a rounded value and the exact volume would be 14.97 mL.
