A nurse is preparing to administer penicillin G potassium 1,000,000 units intermittent IV bolus. The label on the vial indicates to reconstitute with 50 ml of sterile water to make penicillin G potassium 100,000 units/ml. How many ml, should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Answer and Explanation

The Correct Answer is ["10"]

To determine how many milliliters (mL) of the reconstituted penicillin G potassium to administer, you can use the following calculation:

Given:

  • Reconstituted concentration: 100,000 units/mL
  • Total dose to be administered: 1,000,000 units

Now, use the formula:

Volume (mL) = Total dose (units) / Concentration (units/mL)

Volume (mL) = 1,000,000 units / 100,000 units/mL

Volume (mL) = 10 mL

So, the nurse should administer 10 mL of the reconstituted penicillin G potassium.

Correct Answer is ["1.2"]

Explanation

To calculate the mL of phenobarbital to administer per dose, you can use the following steps:

Convert the client's weight from pounds to kilograms. There are approximately 2.2 pounds in 1 kilogram.
Weight in kg = 165 lb / 2.2 lb/kg ≈ 75 kg

Calculate the total daily dose based on the client's weight and the prescribed dose per kilogram:
Total daily dose = 2 mg/kg/day × 75 kg ≈ 150 mg/day

Since the dose is divided into two equal doses per day, calculate the dose per dose:
Dose per dose = Total daily dose / 2 = 150 mg / 2 = 75 mg

Now, you need to find out how many mL of phenobarbital 65 mg/mL corresponds to a dose of 75 mg:
Volume (mL) = Dose (mg) / Concentration (mg/mL) = 75 mg / 65 mg/mL ≈ 1.1538 mL

Rounded to the nearest tenth, the nurse should administer approximately 1.2 mL of phenobarbital per dose.

Correct Answer is ["68"]

Explanation

To calculate the mL of acetaminophen to administer, follow these steps:
Convert the client's weight from pounds (lb) to kilograms (kg):
Client's weight in kg = Client's weight in lb / 2.2 Client's weight in kg = 99 lb / 2.2 ≈ 45 kg

Determine the total dosage required based on the client's weight:
Total dosage = Client's weight in kg × Dosage (mg/kg) Total dosage = 45 kg × 15 mg/kg = 675 mg

Determine the mL to administer based on the available concentration:
Concentration (mg/mL) = 1,000 mg / 100 mL = 10 mg/mL

Calculate the mL to administer:
mL to administer = Total dosage (mg) / Concentration (mg/mL) mL to administer = 675 mg / 10 mg/mL = 67.5 mL

Round the answer to the nearest whole number:
The nurse should administer 68 mL of acetaminophen
