A nurse is preparing to administer hydrocortisone 60 mg IV bolus to a child. The amount available is hydrocortisone 100 mg powder. Reconstituting with 2 mL of bacteriostatic water yields hydrocortisone 50 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if applicable. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["1.2"]

To calculate this, divide the dose of hydrocortisone in mg by the concentration of the reconstituted hydrocortisone to find the volume to administer: 60 mg / (50 mg/mL) = 1.2 mL.

Correct Answer is ["1.2"]

Explanation

Step 1 is to convert the child’s weight from pounds to kilograms since the dosage of morphine is prescribed in mg/kg. We know that 1 kg is approximately equal to 2.2 lb. So, the child’s weight in kg is:

51 lb ÷ 2.2 = 23.18 kg

Step 2 is to calculate the total amount of morphine the child should receive per dose. The doctor ordered 0.1 mg of morphine per kg of body weight. So, the total amount of morphine per dose is:

0.1 mg/kg × 23.18 kg = 2.318 mg

Step 3 is to calculate the volume of morphine injection to be administered. We know that the available morphine injection has a concentration of 2 mg/mL. So, the volume in mL is:

2.318 mg ÷ (2 mg/mL) = 1.159 mL

Rounding this to the nearest tenth gives 1.2 mL. So, the nurse should administer 1.2 mL of morphine injection per dose.

So, the correct answer is 1.2 mL.

Correct Answer is ["1.5"]

Explanation

7.5 mL is equivalent to 1.5 teaspoons.

To calculate this, use the conversion factor that 1 tsp is equivalent to 5 mL. So, 7.5 mL * (1 tsp / 5 mL) = 1.5 tsp.
