A nurse is preparing to administer morphine 0.2 mg/kg IM to a child who weighs 77 lb. Available is morphine injection 10 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["0.7"]

To calculate the dosage of morphine for a child, the nurse needs to convert the child's weight from pounds to kilograms and then multiply it by the prescribed dose per kilogram. The nurse also needs to divide the resulting amount by the concentration of the morphine injection to get the volume to be administered. The formula is:

Volume (mL) = (Weight (kg) x Dose (mg/kg)) / Concentration (mg/mL)

In this case, the child weighs 77 lb, which is equivalent to 35 kg (77 / 2.2 = 35). The prescribed dose is 0.2 mg/kg and the concentration of the morphine injection is 10 mg/mL. Therefore, the volume to be administered is:

Volume (mL) = (35 x 0.2) / 10

Volume (mL) = 0.7

The nurse should round the answer to the nearest tenth, which is 0.7 mL.

Correct Answer is ["3"]

Explanation

To calculate the dosage of bumetanide, the nurse should divide the ordered dose by the available dose and multiply by one tablet.

In this case, the nurse should divide 1.5 mg by 0.5 mg and multiply by one tablet, which gives 3 tablets.

Therefore, the nurse should administer 3 tablets of bumetanide 0.5 mg PO daily.

Correct Answer is ["1"]

Explanation

This is a question that tests the nurse's ability to calculate drug dosages based on the client's weight and the drug concentration. To solve this problem, the nurse needs to follow these steps:

1. Convert the client's weight from pounds to kilograms by dividing by 2.2. 176 lb / 2.2 = 80 kg.

2. Multiply the client's weight in kilograms by the prescribed dose in micrograms per kilogram to get the total dose in micrograms. 80 kg x 50 mcg/kg = 4000 mcg.

3. Convert the total dose in micrograms to milligrams by dividing by 1000. 4000 mcg / 1000 = 4 mg.

4. Divide the total dose in milligrams by the drug concentration in milligrams per milliliter to get the volume in milliliters. 4 mg / 4 mg/mL = 1 mL.

5. Round the answer to the nearest whole number and add a leading zero if it applies. Do not use a trailing zero. The final answer is 1 mL.

Therefore, the nurse should administer 1 mL of lorazepam IM to the client.
