Correct Answer is ["0.7"]

Explanation

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.
