Morphine sulfate 7.5 mg subcutaneously every 4 hours as needed is ordered for a child weighing 84 lb.

The recommended maximum dose for a child is 0.1 to 0.2 mg/kg/dose.

How many milliliters will you administer for one dosage?

The child's weight should be converted from pounds to kilograms. Then, using the recommended dosage range of 0.1 to 0.2mg/kg/dose, we can determine that the child should receive between 3.81mg to 7.62mg of morphine sulfate. This will equate to between 3.81ml to 7.62ml, assuming a concentration of 1mg/ml.

Explanation:

To calculate the dosage in milliliters we first need to convert the child's weight from pounds to kilograms. There are about 2.20462 pounds in a kilogram. Hence, 84 lbs is approximately 38.1kg (84 divided by 2.20462).

As per the recommended dosage, given as 0.1 to 0.2mg/kg/dose, the child's dosage would fall between 3.81mg (38.1kg times 0.1) and 7.62mg (38.1kg times 0.2).

Considering the ordered morphine sulfate is 7.5mg and assuming it is in a liquid form with a concentration of 1 mg/ml (as the question does not specify), the number of milliliters to be administered would be the same as the required dose in mg. Hence, for a dose between 3.81mg and 7.62mg, we would administer between 3.81mL to 7.62mL. Please note that you should always follow the specific instructions of a healthcare professional.
