How many milliliters of morphine sulfate should be administered to achieve a dose of 10 mg if the concentration is 15 mg/mL?

To determine the correct volume of morphine sulfate needed to achieve a dose of 10 mg when the concentration is 15 mg/mL, one can use the formula:

Volume (mL) = Desired Dose (mg) / Concentration (mg/mL).

Substituting the values into the formula:

Volume (mL) = 10 mg / 15 mg/mL = 0.6667 mL.

This can be rounded to approximately 0.7 mL, which matches the answer choice. Therefore, administering 0.7 mL would provide the patient with the correct dosage of 10 mg of morphine sulfate given the concentration provided.
