If the prescribed dose of morphine sulfate is 8 mg and the concentration is 10 mg/mL, how many mL will the nurse administer?

To determine how many mL the nurse will administer, you can use the concentration of the medication along with the prescribed dose. The concentration of the morphine sulfate is 10 mg/mL.

To find out how many mL are needed to achieve the prescribed dose of 8 mg, you can set up the following calculation:

1. Use the formula:

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

2. Substitute the known values into the formula:

Volume (mL) = 8 mg / 10 mg/mL

3. Performing the calculation gives:

Volume (mL) = 0.8 mL

This calculation reflects how much of the liquid medication needs to be drawn up into the syringe to deliver the exact dose required. Therefore, administering 0.8 mL of morphine sulfate will provide the patient with the prescribed dose of 8 mg. This illustrates an important concept in medication administration, emphasizing the need to accurately calculate dosages based on concentration.
