A patient is prescribed morphine sulfate 5 mg IV every 4 hours as needed for a pain level greater than 7 on a scale of 0-10. Morphine is available in 8 mg/mL vials. How many mL will the nurse give for the correct dose? Round to the nearest hundredth. Use a preceding zero if necessary. Do not use trailing zeros.

To calculate the correct dose: Identify the prescribed dose: 5 mg Identify the concentration of the available morphine: 8 mg/mL Calculate the volume to be administered: Volume (mL) = Prescribed dose (mg) ÷ Concentration (mg/mL) Volume (mL) = 5 mg ÷ 8 mg/mL Volume (mL) = 0.625 mL The nurse will give 0.63 mL (rounded to the nearest hundredth) for the correct dose.
