A prescription reads morphine sulfate, 8 mg stat. The medication ampule reads morphine sulfate, 10mg/ml. The nurse prepares how many milliliters (mL) to administer the correct dose. Round to the nearest tenth.
The Correct Answer is ["0.8"]
To administer the correct dose of morphine sulfate, which is prescribed at 8 mg stat, and given that the medication ampule concentration is 10 mg/mL, the nurse would need to calculate the volume of medication to administer. The calculation is based on the formula: Volume (mL) = Dose (mg) / Concentration (mg/mL). Therefore, for an 8 mg dose, the nurse would prepare 0.8 mL of morphine sulfate to administer, rounding to the nearest tenth.
