A nurse is preparing to administer morphine 7.5 mg subcutaneous. Available is morphine injection 10 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest hundredth. Use a leading zero if it applies. Do not use a trailing zero.)

To calculate the dosage of morphine, the nurse needs to use the formula D/H x V, where D is the desired dose, H is the dose on hand, and V is the volume on hand. In this case, D is 7.5 mg, H is 10 mg/mL, and V is 1 mL. Plugging these values into the formula, we get: 7.5 mg / 10 mg/mL x 1 mL = 0.75 mL Therefore, the final answer is: 0.75 mL The nurse should administer 0.75 mL of morphine subcutaneous to the patient.
