A nurse is preparing to administer morphine 30 mg PO to a client who reports pain. Available is morphine solution 20 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

To calculate the required mL of morphine solution needed to administer 30 mg of morphine orally (PO), you can use the following formula: Volume (in mL) = Amount (in mg) / Concentration (in mg/mL) In this case, the amount of morphine is 30 mg, and the concentration of the morphine solution is 20 mg/mL. Volume (in mL) = 30 mg / 20 mg/mL Volume (in mL) = 1.5 mL Therefore, the nurse should administer 1.5 mL of the morphine solution to deliver 30 mg of morphine to the client orally.
