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.) ________ mL

Step 1 is to identify the ordered dose and the available concentration Ordered Dose: 7.5 mg Available Concentration: 10 mg / 1 mL Step 2 is to calculate the volume to administer in milliliters (mL) Volume = (Ordered Dose ÷ Available Dose) × Available Volume Volume = (7.5 ÷ 10) × 1 7.5 ÷ 10 = 0.75 0.75 × 1 = 0.75 Step 3 is to round to the nearest hundredth 0.75 = 0.75 Answer: 0.75
