A nurse is preparing to administer midazolam 7 mg IM 30 min prior to a procedure. Available is midazolam injection 5 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.)

Calculation: Identify the desired dose. Desired dose = 7 mg. Identify the available concentration. Available concentration = 5 mg/mL. Calculate the volume to administer. Volume (mL) = Desired dose (mg) / Available concentration (mg/mL) = 7 mg / 5 mg/mL = 1.4 mL. Rounded to the nearest tenth: 1.4.
