A nurse is preparing to administer midazolam 0.07 mg/kg IM to a client who weighs 50 kg. Available is midazolam 5 mg/mL. How many mLs 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 dose of midazolam to administer, we first find the total dose needed by multiplying the client's weight (50 kg) by the dose prescribed (0.07 mg/kg), which equals 3.5 mg. To convert this to mL, we divide by the concentration of midazolam (5 mg/mL), resulting in 0.7 mL. Therefore, the correct answer is B. Choices A, C, D, and other options are incorrect as they do not reflect the accurate calculation based on the client's weight, prescribed dose, and medication concentration.
