A nurse is preparing to administer ampicillin/sulbactam 0.175g IM to a client. The amount available is ampicillin/sulbactam 3 g. After reconstitution, the concentration available is ampicillin/sulbactam 375 mg/mL. How many mL should the nurse administer? (Round the answer the nearest tenth. Use leading zero if it applies. Do not use a trailing zero.)

Determine the total dosage: The client is prescribed 0.175 g of ampicillin/sulbactam. Convert the dosage to milligrams: There are 1000 milligrams in 1 gram. 0.175 g = 0.175 x 1000 = 175 mg. Calculate the volume per dose: The ampicillin/sulbactam solution contains 375 mg per mL. The nurse needs to administer 175 mg per dose. To find the volume per dose: 375 mg / 1 mL = 175 mg / x mL 375x = 175 Dividing both sides by 375, we get: x = 0.467 mL Round the answer to the nearest tenth: Rounding 0.467 to the nearest tenth gives us 0.5 mL.
