ATI PN Dosage Calculations. Adult medical surgical proctored assessment 3.1 ( 25 Questions)
A nurse is preparing to administer ampicillin/sulbactam 0.175 g IM to a client. The amount available is ampicillin/sulbactam powder 3 g. After reconstitution, the concentration available is ampicillin/sulbactam 375 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 dosage of ampicillin/sulbactam, the nurse needs to use the following formula:
Dosage (mL) = Ordered dose (mg) / Available dose (mg/mL)
The ordered dose is 0.175 g, which is equivalent to 175 mg. The available dose is 375 mg/mL. Plugging these values into the formula, we get:
Dosage (mL) = 175 / 375
Simplifying, we get:
Dosage (mL) = 0.4667
Rounding to the nearest tenth, the final answer is:
Dosage (mL) = 0.5
Therefore, the nurse should administer 0.5 mL of ampicillin/sulbactam to the client.
