ATI PN Management 2020 ( 86 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 volume (mL) that the nurse should administer, you can use the following formula:
Volume (mL)=Dose (g)/Concentration (g/mL)
In this case:
Volume=0.175 g/375 mg/mL
First, convert the dose to grams:
0.175g=175mg
Now calculate the volume:
Volume = 175mg/375 mg/mL
Volume=0.4667mL
Rounded to the nearest tenth, the nurse should administer approximately 0.5 mL of ampicillin/sulbactam for the 0.175 g IM dose.
