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.)
The Correct Answer is ["0.5"]
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.

Correct Answer is ["3"]
Explanation
Determine the total daily dosage:
The client is prescribed 30 mg of furosemide.
Calculate the dosage per dose:
The medication is to be administered in a single dose.
Dosage per dose is 30 mg.
Determine the volume per dose:
The furosemide injection contains 10 mg per mL.
The nurse needs to administer 30 mg per dose.
Divide 30 mg / 10 mg per mL = 3 mL per dose.
Correct Answer is ["133"]
Explanation
Calculate the infusion rate:800 mL / 6 hours = 133.33 mL/hr
Round to the nearest whole number:133.33 mL/hr rounds to 133 mL/hr
