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

Correct Answer is ["80"]
Explanation
To calculate the infusion rate for gentamicin, the nurse should use the following formula:
Infusion rate (mL/hr) = Volume (mL) / Time (hr)
Plugging in the given values, we get:
Infusion rate (mL/hr) = 100 mL / (75 min / 60 min/hr)
Simplifying, we get:
Infusion rate (mL/hr) = 100 mL / 1.25 hr
Dividing, we get:
Infusion rate (mL/hr) = 80 mL/hr
Therefore, the nurse should ensure the IV pump is set to deliver 80 mL/hr of gentamicin.
Correct Answer is ["3"]
Explanation
To calculate the correct dosage of furosemide for an intramuscular injection, the nurse needs to divide the prescribed amount by the concentration of the drug.
In this case, the prescribed amount is 30 mg and the concentration is 10 mg/mL.
Therefore, the nurse should divide 30 mg by 10 mg/mL and get 3 mL.
