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 ["125"]
Explanation
Determine the total volume to be administered:
The client is to receive 500 mL of lactated Ringer's IV.
Calculate the time to administer the volume:
The medication is to be administered over 4 hours.
Calculate the flow rate:
To find the flow rate in mL/hr, we can divide the total volume by the time:
Flow rate (mL/hr) = Total volume (mL) / Time (hr)
Flow rate = 500 mL / 4 hr= 125 mL/hr
Correct Answer is ["0.71"]
Explanation
Determine the total dosage:
The client is prescribed 250 mg of ceftriaxone.
Calculate the volume per dose:
The ceftriaxone solution contains 350 mg per mL.
The nurse needs to administer 250 mg per dose.
To find the volume per dose:
350 mg / 1 mL = 250 mg / x mL
350x = 250
Dividing both sides by 350, we get:
x = 0.714 mL
Round the answer to the nearest hundredth:
Rounding 0.714 to the nearest hundredth gives us 0.71 mL.
