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 ["31"]
Explanation
Determine the flow rate in mL/min:
The desired flow rate is 125 mL/hr.
There are 60 minutes in an hour.
Flow rate in mL/min: 125 mL/hr ÷ 60 min/hr = 2.0833 mL/min.
Calculate the drip rate in gtt/min:
The drip factor of the tubing is 15 gtt/mL.
This means that for every 1 mL, there are 15 drops.
To find the drip rate in gtt/min:
Drip rate (gtt/min) = Flow rate (mL/min) × Drip factor (gtt/mL)
Drip rate = 2.0833 mL/min × 15 gtt/mL
Calculating the drip rate:
Drip rate = 31.25 gtt/min
Round the answer to the nearest whole number:
Rounding 31.25 to the nearest whole number gives us 31 gtt/min.
Correct Answer is ["0.5"]
Explanation
Determine the total dosage:
The client is prescribed 25 mg of promethazine.
Calculate the volume per dose:
The promethazine solution contains 50 mg per mL.
The nurse needs to administer 25 mg per dose.
To find the volume per dose:
50 mg / 1 mL = 25 mg / x mL
50x = 25
Dividing both sides by 50, we get:
x = 0.5 mL
