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 ["0.75"]
Explanation
To calculate the dosage of morphine, the nurse needs to use the formula D/H x V, where D is the desired dose, H is the dose on hand, and V is the volume on hand. In this case, D is 7.5 mg, H is 10 mg/mL, and V is 1 mL. Plugging these values into the formula, we get:
7.5 mg / 10 mg/mL x 1 mL = 0.75 mL
Therefore, the final answer is: 0.75 mL
The nurse should administer 0.75 mL of morphine subcutaneous to the patient.
Correct Answer is ["500"]
Explanation
To calculate the infusion rate for lactated Ringer's solution, the nurse should use the following formula: infusion rate (mL/hr) = volume (mL) / time (hr).
Since the volume is 250 mL and the time is 0.5 hr (30 min), the infusion rate is 250 / 0.5 = 500 mL/hr.
The nurse should set the IV pump to deliver 500 mL/hr of lactated Ringer's solution to the patient.
