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.)

Answer and Explanation

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 ["D","E"]

Explanation

A. Administer the medication twice daily. - No, the prescription states 50 mg PO TID (three times a day), not twice daily.

B. Administer the medication as needed for pain. - No, the prescription specifies a scheduled regimen, not PRN (as needed).

C. Administer the medication 2 hours after meals. - No, the prescription advises taking it with food, not after meals.

D. Administer a loading dose of 100 mg PO. - Yes, the initial dose is 100 mg PO now.

E. Administer the medication with a snack. - Yes, the prescription advises taking it with food, so administering it with a snack aligns with this instruction.

Correct Answer is ["12"]

Explanation

To calculate the dose of phenytoin oral suspension for a client with a seizure disorder, the nurse needs to use the following formula:

Dose (mL) = Ordered dose (mg) / Concentration (mg/mL)

In this case, the ordered dose is 300 mg and the concentration is 125 mg/5 mL. Therefore, the dose in mL is:

Dose (mL) = 300 mg / (125 mg/5 mL)

Dose (mL) = 300 mg x (5 mL/125 mg)

Dose (mL) = 12 mL

The nurse should round the answer to the nearest whole number, which is 12 mL. The nurse should administer 12 mL of phenytoin oral suspension every 12 hours to the client.
