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 ["3"]

Explanation

To calculate the dose of calcitonin for a client who weighs 165 lb, the nurse needs to convert the weight to kilograms first.

One kilogram is equal to 2.2 lb, so the client's weight in kilograms is 165 / 2.2 = 75 kg.

The prescribed dose is 8 units/kg, so the total dose is 8 x 75 = 600 units.

The available concentration is 200 units/mL, so the volume to administer is 600 / 200 = 3 mL.

The nurse should administer 3 mL of calcitonin IM to the client.

Correct Answer is ["4"]

Explanation

To calculate the dose of mycostatin oral suspension, the nurse needs to divide the prescribed amount of units by the concentration of units per mL.

In this case, the nurse should divide 400,000 units by 100,000 units/mL, which gives 4 mL.

The nurse should administer 4 mL of mycostatin oral suspension every 6 hours as ordered.
