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 ["2"]

Explanation

To give a loading dose of ketorolac 30 mg IM, the nurse needs to calculate the volume of the injection solution.

The solution has a concentration of 15 mg/mL, which means that every 1 mL contains 15 mg of ketorolac.

To find the volume, the nurse can use the formula: volume = dose / concentration. Plugging in the values, we get: volume = 30 mg / 15 mg/mL = 2 mL.

Therefore, the nurse should administer 2 mL of ketorolac injection for a loading dose.

Correct Answer is ["38"]

Explanation

To calculate the IV flow rate in gtt/min, the nurse needs to use the following formula: IV flow rate (gtt/min) = Volume (mL) x Drop factor (gtt/mL) / Time (min).

In this case, the volume is 150 mL, the drop factor is 15 gtt/mL, and the time is 60 min.

Plugging these values into the formula, we get: IV flow rate (gtt/min) = 150 x 15 / 60.

Simplifying, we get: IV flow rate (gtt/min) = 37.5.

Therefore, the nurse should set the IV flow rate to deliver 38 gtt/min.
