A nurse is preparing to administer ketorolac 30 mg IM for a loading dose. Available is ketorolac injection 15 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["2"]
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.

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.

Correct Answer is ["0.5"]
Explanation
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.
