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.)

Answer and Explanation

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.

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 ["300"]

Explanation

One way to calculate the IV pump rate is to divide the total volume of fluid by the total time in hours.

In this case, the client needs to receive 1,800 mL of 0.9% sodium chloride over 6 hours.

Therefore, the IV pump rate should be 1,800 mL / 6 hr = 300 mL/hr.

The nurse should ensure the IV pump is set to deliver 300 mL/hr of 0.9% sodium chloride to the client.
