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.

Correct Answer is A
Explanation
A. Shake the suspension well before each administration.
The medication label specifically states, "IMPORTANT: SHAKE WELL BEFORE EACH USE," and "THIS PRODUCT MUST BE SHAKEN WELL ESPECIALLY PRIOR TO INITIAL USE." This indicates the necessity of shaking the suspension before administration to ensure proper mixing of the medication.
B. Dilute the suspension with 38 mL water prior to initial use.
There is no indication on the label to dilute the suspension with water. The label emphasizes shaking well before use, but dilution is not mentioned.
C. Store the suspension in the refrigerator.
The storage instructions on the label state, "Store at 20° to 25°C (68° to 77° F) see USP controlled room temperature." Refrigeration is not mentioned, and it is not recommended to deviate from the specified storage conditions.
D. Discard the suspension 14 days after opening the bottle.
The label does not provide specific information about the shelf life after opening. Therefore, it is essential to follow the specific instructions on the label or refer to the package insert for complete prescribing information regarding the expiration or discard date after opening. The information on the label does not specify a 14-day limit.
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.
