The Correct Answer is A
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 ["0.5"]
Explanation
To calculate the correct dosage of promethazine for a client, the nurse needs to use the formula D/H x V, where D is the desired dose, H is the available dose, and V is the available volume. In this case, D is 25 mg, H is 50 mg, and V is 1 mL.
Plugging these values into the formula, we get:
25/50 x 1 = 0.5 mL
Therefore, the nurse should administer 0.5 mL of promethazine 50 mg/mL IM to the client.
Correct Answer is ["10"]
Explanation
To calculate the dose of amoxicillin oral suspension for a client, the nurse needs to use the following formula: Dose (mL) = Desired dose (mg) / Available dose (mg/mL) x Volume (mL).
In this case, the desired dose is 500 mg, the available dose is 250 mg/5 mL, and the volume is 5 mL.
Therefore, the dose (mL) = 500 mg / (250 mg/5 mL) x 5 mL = 10 mL.
The nurse should administer 10 mL of amoxicillin oral suspension to the client.
