Route
Brand name
Weight of child
Correct Answer : D
A. Frequency - This is essential to know how often the medication should be administered.
B. Strength of solution - The strength of the solution is crucial for calculating the correct dose based on the prescribed amount per kilogram of the child's weight.
C. Route - Knowing the route of administration is important to ensure the medication is given correctly. In this case, it's specified as a solution, suggesting it might be oral.
D. Brand name - While brand names can be relevant for certain medications, the generic name (dexamethasone, in this case) is usually sufficient for understanding and administering the medication.

Correct Answer is ["0.7"]
Explanation
To calculate the dosage of diphenhydramine injection, the nurse should use the formula D/H x Q, where D is the desired dose, H is the dose on hand, and Q is the quantity. In this case, D is 35 mg, H is 50 mg/mL, and Q is 1 mL.
Plugging these values into the formula, we get:
35 mg / 50 mg/mL x 1 mL = 0.7 mL
Therefore, the nurse should administer 0.7 mL of diphenhydramine injection.
Correct Answer is ["3"]
Explanation
To calculate the number of tablets that the nurse should administer per dose, the nurse needs to convert the prescribed dose of calcium carbonate from grams to milligrams and then divide it by the strength of the available tablets. The formula is:
Prescribed dose (mg) / Tablet strength (mg) = Number of tablets
The prescribed dose of calcium carbonate is 3.9 g PO daily in equally divided doses every 12 hr.
To convert grams to milligrams, multiply by 1000.
Therefore, 3.9 g = 3900 mg.
Since the doses are equally divided every 12 hr, the nurse needs to divide the daily dose by 2 to get the dose per 12 hr. Therefore, 3900 mg / 2 = 1950 mg.
The available tablets have a strength of 650 mg each.
To find the number of tablets per dose, divide the dose per 12 hr by the tablet strength.
Therefore, 1950 mg / 650 mg = 3 tablets.
