Question

Order: Demerol 20mg IM q \( 3 \mathrm{hrs} \) prn pain. Available: Demerol \( 50 \mathrm{mg} / \mathrm{ml} \). How many \( \mathrm{ml} \) of the medication will you give? Order: Calcitonin \( 2.5 \mat

Answer 1

To calculate the amount of Demerol in ml to be given, divide the order in mg by the available strength in mg/ml.

Step-by-step explanation:

To determine how many milliliters (ml) of Demerol will be given, we need to calculate the dosage. The order is for Demerol 20mg IM q 3 hrs prn pain, and the medication available is Demerol 50mg/ml. We can use the formula:

Dosage (ml) = Order (mg) / Available (mg/ml)

Plugging in the values, we get:

Dosage (ml) = 20mg / 50mg/ml = 0.4 ml

Therefore, 0.4 ml of Demerol will be administered.
