Solve the following parenteral dosage problem. The client is in pain. The physician's order is for Demerol 65 milligrams every 4 hours IM as needed for pain. The Demerol label reads 60 milligrams in 2 milliliter. How many milliliters should be given?

Step 1 ：The problem is asking for the volume of Demerol to be administered to the patient. To find this, we need to set up a proportion to compare the dosage ordered by the physician (65 milligrams) to the dosage provided on the Demerol label (60 milligrams in 2 milliliters).

Step 2 ：The proportion can be set up as follows: \(\frac{65 \text{ milligrams}}{x \text{ milliliters}} = \frac{60 \text{ milligrams}}{2 \text{ milliliters}}\)

Step 3 ：We can solve this proportion for x to find the volume of Demerol to be administered.

Step 4 ：The volume of Demerol to be administered is approximately 2.17 milliliters.

Step 5 ：Final Answer: The volume of Demerol to be administered should be approximately \(\boxed{2.17}\) milliliters.
