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?
Answer
Final Answer: The client should be given approximately \(\boxed{2.17}\) milliliters of Demerol.
Step 1 ：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.
Step 2 ：The question is asking for a conversion of milligrams of Demerol to milliliters. We know that 60 milligrams of Demerol is equivalent to 2 milliliters. We need to find out how many milliliters is equivalent to 65 milligrams. This is a simple ratio problem that can be solved by setting up a proportion and solving for the unknown.
Step 3 ：Let's denote the amount of milligrams ordered as \(mg_{ordered}\) and the amount of milligrams per milliliter as \(mg_{per ml}\). We have \(mg_{ordered} = 65\) and \(mg_{per ml} = 30.0\).
Step 4 ：We can calculate the amount of milliliters to give, \(ml_{to give}\), by dividing the amount of milligrams ordered by the amount of milligrams per milliliter. This gives us \(ml_{to give} = \frac{mg_{ordered}}{mg_{per ml}} = \frac{65}{30.0} = 2.1666666666666665\).
Step 5 ：Rounding to two decimal places, we find that 65 milligrams of Demerol is equivalent to approximately 2.17 milliliters. This is the amount that should be given to the client.
Step 6 ：Final Answer: The client should be given approximately \(\boxed{2.17}\) milliliters of Demerol.
