NURS 3100 Exam 1 Practice

What is a common characteristic of drugs in the same class?

1. They have the same molecular weight

2. They have the same active ingredients

3. They have similar mechanisms of action

4. They are metabolized in the same way

The correct answer is: They have similar mechanisms of action

Drugs in the same class typically have similar mechanisms of action. This means that they work in the body in a similar way to produce their therapeutic effects. While drugs in the same class may share some similarities, such as chemical structure or active ingredients, what distinguishes them as being in the same class is primarily their mechanism of action. This allows healthcare providers to predict how a drug will work based on its class and to select appropriate medications for specific conditions based on their similar mechanisms of action.
