NURS 3100 Exam 1 Practice

When reviewing drugs in a drug reference, what similarity should the nurse identify in drugs from the same class?

1. They have similar availability

2. They have similar mechanisms of action

3. They are administered by the same route

4. They have the same half-life

The correct answer is: They have similar mechanisms of action

When reviewing drugs in a drug reference, it is crucial for the nurse to identify the similarity that drugs from the same class have similar mechanisms of action. Drugs within the same class typically work in a similar way to produce their therapeutic effects. Understanding the mechanisms of action of drugs in the same class helps nurses anticipate potential side effects, interactions, and effectiveness of the medications. This knowledge is essential for safe medication administration and patient education. Options A, C, and D do not necessarily apply to drugs from the same class. Drugs in the same class may have different availability, be administered through different routes, and have varying half-lives. Therefore, the most important similarity to identify when reviewing drugs from the same class is their similar mechanisms of action.
