NAPLEX (North American Pharmacist Licensure Examination) Practice Exam

What can physical incompatibilities occur between?

1. Drug and sunlight

2. Drug and food

3. Drug and container

4. Drug and doctor's prescription

The correct answer is: Drug and container

Physical incompatibilities can occur between a drug and its container when the container is not compatible with the drug's chemical composition. This can happen if the container is made of a material that reacts with the drug, causing it to degrade or change its effectiveness. This is why it's important to store medications in the appropriate container, such as a glass or plastic bottle, and not transfer them to a different container. In contrast, while drug incompatibilities can also occur with sunlight, food, and doctor's prescriptions, these are not considered physical incompatibilities as they do not involve the drug's container.
