    A contraindication is a specific situation where a drug should not be used because it may cause harm.

  4. What is the difference between a side effect and an adverse reaction?

    Answer: Side effects are expected; adverse reactions are harmful and unexpected

    Side effects are predictable secondary effects, while adverse reactions are unexpected harmful responses to medication.

  5. Why is it important to check for drug allergies before administration?
