20. Which of the following statements best summarizes the warning label on a bottle of over-the-counter cold medicine?

Answer: D

Explanation:

If you have a respiratory problem, take this medication only if directed by a doctor.

The warning label advises that individuals with long-term respiratory issues, such as emphysema or chronic bronchitis, should not use the medication without a doctor's direction. This guidance emphasizes the importance of consulting a healthcare professional before use in such cases.

A) This medication is intended to treat long-term respiratory illnesses.

This statement is incorrect as the extract specifies that the medication is meant for mild respiratory infections and warns against its use for long-term respiratory problems without a doctor's guidance.

B) Anyone taking this medication must have a doctor's recommendation.

This option is misleading. While the label indicates that those with long-term respiratory problems should consult a doctor, it does not state that everyone taking the medication must have a doctor's recommendation.

C) Patients who have a mild respiratory infection should consult a doctor.

This statement does not accurately summarize the warning label. The label does not suggest that patients with mild respiratory infections need to consult a doctor; instead, it focuses on those with long-term respiratory issues.

D) If you have a respiratory problem, take this medication only if directed by a doctor.

This option correctly summarizes the warning on the label. It highlights the necessity of medical direction for individuals with pre-existing respiratory conditions before using the medication.

Conclusion

Option D is the most accurate representation of the warning label's intent, emphasizing that those with respiratory problems should only take the medication if directed by a healthcare professional. The other options either misinterpret the label's message or incorrectly generalize its guidance, making them unsuitable summaries of the warning.
