Which symptom would NOT typically indicate a medical emergency?

A persistent cough may not typically indicate a medical emergency because it can often be a symptom of various non-emergency conditions, such as a common cold or mild respiratory infection. In many cases, a cough can be managed at home or with outpatient care and does not necessarily require immediate medical attention.

In contrast, severe chest pain, loss of consciousness, and difficulty breathing are symptoms that usually suggest a more serious underlying issue. For instance, severe chest pain could indicate a heart attack, which is a critical condition requiring urgent care. Loss of consciousness may signal a neurological or cardiovascular problem that needs immediate evaluation. Difficulty breathing is also a significant warning sign that can arise from various severe medical conditions, including asthma attacks, anaphylactic reactions, or respiratory distress, all of which necessitate prompt medical intervention.
