Which of the following is NOT a common red flag symptom listed?

• A. Night pain
• B. Weight loss
• C. Fever
• D. Nausea

Answer: (D)

In screening for serious underlying conditions, red flag symptoms point to possible infections, cancer, or systemic disease. Night pain, unexplained weight loss, and fever are classic red flags because they suggest ongoing pathology needing medical evaluation. Nausea, on the other hand, is not by itself a red flag for serious pathology in this context; it’s common and often due to benign causes. So the symptom that is not a common red flag is nausea. If nausea appears with other red flags or alarming signs, it would warrant further assessment.
