Which of the following is not a sign of a possible heart attack?

• A. Chest pain or pressure.
• B. Bleeding from the mouth.
• C. Shortness of breath.
• D. Nausea.

Answer: (B)

Signs of a possible heart attack come from reduced blood flow to the heart. The most common signals are chest pain or pressure that may feel like tightness or heaviness, shortness of breath, and nausea or lightheadedness (often with sweating). Bleeding from the mouth does not fit this pattern; it points to mouth injury, dental problems, or another issue, not a heart attack. Because heart attack symptoms can vary, people might also notice pain or discomfort in the jaw, neck, back, or arms, but not bleeding from the mouth. If heart attack is suspected, seek emergency medical help immediately and provide supportive care while waiting.
