- lower extremity edema
- uncomfortable feeling of pressure in the chest
Number 3 is correct.
Rationale: An uncomfortable feeling of pressure, squeezing, fullness, or pain in the center of the chest is the predominant symptom of an MI in women. Palpitations indicate an arrhythmia. Edema in the lower extremities is a later sign of cardiac failure. A feeling of nausea is less common when experiencing an MI.
