A client presents with sharp chest pain and palpitations. The most likely diagnosis is?

• A. Pulmonary embolism
• B. Myocardial infarction
• C. Pneumothorax
• D. Aortic dissection

Answer: (B)

The key idea is recognizing acute coronary syndrome as the most likely cause of chest pain with palpitations. Chest pain from a myocardial infarction is often described as pressure or squeezing in the chest that may radiate to the jaw, neck, shoulder, or arm, and the heart’s lack of oxygen can trigger electrical instability leading to palpitations. Among the options, the others have features that point to different issues: pulmonary embolism typically presents with sudden pleuritic chest pain and notable shortness of breath; pneumothorax causes sudden sharp chest pain with unilateral breath sounds changes; aortic dissection presents as sudden, severe tearing chest pain radiating to the back, often with blood pressure differences between arms. Thus, the pattern of chest pain with accompanying palpitations most aligns with myocardial infarction. Immediate priorities include cardiac monitoring, obtaining an ECG and troponin, and giving aspirin if not contraindicated, with rapid escalation to reperfusion therapy as indicated.
