Florida State Paramedic Practice Exam

What condition is indicated by chest pain that is shearing or tearing in nature, radiating to the neck, and no pedal pulse?

1. Myocardial Infarction

2. Pulmonary Embolism

3. Aortic Aneurysm

4. Pneumothorax

The correct answer is: Aortic Aneurysm

The condition indicated by chest pain that is shearing or tearing in nature, radiating to the neck, and accompanied by the absence of a pedal pulse is consistent with an aortic aneurysm. This type of pain is often described as "tearing" because the aorta is under considerable pressure, and when there is a rupture or dissection, it causes severe and sudden pain that can radiate to areas such as the neck, back, or shoulders. The presence of no pedal pulse suggests a possible compromise in blood flow, which can occur when the aorta is dissecting and the blood is being diverted away from peripheral arteries. This can lead to ischemia in the lower extremities, further supporting the diagnosis of an aortic-related issue. The other conditions listed do not typically present with the combination of symptoms described in the question. For instance, myocardial infarction may cause chest pain, but it is generally more related to pressure or heaviness rather than a tearing sensation, and it does not typically cause a distinct loss of pedal pulses unless there are significant complications such as cardiogenic shock. Pulmonary embolism often causes pleuritic chest pain and shortness of breath rather than tearing pain, and pneumothorax produces different sensations and
