Medical-Surgical Nursing - Cardiovascular MCQs with Answers

Answer: A. Coronary artery

Renal artery: This artery is responsible for supplying blood to the kidneys and has no direct role in myocardial infarction, which affects the heart.
Celiac artery: The celiac artery supplies blood to the stomach, liver, spleen, and other abdominal organs, making it unrelated to myocardial infarction.
Coronary artery: This is the correct answer. Coronary arteries provide oxygenated blood to the heart muscle, and a blockage in these arteries leads to myocardial infarction (heart attack) by depriving the
heart tissue of oxygen.
Hepatic artery: This artery supplies blood to the liver and plays no role in myocardial infarction, which involves the coronary arteries.

Answer: A. Cardiogenic trauma

Cardiogenic trauma: Cardiogenic trauma occurs when the heart muscle is damaged, often due to myocardial infarction (MI) or severe dysrhythmias, leading to reduced cardiac output and impaired
circulation.
Hypovolemic trauma: Hypovolemic trauma is caused by significant blood or fluid loss, such as in hemorrhage, and is unrelated to heart muscle damage.
Neurogenic trauma: Neurogenic trauma occurs due to damage to the nervous system, often leading to loss of vascular tone, but it is not associated with cardiac dysfunction.
Septic trauma: Septic trauma results from severe infections causing systemic inflammation, but it does not involve direct damage to the heart muscle.
