26 A cardiac stress test shows ST-segment depression in a 60-year-old male
during exercise. What is the most likely condition?
A Non-ST elevation myocardial infarction B Stable angina C Prinzmetal angina D Pericarditis Explanation: ST-segment depression during exercise indicates myocardial ischemia, typically seen in stable angina.

most likely associated with mitral regurgitation?
A Systolic ejection murmur B Holosystolic murmur C Diastolic murmur D Continuous murmur Explanation: A holosystolic murmur is characteristic of mitral regurgitation due to the backflow of blood from the left ventricle to the left atrium.
