Neuro Midterm 4 Practice

. A 45-year-old man complains of sharp stabbing pain in the chest, cough and shortness of breath of recent origin. The physician orders a CT scan of the chest after observing that the X-ray chest did not reveal any finding. CT scan demonstrates an aneurysm that has dissected the wall of the descending thoracic aorta. Which structure in the CT showed the aneurysmal defect? A/B/C/D/E E

c. Temporal artery d. Carotid or femoral artery Overwhelming infection and resulting vasodilation can lead to the following type of shock OAnaphylactic O Cardiogenic Hypovolemic

IV. Label the following parts of a blood vessel: А: D B: C: D: E: F: ARTERY 7. V. Describe the following relationships/correlations {Example: one goes pressufe inarases, Ho bressure dearease, fig 2) Resistance and Blood Flow = fesistone increases, 1) Pressure and Blood Flow %3D

7. An 84-year-old man is brought to the emergency department 30 minutes after an episode of syncope. Transthoracic echocardiography shows a 4-cm myxoma occupying the majority of the left atrium. The tumor will be excised using a robotically assisted operation via an oblique right atriotomy and transection of the interatrial septum. When making the incision into the left atrium to remove the myxoma, which of the following regions of the interatrial septum should be avoided in order to prevent injury to the cardiac conduction system? A) Crista terminalis B) Fossa ovalis region C) Posteroinferior region above the opening of the coronary sinus D) Superoanterior region above the limbus of the fossa ovalis E) Superoposterior region posterior to the fossa ovalis

Background 1: A patient you are seeing has blood in their sputum, Low blood pressure (hypotension) and elevated heart rate. This stems from a condition called mitral regurgitation (sometimes called mitral insufficiency). Describe the normal purpose of the heart valves, both the Atrioventricular valves and semilunar valves individually. NEXT, describe mitral regurgitation.
