The resistance against which the right ventricle must work to eject its volume is known as • Resting heart pressure • Systemic vascular pressure • Central venous pressure • Pulmonary vascular resistance - CORRECT ANSWER - Pulmonary Vascular Resistance
Rationale; This pressure represents a mean pressure in the systemic vasculature. The higher the resistance, the harder the heart has to work against it.
EXA: Colder temperatures will cause vasoconstriction; the heart
then has to pump harder to deliver blood through the narrowed vasculature. 1 / 4

• I will call the doc and ask for a stress echocardiography test instead - CORRECT ANSWER -I WILL CALL THE DOC AND
ASK FOR A STRESS ECHOCARDIOGRAPHY TEST
INSTEAD
Rationale; The exercise stress test requires the pt to walk on a treadmill or stationary bike for 30-60 minutes.The Stress Echocardiography test uses Dobutamine to stress the cardiac tissues without requiring the pt to walk or ride.The Weight lift test does not exist.
Approximately what % of coronary artery blockage is needed to cause angina?
• 45%
• 60%
• 75%
• 90% - CORRECT ANSWER -75%
Rationale; Anginal pain usually occurs when approximately 75% of the artery's diameter becomes occluded. Pain is usually more pronounced with exertion or emotional distress, when O2 demand by cardiac tissue cannot be met by O2 supply via the occluded arteries. The severity of the pain may be compounded with vasospams that further restrict blood flow through the coronary arteries. 3 / 4

A heart murmur associated with acute valvular regurg would be?
• S3
• S2
• S1
• S4 - CORRECT ANSWER -S4
