Cardiology unit exam OCEMT questions with correct
answers
1. Blood flow through the heart Correct Answer-RIGHT SIDE: Blood
enters the heart through two large veins, the inferior and superior vena
cava, emptying oxygen-poor blood from the body into the right atrium
of the heart. As the atrium contracts, blood flows from your right atrium
into your right ventricle through the open tricuspid valve. when the
ventricle is full, the tricuspid valve shuts (prevents blood from flowing
backward into the atria while the ventricle contracts). As the ventricle
contracts, blood leaves the heart through the heart through the pulmonic
valve, into the pulmonary artery and to the lungs where it is oxygenated
(CO2/O2 exchange). LEFT SIDE: the pulmonary vein empties oxygen
rich blood from the lungs into the left atrium of the heart. As the atrium
contracts, blood flows from your left atrium into your left ventricle
through the mitral valve. When the ventricle is full, the mitral valve
shuts (preventing backflow). As the ventricle conrtacts, oxygen enriched
blood leaves the heart through the aortic value into the aorta and to the
arteries, eventually to the veins to complete blood circulation.
2. best body position for performing high quality chest compressions
Correct Answer-supine position
3. How does aspirin work? Correct Answer-- reduces plaque buildup by
making platelets less sticky
- anti-inflammatory/ anti-fever agent, prevents platelets from clumping,
decreasing formation of new clots, relief of chest pain when considering
MI.
- shouldn't give to trauma patients or those taking anticoagulants
, 4. large vessels arteries and veins Correct Answer-a. aorta
b. veins take blood to the heart (superior vena cave , inferior vena cave)
c. arteries take blood away from heart
5. Understand all layers of the heart. Be able to identify Correct Answer-
a. Myocardium (heart muscle)
b. mitral/ bicuspid/ pulmonary valve prevent back flow from the left
ventricle to the atrium. Tricuspid valve prevents back flow between the
right ventricle and atrium
6. Primary action of Nitro Correct Answer-dilate arteries, vasodilation
7. Primary side effects of NTG and how the patient will present Correct
Answer-a. decreases perfusion
b. headache, dizziness, reduces blood pressure
8. Oxygenated blood coming from lungs enters where in the heart?
Correct Answer-- left atrium, mitral valve into the left ventricle
9. Understand the valves of the heart and where they are located Correct
Answer-a. coronary arteries supply the heart, fed during the diastolic
phase
b. tricuspid valve (right ventricle)
c. bicuspid valve (mitral valve)- left ventricle
