30 Useful Free CNA Practice Test Questions and Answers on Chest Pain

How does the newly replenished blood get from the lungs to the heart?

• The coronary arteries
• 4 pulmonary veins
• Capillary beds
• Pulmonary arteries

Which of the coronary arteries supply the intra-ventricular septum with clean blood?

• Left main coronary artery
• The coronary arteries
• Pulmonary arteries
• Right coronary artery

What is angina pectoris?

• Angina pain lasts <15 mins; AMI > 15 minutes
• Left coronary artery carries 85% of the needed blood.
• Cardiac output is the amount of blood pumped by the ventricles per minute, which can increase by increasing heart rate, stroke volume, or both combined
• Angina pectoris is a sign of myocardial ischemia; the term literally means "choking pain in the chest" and is caused by an imbalance between myocardial oxygen supply and demand.

Which coronary artery supplies the most arterial blood that the myocardium requires?

• Left coronary artery carries 85% of the needed blood.
• Right coronary artery
• The coronary arteries
• Left main coronary artery

What 3 conditions affect stroke volume?

• The coronary arteries
• Preload, afterload, and cardiac contractility.
• Left atrium and ventricle.
• Left main coronary artery

What is preload?

• The erosion or rupturing of artheromatous plaque.
• The volume of blood returning to the heart after the cardiac cycle.
• Left atrium and ventricle.
• Left coronary artery carries 85% of the needed blood.

How does the heart receive the blood it needs to nourish the myocardium?

• Pulmonary arteries
• Right coronary artery
• The coronary arteries
• Left main coronary artery

Once the left atrium is full of fresh blood, what happens next?

• The volume of blood returning to the heart after the cardiac cycle.
• The stroke volume is the amount of blood ejected from the ventricles during each contraction.
• Left atrium and ventricle.
• It opens the mitral valve between the left atrium and ventricle, allowing the left pump (ventricle) to fill with blood, before it is pumped through out the body, to once again nourish the cells.

What are the "primer pumps" of the heart?

• Atria/atrium
• Capillary beds
• Pulmonary arteries
• 4 pulmonary veins

Where does the exchange of oxygen and carbon dioxide take place in the coronary circulation?

• Atria/atrium
• 4 pulmonary veins
• Capillary beds
• Pulmonary arteries

What are the 2 main conditions that is seen in patients with ACS?

• The erosion or rupturing of artheromatous plaque.
• 3; The cordonae tendonae are those small thread like tendons that are attach the mitral valve.
• An acute myocardial infarction (AMI) and unstable angina (UA) are part of a spectrum of disease, collectively known as acute coronary syndromes (ACS). It is the most common cause of sudden cardiac death in the US.
• The volume of blood returning to the heart after the cardiac cycle.

How many connections within the heart does the tricuspid have and what are the connections called?

• The volume of blood returning to the heart after the cardiac cycle.
• 3; The cordonae tendonae are those small thread like tendons that are attach the mitral valve.
• Left coronary artery carries 85% of the needed blood.
• The erosion or rupturing of artheromatous plaque.

Which section of the ANS is responsible for a decrease in cardiac output?

• Peripheral vascular resistance / afterload
• The coronary arteries
• Within 6 hours of onset.
• Parasympathetic nervous system branch of the ANS.

What is afterload?

• The erosion or rupturing of artheromatous plaque.
• The volume of blood returning to the heart after the cardiac cycle.
• They often result from atherosclerosis of the coronary or peripheral arteries.
• The resistance to blood flow that the heart must pump against in order to sustain a BP.

What is the stroke volume of the heart?

• The volume of blood returning to the heart after the cardiac cycle.
• Cardiac output is the amount of blood pumped by the ventricles per minute, which can increase by increasing heart rate, stroke volume, or both combined
• The stroke volume is the amount of blood ejected from the ventricles during each contraction.
• They often result from atherosclerosis of the coronary or peripheral arteries.
