Question 1 of 5
The nurse is discussing the blood flow pattern of the heart. The nurse should recognize which of the following as the accurate blood flow pattern of the heart?
Correct Answer: C
Rationale: The correct blood flow pattern of the heart is C: vena cava→ right atrium-right ventricle-pulmonary artery-lungs-pulmonary vein-left atrium-left ventricle. This sequence accurately reflects the flow of deoxygenated blood from the vena cava into the right atrium, through the tricuspid valve into the right ventricle, then through the pulmonary artery to the lungs for oxygenation, returning as oxygenated blood via the pulmonary veins into the left atrium, passing through the mitral valve into the left ventricle, and finally being pumped out through the aorta to the rest of the body. The other choices either have the sequence of blood flow in the heart mixed up or have incorrect vessels in the sequence, leading to an inaccurate representation of the blood flow pattern in the heart.
