Question 1 of 5
A nurse is caring for a neonate born with a congenital heart abnormality. To better help the parents understand the impact of this disorder, the nurse begins by describing the unusual flow of blood through the heart which takes what course?
Correct Answer: D
Rationale: The correct answer is D. In a normal heart, oxygenated blood from the lungs enters the left atrium through the pulmonary veins. This oxygen-rich blood then flows into the left ventricle and is pumped out to the body. In a neonate with a congenital heart abnormality, this pathway may be disrupted, leading to potential complications.
Choice A is incorrect because deoxygenated blood from the body, not the lungs, enters the right atrium through the vena cava.
Choice B is incorrect as deoxygenated blood from the lungs enters the right atrium through the superior and inferior vena cava.
Choice C is incorrect as oxygenated blood from the lungs enters the left atrium, not the right atrium.
Understanding the normal flow of blood through the heart is crucial for comprehending the impact of congenital heart abnormalities on circulation and oxygenation in neonates.
