Prepare for the NCLEX-RN® by exploring key insights into heart conditions: Tricuspid Atresia. Learn from expert nurse guidance on the affected heart location. Enhance your knowledge at Osmosis for comprehensive understanding.

The nurse is educating a client about tricuspid atresia. Which part of the heart should the nurse identify as the location affected by this condition?

The correct answer to today's NCLEX-RN® Question is...

The tricuspid valve is located between the right atrium and ventricle.

Major Takeaway

The tricuspid valve is located between the right atrium and the right ventricle and it allows blood from the atrium to flow down into the ventricle. Without it, blood cannot flow normally on this side of the heart. If there is no alternate route to direct the blood flow, there would be virtually no blood in the right ventricle available to be pumped to the lungs for oxygenation. This can also result in an underdeveloped or hypoplastic right ventricle. Tricuspid atresia, also known as pulmonary atresia, is a term used to describe an underdeveloped or absent tricuspid valve. Tricuspid atresia is a congenital condition for which the cause is not well understood, and is not as common as the other heart defects that obstruct or decrease pulmonary blood flow.
