When caring for a chronic heart failure patient with left-sided failure, the nur

When caring for a chronic heart failure patient with left-sided failure, the nurse would most likely note the following statement in the physician’s written report following cardiac catheterization?
1. “Pressures in the left ventricle and atrium are increased.”
2. “Pressures in the left ventricle and atrium are decreased.”
3. “Pressures in the right ventricle and atrium match the ventricle pressures.”
4. “Pressures in the right ventricle reflect functioning of all heart chambers.”

1. “Pressures in the left ventricle and atrium are increased.”

None of the other choices reflect what exactly is going on with the heart with left sided failure. The atria is known as the "resting" phase because this is when the heart is getting filled with blood while the ventricles are responsible for contraction. With the left sided failure the heart continues to be filled up with blood and its size is increased because the left ventricle is unable to properly eject the blood out of the heart. The blood is backed up and the atrium also get too much blood filled into its chamber.

As the heart loses its ability to eject blood effectively from the left ventricle upon contraction, blood is retained in the left ventricle after systole and the chamber pressure rises due to the added blood volume. This patient is in left-sided heart failure, so pressure is higher in the left side of the heart, not the right side.
