The nurse reinforces teaching to the patient on left heart failure (HF). The nurse would evaluate the patient as understanding if the patient stated which of these occurs to blood flow through the heart?
Blood backs up from the left atrium.
Blood backs up from the left ventricle.
Blood backs up from the right ventricle.
Blood backs up from the right atrium.
The Correct Answer is B
Choice A Reason:In left HF, the left ventricle fails to pump blood forward efficiently, leading to congestion in the pulmonary circulation. As a result, blood backs up into the left atrium, causing symptoms such as pulmonary edema, shortness of breath, and fatigue. Left atrial enlargement may occur due to this backup of blood.
Choice B Reason:In left HF, blood does not back up from the left ventricle. Instead, the left ventricle itself is weakened and unable to propel blood effectively into the systemic circulation.
Choice C Reason:Blood backing up from the right ventricle is associated with right heart failure, not left HF. Right HF occurs when the right ventricle fails to pump blood efficiently, leading to congestion in the systemic venous circulation.
Choice D Reason:Blood backing up from the right atrium is also related to right heart failure. In left HF, the primary issue is congestion in the pulmonary circulation due to left ventricular dysfunction.

Correct Answer is ["A","C","D","E"]
Explanation
Choice A reason: An exercise stress test can help diagnose coronary artery disease by measuring the heart's ability to respond to external stress in a controlled clinical environment.
Choice B reason: Troponin I is a blood test that measures the levels of troponin T or troponin I proteins in the blood. These proteins are released when the heart muscle has been damaged, such as in a heart attack, which is a common complication of coronary artery disease.
Choice C reason: Cardiac computed tomography (CT) for calcium scoring is a non-invasive way of obtaining information about the presence, location, and extent of calcified plaque in the coronary arteries.
Choice D reason: Radioisotope imaging, such as a nuclear stress test, can show how blood moves to the heart muscle at rest and during stress, helping to diagnose coronary artery disease.
Choice E reason: Angiography involves using X-rays to see your body's blood vessels. Coronary angiography is specifically used to see if your coronary arteries are blocked or narrowed, where they supply blood to your heart.
