The nurse realizes that client teaching regarding the cause of anginal pain was effective when the client makes which statement?
1. "The pain is related to remodeling of the heart muscle caused by narrowed arteries."
2. "The heart is not pumping enough blood out with each beat because of narrowed arteries."
3. "The pain is from a lack of oxygen getting to the heart, which is caused by narrowed arteries."
4. "The pain comes from the heart beating irregularly because of narrowed arteries."
Correct Answer: 3
Rationale 1: Remodeling of the heart muscle can make the heart more susceptible to angina, but it is not the actual source of angina.
Rationale 2: Low cardiac output is not the actual source of angina but can be a contributing factor.
Rationale 3: Angina pectoris is acute chest pain caused by the coronary arteries' inability to maintain adequate oxygenation to meet the metabolic demands of the myocardium. This is usually caused by a narrowing of the coronary vessels.
Rationale 4: An irregular heartbeat is not the actual source of angina but can be a contributing factor.
