Final answer:
The nursing diagnosis underlying the discomfort associated with angina is Ineffective cardiopulmonary tissue perfusion secondary to CAD. Angina is chest pain or pressure that occurs when heart muscle cells do not receive adequate blood flow and become starved of oxygen.
Step-by-step explanation:
The nursing diagnosis underlying the discomfort associated with angina is Ineffective cardiopulmonary tissue perfusion secondary to CAD, as evidenced by chest pain. Angina is chest pain or pressure that occurs when heart muscle cells do not receive adequate blood flow and become starved of oxygen. This can be caused by a partial blockage of the coronary arteries due to the buildup of plaque, resulting in reduced blood flow and oxygen supply to the heart.
