Final answer:
Nurses will instruct patients with stable angina pectoris to adopt lifestyle changes, monitor symptoms, and manage other health conditions in addition to using nitroglycerin as needed for chest pain.
Step-by-step explanation:
A patient with stable angina pectoris taking nitroglycerin on an as-needed basis should be instructed by the nurse to adopt several additional management strategies beyond pharmacotherapy. This includes lifestyle modifications such as avoiding activities that trigger angina attacks, following a heart-healthy diet, maintaining a healthy weight, quitting smoking, and engaging in regular, moderate physical activity. Patients should be educated on stress reduction techniques and the importance of closely monitoring their symptoms, recognizing when they are worsening, and understanding when to seek immediate medical attention. Additionally, they should adhere to any prescribed medications that help to manage blood pressure, cholesterol levels, or other underlying conditions contributing to the angina.
