Which of the following is NOT included in the treatment plan for angina pectoris?

The treatment plan for angina pectoris focuses on managing symptoms and reducing the risk of heart-related complications. Cardiac monitoring is essential because it allows healthcare providers to keep track of the heart's rhythm and any changes in condition that may occur during an angina episode. This monitoring helps in assessing the severity of angina and guiding treatment adjustments.

DVT prophylaxis may be considered for patients who are at risk of deep vein thrombosis, especially if they have limited mobility due to chest pain or underlying heart conditions. Prevention of DVT is important to ensure overall patient safety during treatment.

A chest x-ray is often conducted to rule out other conditions that might mimic angina symptoms or to assess the status of the heart and lungs. It can provide critical information about other potential issues such as heart enlargement or fluid in the lungs.

In contrast, subcutaneous insulin is not part of the treatment plan for angina pectoris. While insulin management is vital for patients with diabetes, it does not directly address the symptoms or underlying coronary artery disease that causes angina. Therefore, subcutaneous insulin does not fit within the framework of treating angina specifically, making it the correct answer to identify what is not included in the treatment plan.
