Which arm should not be used for blood pressure if the patient has mastectomy on that side?

Explanation:
Avoid using the arm on the side of the mastectomy for blood pressure measurement. After mastectomy with possible axillary lymph node removal, the lymphatic drainage on that side can be impaired, and inflating a cuff there can increase swelling or trigger lymphedema. The opposite arm remains the appropriate site for BP unless there is another contraindication (for example, an IV line or other limb injury). In such cases, follow facility policy and use the available alternative site.
