In managing post-mastectomy care, which of the following is advised to avoid edema?

In post-mastectomy care, avoiding edema is crucial for the patient's recovery and overall well-being. The correct choice emphasizes the importance of avoiding trauma and using protective measures. After a mastectomy, lymph nodes may be removed, which can disrupt normal lymphatic drainage and increase the risk of lymphedema, a condition characterized by swelling due to lymph fluid accumulation.

Implementing protective measures involves avoiding any actions that could potentially injure the arm on the surgical side, as injuries can exacerbate or trigger lymphedema. This includes avoiding tasks that put excessive strain on the affected arm, which could lead to irritation or swelling. Protective measures may also include wearing compression garments or practicing gentle movements to encourage lymphatic flow without overexertion.

The other actions listed are contraindicated in post-mastectomy care. Heavy lifting can create strain on the lymphatic system, taking blood pressure on the affected arm can cause unnecessary pressure and trauma, and vigorous stretching could lead to injury or exacerbate swelling. Thus, focusing on protection and careful management is essential in minimizing the risk of complications such as edema.
