What factor puts a client at greatest risk for developing lymphedema after a radical mastectomy?

The greatest risk factor for developing lymphedema after a radical mastectomy is related to any injury or trauma to the affected limb, such as an insect bite. After surgery, particularly one that involves the removal of lymph nodes like a radical mastectomy, the lymphatic system can be compromised. This makes the affected arm more susceptible to infections or complications like lymphedema, which is an accumulation of lymph fluid due to disrupted lymphatic drainage.

Insect bites can introduce bacteria and increase the risk of infection, which can trigger lymphedema in someone who has already had lymphatic damage from the surgical procedure. It is important for patients to take extra care to avoid any injuries or infections in the affected area to minimize their risk.

In contrast, significant weight loss or medication changes, such as the prescription of a calcium channel blocker, do not have a direct correlation with an increased risk of lymphedema. Similarly, engaging in a hobby like playing the piano doesn't inherently increase lymphedema risk unless it leads to strain or trauma to the affected arm. Therefore, any recent injury, particularly one that could lead to infection, is a key factor in determining the risk of lymphedema in
