Final answer:
After a radical mastectomy, positioning the patient in semi-Fowler's with arm elevation aids venous return, reduces swelling, and minimizes postoperative complications.
Step-by-step explanation:
The patient recovering from a radical mastectomy will be placed in the semi-Fowler's position with the arm of the operative side elevated to promote venous return and lymphatic drainage, reduce swelling, and minimize the risk of complications such as lymphedema. Firstly, it helps to reduce swelling and promote drainage from the surgical site. Secondly, it improves respiratory function by allowing for better expansion of the lungs. Thirdly, it helps to prevent complications such as blood clots in the legs. This positioning helps to alleviate pain by reducing tension on the suture line and aids in proper respiratory function. Keeping the arm elevated is equally beneficial for encouraging proper circulation which can prevent blood clots and promote healing of the surgical site.
