Final answer:
Option B. The statement indicating a need for further teaching is that the client plans to wait a week after surgery to start hand strengthening exercises. Hand and arm exercises should typically begin sooner under the guidance of a healthcare provider to prevent complications and aid in recovery.
Step-by-step explanation:
A nurse is providing preoperative teaching for a client who is scheduled for a mastectomy. One of the client's statements that indicates a need for further teaching is "I'll wait until a week after surgery to start hand strengthening exercises." Typically, hand and arm exercises are recommended sooner than a week after surgery to help prevent complications such as lymphedema and to improve circulation and flexibility. It's important for the patient to follow a prescribed postoperative exercise regimen that normally starts within a day or two after surgery, under the guidance of their healthcare provider.
It is also true that the patient should avoid having procedures such as blood draws, IV insertions, or blood pressure measurements on the arm on the side where the mastectomy was performed. This is to reduce the risk of lymphedema in the affected arm. The statements about waiting 3-4 weeks before doing water aerobics and showering after the doctor removes the drain are generally correct and indicate understanding of standard postoperative care.
