A nurse is providing teaching to a client who is postoperative following a mastectomy of the left breast with axillary lymph node dissection. Which of the following exercises should the nurse instruct the client to start on the first postoperative day?

Choice A rationale:
Is not suitable for a client who has undergone a mastectomy with axillary lymph node dissection. This exercise may put a strain on the surgical site and cause discomfort or injury.
Choice B rationale:
Is also not appropriate for a postoperative mastectomy client. It involves using the left hand extensively, which could potentially disrupt the healing process and cause pain.
Choice C rationale:
Is not recommended for a postoperative mastectomy client. It involves significant upper body movement, which may not be well-tolerated after surgery, especially with lymph node dissection.
Choice D rationale:
This exercise is suitable for a postoperative mastectomy client as it helps in maintaining hand and arm mobility without putting excessive strain on the surgical site. It also aids in preventing complications like lymphedema, which is a potential concern after lymph node dissection.

Choice A rationale:

Using fingers to remove loose tissue is not an appropriate action for the nurse to take when providing hydrotherapy for a burn wound. This action can cause further trauma to the wound and increase the risk of infection.

Choice B rationale:

Opening small blisters to expose air is contraindicated in burn wound management. The blister roof provides a natural barrier against infection, and puncturing them increases the risk of infection and delays the healing process.

Choice C rationale:

The correct answer is to wash the burn with a mild soap. Cleaning the burn wound with mild soap and water helps remove debris and minimize the risk of infection without causing additional damage.

Choice D rationale:

Applying wet-to-dry dressings is an outdated and inappropriate practice for burn wound care. Wet-to-dry dressings can be painful, disrupt wound healing, and increase the risk of infection. Modern burn wound care focuses on maintaining a moist environment to support optimal healing.
