A nurse is reinforcing teaching with a client who has acute glomerulonephritis with edema. Which of the following statements should the nurse make?

Choice A Reason:
Allowing the affected area to remain open to air is not the best practice for managing burns. While it's important not to cover the burn with tight or adhesive dressings, the area should be covered with a clean, dry cloth to protect it from further injury and contamination.

Choice B Reason:
Running cool water over the affected area is recommended for minor burns. This helps to cool the burn, reduce pain, and prevent further tissue damage. The water should be cool, not cold, as extremely cold temperatures can cause further damage to the affected tissue.

Choice C Reason:
Maintaining skin integrity over the blisters is important, but this choice is incomplete. Blisters should not be intentionally ruptured, as they provide a natural barrier to infection. If a blister does break, the area should be cleaned gently, and an antibiotic ointment may be applied before covering with a sterile dressing.

Choice D Reason:
Applying ice directly to the burn is not recommended. Ice can cause further damage to the burned skin and may lead to frostbite. Instead, only cool water should be used as mentioned in choice B.

Choice E Reason:
Administering ibuprofen for pain is appropriate for a minor burn. Ibuprofen can help reduce inflammation and alleviate pain. However, it's important to ensure that the client has no contraindications to ibuprofen, such as allergies or stomach ulcers.

Choice A reason:
Using the client's left arm to obtain blood samples is the correct action to prevent lymphedema after a right radical mastectomy. Lymphedema can occur when the lymphatic drainage is disrupted, which is a risk after mastectomy involving lymph node removal. To reduce this risk, it is recommended to avoid procedures such as blood draws and blood pressure measurements on the affected side.

Choice B reason:
Obtaining blood pressure readings using the client's right arm, the side of the mastectomy, is not recommended. This action can increase the risk of lymphedema due to the pressure applied during the measurement, which can impede lymphatic flow and contribute to fluid accumulation.

Choice C reason:
Keeping both arms below the level of the client's heart is not specifically related to the prevention of lymphedema. While elevation of the affected arm can help promote lymphatic drainage and reduce swelling, there is no recommendation to keep both arms below heart level as a standard practice.

Choice D reason:
Limiting range-of-motion exercises with the affected arm is not advised as a means to prevent lymphedema. In fact, gentle range-of-motion exercises are encouraged postoperatively to prevent stiffness and improve mobility. However, these exercises should be performed carefully and gradually to avoid overexertion, which could lead to lymphedema.
