A nurse is teaching a client about adequate nutrition and hydration for the client with acquired immunodeficiency syndrome (AIDS). What is important to teach the client? (Select all that apply.)

Choice A reason: Blanching is not the term for black and necrotic tissue. Blanching is the temporary whitening of the skin when pressure is applied. It indicates that the blood flow is intact and the tissue is healthy.

Choice B reason: Cellulitis is not the term for black and necrotic tissue. Cellulitis is a bacterial infection of the skin and subcutaneous tissue. It causes redness, swelling, warmth, and pain in the affected area.

Choice C reason: Tunneling is not the term for black and necrotic tissue. Tunneling is a narrow channel or pathway that extends from the wound into the surrounding tissue. It indicates a deeper and more complex wound.

Choice D reason: Eschar is the term for black and necrotic tissue. Eschar is a thick, dry, and hard crust that forms over a wound. It indicates a severe tissue damage and impaired healing.

Choice A reason: This is the highest risk client because surgery can cause trauma, blood loss, and infection, which can weaken the immune system and increase the susceptibility to complications. The immune system is the body's defense mechanism that protects against foreign invaders, such as bacteria, viruses, or fungi. Surgery can damage the skin and tissues, which are the first line of defense, and cause inflammation, which can impair the function of the white blood cells, which are the second line of defense. The nurse should monitor the client's vital signs, wound healing, and signs of infection and administer antibiotics, fluids, and pain medication as ordered.

Choice B reason: This is not the highest risk client, but it is a moderate risk client because extreme anxiety can cause stress, which can affect the immune system and increase the vulnerability to illness. Stress is the body's response to a perceived threat or challenge, which can activate the sympathetic nervous system and the hypothalamicpituitaryadrenal (HPA) axis. Stress can cause the release of hormones, such as cortisol and adrenaline, which can suppress the immune system and reduce the production and activity of the white blood cells. The nurse should assess the client's anxiety level and provide coping strategies, such as relaxation, breathing, or counseling.

Choice C reason: This is not the highest risk client, but it is a low risk client because awaiting surgery can cause anxiety, which can affect the immune system and increase the vulnerability to illness. However, the client's anxiety level may not be as high as the client with extreme anxiety, and the client's immune system may not be as compromised as the client who has just had surgery. The nurse should assess the client's anxiety level and provide education, reassurance, and support.

Choice D reason: This is not the highest risk client, but it is a low risk client because delivering a baby can cause blood loss, hormonal changes, and fatigue, which can affect the immune system and increase the risk of infection. However, the client's immune system may not be as compromised as the client who has just had surgery, and the client may have some protection from the antibodies that are passed from the mother to the baby through the placenta and breast milk. The nurse should monitor the client's vital signs, lochia, and signs of infection and provide hygiene, nutrition, and rest.
