A client with lupus may experience Raynaud's phenomenon. What should the nurse include when providing client education about this?

Choice A reason: Stage 1 is a wound that involves only the epidermis, the outermost layer of the skin. It appears as a nonblanchable redness, warmth, or hardness on intact skin. It does not have any breakage or ulceration of the skin.

Choice B reason: Stage 2 is a wound that involves the epidermis and the dermis, the second layer of the skin. It appears as a shallow, open, reddened ulcer with a partialthickness loss of skin. It may have some serous exudate, but no slough or eschar. It may also present as a blister or abrasion.

Choice C reason: Stage 3 is a wound that involves the epidermis, the dermis, and the subcutaneous tissue, the third layer of the skin. It appears as a deep, open, reddened ulcer with a fullthickness loss of skin. It may have some slough or eschar, but no exposed bone, tendon, or muscle. It may also have tunneling or undermining of the wound edges.

Choice D reason: Stage 4 is a wound that involves the epidermis, the dermis, the subcutaneous tissue, and the underlying structures, such as bone, tendon, or muscle. It appears as a deep, open, reddened ulcer with a fullthickness loss of skin and tissue. It has exposed bone, tendon, or muscle, which may be visible or palpable. It may also have slough, eschar, necrosis, infection, or osteomyelitis.

Choice A reason: Properly disposing of contaminated equipment is an important infectioncontrol measure, but it is not the most effective way to prevent the spread of pathogens during client care. Contaminated equipment, such as gloves, gowns, masks, or needles, should be disposed of in designated containers or bags to prevent exposure or injury to others. However, this measure does not eliminate the risk of transmission of pathogens from the hands of the health care worker to the client or the environment.

Choice B reason: Discarding used syringes into appropriate containers is an important infectioncontrol measure, but it is not the most effective way to prevent the spread of pathogens during client care. Used syringes, especially those that contain blood or body fluids, should be discarded into punctureresistant, leakproof, and labeled containers to prevent needlestick injuries or exposure to others. However, this measure does not eliminate the risk of transmission of pathogens from the hands of the health care worker to the client or the environment.

Choice C reason: Changing soiled linens is an important infectioncontrol measure, but it is not the most effective way to prevent the spread of pathogens during client care. Soiled linens, especially those that contain blood or body fluids, should be changed and handled with gloves and minimal agitation to prevent contamination or aerosolization of pathogens. However, this measure does not eliminate the risk of transmission of pathogens from the hands of the health care worker to the client or the environment.

Choice D reason: Performing hand hygiene is the most effective way to prevent the spread of pathogens during client care, because it reduces the number of microorganisms on the hands of the health care worker, which are the most common source and mode of transmission of infection. Hand hygiene should be performed before and after contact with the client, after contact with potentially infectious materials, after removing gloves, and before and after performing invasive procedures. Hand hygiene can be performed by washing with soap and water or using alcoholbased hand rubs.
