During a skin inspection at the outpatient clinic, the nurse notices patches of thick, red skin with silvery scales on the client's elbows and knees. What skin abnormality does the nurse suspect?

Choice A reason: Inflammatory is the phase of wound healing that occurs at the time of injury and lasts about 35 days, because it is the first and immediate response to tissue damage. Inflammatory is the phase of wound healing that involves the activation of the immune system, the release of chemical mediators, the dilation of blood vessels, the increase of blood flow, the migration of white blood cells, and the formation of a clot. Inflammatory is the phase of wound healing that aims to control bleeding, prevent infection, and prepare the wound for healing.

Choice B reason: Proliferative is not the phase of wound healing that occurs at the time of injury and lasts about 35 days, but rather the phase of wound healing that occurs after the inflammatory phase and lasts about 23 weeks. Proliferative is the phase of wound healing that involves the growth and multiplication of new cells, the formation of granulation tissue, the synthesis of collagen, the contraction of the wound edges, and the development of epithelial tissue. Proliferative is the phase of wound healing that aims to fill the wound, restore the strength, and cover the defect.

Choice C reason: Maturation is not the phase of wound healing that occurs at the time of injury and lasts about 35 days, but rather the phase of wound healing that occurs after the proliferative phase and lasts about several months to years. Maturation is the phase of wound healing that involves the remodeling and reorganization of the collagen fibers, the reduction of scar tissue, the improvement of elasticity, and the restoration of function. Maturation is the phase of wound healing that aims to refine the wound, enhance the quality, and optimize the outcome.

Choice D reason: Intentional is not the phase of wound healing that occurs at the time of injury and lasts about 35 days, but rather a classification of wound healing that depends on the type and extent of tissue damage, the degree of contamination, and the method of closure. Intentional is a classification of wound healing that refers to wounds that are surgically created, have minimal tissue loss, are clean and sterile, and are closed by primary intention, which means that the wound edges are approximated with sutures, staples, or glue. Intentional is a classification of wound healing that results in faster healing, less scarring, and lower risk of infection.

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.
