While performing an assessment on a client with alterations in tissue integrity, which of the following cues should a nurse recognize as indicative of possible infection?

Choice A rationale Dry and itchy skin, or pruritus, is often associated with healing or chronic conditions like eczema and xerosis. While uncomfortable, it is not a primary indicator of an acute infectious process. Itching often results from the release of histamine during the inflammatory phase of wound healing or from a lack of sebaceous gland activity in damaged tissue. It does not typically signify the presence of pathogenic microorganisms requiring antibiotic therapy, though it can lead to secondary infections if the client scratches. Choice B rationale Increased pigmentation, or hyperpigmentation, usually occurs as a result of post inflammatory changes or chronic sun exposure. It is a sign of melanocyte activity in response to skin injury or inflammation but does not indicate an active infection. In some cases, it can be a normal part of the scarring process. Infection is more commonly associated with changes in color toward bright red or purple rather than a darkening of the skin's natural melanin or pigment. Choice C rationale Warmth and redness, also known as calor and rubor, are two of the classic cardinal signs of inflammation and infection. Increased blood flow to the site of injury occurs as the body delivers white blood cells to combat pathogens. If these signs spread beyond the immediate borders of a wound, it suggests cellulitis or a localized infectious process. This physiological response is triggered by chemical mediators like prostaglandins and kinins, which increase vascular permeability and vasodilation at the site. Choice D rationale The presence of hair follicles is a normal anatomical finding and generally indicates that the dermal layer is intact or regenerating effectively. Hair follicles are not associated with the pathology of infection. In fact, deep full thickness burns often destroy hair follicles, so their presence might actually suggest a more superficial injury. Their existence has no diagnostic value in determining whether a wound has been colonized or infected by bacteria, viruses, or fungi during the healing process.
