A nurse is assessing a 12-year-old client. Which of the following assessment findings indicates the need for further evaluation regarding cellulitis?

Cellulitis is a deep bacterial infection of the dermis and subcutaneous tissues. Assessment requires identifying signs of skin barrier compromise and localized inflammation, such as erythema, warmth, and edema, to prevent systemic progression like bacteremia or necrotizing fasciitis. Choice A rationale Pustules around the mouth often suggest impetigo, a superficial infection typically caused by Staphylococcus aureus or Streptococcus pyogenes. Cellulitis involves deeper tissue layers and presents with diffuse spreading redness rather than localized perioral pustular clusters. Choice B rationale Scaly facial patches are indicative of fungal infections like tinea faciei or inflammatory conditions like seborrheic dermatitis. These lack the acute inflammatory markers of cellulitis, which typically presents with intense warmth, tenderness, and non-circumscribed edema. Choice C rationale Hyperpigmentation usually results from chronic venous insufficiency, post-inflammatory changes, or endocrine disorders. Cellulitis is an acute infectious process characterized by rapid-onset erythema and swelling rather than stable changes in skin melanin distribution or pigment deposition. Choice D rationale Open, weeping lesions provide a portal of entry for bacteria like Group A Streptococcus into the subcutaneous space. This finding necessitates evaluation for secondary cellulitis, as compromised skin integrity is the primary risk factor for infection.
