A nurse is examining the nose of a client diagnosed with an upper respiratory tract infection. Which characteristics of the nasal mucosa should the nurse expect to find during assessment of a client with an upper respiratory tract infection?

Acute upper respiratory tract infection involves viral inflammation of nasal mucosa causing vasodilation edema hyperemia and increased secretions resulting from immune mediated epithelial response typically self limited course process present. Rationale: A. Bluish gray swollen nasal mucosa indicates cyanosis from hypoxia. reduced oxygenation causes tissue perfusion impairment in respiratory disease. inflammatory hyperemia absent unlike acute infection presentation findings. URTI typically produces red congested mucosa rather than gray appearance acute infection expected finding. B. Funnel chest is pectus excavatum congenital sternal depression deformity. it causes inward displacement of sternum reducing thoracic volume. respiratory compromise occurs in severe cases with cardiac compression. unlike emphysema it does not produce barrel chest expansion clinical presentation differs significantly. C. Pectus excavatum is congenital anterior chest wall deformity condition. it causes sternal depression decreasing thoracic capacity and efficiency. severe cases may impair cardiac output and exercise tolerance. it does not produce outward barrel chest configuration appearance seen clinically varying severity. D. Emphysema is chronic obstructive pulmonary disease characterized by alveolar destruction. loss of elastic recoil leads to air trapping and hyperinflation. patients develop dyspnea and increased anteroposterior chest diameter progressively worsening. producing barrel chest due to lung hyperinflation especially in smokers.
