A nurse in the emergency department is assessing an older adult client who has community-acquired pneumonia. Which of the following findings should the nurse expect?

Rationale: A. Confusion is a common manifestation of pneumonia in older adults due to hypoxia and systemic infection, even if typical respiratory symptoms are mild or absent. B. Hypertension is not a typical finding; pneumonia may actually cause hypotension in severe cases due to sepsis. C. Unequal pupils are unrelated to pneumonia and may indicate neurological issues. D. Tympany upon chest percussion indicates air in the pleural space (e.g., pneumothorax), not consolidation from pneumonia.
