Common manifestations of pneumonia in older patients?

• A. Confusion, stupor, and hypothermia
• B. Productive cough, fever, pleuritic chest pain
• C. Severe dyspnea with tachycardia
• D. Jaundice

Answer: (A)

In older adults, pneumonia often presents atypically, with changes in mental status being a common first clue. Delirium or confusion, sometimes with a reduced level of alertness or even stupor, can appear without the classic fever. The fever response is frequently blunted in the elderly, so hypothermia may occur instead of a fever. This pattern—confusion or delirium with possible hypothermia—best reflects how pneumonia commonly shows up in this age group.

The other patterns are less typical for older patients. A productive cough with fever and pleuritic chest pain is more characteristic of younger adults who mount a more classic inflammatory response. Severe dyspnea with tachycardia can occur but isn’t the most common presenting sign in the elderly, and jaundice is not a typical pneumonic manifestation and points more toward liver or biliary issues.
