During palpation of the thorax, which parameter is associated with the skin?

• A. Temperature
• B. Tenderness
• C. Equal chest expansion
• D. Tactile fremitus

Answer: (A)

Temperature is the parameter associated with the skin because palpating the chest wall primarily assesses surface skin warmth, which reflects superficial blood flow and perfusion. This helps detect changes like fever or local inflammation affecting the skin over the thorax. The other options involve deeper or different aspects of the exam: tenderness is about pain on chest-wall palpation, equal chest expansion checks symmetry of lung movement, and tactile fremitus involves feeling the vibrations transmitted through the chest wall when speaking—relating to lung tissue and air conduction rather than the skin.
