The nurse is performing the technique shown. What is the nurse assessing?

A. Tactile fremitus: This involves palpating vibrations on the chest wall as the patient speaks, not assessing chest expansion. B. Chest expansion: This technique assesses the symmetrical movement of the chest during inhalation and exhalation, which is the correct assessment for this context. C. Breath sounds: Breath sounds are assessed through auscultation rather than palpation. D. Tissue consolidation: This involves detecting areas of increased density in lung tissue, often assessed through percussion or auscultation, not through the technique shown for chest expansion.
