The nurse continues the respiratory assessment of a client's chest excursion by placing both hands as seen in the picture. Which instruction should the nurse give the client?

A. Take a deep breath. The nurse is assessing chest excursion, a technique used to evaluate the symmetry and extent of thoracic expansion during respiration. This is done by placing both hands on the patient's posterior thorax with thumbs close to the midline and asking the patient to take a deep breath. As the patient inhales deeply, the nurse observes the movement of the thumbs apart, which should be symmetrical. B. Lean forward. Leaning forward is often advised for patients with dyspnea (e.g., in COPD) to improve breathing efficiency by reducing the work of accessory muscles. However, it is not relevant for assessing chest excursion. C. Cough vigorously. Coughing is useful in assessing airway clearance and the effectiveness of cough reflexes, commonly evaluated in patients with respiratory infections or conditions like bronchitis or pneumonia. However, it does not assess chest expansion. D. Hold your breath. Holding the breath may be useful in specific pulmonary function tests such as assessing breath-holding time in pulmonary function tests, but it does not provide information about chest excursion.
