A nurse is assisting with the plan of care for a client who has pneumonia and requires chest percussion, vibration, and postural drainage. Which of the following actions should the nurse plan to complete first?

Choice A rationale Positioning the client with the lung area to be drained superior to the trachea is the correct technique for postural drainage, utilizing gravity to move secretions toward the central airways. However, this action is part of the treatment application, which should follow the initial assessment to establish a baseline and identify the specific areas requiring intervention. Proper positioning is crucial for effective mucociliary clearance. Choice B rationale Auscultating lung fields first establishes a baseline assessment of the client's respiratory status, including the identification of abnormal breath sounds (e.g., crackles, rhonchi) and the specific lung segments with retained secretions requiring percussion and drainage. This assessment guides the choice of postural drainage positions and ensures the safety and effectiveness of the subsequent airway clearance therapies. The findings direct the rest of the procedure. Choice C rationale Providing mouth care is an important aspect of patient hygiene and comfort, typically performed after the airway clearance treatments (percussion, vibration, drainage) to remove any mobilized secretions that the client may have coughed up or swallowed. Performing it prior is unnecessary and less effective for removing post-treatment sputum and improving overall respiratory hygiene. Choice D rationale Cupping hands to perform chest percussion is the physical technique used to create a shock wave that loosens thick, tenacious pulmonary secretions from the bronchial walls. This is the treatment phase of the procedure, which should only be initiated after the respiratory assessment (auscultation) is complete and the client is correctly positioned for drainage.
