A client with newly diagnosed Crohn’s disease asks the nurse about dietary restrictions. How should the nurse respond?

Managing dyspnea in emphysema requires applying knowledge of respiratory mechanics and airway collapse. The nurse must instruct the client on techniques that maintain positive airway pressure during exhalation to prevent premature bronchial collapse, thereby facilitating better alveolar emptying and reducing air trapping for improved gas exchange.

Choice A rationale: While diaphragmatic breathing is beneficial, lying down on the side with knees bent is not the priority for acute dyspnea. This position does not specifically address the air trapping and airway collapse that occur in emphysema during the expiratory phase of respiration.

Choice B rationale: Increasing the breathing rate is counterproductive for a client with emphysema. Tachypnea leads to shallow breathing and increased air trapping, which worsens hypercapnia and respiratory fatigue. Slower, controlled exhalation is required to effectively manage the physiological dead space and improve ventilation.

Choice C rationale: Pursed-lip breathing creates back pressure in the airways, keeping them open longer during exhalation. This allows for more complete emptying of the alveoli, reduces the work of breathing, and helps alleviate the shortness of breath caused by trapped air.

Choice D rationale: Raising hands above the head may temporarily expand the chest wall, but it does not improve the function of the diaphragm. In emphysema, the diaphragm is often flattened; the most effective way to improve gas exchange is through techniques that optimize the expiratory phase.

Choice A reason: Explaining the five positions for postural drainage is correct, as COPD clients benefit from varied postures to drain mucus from different lung segments. Positioning enhances gravity-assisted clearance, improving airway patency and gas exchange, ensuring the client understands the procedure for effective participation.

Choice B reason: Performing drainage after meals is incorrect, as it risks aspiration and discomfort due to gastric pressure in COPD clients with hyperinflated lungs. Timing drainage between meals ensures safety and efficacy, making this approach inappropriate for mucus clearance.

Choice C reason: Obtaining an ABG before drainage is unnecessary unless respiratory distress is evident. Postural drainage is routine in COPD to clear mucus, and ABGs monitor acid-base status, not procedure efficacy, making this choice irrelevant for standard drainage preparation.

Choice D reason: Instructing shallow, fast breathing is incorrect, as it reduces tidal volume, worsening mucus clearance in COPD. Deep, slow breathing enhances drainage by mobilizing secretions, making this approach counterproductive to the goal of improving airway clearance during the procedure.
