A nurse is caring for a client who has a pulmonary embolism. The nurse should identify that the release of inflammatory mediators leads to which of the following pathologic findings?

Choice A Reason:

"Do panting breaths several times a day." This statement is inappropriate. Panting breaths involve rapid, shallow breathing similar to what a dog does when it's hot. This technique may not be as effective in clearing mucus or promoting lung expansion compared to deep coughing. While panting breaths may have some benefits in promoting ventilation and increasing lung volume, they may not be as targeted or efficient in preventing atelectasis as other techniques such as deep coughing

Choice B Reason:

"Perform deep coughing twice a day." This statement is correct. Deep coughing helps clear mucus and secretions from the airways, reducing the risk of blockages that can lead to atelectasis. It promotes airway clearance and lung expansion, maintaining respiratory function. Regular deep coughing is particularly important for individuals with spinal cord injuries, as they may have impaired cough reflexes or weakened respiratory muscles, increasing their vulnerability to atelectasis.

Choice C Reason:

"Strengthen your chest muscles by performing therapy exercises." This statement is incorrect. While strengthening chest muscles through therapy exercises can be beneficial for overall respiratory health, it may not directly target the prevention of atelectasis. Atelectasis is primarily caused by the collapse of lung tissue due to mucus buildup or reduced lung expansion, rather than weakness of chest muscles. While therapy exercises may have other benefits such as improving respiratory function and endurance, they may not be the most effective strategy for preventing atelectasis in individuals with spinal cord injuries.

Choice D Reason:

"Get plenty of rest throughout the day." This statement is incorrect. Rest is important for overall health and well-being, but it may not directly contribute to the prevention of atelectasis. Inactivity and prolonged bed rest can actually increase the risk of atelectasis by reducing lung expansion and promoting mucus accumulation in the airways. While adequate rest is necessary for recovery and energy conservation, it should be balanced with activities that promote lung expansion and airway clearance, such as deep breathing exercises and mobility.

Choice A Reason:

Flail chest is incorrect. Flail chest is a condition characterized by multiple rib fractures, causing instability in the chest wall. While it can lead to respiratory distress, it doesn't directly cause ventilation-perfusion (V/Q) mismatch. Instead, it impairs the mechanics of breathing by compromising chest wall integrity.

Choice B Reason:

Emphysema is a chronic obstructive pulmonary disease (COPD) where the alveolar walls are destroyed, leading to a loss of surface area for gas exchange. This results in areas of the lungs that are well-perfused but poorly ventilated, causing a V/Q mismatch. The damage to alveoli leads to impaired ventilation, while blood flow may still be adequate, leading to hypoxemia (low oxygen levels in the blood).

Choice C Reason:

CHF primarily affects the heart’s ability to pump blood effectively, leading to pulmonary congestion and impaired gas exchange. However, it typically causes diffusion defects rather than a direct ventilation-perfusion mismatch. V/Q mismatch may occur secondary to pulmonary edema, but it’s not the primary mechanism of respiratory failure in CHF.

Choice D Reason:

Guillain-Barré syndrome is incorrect. Guillain-Barré syndrome (GBS) is a neurological disorder that affects the peripheral nervous system, leading to muscle weakness and paralysis. While respiratory muscle weakness can occur in GBS, it doesn't directly cause ventilation-perfusion (V/Q) mismatch. GBS primarily affects nerve function rather than lung function.
