A nurse is planning care for a client who has a spinal cord injury and spasm-induced incontinence. Which of the following medications should the nurse anticipate a prescription for?

Choice A Reason:

Hypoxemia due to dead space is not appropriate. Dead space refers to areas of the lung where ventilation occurs but no perfusion takes place. In ARDS, hypoxemia typically occurs due to ventilation-perfusion (V/Q) mismatch and shunting rather than dead space.

Choice B Reason:

Impaired carbon dioxide elimination due to shunting is not appropriate. Shunting occurs when blood bypasses ventilated alveoli, leading to inadequate gas exchange. In ARDS, shunting contributes to hypoxemia, but it doesn't directly impair carbon dioxide elimination.

Choice C Reason:

Decreased pulmonary arterial pressure due to ventilation-perfusion (V/Q) mismatch is incorrect. V/Q mismatch occurs when ventilation and perfusion are mismatched in different areas of the lung. This leads to areas of low ventilation (dead space) and areas of low perfusion (shunting). V/Q mismatch contributes to hypoxemia in ARDS but does not typically lead to decreased pulmonary arterial pressure.

Choice D Reason:

Decreased pulmonary compliance due to stiffness is correct. This is a characteristic feature of ARDS. The inflammation and damage to the alveoli cause them to become stiff, reducing pulmonary compliance and impairing lung expansion during ventilation.

Choice A Reason:

Bronchopneumonia is incorrect. Bronchopneumonia is characterized by patchy areas of consolidation involving multiple lobules scattered throughout the lungs. It typically results from bronchial obstruction and aspiration of infected material into the smaller airways and alveoli.

Choice B Reason:

Severe pneumonia is incorrect. "Severe pneumonia" is a broad term that can refer to pneumonia with various degrees of severity. It does not specifically describe the pattern of consolidation involving the entire lobe of the lung.

Choice C Reason:

Empyema is incorrect. Empyema refers to the accumulation of pus in the pleural cavity, often as a complication of pneumonia. It does not describe the pattern of consolidation within the lung tissue.

Choice D Reason:

Lobar pneumonia is correct. Lobar pneumonia is characterized by consolidation involving an entire lobe or lobes of the lung. It typically results from infection by a single pathogen, such as Streptococcus pneumoniae, which leads to inflammation and consolidation of an entire lobe of the lung.
