A nurse is assessing a client who has acute respiratory distress syndrome (ARDS). Which of the following findings should the nurse expect?
Hypoxemia due to dead space
Impaired carbon dioxide elimination due to shunting
Decreased pulmonary arterial pressure due to ventilation-perfusion (V/Q) mismatch
Decreased pulmonary compliance due to stiffness
The Correct Answer is D
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.

Correct Answer is B
Explanation
Choice A Reason:
Nutritional therapy is not appropriate. While nutritional therapy may be involved in assessing the client's overall nutritional status and dietary needs, it may not specifically address the swallowing difficulty associated with Parkinson's disease.
Choice B Reason:
Speech therapy is appropriate. Speech therapy, also known as speech-language pathology, plays a crucial role in assessing and managing dysphagia. Speech therapists can evaluate the client's swallowing function and provide interventions to improve swallowing safety and efficiency.
Choice C Reason:
Occupational therapy is incorrect. Occupational therapy focuses on helping individuals engage in meaningful activities of daily living. While occupational therapists may play a role in dysphagia management, speech therapy is typically the primary discipline involved in addressing swallowing difficulties.
Choice D Reason:
Respiratory therapy: Respiratory therapy primarily focuses on evaluating and managing respiratory conditions, such as asthma, chronic obstructive pulmonary disease (COPD), and ventilator support. While dysphagia can sometimes lead to aspiration pneumonia and respiratory complications, respiratory therapists are not typically involved in the assessment and management of dysphagia itself.
Correct Answer is ["B","C","D","E"]
Explanation
Choice A Reason:
Obtaining a hospital bed and keeping all four siderails up, may not be the best choice. While a hospital bed with siderails may be appropriate for some individuals with Parkinson's disease who are at high risk of falls, keeping all four siderails up continuously can potentially restrict mobility and independence. It's important to balance safety with the client's comfort and ability to move independently.
Choice B Reason:
Removing all throw rugs from the home is correct. Throw rugs can be tripping hazards, especially for individuals with mobility issues or balance problems. Removing throw rugs can reduce the risk of trips and falls within the home.
Choice C Reason:
Installing handrails in the bathroom is correct. Installing handrails in the bathroom, especially near the toilet and shower, can provide additional support and stability for individuals with Parkinson's disease when performing daily activities. This can help prevent falls in a potentially slippery environment.
Choice D Reason:
Ensuring adequate lighting along walking spaces is correct. Good lighting is crucial for individuals with Parkinson's disease to see obstacles and hazards clearly. Adequate lighting along walking spaces helps improve visibility and reduces the risk of falls, especially during nighttime or low-light conditions.
Choice E Reason:
Keeping walking areas free of clutter is correct. Clutter and obstacles in walking areas increase the risk of tripping and falling, particularly for individuals with Parkinson's disease who may have difficulty with balance and coordination. Keeping walking areas clear of clutter helps create a safer environment.
