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 A
Explanation
Choice A Reason:
Falls is correct. Among individuals aged 65 years and older, falls are the most common cause of spinal cord injuries. As people age, they may experience changes in balance, mobility, and bone density, which can increase their risk of falling. Falls can occur both at home and in other environments, such as during outdoor activities or in healthcare settings. Spinal cord injuries resulting from falls in older adults can have significant consequences, including decreased mobility, chronic pain, and loss of independence.
Choice B Reason:
Gunshot wounds is incorrect. Gunshot wounds can cause spinal cord injuries, but they are not the most common cause for individuals aged 65 years and older. Gunshot wounds tend to be more common in younger age groups or in specific contexts such as violence-related incidents, which are less frequent in older adults.
Choice C Reason:
Sporting accidents is incorrect. Sporting accidents can also lead to spinal cord injuries, especially in younger and more active individuals participating in high-impact sports. However, among individuals aged 65 years and older, participation in sporting activities that could result in spinal cord injuries is generally less common compared to younger age groups.
Choice D Reason:
Motor vehicle accidents is incorrect.
Motor vehicle accidents can cause spinal cord injuries, but they are not as common in the elderly population as they are in younger age groups. Older adults may have reduced driving frequency or may be more cautious on the road, which decreases their risk of motor vehicle accidents compared to younger individuals.
Correct Answer is ["A","B","D"]
Explanation
Choice A Reason:
Muscle strength is correct. Assessing muscle strength is essential to determine if there are any neurological deficits or weakness that could indicate a neurological condition or injury. Sudden falls can be indicative of various neurological issues, such as stroke or transient ischemic attack (TIA). Assessing muscle strength helps identify any motor impairments or weakness that could contribute to the fall.
Choice B Reason:
Facial symmetry is correct. Assessing facial symmetry is crucial to identify any signs of facial droop, which could indicate a neurological deficit such as a stroke or Bell's palsy. Facial asymmetry may suggest damage to the facial nerve or other neurological issues.
Choice C Reason:
Peripheral pulses is incorrect. While assessing peripheral pulses is important for evaluating circulation, it may not be the priority assessment in this scenario where the client has suddenly fallen and may be experiencing neurological symptoms. Neurological deficits, such as weakness or changes in facial symmetry, vision, or speech, are more indicative of acute neurological issues like stroke or transient ischemic attack (TIA), which require immediate attention and intervention. In emergency situations, prioritizing assessments related to potential life-threatening conditions such as neurological deficits takes precedence over assessing peripheral pulses.
Choice D Reason:
Vision changes is correct. Assessing for vision changes is important to identify any visual disturbances or deficits that could contribute to falls or indicate underlying neurological issues such as a stroke or transient ischemic attack (TIA). Visual disturbances may include blurriness, double vision, or loss of vision in one or both eyes.
Choice E Reason:
Aphasia is incorrect. Assessing for aphasia, which is the inability to understand or express speech, is essential to identify any language deficits that could indicate a neurological condition such as a stroke. Aphasia may present as difficulty speaking, understanding language, or both.
