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","C","D","E","F"]
Explanation
Choice A Reason:
Easily getting back to sleep after awakening is incorrect. This is not typically a manifestation of obstructive sleep apnea. Instead, individuals with OSA often experience fragmented sleep due to frequent awakenings caused by apnea episodes.
Choice B Reason:
Many episodes of apnea per night is correct. Yes, individuals with obstructive sleep apnea experience many episodes of apnea (complete cessation of breathing) or hypopnea (partial obstruction of airflow) per night. These episodes can occur multiple times throughout the night, disrupting normal sleep patterns.
Choice C Reason:
Loud snort after breathing cessation is correct. This is a characteristic manifestation of obstructive sleep apnea. Individuals with OSA often make choking, snorting, or gasping sounds after a period of breathing cessation as they attempt to resume breathing.
Choice D Reason:
10 seconds or longer of breathing cessation is correct. Yes, breathing cessation episodes in obstructive sleep apnea typically last for 10 seconds or longer. These prolonged episodes of apnea contribute to oxygen desaturation and disrupted sleep.
Choice E Reason:
Daytime sleepiness is correct. Yes, daytime sleepiness is a common symptom of obstructive sleep apnea. Disrupted sleep patterns and frequent awakenings during the night can lead to excessive daytime sleepiness, fatigue, and decreased alertness.
Choice F Reason:
Frequent, loud snoring is correct. Yes, frequent, loud snoring is a hallmark symptom of obstructive sleep apnea. Snoring occurs due to the partial obstruction of airflow in the upper airway during sleep.
Correct Answer is ["A","C","D"]
Explanation
Choice A Reason:
Take small bites of food is correct. Taking small bites of food can help prevent choking and aspiration, particularly during mealtime. It is a recommended practice for individuals with epilepsy to reduce the risk of aspiration if a seizure were to occur during eating.
Choice B Reason:
Liquids should be thickened is incorrect. Thickened liquids are typically recommended for individuals with swallowing difficulties (dysphagia) to help prevent aspiration. However, thickened liquids may not be necessary for all individuals with epilepsy unless specifically indicated based on their swallowing function assessment.
Choice C Reason:
Eat sitting slightly forward correct.: Eating while sitting slightly forward can help prevent aspiration in case of a seizure during meals. This position allows gravity to assist in preventing food or liquid from entering the airway.
Choice D Reason:
Chew food thoroughly before swallowing is correct. Thoroughly chewing food before swallowing is important for proper digestion and to reduce the risk of choking or aspiration, especially for individuals with epilepsy who may be at increased risk of aspiration during a seizure.
Choice E Reason:
Avoid having conversations while eating is incorrect. Avoiding conversations while eating is not directly related to epilepsy management. However, focusing on eating and taking appropriate precautions, such as sitting upright and chewing food thoroughly, can help reduce the risk of aspiration during meals.
Choice F Reason:
Avoid fiber in the diet is incorrect.: There is no specific recommendation to avoid fiber in the diet for individuals with epilepsy. In fact, a balanced diet that includes fiber-rich foods can promote overall health and well-being, which is important for individuals with epilepsy as well.
