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

Answer and Explanation

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.

A. Previous stroke B. Irritants and and hypersensitivity to medications C. Previous intubation due to status asthmaticus episode D. Bronchial pneumonia

Correct Answer is C

Explanation

Choice A Reason:

Previous stroke is not directly associated with an increased risk of status asthmaticus. While individuals with certain medical conditions, such as neurological disorders, may have an increased risk of complications from severe asthma exacerbations, a previous stroke alone is not a recognized risk factor for status asthmaticus.

Choice B Reason:

Irritants and hypersensitivity to medications, may trigger asthma exacerbations, but they are not specific risk factors for status asthmaticus. Asthma exacerbations triggered by irritants or medications can typically be managed with appropriate treatment measures and do not necessarily lead to status asthmaticus.

Choice C Reason:

Previous intubation due to status asthmaticus episode is correct. Status asthmaticus is a severe and life-threatening asthma exacerbation that is unresponsive to standard treatment measures such as bronchodilators and corticosteroids. It is characterized by prolonged and severe bronchospasm, airway inflammation, and respiratory distress.

Choice D Reason:

Bronchial pneumonia is not a known risk factor for status asthmaticus. Bronchial pneumonia, or pneumonia affecting the bronchi and lungs, is a separate respiratory condition caused by bacterial, viral, or fungal infections. While pneumonia can exacerbate asthma symptoms in individuals with asthma, it is not specifically associated with an increased risk of status asthmaticus.
