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 ["A","D","E"]

Explanation

Choice A Reason:

The client admitted with diabetic ketoacidosis (DKA) is correct. Diabetes is a common cause of peripheral neuropathy, particularly if poorly controlled. Diabetic ketoacidosis (DKA) is a severe complication of diabetes characterized by high blood sugar levels and ketone accumulation. Prolonged uncontrolled diabetes can lead to nerve damage and peripheral neuropathy.

Choice B Reason:

The client admitted with sleep apnea is incorrect. Sleep apnea is a sleep disorder characterized by pauses in breathing or shallow breathing during sleep. While sleep apnea itself is not typically associated with peripheral neuropathy, underlying conditions such as obesity or diabetes, which are risk factors for sleep apnea, can also increase the risk of peripheral neuropathy.

Choice C Reason:

The client admitted with a hypertensive crisis is incorrect. Hypertension (high blood pressure) is not directly associated with peripheral neuropathy. However, poorly controlled hypertension can lead to vascular complications and contribute to conditions such as atherosclerosis, which may indirectly increase the risk of peripheral neuropathy.

Choice D Reason:

The client admitted for an exacerbation of Systemic Lupus Erythematosus (SLE) is correct. Systemic Lupus Erythematosus (SLE) is an autoimmune disease that can affect various organs and tissues, including the peripheral nerves. Peripheral neuropathy can occur as a complication of SLE, particularly in cases of active disease or as a result of certain medications used to treat SLE.

Choice E Reason:

The client admitted with untreated tuberculosis is incorrect. Tuberculosis (TB) is a bacterial infection caused by Mycobacterium tuberculosis. While TB itself is not typically associated with peripheral neuropathy, certain medications used to treat TB, such as isoniazid, can cause peripheral neuropathy as a side effect.

Choice F Reason:

The client admitted with cirrhosis secondary to chronic alcohol use is correct. Chronic alcohol use and cirrhosis can lead to various neurological complications, including peripheral neuropathy. Alcohol-related peripheral neuropathy often presents with sensory symptoms such as tingling, numbness, and pain in the extremities.

A. Epithelial cells B. OT lymphocytes C. Hyperreactivity D. Mast cells E. Inflammation

Correct Answer is ["A","D","E"]

Explanation

Choice A Reason:

Epithelial cells is correct. Epithelial cells lining the airways play a role in initiating the inflammatory response in asthma by releasing cytokines and other inflammatory mediators. These cells can contribute to the circulatory surge of inflammatory cells and cytokines seen in status asthmaticus.

Choice B Reason:

OT lymphocytes is incorrect. There is no specific cell type known as "OT lymphocytes." It's possible this may refer to T lymphocytes (T cells), which are involved in the immune response in asthma but are not typically associated with a circulatory surge in status asthmaticus.

Choice C Reason:

Hyperreactivity is incorrect. Hyperreactivity refers to the exaggerated response of the airways to various stimuli, leading to bronchoconstriction and inflammation. While hyperreactivity is a characteristic feature of asthma, it does not directly contribute to a circulatory surge of inflammatory cells and cytokines.

Choice D Reason:

Mast cells is correct. Mast cells are key players in the pathophysiology of asthma. They release various inflammatory mediators, including histamine and leukotrienes, which contribute to airway inflammation, bronchoconstriction, and mucus production. Mast cells can participate in the circulatory surge of inflammatory cells and cytokines in status asthmaticus.

Choice E Reason:

Inflammation is correct. Inflammation is a hallmark feature of asthma and plays a central role in the pathogenesis of status asthmaticus. The inflammatory response involves the recruitment and activation of various inflammatory cells, release of cytokines, and other mediators that contribute to airway obstruction and systemic effects.
