A patient has been diagnosed with acute respiratory distress syndrome (ARDS). For what other health condition should the healthcare professional assess this patient for as the priority?

Pneumonia

Heart failure

Pulmonary emboli

Acute pulmonary edema

Answer and Explanation

The Correct Answer is A

A. Pneumonia: Pneumonia is a common cause of acute respiratory distress syndrome (ARDS) and is associated with significant inflammation and alveolar damage. Assessing for pneumonia is a priority as it can exacerbate ARDS and lead to further respiratory compromise. Early identification and treatment of pneumonia can significantly improve the patient's outcome.

B. Heart failure: While heart failure can contribute to respiratory distress, ARDS is primarily a non-cardiogenic condition. Assessing for heart failure is important, but pneumonia is more directly linked to the development of ARDS and should be prioritized.

C. Pulmonary emboli: Although pulmonary embolism can cause acute respiratory distress, it is not the primary concern when dealing with ARDS. Assessing for embolism is important, but pneumonia is a more common and immediate concern in the context of ARDS.

D. Acute pulmonary edema: Acute pulmonary edema is usually associated with cardiac issues and is not the underlying cause of ARDS. While monitoring for pulmonary edema is necessary, pneumonia is the more relevant condition to assess in a patient diagnosed with ARDS.

Correct Answer is C

Explanation

A. It does not remain dormant but some host defenses can kill the bacteria: While the immune system can kill some of the Mycobacterium tuberculosis bacilli, in many cases, the bacteria evade complete eradication and persist in a dormant state within the lungs. This does not mean the infection is fully eliminated, as it can reactivate later.

B. Virulence factors in the bacilli weaken over time, leading to apoptosis: Mycobacterium tuberculosis does not naturally lose its virulence over time. Instead, it can persist in a latent state due to immune containment, not because of a reduction in its ability to cause disease.

C. The bacilli can become isolated within tubercles in the lungs, possibly encapsulated: In latent tuberculosis, the immune system walls off the bacilli within granulomas (tubercles), preventing active disease. These granulomas may be encapsulated with fibrous tissue, restricting bacterial growth and spread. The bacteria remain dormant but can reactivate if the immune system weakens.

D. Macrophages attack and phagocytize new areas of infection: While macrophages do play a role in the immune response to tuberculosis, they are often unable to completely eradicate the bacilli. Instead, the bacteria can survive within macrophages and trigger the formation of granulomas, which help contain but not eliminate the infection.

A. Veins that are most susceptible to a deep vein thrombosis are the peroneal, posterior tibial, popliteal and superficial femoral B. DVTS tend to mostly occur in the lower extremities but can occur in the upper extremities too C. A DVT is a type of venous thromboembolism (VTE), which is a blood clot that starts in the vein D. A deep vein thrombosis in the lower extremity has a low probability of becoming a pulmonary embolism

Correct Answer is D

Explanation

A. Veins that are most susceptible to a deep vein thrombosis are the peroneal, posterior tibial, popliteal and superficial femoral: This statement is correct. These veins are indeed among the most common sites for the development of DVT.

B. DVTs tend to mostly occur in the lower extremities but can occur in the upper extremities too: This statement is also correct. While DVTs primarily occur in the lower extremities, they can occur in the upper extremities as well, particularly in individuals with risk factors such as central venous catheters or certain medical conditions.

C. A DVT is a type of venous thromboembolism (VTE), which is a blood clot that starts in the vein: This statement is correct. DVTs are indeed classified as venous thromboembolism, which refers to blood clots that form in the venous system.

D. A deep vein thrombosis in the lower extremity has a low probability of becoming a pulmonary embolism: This statement is incorrect. A deep vein thrombosis in the lower extremity has a significant risk of becoming a pulmonary embolism if a thrombus dislodges and travels to the pulmonary circulation. It is essential to monitor and treat DVTs to reduce the risk of complications like pulmonary embolism.
