Which of the following is not a direct cause of ARDS?

Answer and Explanation

The Correct Answer is C

A. Near-drowning: This is a direct cause of ARDS. Inhalation of water can lead to pulmonary edema, which triggers ARDS.

B. Aspiration: Aspiration of gastric contents can directly injure the lungs and is a well-known cause of ARDS.

C. Pancreatitis: Pancreatitis is associated with ARDS, but it is an indirect cause, not a direct one. The inflammatory response from pancreatitis can lead to ARDS, but it is not due to direct lung injury.

D. Toxic inhalation: Inhaling toxic substances can cause direct damage to the alveoli and lead to ARDS.

Correct Answer is B

Explanation

A. "Now you can eat whatever you want": This is incorrect and dangerous advice. Lifestyle changes, including diet, are crucial for preventing the progression of coronary artery disease even after a CABG.

B. "A CABG is not a cure - It may improve your quality of life": This response educates the patient that while CABG can relieve symptoms and improve quality of life, it does not cure the underlying disease. Continued management and lifestyle changes are essential.

C. "I am happy for you": While this might express empathy, it does not provide the necessary education or correction of the patient’s misconception about CABG.

D. "A CABG is not a cure - but now you can stop taking your medications": This is incorrect. Most patients will need to continue taking medications such as antiplatelets, statins, and antihypertensives to manage their condition post-CABG.

A. Pallor and/or cyanosis of extremities B. Orthopnea, peripheral edema, crackles C. Dizziness, syncope. palpitations D. PAWP of 12 and CVP of 6

Correct Answer is B

Explanation

A. Pallor and/or cyanosis of extremities: While pallor and cyanosis can indicate severe heart failure, they are not early signs. These symptoms usually appear later in the disease process.

B. Orthopnea, peripheral edema, crackles: These are early signs of heart failure indicating fluid overload due to decreased cardiac output. Orthopnea is difficulty breathing when lying flat, peripheral edema is swelling in the limbs, and crackles indicate fluid in the lungs.

C. Dizziness, syncope, palpitations:These symptoms can occur in heart failure but are not specific to fluid overload; they are more indicative of decreased cardiac output and possible arrhythmias.

D. PAWP of 12 and CVP of 6: These values are within normal limits. PAWP (Pulmonary Artery Wedge Pressure) and CVP (Central Venous Pressure) would be elevated in fluid overload.
