Which of the following is not a direct cause of ARDS?
Near-drowning
Aspiration
Pancreatitis
Toxic inhalation
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. An increase in O2 saturation to greater than 90%: An increase in oxygen saturation is typically a positive sign and does not indicate worsening heart failure.
B. The onset of atrial fibrillation: The development of atrial fibrillation in a patient with heart failure is a sign of worsening heart failure, as it indicates increased atrial pressure and the potential for further hemodynamic compromise.
C. Louder S1 and S2 heart sounds: Louder heart sounds do not specifically indicate worsening heart failure. They may vary based on other factors such as body habitus or the position of the patient.
D. A decrease in heart rate to 66 bpm: A heart rate of 66 bpm is within the normal range and does not suggest worsening heart failure.
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.
