Pink, frothy sputum

Low-grade fever

Clear breath sounds throughout the lung fields

A) Correct. Pink, frothy sputum, often described as "pink froth," is indicative of severe pulmonary edema with the presence of blood-tinged fluid in the alveoli.

B) Incorrect. A low-grade fever is not a typical sign of pulmonary edema and may indicate another underlying condition.

C) Incorrect. Clear breath sounds throughout the lung fields are not indicative of severe pulmonary edema, which often presents with crackles.

Correct Answer is C

Explanation

A) Incorrect. Hyperventilation leading to respiratory alkalosis may occur in response to respiratory distress but is not the primary cause of the sensation of "suffocation."

B) Incorrect. Reduced cardiac output may be a consequence of pulmonary edema, but it does not typically result in bradycardia, nor is it the primary cause of the sensation described.

C) Correct. In pulmonary edema, fluid accumulation in the alveoli impairs oxygen diffusion, leading to hypoxemia, which contributes to the sensation of "suffocation."

D) Incorrect. Elevated blood pressure and hypertension can be associated with heart failure but are not the primary factors contributing to the sensation of "suffocation" in pulmonary edema.

A. Nausea and vomiting B. Orthopnea (difficulty breathing when lying flat) C. Excessive sweating and diaphoresis D. Sharp, stabbing chest pain

Correct Answer is B

Explanation

A) Incorrect. Nausea and vomiting are not typically associated with pulmonary edema.

B) Correct. Orthopnea, or difficulty breathing when lying flat, is a common symptom of pulmonary edema related to heart failure.

C) Incorrect. While sweating and diaphoresis can occur in response to respiratory distress, they are not specific to pulmonary edema.

D) Incorrect. Sharp, stabbing chest pain is not a common manifestation of pulmonary edema but may occur with other cardiac or respiratory conditions.
