A client with suspected pulmonary edema is scheduled for an echocardiogram. What information can this diagnostic test provide to assist in diagnosing the cause of pulmonary edema?
Oxygen saturation levels
Blood pressure measurements
Assessment of cardiac structure and function
White blood cell count
The Correct Answer is C
A) Incorrect. Oxygen saturation levels are typically assessed using pulse oximetry and are not provided by an echocardiogram.
B) Incorrect. Blood pressure measurements are not directly assessed through an echocardiogram.
C) Correct. An echocardiogram provides valuable information about the structure and function of the heart, which can help diagnose the underlying cause of pulmonary edema, such as heart failure.
D) Incorrect. A white blood cell count is not part of an echocardiogram and is not used to diagnose pulmonary edema.

Correct Answer is B
Explanation
A) Incorrect. Urinary output is important but does not directly assess the client's oxygenation status.
B) Correct. Monitoring the respiratory rate and effort is essential to ensure the client is adequately oxygenated and not in respiratory distress.
C) Incorrect. Skin turgor is unrelated to oxygenation and pulmonary edema.
D) Incorrect. Bowel sounds do not provide information about the client's oxygenation status.
Correct Answer is A
Explanation
A) Correct. Increased hydrostatic pressure in pulmonary capillaries, often due to left ventricular failure, leads to the filtration of fluid from the capillaries into the alveoli and interstitial spaces, causing pulmonary edema.
B) Incorrect. Decreased capillary permeability is not typically a primary factor in the development of pulmonary edema.
C) Incorrect. Enhanced lymphatic drainage from the lungs is not a primary mechanism responsible for the accumulation of fluid in pulmonary edema.
D) Incorrect. Elevated colloid osmotic pressure in pulmonary vessels would oppose fluid accumulation in the alveoli and is not a primary cause of pulmonary edema.
