A nurse is caring for a client undergoing diagnostic evaluation for suspected pulmonary edema. Which finding on an arterial blood gas (ABG) analysis is consistent with pulmonary edema?

Decreased pH (acidosis)

Elevated partial pressure of oxygen (PaO2)

Decreased partial pressure of carbon dioxide (PaCO2)

Increased bicarbonate (HCO3-) levels

Answer and Explanation

The Correct Answer is A

A) Correct. Pulmonary edema can lead to impaired gas exchange, resulting in respiratory acidosis, characterized by a decreased pH on ABG analysis.

B) Incorrect. Pulmonary edema typically leads to decreased oxygenation, so an elevated PaO2 would not be consistent with this condition.

C) Incorrect. A decreased PaCO2 is more commonly associated with respiratory alkalosis and is not a primary finding in pulmonary edema.

D) Incorrect. Increased bicarbonate (HCO3-) levels are more indicative of metabolic alkalosis and are not typically associated with pulmonary edema.

Correct Answer is C

Explanation

A) Incorrect. While a complete blood count (CBC) may provide some information, it is not the primary diagnostic test for pulmonary edema.

B) Incorrect. An electrocardiogram (ECG) may be used to evaluate cardiac function but does not directly assess pulmonary edema.

C) Correct. A chest X-ray is a key diagnostic tool for assessing the presence, severity, and underlying causes of pulmonary edema by visualizing lung and heart structures.

D) Incorrect. Urinalysis is not a primary diagnostic test for pulmonary edema; it is used to assess kidney function and screen for urinary tract infections.

A. Urinary output B. Respiratory rate and effort C. Skin turgor D. Bowel sounds

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.
