A nurse is explaining the role of the lymphatic system in pulmonary edema to a client. What is the primary function of the lymphatic system in managing fluid balance in the lungs?
Facilitating gas exchange
Regulating blood pressure
Removing excess interstitial fluid
Producing surfactant
The Correct Answer is C
A) Incorrect. The primary role of the lymphatic system in the lungs is not gas exchange but rather fluid removal.
B) Incorrect. While the lymphatic system plays a role in overall fluid balance, it is not primarily responsible for regulating blood pressure.
C) Correct. The lymphatic system helps remove excess interstitial fluid from the lungs, preventing fluid accumulation and contributing to fluid balance.
D) Incorrect. Surfactant production is primarily related to maintaining lung compliance and preventing alveolar collapse but is not a primary function of the lymphatic system.

Correct Answer is A
Explanation
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 B
Explanation
A) Incorrect. Intravenous antibiotics may be necessary for certain pulmonary infections, but they do not address the immediate oxygenation needs in acute pulmonary edema.
B) Correct. Providing supplemental oxygen helps increase the client's oxygen levels, improving oxygenation in acute pulmonary edema.
C) Incorrect. While deep breathing exercises are beneficial for overall lung health, they may not be sufficient to address the immediate oxygenation issue in acute pulmonary edema.
D) Incorrect. Antipyretic medications are used to reduce fever and do not directly improve oxygenation in pulmonary edema.
