A nurse is assessing a client who has chronic respiratory insufficiency. Which of the following findings should the nurse expect to find because of the long- term inadequate tissue perfusion?

A. Abdominal retraction is typically a sign of acute respiratory distress, not chronic respiratory insufficiency. B. Clubbing nails occurs as a chronic response to inadequate tissue oxygenation and is often associated with conditions like chronic obstructive pulmonary disease (COPD). C. Restlessness may occur during acute respiratory distress but is not a typical finding in chronic respiratory insufficiency. D. Dependent edema 4+ is more related to cardiac conditions such as heart failure rather than respiratory insufficiency, which generally results in more subtle signs like clubbing or cyanosis.
