Histologic sections (routine H&E stain) of lung reveal the alveoli to be filled with pale, nongranular pink fluid. Neither leukocytes nor erythrocytes are present within this fluid. What is the most likely (i.e., most common) cause of this abnormality?
Correct Answer: B
Rationale: Congestive heart failure causes pulmonary edema, with transudative pink fluid in alveoli on histology, without inflammatory cells or blood.
Question 2 of 5
What is the most important nursing intervention for a client prescribed furosemide for pulmonary edema secondary to heart failure?

Rationale: Furosemide can cause hypokalemia, so potassium levels must be monitored.
Question 3 of 5
What assessment finding would indicate that spironolactone therapy is effective in a patient with heart failure?

Rationale: Spironolactone reduces fluid overload, leading to improved respiratory status and decreased peripheral edema.
Question 4 of 5
What is a priority nursing assessment when administering an ACE inhibitor to a patient with heart failure?
