A nurse is listening to the lungs of a hospitalized post-surgical patient and notes diminished breath sounds in the right lower lobe. The patient has an elevated temperature and green sputum. These findings could indicate _____ because of _____.
nosocomial pneumonia; lung tissue atelectasis
lung tissue atelectasis; community-acquired pneumonia
pulmonary edema; right heart failure
pulmonary edema; left heart failure
The Correct Answer is A
A. Nosocomial (hospital-acquired) pneumonia is common in post-surgical patients, particularly those with atelectasis, as diminished ventilation can lead to infection. The green sputum and fever are signs of infection.
B. Lung tissue atelectasis may predispose a patient to pneumonia, but community-acquired pneumonia is less likely in a hospitalized patient, and the green sputum is more indicative of nosocomial infection.
C. Pulmonary edema is associated with fluid in the lungs but does not typically cause green sputum or elevated temperature, which suggest infection.
D. Left heart failure may lead to pulmonary edema but is not associated with green sputum or fever.
