AANP Family Nurse Practitioner (FNP) Certification ExamDiagnosisEasy
A 28-year-old female presents to the clinic with a chief complaint of a productive cough, fever, and chills for the past three days. She reports yellow-green sputum, shortness of breath, and pleuritic chest pain. On examination, crackles and egophony are noted in the right lower lobe. Her chest X-ray reveals right lower lobe consolidation. Which of the following is the most appropriate diagnosis?
- ACommunity-acquired pneumonia
- BViral pharyngitis
- CAcute bronchitis
- DAsthma exacerbation
Show answer & explanationAnswer & explanation
Correct answer: A. Community-acquired pneumonia
The patient's symptoms, physical exam findings, and chest X-ray results are classic for community-acquired pneumonia, making it the most appropriate diagnosis.
Why the other options are wrong
- B. Viral pharyngitis would present with a sore throat, without significant respiratory distress, crackles, or consolidation.
- C. Acute bronchitis typically presents with a cough but less severe systemic symptoms and no consolidation on chest X-ray.
- D. Asthma exacerbation primarily involves wheezing and bronchospasm, not typically consolidation or egophony.
Community-Acquired Pneumonia (CAP)
An acute infection of the lung parenchyma acquired outside of hospitals or extended-care facilities.
- Symptoms: cough (often productive), fever, chills, dyspnea, pleuritic chest pain.
- Physical exam: crackles, egophony, dullness to percussion.
- Diagnosis: often confirmed by chest X-ray showing infiltrates or consolidation.
Memory trick: Pneumonia's a 'CAP' on your lungs, making it hard to breathe.
