Explanation:
The correct answer is E. The most likely diagnosis in this case is pulmonary embolus (PE). The risk factors for this patient are obesity and surgery. Pleuritic chest pain can develop in patients with a PE. Tachycardia, tachypnea, and increased oxygen requirements are highly suggestive of the diagnosis. The most appropriate test to confirm the clinical suspicion is a ventilation-perfusion scan.
A chest x-ray (choice A) can suggest a PE by showing a wedge-shaped area if there is an infarct; however, this is not the most sensitive or specific test to confirm the diagnosis. Chest x-ray films are most often normal.
A CT scan (choice B), like a chest x-ray, may reveal an area of infarct, but is not the most appropriate test in this scenario.
An ECG with rhythm strip (choice C) might show tachycardia, possible right axis deviation due to pulmonary hypertension, and right ventricular strain with ST-T wave changes. But, the most common finding is a normal ECG.
MRI (choice D) is used to show soft tissue abnormalities and is most often used in neurologic and orthopedic diagnoses. It would not be the test of choice for PE.
