your best friends dad went to the doctor recently because he had a cough for about two weeks. the doctor suspects a diagnosis of pneumonia. what radiographic test might the doctor order to obtain images of the anterior, posterior, and lateral views of the lungs?

• ventilation/perfusion (v/q) scan
• chest x-ray (cxr)
• thoracentesis
• pulmonary angiography

question 31

your grandma has been complaining that your grandpa snores so loudly it keeps her up at night. your grandpa agrees to see the doctor because he has not been sleeping well either. the doctor orders a test to determine if your grandpa has sleep apnea. what is the name of this test?

• pulmonary function test
• ventilation/perfusion scan
• polysomnography
• oximetry

Analyze Question 30

The patient is suspected of having pneumonia, and the doctor wants to order a radiographic test to obtain anterior, posterior, and lateral views of the lungs.

• A chest X-ray (CXR) is the standard, initial radiographic imaging test used to visualize the lungs from these angles (anterior-posterior and lateral views) to identify infiltrates or consolidation associated with pneumonia.
• A ventilation/perfusion (V/Q) scan is used primarily to evaluate for pulmonary embolism.
• Thoracentesis is an invasive procedure to remove fluid from the pleural space, not an imaging test.
• Pulmonary angiography is an imaging test of the blood vessels of the lungs, not a standard test for pneumonia.

Using the Clinical Case Analysis knowledge point, we determine that a chest X-ray (CXR) is the correct diagnostic imaging modality.

Analyze Question 31

The patient's grandfather is suspected of having sleep apnea due to loud snoring and poor sleep quality. The doctor orders a test to confirm this diagnosis.

• Polysomnography (often called a sleep study) is the comprehensive, gold-standard diagnostic test used to monitor and record physiological data during sleep to diagnose sleep disorders like sleep apnea.
• Pulmonary function tests measure lung volumes and airflow, not sleep patterns.
• A ventilation/perfusion scan evaluates lung blood flow and airflow.
• Oximetry measures oxygen saturation but is not a comprehensive diagnostic test for sleep apnea on its own.

Using the Clinical Case Analysis knowledge point, we determine that polysomnography is the correct diagnostic test.
