Rosh Pediatrics Practice Exam

What additional test might be beneficial if there are concerns about complications such as peritonsillar abscess?

1. Chest X-ray

2. Ultrasound of the neck

3. CT scan of the abdomen

4. Blood tests for liver function

The correct answer is: Ultrasound of the neck

The recommended additional test in the context of concerns about complications like a peritonsillar abscess is an ultrasound of the neck. This imaging technique is particularly useful because it allows for real-time visualization of the tonsils and surrounding tissues. An ultrasound can effectively identify fluid collections, which may indicate the presence of an abscess, as well as other anatomical issues in the neck region. Ultrasound is advantageous in this scenario due to its non-invasive nature, absence of ionizing radiation, and ability to provide immediate results. Early identification of an abscess is crucial, as it may require drainage and prompt treatment to prevent further complications, such as airway obstruction or spread of infection. In contrast, while a chest X-ray can help rule out pulmonary complications, it doesn’t provide relevant information regarding the tonsils or potential abscess formations. A CT scan of the abdomen would be unrelated to throat issues and focuses on a different body area, which is not useful for evaluating peritonsillar abscesses. Blood tests for liver function also do not provide any relevant information regarding complications in the neck region.
