What is the primary focus of a standard FAST examination?

The primary focus of a standard FAST (Focused Assessment with Sonography for Trauma) examination is to evaluate for free intraperitoneal fluid. This ultrasound examination is typically performed in trauma settings to quickly assess patients for internal bleeding, particularly in the abdominal cavity. By detecting the presence of fluid, medical personnel can determine if there is significant organ injury that may require surgical intervention.

The FAST exam is a rapid, non-invasive procedure that provides critical information swiftly, facilitating timely decision-making in emergency care. It specifically targets areas such as the pericardial space and abdominal quadrants to find fluid accumulation, which can be indicative of hemorrhage.

Other options, while related to medical assessments, do not align with the primary goal of the FAST examination. Assessing bone density, searching for fractures, and measuring heart function involve different diagnostic techniques and objectives that are not the main focus of FAST.
