Advanced Trauma Life Support (ATLS) Practice Exam

In trauma cases, assessing a patient's coagulation status is critical, as coagulopathy can significantly affect management and outcomes. The complete blood count (CBC) along with coagulation studies such as Prothrombin Time (PT), Activated Partial Thromboplastin Time (aPTT), and possibly Thrombin Time (TT) provides valuable information about the patient's ability to form clots.

A CBC can reveal the platelet count and hemoglobin levels, while coagulation tests assess the functionality of the clotting cascade and help identify any bleeding disorders or abnormalities in the patient's coagulation profile. This information is vital in trauma care, where bleeding control and the risk of hemorrhagic shock are major concerns.

Other options, while potentially useful in different clinical contexts, do not provide the immediate insights needed to evaluate coagulation status in a trauma setting. For instance, a nephrology panel assesses kidney function and related metabolic parameters, which are not directly related to coagulation analysis. A urine toxicology screen detects drugs or toxins but does not provide any information about the patient's ability to clot. Lastly, a pregnancy screen, while important in certain scenarios, does not have any relevance to coagulation status. Thus, focusing on CBC and coagulation tests directly
