Trauma Nurse Core Course (TNCC) Practice Exam 2025 - Free Practice Questions and Study Guide

A young male with severe lower abdominal pain and scrotal ecchymosis suggests a potential acute condition such as testicular torsion or an inguinal hernia, both of which require immediate evaluation. In this context, obtaining a urine sample through straight catheterization may not be the most appropriate initial intervention.

Questioning the order for straight catheterization is justified because, in the presence of testicular torsion, it's critical to avoid unnecessary manipulation of the urethra or bladder, which could exacerbate the condition or lead to further complications. Instead, non-invasive imaging or focused examinations should take precedence to diagnose the underlying issue rapidly.

In contrast, performing a FAST (Focused Assessment with Sonography for Trauma) exam is appropriate, as it can help assess for any internal bleeding or other complications. A CT scan can provide detailed imaging to rule out conditions like testicular torsion or other intra-abdominal issues, while ice and elevation of the scrotum can help alleviate swelling and manage pain, both of which are important supportive measures.
