What is the difference between collaboration and teamwork? (Select All that Apply.)

Rationale:
A. Epidural hematomas often present with a “lucid interval,” where the patient initially loses consciousness, briefly regains it, and then deteriorates rapidly. CT imaging typically shows a biconvex (lens-shaped) hematoma. In this case, CT was normal, and the patient remained unconscious, making epidural hematoma less likely.

B. Subarachnoid hemorrhage usually presents with sudden severe headache, nausea, vomiting, and neurological deficits. CT scans are generally positive in acute cases. The absence of CT findings and persistent unconsciousness make this diagnosis unlikely.

C. Subdural hematomas can present with delayed symptoms, but they are usually visible on CT imaging as crescent-shaped lesions. A normal CT scan reduces the likelihood of an acute subdural hematoma.

D. Diffuse axonal injury (DAI) results from shearing forces during high-velocity trauma, causing widespread damage to axons. DAI often leads to prolonged unconsciousness without specific findings on initial CT scans. The patient’s persistent coma, GCS ≤8, and normal CT are classic features of DAI. MRI may later reveal axonal injury not visible on CT.

Rationale:

A. While building rapport is important for overall patient care, it is not part of the primary function of triage in the emergency department. Triage focuses on rapidly assessing urgency rather than forming long-term relationships.

B. These interventions may occur after triage for patients who require immediate care, but they are not core components of the triage process itself. Triage is about prioritization, not initiating treatment.

C. Although triage includes a brief assessment, a full physical examination for abnormalities is generally done after triage. Triage is a rapid evaluation, not a detailed diagnostic assessment.

D. Triage involves rapidly assessing the patient’s condition using available information, such as history, presenting complaints, age, vital signs, and observable signs of distress, to determine urgency. This allows the ED to prioritize patients who need immediate intervention while safely delaying care for less urgent cases.
