Hi Danielle! I’m jumping in because Helen’s response was cut off when the forum closed on Sunday – below are the responses from both Helen and Jessica.
For the PCS exam, it is likely best to stick to the APPT CPG. I think that concussion guidelines are somewhat fluid and tend to evolve frequently, leading to some gray areas in terms of best practice. During the exam, stay focused on the question stem and try not to overthink the question.
Of note, when Jessica and I recently took our respective MOSC recertification exams, they stuck very closely to the CPGs, so that is likely good advice for the initial certification exam, as well!
