NFHS Foundational Concepts & Principles 2 — Questions and Answers
Question 1: Which of the following best describes why concussions are considered a 'functional' brain injury rather than a 'structural' one?
- Brain tissue is permanently destroyed at the cellular level
- Standard imaging like CT scans typically show no visible damage (Correct answer)
- The skull is fractured during the injury
- Bleeding occurs inside the brain cavity
Correct answer: Standard imaging like CT scans typically show no visible damage
Concussions cause chemical and metabolic disruption to brain function without detectable structural damage on standard imaging such as CT or MRI.
Question 2: Under the NFHS framework, who bears primary responsibility for implementing concussion protocols in high school sports?
- The team physician alone
- The school athletic director and coaching staff (Correct answer)
- The student-athlete's parents only
- State legislature committees
Correct answer: The school athletic director and coaching staff
Athletic directors and coaches are on the front lines of implementing concussion protocols and ensuring safe return-to-play procedures.
Question 3: The term 'neurometabolic cascade' in the context of concussion refers to:
- A rapid release of adrenaline following head impact
- A series of ionic and metabolic disturbances in the brain after injury (Correct answer)
- The brain's ability to immediately self-repair after trauma
- Swelling of brain tissue visible on imaging
Correct answer: A series of ionic and metabolic disturbances in the brain after injury
The neurometabolic cascade describes the complex chain of ionic flux, energy imbalance, and metabolic disruption that occurs in the brain following concussive impact.
Question 4: A student-athlete sustains a second concussion before fully recovering from the first. This scenario is most commonly referred to as:
- Chronic traumatic encephalopathy (CTE)
- Second-impact syndrome (Correct answer)
- Post-concussion syndrome
- Diffuse axonal injury
Correct answer: Second-impact syndrome
Second-impact syndrome occurs when a second concussion is sustained before the brain has fully recovered from a prior concussion, potentially causing rapid, catastrophic brain swelling.
Question 5: Which statement about concussion epidemiology in high school sports is most accurate?
- Concussions only occur in contact sports like football and wrestling
- Female athletes generally report lower concussion rates than male athletes in comparable sports
- Concussions are among the most commonly reported injuries in high school athletics (Correct answer)
- Concussion rates have remained unchanged over the past two decades
Correct answer: Concussions are among the most commonly reported injuries in high school athletics
Concussions are consistently reported as one of the most common injuries across high school sports, affecting athletes in a wide range of activities.
Question 6: Which of the following is the MOST accurate statement about concussion and loss of consciousness (LOC)?
- LOC must occur for an injury to be classified as a concussion
- LOC occurs in the majority of concussion cases
- LOC is relatively rare and occurs in a minority of concussions (Correct answer)
- LOC indicates a mild concussion with rapid recovery
Correct answer: LOC is relatively rare and occurs in a minority of concussions
Loss of consciousness occurs in less than 10% of concussions, meaning most concussions happen without any period of unconsciousness.
Question 7: The concept of 'when in doubt, sit them out' in NFHS concussion guidelines primarily reflects which principle?
- Athletic performance should never be interrupted
- Erring on the side of caution protects athlete safety when concussion is uncertain (Correct answer)
- Medical clearance is not required for return to play
- Coaches should make all final decisions about athlete health
Correct answer: Erring on the side of caution protects athlete safety when concussion is uncertain
This precautionary principle ensures athlete safety by removing from play any athlete suspected of having a concussion, even without confirmed diagnosis.
