Crossfit Health, Safety, and Risk 4

Question 1

What is the recommended compression-to-ventilation ratio for adult CPR when performed by a single trained rescuer?

Accepted Answer

30:2

Answer

Current American Heart Association guidelines specify a 30:2 compression-to-ventilation ratio for single-rescuer adult CPR.

Question 2

A coach notices an athlete hyperventilating and displaying carpopedal spasms after an intense set. This presentation is MOST consistent with:

Accepted Answer

Hypocapnia-induced respiratory alkalosis from hyperventilation

Answer

Hyperventilation causes excessive CO2 exhalation, raising blood pH (respiratory alkalosis), which triggers muscle spasms in the hands and feet.

Question 3

Under which circumstance should an AED NOT be used on a victim?

Accepted Answer

When the victim is lying on a wet surface that cannot be cleared

Answer

Using an AED on a wet surface risks electrical conduction to rescuers; the victim must be moved to a dry area before AED use.

Question 4

What distinguishes exertional heat stroke from heat exhaustion?

Accepted Answer

Heat stroke involves core body temperature above 104°F (40°C) with central nervous system dysfunction

Answer

Exertional heat stroke is defined by a core temperature exceeding 104°F combined with neurological symptoms such as confusion or loss of consciousness.

Question 5

Which of the following is an example of a contraindication that would require a coach to defer a new athlete's participation until medical clearance is obtained?

Accepted Answer

Unstable angina diagnosed within the past month
