OFA Injury Management & Workplace Safety Procedures 5 — Questions and Answers
Question 1: A worker receives a chemical splash to the eyes. The correct first aid treatment is to irrigate the eyes with water for a minimum of:
- 1 to 2 minutes
- 5 minutes
- 15 to 20 minutes (Correct answer)
- 30 seconds then cover with a pad
Correct answer: 15 to 20 minutes
Eyes exposed to chemical splashes must be flushed continuously with water for at least 15–20 minutes to effectively dilute and remove the chemical.
Question 2: Which of the following represents the correct compression-to-ventilation ratio for adult CPR performed by a single rescuer?
- 15 compressions to 2 breaths
- 30 compressions to 2 breaths (Correct answer)
- 5 compressions to 1 breath
- 30 compressions to 1 breath
Correct answer: 30 compressions to 2 breaths
Current AHA guidelines specify a 30:2 compression-to-ventilation ratio for single-rescuer adult CPR.
Question 3: When assessing a workplace injury using the primary survey, what does the 'C' in the ABCDE approach stand for?
- Circulation
- Cervical spine / Catastrophic hemorrhage (Correct answer)
- Consciousness
- Compression
Correct answer: Cervical spine / Catastrophic hemorrhage
In the ABCDE primary survey, 'C' stands for Cervical spine protection and Catastrophic hemorrhage control.
Question 4: A worker develops frostbite on their fingers after working outdoors in extreme cold. The OFA attendant should:
- Rub the affected fingers vigorously to restore circulation
- Have the worker walk around to generate body heat
- Protect the area from further cold and avoid rewarming if refreezing is possible (Correct answer)
- Place the fingers directly into hot water to rapidly rewarm the tissue
Correct answer: Protect the area from further cold and avoid rewarming if refreezing is possible
Frostbitten tissue should not be rewarmed in the field if there is a risk of refreezing, as thaw-refreeze cycles cause severe tissue damage.
Question 5: A worker is found in a confined space, unresponsive. The FIRST action the OFA attendant should take is to:
- Enter immediately and begin rescue breathing
- Call for help and do NOT enter until the space is confirmed safe (Correct answer)
- Lower a rope to pull the worker out by any means
- Administer oxygen through the entry point
Correct answer: Call for help and do NOT enter until the space is confirmed safe
Confined space rescues require atmospheric testing and standby rescue procedures; entering without confirmation exposes rescuers to the same hazard that incapacitated the worker.
Question 6: Which of the following correctly describes the difference between an open and closed fracture?
- An open fracture is less painful than a closed fracture
- An open fracture involves a break in the skin near or at the fracture site; a closed fracture does not (Correct answer)
- A closed fracture requires surgery while an open fracture heals on its own
- Open fractures only occur in the lower extremities
Correct answer: An open fracture involves a break in the skin near or at the fracture site; a closed fracture does not
An open (compound) fracture has a wound in the skin near the fracture, creating a high risk of infection compared to a closed fracture.
Question 7: What is the recommended rate of chest compressions during adult CPR according to current AHA guidelines?
- 60–80 compressions per minute
- 80–100 compressions per minute
- 100–120 compressions per minute (Correct answer)
- 120–140 compressions per minute
Correct answer: 100–120 compressions per minute
The AHA recommends a compression rate of 100–120 per minute to optimize cardiac output during CPR.
