Occupational First Aid Level 1 (OFA Level 1) — Questions and Answers

Question 1: Which of the following is a key part of workplace safety procedures?

Wait for an accident before taking action.
Avoid reporting hazards.
Conduct regular safety drills (Correct answer)
Ignore minor injuries.

Correct answer: Conduct regular safety drills

Conducting regular safety drills is a key part of effective workplace safety procedures. These drills allow employees to practice emergency responses, understand evacuation routes, and become familiar with safety equipment and protocols. This preparation ensures that in a real emergency, employees can react quickly and appropriately, minimizing risks and potential harm.

Question 2: At a multi-victim incident, the START triage system categorizes patients using which four colors?

Red, Yellow, Green, Black (Correct answer)
Red, Orange, Yellow, Black
Orange, Yellow, Green, Black
Red, Blue, Green, White

Correct answer: Red, Yellow, Green, Black

START triage uses Red (immediate), Yellow (delayed), Green (minor), and Black (expectant/deceased) to prioritize patients.

Question 3: An impaled object is found in a worker's thigh. What is the correct first-aid action?

Stabilize the object in place with bulky dressings and do not remove it (Correct answer)
Apply a tourniquet above the impaled object
Remove the object immediately to stop bleeding
Shorten the object if it is longer than 6 inches

Correct answer: Stabilize the object in place with bulky dressings and do not remove it

Impaled objects should never be removed in the field; stabilizing them prevents further injury and helps control bleeding.

Question 4: Why should you NOT remove the original dressing when blood soaks through it?

Removing it disturbs the clot forming beneath and restarts bleeding (Correct answer)
It is too painful for the victim
The wound may become contaminated
It may cause an allergic reaction

Correct answer: Removing it disturbs the clot forming beneath and restarts bleeding

The original dressing supports clot formation; removing it disrupts the clot and can significantly increase blood loss.

Question 5: Which factor MOST significantly affects the quality of technical outcomes in OFA practice?

The time of day
The practitioner's training, preparation, and attention to detail (Correct answer)
Speed of procedure completion
The brand of equipment

Correct answer: The practitioner's training, preparation, and attention to detail

Quality depends primarily on training, preparation, and attention to detail.

Question 6: When completing a workplace incident report after providing first aid, what information is MOST critical to include?

The injured worker's personal medical history
Only the treatment provided, to protect worker privacy
Time, location, description of injury, actions taken, and witnesses (Correct answer)
The supervisor's opinion of how the accident occurred

Correct answer: Time, location, description of injury, actions taken, and witnesses

A complete incident report must include the time, location, injury description, first aid actions taken, and witness information for safety and legal purposes.

Question 7: The 'look, listen, and feel' assessment technique is used to evaluate which patient parameter?

Presence and adequacy of breathing (Correct answer)
Level of consciousness
Adequacy of circulation
Skin color and temperature

Correct answer: Presence and adequacy of breathing

Looking for chest rise, listening for breath sounds, and feeling for air movement against the cheek together confirm whether a patient is breathing adequately.

Question 8: Why should a first aider avoid moving an injured person unnecessarily?

Because it can worsen their injuries (Correct answer)
Because the scene becomes too quiet.
Because it delays professional response.
Because it confuses the bystanders.

Correct answer: Because it can worsen their injuries

Moving an injured person unnecessarily can significantly worsen their injuries, especially if there are suspected spinal, head, or bone fractures. Such movement could cause further damage to tissues, nerves, or blood vessels, leading to increased pain or more severe complications. It is crucial to keep the person still and comfortable unless they are in immediate danger.

Question 9: Which splinting principle ensures the splint is applied correctly?

Splint should be tight enough to restrict all circulation
Pad the splint only at the fracture site
Immobilize the joint above AND below the suspected fracture site (Correct answer)
Splint only the joint above the fracture

Correct answer: Immobilize the joint above AND below the suspected fracture site

A properly applied splint must immobilize the joints both above and below the fracture to prevent movement at the fracture site.

Question 10: A first aider can be held legally protected from liability in most U.S. states when providing emergency care in good faith under:

Workers' Compensation statutes
The Occupational Safety and Health Act
The Emergency Medical Treatment Act
Good Samaritan laws (Correct answer)

Correct answer: Good Samaritan laws

Good Samaritan laws protect trained first aiders who provide reasonable emergency care in good faith without gross negligence.

Question 11: A worker is unresponsive and not breathing normally. You have started CPR. When the AED arrives, you should:

Finish a full 2-minute CPR cycle before using the AED
Use the AED only if CPR has failed for 5 minutes
Turn on the AED, apply pads, and minimize interruptions to CPR (Correct answer)
Stop CPR, apply pads, then turn on the AED

Correct answer: Turn on the AED, apply pads, and minimize interruptions to CPR

Turn on the AED and apply pads as quickly as possible while minimizing any interruptions to chest compressions.

Question 12: When providing rescue breaths with a pocket mask, how should the rescuer create a seal?

Use the mask only over the nose while pinching the mouth closed
Place the narrow end over the chin and breathe through the nose
Place the mask over the nose and mouth and press firmly around the edges (Correct answer)
Hold the mask loosely to allow exhaled air to escape

Correct answer: Place the mask over the nose and mouth and press firmly around the edges

A proper mask seal over the nose and mouth with firm pressure around the edges prevents air leaks and ensures effective ventilation.

Question 13: What should you do if bleeding soaks through the bandage?

Remove the bandage and apply a new one.
Wrap the wound tightly with tape.
Apply more dressings on top and continue pressure (Correct answer)
Do nothing and wait for it to stop.

Correct answer: Apply more dressings on top and continue pressure

If bleeding soaks through the initial bandage, it indicates that the pressure might not be sufficient or the bleeding is severe. The correct action is to apply additional clean dressings directly on top of the soaked ones and continue to apply firm, direct pressure. Removing the original bandage can disrupt the clotting process and worsen bleeding.

Question 14: What is the hallmark sign of heat stroke that distinguishes it from heat exhaustion?

Altered mental status (confusion, disorientation) and hot skin (Correct answer)
Muscle cramps with normal mental status
Nausea and mild dizziness with normal temperature
Profuse sweating and cold, clammy skin

Correct answer: Altered mental status (confusion, disorientation) and hot skin

Heat stroke is a life-threatening emergency characterized by a high body temperature and altered mental status, requiring immediate aggressive cooling.

Question 15: What is the primary purpose of wound irrigation in first aid?

To stop arterial bleeding
To remove debris and reduce the risk of infection (Correct answer)
To promote faster clotting
To numb the wound for pain relief

Correct answer: To remove debris and reduce the risk of infection

Irrigation with clean water or saline flushes out contaminants and bacteria, significantly reducing the risk of wound infection.

Question 16: 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 17: Which risk management approach is MOST effective for OFA professionals when evaluating potential workplace hazards?

Delegating all safety decisions to management
Reactive analysis after incidents occur
Relying solely on historical accident data
Proactive hazard identification and assessment (Correct answer)

Correct answer: Proactive hazard identification and assessment

Proactive hazard identification and assessment allows professionals to identify and mitigate risks before incidents occur.

Question 18: Which condition is a contraindication to inserting an oropharyngeal airway (OPA)?

The patient is deeply unconscious
The patient has dentures that have been removed
The patient is conscious or semi-conscious with a gag reflex (Correct answer)
The patient has no gag reflex

Correct answer: The patient is conscious or semi-conscious with a gag reflex

An OPA must never be used in a conscious or semi-conscious patient who has a gag reflex, as it will trigger vomiting and risk aspiration.

Question 19: In the context of AED use, what does the term 'shockable rhythm' refer to?

A rhythm present only in children under 8
Any heart rhythm detected by the AED
Ventricular fibrillation or pulseless ventricular tachycardia (Correct answer)
Asystole or pulseless electrical activity

Correct answer: Ventricular fibrillation or pulseless ventricular tachycardia

Shockable rhythms are ventricular fibrillation (VF) and pulseless ventricular tachycardia (pVT), both of which can be converted by defibrillation.

Question 20: When applying a tourniquet on a limb, how far above the wound should it be placed?

As close to the joint as possible
At least 6 inches above the wound
2–3 inches (5–7 cm) above the wound (Correct answer)
Directly over the wound

Correct answer: 2–3 inches (5–7 cm) above the wound

A tourniquet should be applied 2–3 inches above the wound to effectively stop arterial blood flow without unnecessary tissue damage.

Question 21: Why should proper lifting techniques be taught at the workplace?

To reduce training time.
To increase lifting speed.
To prevent back and muscle injuries (Correct answer)
To make employees stronger.

Correct answer: To prevent back and muscle injuries

Proper lifting techniques should be taught at the workplace to prevent common back and muscle injuries. Incorrect lifting can lead to strains, sprains, and more severe musculoskeletal disorders, causing pain and lost work time. Training employees to lift with their legs and maintain a straight back significantly reduces these risks, promoting a safer working environment.

Question 22: A worker reports hearing a 'pop' in the ankle followed by immediate swelling and inability to bear weight. This most likely indicates:

An infection that developed rapidly
A grade III (severe) sprain or fracture requiring medical evaluation (Correct answer)
Minor muscle fatigue
A mild bruise

Correct answer: A grade III (severe) sprain or fracture requiring medical evaluation

An audible pop, rapid swelling, and inability to bear weight suggest a severe sprain or fracture requiring X-ray and medical evaluation.

Question 23: What is the normal resting respiratory rate for an adult?

6–10 breaths per minute
30–40 breaths per minute
22–28 breaths per minute
12–20 breaths per minute (Correct answer)

Correct answer: 12–20 breaths per minute

A normal adult resting respiratory rate is 12–20 breaths per minute; rates outside this range may indicate a breathing problem.

Question 24: Which of the following correctly describes the management of a nosebleed (epistaxis) in the workplace?

Tilt the head back and apply pressure to the bridge
Apply ice directly inside the nostril
Have the victim sit leaning slightly forward and pinch the soft part of the nose for 10–15 minutes (Correct answer)
Pack the nostril tightly with cotton and have the victim lie flat

Correct answer: Have the victim sit leaning slightly forward and pinch the soft part of the nose for 10–15 minutes

Leaning slightly forward prevents swallowing blood; pinching the soft part of the nose (not the bridge) for 10–15 minutes allows clotting.

Question 25: Which sign indicates that a dressing over a wound is no longer effective and needs to be changed?

The victim reports mild discomfort
Blood has soaked through the outer layer of the dressing (Correct answer)
The bandage has been in place for more than 1 hour
The dressing is slightly warm to the touch

Correct answer: Blood has soaked through the outer layer of the dressing

Strike-through (blood soaking through to the outer layer) indicates the dressing is saturated; add additional dressings on top and continue pressure.
