OFA Emergency Response & Scene Assessment 5 — Questions and Answers
Question 1: When activating the emergency response system at a workplace, which action should be done SIMULTANEOUSLY with beginning first aid?
- Contacting the patient's next of kin
- Sending someone to call 911 and retrieve the AED (Correct answer)
- Completing an incident report form
- Notifying the patient's supervisor
Correct answer: Sending someone to call 911 and retrieve the AED
A bystander should be sent to call 911 and fetch the AED while the first aider begins care, maximizing the chance of survival.
Question 2: Which of the following BEST defines 'index of suspicion' in emergency scene assessment?
- A legal document outlining responder liability
- Anticipating hidden injuries based on mechanism of injury (Correct answer)
- A checklist used to evaluate patient vital signs
- The process of determining whether a scene is safe
Correct answer: Anticipating hidden injuries based on mechanism of injury
Index of suspicion means using the mechanism of injury to anticipate and look for injuries that may not be immediately obvious.
Question 3: Personal protective equipment (PPE) for an OFA first aider responding to a bleeding emergency should at minimum include:
- Hard hat and steel-toed boots
- Disposable gloves and eye protection (Correct answer)
- Full chemical hazmat suit
- N95 respirator and face shield only
Correct answer: Disposable gloves and eye protection
Disposable gloves and eye protection are the minimum standard PPE to protect against bloodborne pathogen exposure during bleeding emergencies.
Question 4: A worker is found conscious and breathing but confused after inhaling fumes. During scene assessment, which hazard must you address BEFORE providing care?
- Whether the worker has health insurance
- The source of fumes and ventilation of the area (Correct answer)
- The worker's employment status
- Whether supervisors have been notified
Correct answer: The source of fumes and ventilation of the area
Ongoing fume exposure endangers both the patient and responder; ensure ventilation or move to fresh air before treating the patient.
Question 5: The 'C' in the updated DRABC-C model used by some OFA programs stands for:
- Cervical spine control
- Catastrophic hemorrhage control (Correct answer)
- Cardiac monitoring
- Call for help
Correct answer: Catastrophic hemorrhage control
Modern protocols add 'C' for Catastrophic hemorrhage control before airway assessment, recognizing that massive bleeding can kill faster than airway compromise.
Question 6: After calling 911, an OFA responder's role in handoff to EMS is to:
- Step back completely and allow EMS to start from scratch
- Provide a concise verbal report including patient status and care given (Correct answer)
- Accompany the patient to the hospital
- Complete all documentation before speaking to paramedics
Correct answer: Provide a concise verbal report including patient status and care given
A concise handoff report (SAMPLE, vital signs, treatments given) ensures continuity of care and allows EMS to continue treatment without delay.
Question 7: During a scene assessment at a warehouse, you note a worker slumped over machinery with his arm still engaged. What must occur BEFORE you touch the patient?
- Complete the incident report
- De-energize and lock out the machinery (Correct answer)
- Check the patient's pulse
- Notify OSHA
Correct answer: De-energize and lock out the machinery
Machinery must be de-energized using lockout/tagout procedures before a responder approaches, preventing additional injury to the patient or responder.
