  1. Frostbite on a worker's fingers should be managed in the field by:

    Answer: Do not rewarm in the field if refreezing is possible; protect, insulate, and transport

    Refreezing thawed tissue causes worse damage than leaving it frozen; field rewarming is only appropriate when refreezing can be definitively prevented.

  2. A worker has ingested an unknown chemical. After calling Poison Control (1-800-222-1222), what information is most critical to provide?

    Answer: The product name, quantity ingested, and time of ingestion

    Product name, amount, and time of ingestion allow Poison Control to determine the toxicity and recommend the correct treatment.

  3. Which symptom combination is associated with organophosphate (pesticide) poisoning in agricultural or landscaping workers?

    Answer: Excessive secretions, pinpoint pupils, muscle twitching, and bradycardia

    Organophosphate poisoning causes the SLUDGE syndrome: Salivation, Lacrimation, Urination, Defecation, GI distress, and Emesis, along with pinpoint pupils and bradycardia.

  4. An OFA responder manages a worker with suspected inhalation of welding fumes showing coughing and chest tightness. The correct action is:

    Answer: Remove from exposure, provide fresh air, keep the worker calm, and arrange medical evaluation

    Inhalation injuries require immediate removal from the source, fresh air, rest, and medical evaluation as delayed pulmonary edema can develop hours later.

  5. Which temperature reading defines heat stroke in occupational first aid guidelines?

    Answer: Core temperature at or above 104°F (40°C) with altered mental status

    A core body temperature at or above 104°F (40°C) combined with altered mental status defines heat stroke, distinguishing it from heat exhaustion.

  6. Lightning strike victims at a worksite who appear unresponsive should be prioritized for:

    Answer: Immediate CPR if pulseless, as lightning victims are safe to touch and have high survival rates with prompt resuscitation

    Lightning victims are safe to touch immediately and have among the highest survival rates of any cardiac arrest cause when CPR is started promptly.
