CPA Health Assessment & First Aid 3 — Questions and Answers
Question 1: A petroleum worker on a summer job site stops sweating, has hot dry skin, and a body temperature of 104°F. This best describes:
- Heat cramps
- Heat exhaustion
- Heat stroke (Correct answer)
- Mild dehydration
Correct answer: Heat stroke
Heat stroke involves a failure of the body's cooling system, leading to elevated temperature, cessation of sweating, and altered mental status — a life-threatening emergency.
Question 2: The immediate first aid priority for a heat stroke victim in a petroleum field setting is:
- Give cool fluids by mouth and rest the victim in shade
- Rapidly cool the body using ice packs or cool water immersion and call EMS (Correct answer)
- Apply a light blanket and monitor pulse
- Administer aspirin or ibuprofen to lower temperature
Correct answer: Rapidly cool the body using ice packs or cool water immersion and call EMS
Rapid cooling is critical for heat stroke because prolonged elevated body temperature causes irreversible organ damage and death.
Question 3: What is the correct rate of chest compressions during adult CPR according to current American Heart Association 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
Current AHA guidelines recommend 100–120 compressions per minute to maintain effective cardiac output during CPR.
Question 4: When a victim has a suspected spinal injury in a petroleum field accident, head and neck movement should be:
- Gently flexed to open the airway
- Minimized and stabilized in a neutral position (Correct answer)
- Rotated to assess neck injury severity
- Allowed freely to check range of motion
Correct answer: Minimized and stabilized in a neutral position
Unnecessary movement of the head and neck in a suspected spinal injury can worsen cord damage, so manual stabilization in a neutral position is essential.
Question 5: Which type of bleeding is characterized by bright red blood spurting in pulses from a wound?
- Capillary bleeding
- Venous bleeding
- Arterial bleeding (Correct answer)
- Internal bleeding
Correct answer: Arterial bleeding
Arterial blood is oxygenated (bright red) and flows under high pressure, causing it to spurt rhythmically with each heartbeat.
Question 6: What is the correct depth of chest compressions for an average adult during CPR?
- At least 1 inch
- At least 2 inches (5 cm) (Correct answer)
- Exactly 1.5 inches
- At least 3 inches
Correct answer: At least 2 inches (5 cm)
AHA guidelines specify compressing the adult chest at least 2 inches (5 cm) but not more than 2.4 inches to generate adequate blood flow.
Question 7: A tourniquets applied to a limb should be documented with:
- The victim's name only
- The time of application written on the tourniquet or the victim's forehead (Correct answer)
- The type of material used
- The blood type of the victim
Correct answer: The time of application written on the tourniquet or the victim's forehead
Recording the exact time of tourniquet application is critical because medical personnel must know how long the limb has been without circulation to prevent permanent damage.
