NSC First Aid and CPR 3 — Questions and Answers
Question 1: What is the maximum depth of chest compressions recommended for an adult victim during CPR?
- 1 inch
- 1.5 inches
- At least 2 inches but no more than 2.4 inches (Correct answer)
- 3 inches
Correct answer: At least 2 inches but no more than 2.4 inches
NSC guidelines specify compressions should be at least 2 inches but not exceed 2.4 inches to be effective without causing injury.
Question 2: A person is bitten by a snake. Which action should you AVOID?
- Keep the victim calm and still
- Remove tight clothing near the bite
- Suck out the venom with your mouth (Correct answer)
- Call Poison Control or 9-1-1
Correct answer: Suck out the venom with your mouth
Sucking out venom is ineffective and can introduce bacteria into the wound; it is not recommended by any modern first aid guideline.
Question 3: What does the 'D' stand for in the NSC's emergency action steps (Check-Call-Care)?
- Danger (Correct answer)
- Defibrillation
- Documentation
- Diagnosis
Correct answer: Danger
Before providing care, you must Check the scene for Danger to ensure it is safe for both the rescuer and the victim.
Question 4: For an infant (under 1 year) who is unresponsive with no normal breathing, what compression depth is correct?
- About 1 inch (2.5 cm)
- About 1.5 inches (4 cm) (Correct answer)
- At least 2 inches
- Half the depth used for adults
Correct answer: About 1.5 inches (4 cm)
For infants, compressions should be about 1.5 inches (4 cm) deep, using two fingers on the center of the chest.
Question 5: A coworker suddenly collapses. After confirming unresponsiveness, what is your NEXT priority?
- Start chest compressions immediately
- Call or have someone call 9-1-1 (Correct answer)
- Open the airway and check breathing
- Retrieve the nearest AED
Correct answer: Call or have someone call 9-1-1
After confirming unresponsiveness, activating EMS (calling 9-1-1) is the next critical step to ensure advanced help is dispatched.
Question 6: Which type of wound is most at risk for tetanus infection?
- Clean superficial cut
- Puncture wound contaminated with dirt (Correct answer)
- Minor abrasion
- Paper cut
Correct answer: Puncture wound contaminated with dirt
Deep puncture wounds contaminated with soil, saliva, or feces carry the highest risk for tetanus because the bacteria thrive in low-oxygen environments.
Question 7: What is the primary purpose of applying direct pressure to a bleeding wound?
- To clean the wound
- To promote clotting and control blood loss (Correct answer)
- To numb the area
- To prevent infection
Correct answer: To promote clotting and control blood loss
Direct pressure slows blood flow to the wound, allowing the body's clotting mechanism to stop the bleeding.
