NSC First Aid and CPR 4 — Questions and Answers
Question 1: What is the recommended rate of chest compressions per minute for CPR?
- 60–80 per minute
- 80–100 per minute
- 100–120 per minute (Correct answer)
- 120–140 per minute
Correct answer: 100–120 per minute
CPR should be performed at a rate of 100 to 120 compressions per minute to optimize blood circulation.
Question 2: A victim has a chemical burn to the eye. What is the correct first aid?
- Cover the eye with a dry bandage
- Flush the eye with large amounts of water for at least 15–20 minutes (Correct answer)
- Apply burn cream directly to the eye
- Rub the eye to remove the chemical
Correct answer: Flush the eye with large amounts of water for at least 15–20 minutes
Immediate and prolonged irrigation with water is critical to dilute and remove the chemical from the eye.
Question 3: When is it appropriate to remove an embedded (impaled) object from a wound?
- Always, to stop bleeding
- Only if it is in the chest
- Only when it interferes with CPR (Correct answer)
- Never — stabilize and leave it in place
Correct answer: Only when it interferes with CPR
An impaled object should only be removed if it interferes with performing CPR; otherwise, stabilize it in place to prevent further injury.
Question 4: Which sign best distinguishes a stroke from other emergencies?
- Chest pain radiating to the arm
- Sudden facial drooping, arm weakness, or speech difficulty (Correct answer)
- Difficulty breathing and wheezing
- Slow, bounding pulse
Correct answer: Sudden facial drooping, arm weakness, or speech difficulty
The FAST acronym (Face drooping, Arm weakness, Speech difficulty, Time to call 9-1-1) identifies classic stroke signs.
Question 5: A victim is experiencing a diabetic emergency and is still conscious. What should you give them?
- Water only
- A sugary drink or glucose tablets (Correct answer)
- Insulin injection
- Salt tablets
Correct answer: A sugary drink or glucose tablets
A conscious diabetic victim showing signs of low blood sugar (hypoglycemia) should receive a fast-acting sugar source such as juice or glucose tablets.
Question 6: Which burn classification involves damage through all skin layers, possibly into muscle or bone?
- Superficial (first-degree)
- Partial thickness (second-degree)
- Full thickness (third-degree) (Correct answer)
- Subdermal (fourth-degree)
Correct answer: Full thickness (third-degree)
Full thickness (third-degree) burns destroy all layers of the skin and may involve underlying tissue, muscle, or bone.
Question 7: How long should you check for breathing before beginning CPR on an unresponsive adult?
- Up to 10 seconds (Correct answer)
- 30 seconds
- 1 minute
- 2 minutes
Correct answer: Up to 10 seconds
Check for breathing for no more than 10 seconds; if absent or only gasping, begin CPR immediately.
