First Aid Practice Test: Video 3 Answers (24 Questions) — Questions and Answers

Question 1: What does the term 'avulsion' describe in the context of wound care?

A wound caused by a puncturing object
A wound caused by a sharp, clean cut
A wound where a flap of skin or tissue is torn away (Correct answer)
A bruise beneath unbroken skin

Correct answer: A wound where a flap of skin or tissue is torn away

An avulsion is a traumatic wound in which a piece of skin or tissue is forcibly torn away from its normal position.

Question 2: A wound is spurting bright red blood in pulses. This indicates injury to which type of blood vessel?

Artery (Correct answer)
Capillary
Vein
Lymphatic vessel

Correct answer: Artery

Bright red blood spurting in pulses is characteristic of arterial bleeding due to high pressure from the heart.

Question 3: Which wound type is most associated with jagged, irregular edges and caused by blunt force trauma?

Incision
Laceration (Correct answer)
Abrasion
Puncture

Correct answer: Laceration

Lacerations are irregular tears in the skin typically caused by blunt force, resulting in jagged wound edges that may be difficult to close.

Question 4: A rescuer notices bright red blood spurting rhythmically from a wound on the forearm. This pattern indicates bleeding from which type of vessel?

Lymphatic vessel
Artery (Correct answer)
Capillary
Vein

Correct answer: Artery

Arterial bleeding produces bright red, spurting blood that pulses in rhythm with the heartbeat due to high pressure within arteries.

Question 5: When taking a severed finger—or part of one—to the emergency room, how should you carry it?

Put the severed part directly in water
Place it in a clean plastic bag, pack the bag in ice (Correct answer)
Use dry ice to freeze severed part
You should not carry it but dispose of it in seal proof bag

Correct answer: Place it in a clean plastic bag, pack the bag in ice

To maximize the chance of reattachment, a severed body part must be preserved correctly. It should be placed in a clean plastic bag to keep it sterile and prevent direct contact with water, then that bag should be packed in ice. This method keeps the tissue cold to slow degradation without causing direct freezing damage or waterlogging.

Question 6: When applying a tourniquet to control severe limb bleeding at work, where should it be placed?

Directly over the wound
2–3 inches below the wound
2–3 inches above the wound (Correct answer)
At the joint nearest the wound

Correct answer: 2–3 inches above the wound

A tourniquet must be placed 2–3 inches above (proximal to) the wound to effectively cut off blood flow to the injured area.

Question 7: A coworker has a suspected spinal injury after a fall. What is the MOST important first aid principle?

Perform range-of-motion checks on the neck
Have them walk to a safe area to assess injuries
Sit them upright to help them breathe
Do not move them unless they are in immediate danger (Correct answer)

Correct answer: Do not move them unless they are in immediate danger

Moving a victim with a suspected spinal injury can cause permanent paralysis, so immobilization and waiting for EMS is critical.

Question 8: What does the acronym RICE stand for in the treatment of a soft tissue workplace injury?

Reduce, Ice, Circulation, Exercise
Rotate, Immobilize, Cool, Elevate
Rest, Ice, Compression, Elevation (Correct answer)
Rest, Immobilize, Compress, Examine

Correct answer: Rest, Ice, Compression, Elevation

RICE (Rest, Ice, Compression, Elevation) is the standard first aid protocol for sprains, strains, and contusions.

Question 9: What breathing, circulatory, and airway techniques are appropriate for performing CPR?

Back, circulation, airway
Airway, breathing, circulation
Chest compressions, airway, breathing (Correct answer)
Airway, breastbone, chest

Correct answer: Chest compressions, airway, breathing

The current recommended sequence for performing CPR for adults, according to major organizations like the American Heart Association, is C-A-B: Chest compressions first, followed by opening the Airway, and then providing Breaths. This prioritization ensures that blood circulation is established quickly to vital organs.

Question 10: What should you do if the AED delivers a shock to a cardiac arrest victim?

Remove the AED pads and call 911
Wait 2 minutes before resuming CPR
Check for a pulse for 60 seconds
Immediately resume CPR starting with chest compressions (Correct answer)

Correct answer: Immediately resume CPR starting with chest compressions

After any AED shock, CPR should be resumed immediately starting with chest compressions without checking for a pulse.

Question 11: What is the recommended rate of chest compressions per minute for adult CPR?

80 to 100 compressions per minute
100 to 120 compressions per minute (Correct answer)
More than 120 compressions per minute
60 to 80 compressions per minute

Correct answer: 100 to 120 compressions per minute

The AHA recommends a compression rate of 100–120 per minute to maintain adequate blood flow during CPR.

Question 12: When performing CPR on an adult, what is the correct hand placement for chest compressions?

On the lower half of the sternum, center of the chest (Correct answer)
On the upper half of the sternum
On the left side of the chest over the heart
On the abdomen just below the ribcage

Correct answer: On the lower half of the sternum, center of the chest

Compressions should be delivered on the lower half of the sternum, centered on the chest, to effectively pump the heart.

Question 13: How long should you check for a pulse before concluding there is none and starting CPR?

5 seconds
30 seconds
15–20 seconds
No more than 10 seconds (Correct answer)

Correct answer: No more than 10 seconds

You should check for a carotid pulse for no more than 10 seconds before starting chest compressions.

Question 14: What does the 'C-A-B' sequence stand for in current CPR guidelines?

Compressions, Airway, Breathing (Correct answer)
Compressions, Assessment, Bleeding
Check, Assess, Begin
Call, Airway, Breathe

Correct answer: Compressions, Airway, Breathing

The American Heart Association updated CPR sequence to C-A-B (Compressions, Airway, Breathing) to prioritize chest compressions.

Question 15: Which of the following is a sign that a tick bite may be causing Lyme disease?

Immediate severe pain at the bite site
A black spot at the center of a white rash
A bulls-eye (ring-shaped) rash around the bite (Correct answer)
Rapid swelling and hives

Correct answer: A bulls-eye (ring-shaped) rash around the bite

The bull's-eye rash (erythema migrans) is a hallmark early sign of Lyme disease and requires prompt medical evaluation.

Question 16: Which of the following best describes the position of a bitten limb while awaiting help after a snakebite?

Elevated above heart level
Below heart level
At heart level and immobilized (Correct answer)
Wrapped tightly with a bandage

Correct answer: At heart level and immobilized

Keeping the bitten limb at heart level and immobilized slows venom spread without cutting off circulation.

Question 17: A child may have swallowed cleaning product. The child appears alert with no immediate distress. What should you do FIRST?

Wait 30 minutes to see if symptoms develop
Call Poison Control at 1-800-222-1222 immediately (Correct answer)
Give the child a large glass of milk
Take the child to the ER without calling anyone

Correct answer: Call Poison Control at 1-800-222-1222 immediately

Poison Control should be called immediately for guidance, even if the child shows no symptoms yet.

Question 18: Which symptom is a common sign of carbon monoxide poisoning?

Cherry-red skin and headache (Correct answer)
Yellow skin and nausea
Blue lips and chest pain
Rash and fever

Correct answer: Cherry-red skin and headache

Cherry-red skin and headache are classic signs of carbon monoxide poisoning due to the gas binding to hemoglobin.

Question 19: How should you remove a bee stinger from the skin?

Squeeze and pull it with tweezers
Scrape it away with a credit card or fingernail (Correct answer)
Leave it in place and apply ice
Burn it out with a heated needle

Correct answer: Scrape it away with a credit card or fingernail

Scraping the stinger sideways avoids squeezing the venom sac, which would inject more venom.

Question 20: When applying a tourniquet to control severe limb bleeding, how far above the wound should it be placed?

2–3 inches above the wound (Correct answer)
At least 6 inches above the wound
1–2 inches above the wound
Directly on the wound

Correct answer: 2–3 inches above the wound

A tourniquet should be placed 2–3 inches above the wound, never directly on a joint, to effectively compress the artery.

Question 21: A victim in shock should be positioned in which way, assuming no spinal injury?

On their side in the recovery position
Sitting upright at 90 degrees
Prone (face down)
Lying flat with legs elevated about 12 inches (Correct answer)

Correct answer: Lying flat with legs elevated about 12 inches

Elevating the legs approximately 12 inches while the victim lies flat helps return blood to vital organs and improve circulation.

Question 22: What does the acronym 'RICE' stand for in wound and injury first aid?

Reduce, Immobilize, Cool, Examine
Rest, Ice, Compression, Elevation (Correct answer)
Restrict, Ice, Cover, Evaluate
Rinse, Inspect, Clean, Elevate

Correct answer: Rest, Ice, Compression, Elevation

RICE (Rest, Ice, Compression, Elevation) is the standard initial treatment protocol for soft-tissue injuries to reduce swelling and pain.

Question 23: If a wound dressing becomes soaked with blood, what is the correct action?

Add more dressings on top without removing the original (Correct answer)
Apply ice directly to the soaked dressing
Remove the soaked dressing and replace it with a fresh one
Release pressure for 5 minutes to allow clotting

Correct answer: Add more dressings on top without removing the original

Adding more dressings on top preserves the clot that has begun to form; removing the original dressing can disrupt clotting and worsen bleeding.

Question 24: Which sign best distinguishes arterial bleeding from venous bleeding?

Venous bleeding is always more life-threatening
Venous blood spurts forcefully in pulses
Arterial blood is bright red and spurts with each heartbeat (Correct answer)
Arterial blood is darker red and flows steadily

Correct answer: Arterial blood is bright red and spurts with each heartbeat

Arterial blood is bright red and spurts rhythmically because it is under high pressure from the heart's pumping action.
