EFA exit exam questions and answers — Set 16 — Elementary First Aid

Set 16 of the Elementary First Aid (EFA) exit exam bank — 30 of 1185 questions, with the correct option marked and a one-line explanation for every one. Read it end to end, jump to a single set, or search it — then sit the same bank as a timed paper. The real DG Shipping exit exam is 30 marks with 15 to pass.

These are the bank's original groupings. Practising deals the whole bank out again every time you reshuffle, so a practice “Set 3” is a different 30 questions each time — the set numbers below are the source file's, and are only used here so the key stays navigable. Options are listed in their original order with fixed letters; when you practise, those move too.

Set 16 — 30 EFA exit exam questions with answers

1. The CPR ratio of chest compressions to rescue breaths for an adult is ____.

  • A. 30 breaths : 2 compressions
  • B. 30 compressions : 2 breaths
  • C. 20 breaths : 2 compressions
  • D. 15 breaths : 1 compression
Answer: B — 30 compressions : 2 breaths
For adult CPR the recommended cycle is 30 chest compressions followed by 2 rescue breaths, repeated without long interruptions. Compressions maintain blood flow to the brain and heart, so they make up most of each cycle.

2. When flushing one eye that has been exposed to a chemical, the injured eye should be ____.

  • A. At a lower level than the good eye
  • B. At a higher level than the good eye
  • C. At the same level as the good eye
  • D. Kept closed during flushing
Answer: A — At a lower level than the good eye
The head is tilted so the injured eye is lowermost and water flows from the inner corner outwards. This prevents contaminated water running into the good eye. Flush for at least 15-20 minutes.

3. A person who is severely allergic to certain triggers should always carry ____.

  • A. Insulin
  • B. Hydroxychloroquine
  • C. Aspirin
  • D. Adrenaline
Answer: D — Adrenaline
Adrenaline (epinephrine), usually in an auto-injector, is the emergency treatment for anaphylaxis. It quickly reverses airway swelling and low blood pressure, so people with severe allergies are advised to carry it at all times.

4. To check for normal breathing in an unconscious casualty, you should look, listen and feel for no more than ____.

  • A. 5 seconds
  • B. 10 seconds
  • C. 15 seconds
  • D. 20 seconds
Answer: B — 10 seconds
After opening the airway, the rescuer looks, listens and feels for normal breathing for no more than 10 seconds. If breathing is absent or abnormal, CPR is started immediately to avoid delay.

5. What is the meaning of first aid?

  • A. Completing a primary survey
  • B. The first help given to an accident victim or sick person before medical help arrives
  • C. Treating a victim for shock
  • D. Assessing a victim's vital signs
Answer: B — The first help given to an accident victim or sick person before medical help arrives
First aid is the immediate care given to an injured or ill person to preserve life, prevent the condition worsening and promote recovery until qualified medical help is available.

6. Fainting can be described as ____.

  • A. A response to fear
  • B. A brief loss of consciousness
  • C. An unexpected collapse with injury
  • D. A sign of flu
Answer: B — A brief loss of consciousness
Fainting (syncope) is a brief loss of consciousness caused by a temporary reduction of blood flow to the brain. The casualty usually recovers quickly when laid flat with the legs raised.

7. Signs of head and spine injuries are ____.

  • A. Blood or other fluids in the ears or nose
  • B. Unusual bumps or depressions on the head or over the spine
  • C. Seizures, severe headache or slurred speech
  • D. All of the above
Answer: D — All of the above
Head and spinal injuries may show fluid or blood from the ears or nose, deformities of the skull or spine, seizures, headache, slurred speech or altered consciousness. Any of these require keeping the head and neck still.

8. To encourage people to help others in emergencies, many countries have laws that protect a rescuer acting in good faith from being sued. This is called ____.

  • A. The Good-Will Law
  • B. The First Aid No-Fault Law
  • C. The Good Samaritan Law
  • D. There is no such law
Answer: C — The Good Samaritan Law
Good Samaritan laws protect people who give reasonable emergency assistance in good faith from legal liability, provided they act within their training. India also has Good Samaritan guidelines protecting those who help accident victims.

9. Which of the following heat-related conditions is the most serious?

  • A. Heat stroke
  • B. Heat exhaustion
  • C. Heat cramps
  • D. Heat rash
Answer: A — Heat stroke
Heat stroke is a life-threatening emergency in which the body's temperature control fails and core temperature rises above about 40 °C, damaging the brain and organs. It needs immediate cooling and medical help.

10. Signs of heat stroke include ____.

  • A. Very high body temperature
  • B. Hot, red, dry skin
  • C. Rapid pulse and shallow breathing
  • D. All of the above
Answer: D — All of the above
In heat stroke the body's cooling fails: temperature becomes very high, the skin is hot, red and often dry, the pulse is rapid and breathing shallow, and the casualty may be confused or unconscious.

11. An enclosed space can be entered ____.

  • A. When it looks clear
  • B. Whenever you have work to do inside
  • C. Only after the atmosphere has been tested and found safe and an entry permit issued
  • D. At your own choice
Answer: C — Only after the atmosphere has been tested and found safe and an entry permit issued
Under IMO Resolution A.1050(27) and SOLAS XI-1/7, entry into an enclosed space requires ventilation, testing of the atmosphere for oxygen, flammable and toxic gases with calibrated instruments, and an entry permit before anyone goes in.

12. Burns covering more than 15 percent of the body require ____.

  • A. Only the first aider's advice
  • B. A doctor's advice
  • C. Self-medication
  • D. Nothing, as they will cure automatically
Answer: B — A doctor's advice
Large burns cause major fluid loss and can lead to shock and infection. Burns over about 15 percent of body surface in adults are serious and need medical treatment and evacuation; first aid alone is not enough.

13. You may suspect that a person has been poisoned if he ____.

  • A. Has nausea, vomiting or diarrhoea
  • B. Has chest or abdominal pain or breathing difficulty
  • C. Has burns around the lips, tongue or on the skin
  • D. All of the above
Answer: D — All of the above
Poisoning can cause gastrointestinal upset, pain, breathing difficulty, and burns around the mouth from corrosive substances. Look also for containers, odours or chemicals nearby that point to the cause.

14. A first-degree burn ____.

  • A. Involves only the top layer of skin
  • B. Is red and blistered
  • C. Destroys all layers of skin
  • D. Is the most serious type of burn
Answer: A — Involves only the top layer of skin
A first-degree (superficial) burn affects only the epidermis, causing redness, pain and minor swelling without blisters. Blistering indicates a second-degree burn and destruction of all layers a third-degree burn.

15. Which is NOT a symptom of shock?

  • A. Strong thirst, nausea or vomiting
  • B. Rapid breathing or rapid pulse
  • C. Restlessness or irritability
  • D. Chest or abdominal pain
Answer: D — Chest or abdominal pain
Shock typically shows thirst, nausea, rapid breathing, rapid weak pulse, pale cool skin and restlessness or irritability. Chest or abdominal pain is a sign of the underlying injury or illness, not a symptom of shock itself.

16. Wounds that would require stitches are those that are ____.

  • A. Over an inch long or gaping
  • B. Bleeding from an artery or bleeding uncontrollably
  • C. Human or animal bites
  • D. All of the above
Answer: D — All of the above
Wounds that are long or gaping, bleed heavily or from an artery, or result from bites need medical attention and usually stitches or professional cleaning to control bleeding, close the wound and prevent infection.

17. Which symptoms would indicate internal bleeding?

  • A. A rapid, weak pulse
  • B. Skin that feels cool or moist, or looks pale or bluish
  • C. Excessive thirst
  • D. All of the above
Answer: D — All of the above
Internal bleeding reduces circulating blood volume and leads to shock, giving a rapid weak pulse, pale or bluish cool moist skin and excessive thirst. Such casualties need urgent medical care.

18. A crew member has been hit in the mouth and a tooth has been knocked out. You should ____.

  • A. Control the bleeding by having him bite on a rolled sterile dressing in the tooth socket
  • B. Save the tooth by placing it in milk or water
  • C. Wrap the tooth in a dry tissue and give it to him to take to the dentist
  • D. Both control the bleeding with a rolled dressing and save the tooth in milk or water
Answer: D — Both control the bleeding with a rolled dressing and save the tooth in milk or water
First control the bleeding by having the casualty bite on a rolled dressing in the socket, and preserve the tooth by keeping it moist in milk or water. The tooth should not be dried, and a dentist should be seen quickly.

19. When caring for a victim with a nosebleed, you would NOT ____.

  • A. Apply an ice pack to the bridge of the nose
  • B. Apply pressure to the upper lip just beneath the nose
  • C. Have the victim sit with the head tilted slightly forward while pinching the nostrils together
  • D. Have the victim sit with the head tilted slightly backward while pinching the nostrils together
Answer: D — Have the victim sit with the head tilted slightly backward while pinching the nostrils together
Tilting the head back makes blood run down the throat, where it may be swallowed causing vomiting or block the airway. The casualty should lean forward and pinch the soft part of the nose.

20. Elastic bandages are used to ____.

  • A. Control severe bleeding
  • B. Control swelling and support injuries such as sprains or strains
  • C. Allow circulation to a severed limb
  • D. Replace a splint
Answer: B — Control swelling and support injuries such as sprains or strains
Elastic (roller) bandages give gentle compression and support to joints and muscles, reducing swelling in sprains and strains. They must not be applied so tightly that circulation is cut off.

21. Bandages are used ____.

  • A. By applying them directly to a wound to soak up blood
  • B. To hold dressings in place, apply pressure and help control bleeding
  • C. To ease pain only
  • D. For small cuts only
Answer: B — To hold dressings in place, apply pressure and help control bleeding
A dressing is placed directly on the wound; the bandage holds the dressing in place, applies pressure to help control bleeding, and supports or immobilises the injured part.

22. Which is NOT a symptom of a heart attack?

  • A. Chest pain
  • B. Red, hot, dry skin
  • C. Pale or bluish skin colour
  • D. Profuse sweating
Answer: B — Red, hot, dry skin
A heart attack typically causes crushing chest pain, pale or bluish skin, profuse sweating, breathlessness and nausea. Red, hot, dry skin is a sign of heat stroke, not a heart attack.

23. A person who is unconscious and not breathing but has a weak pulse needs ____.

  • A. CPR with chest compressions
  • B. The Heimlich manoeuvre
  • C. Rescue breathing
  • D. Back blows and chest thrusts
Answer: C — Rescue breathing
If the casualty has a pulse but is not breathing, the heart is still beating, so rescue breathing is given to supply oxygen while the pulse is checked regularly. Compressions start only if the pulse is lost.

24. Breathing emergencies may be caused by ____.

  • A. Asthma
  • B. Hyperventilation
  • C. An allergic reaction
  • D. All of the above
Answer: D — All of the above
Breathing emergencies arise from many causes, including asthma attacks narrowing the airways, hyperventilation from anxiety, and allergic reactions causing airway swelling. All need prompt recognition and first aid.

25. Most injuries are due to situations that ____.

  • A. You have no control over and could not have been prevented
  • B. You have some control over and could have been prevented
  • C. Involve five or more people
  • D. Involve water sports
Answer: B — You have some control over and could have been prevented
Most accidents and injuries result from preventable causes such as unsafe acts, poor housekeeping or ignoring procedures. Good safety practice, risk assessment and the correct use of PPE prevent most injuries on board.

26. Dressings and bandages are used to ____.

  • A. Reduce the victim's pain
  • B. Reduce internal bleeding
  • C. Help control bleeding and prevent infection
  • D. Make it easier to take the victim to hospital
Answer: C — Help control bleeding and prevent infection
A sterile dressing protects the wound from contamination and helps blood clot, while a bandage holds it in place with pressure. Together they help control external bleeding and reduce the risk of infection.

27. You have tried to control bleeding from a forearm wound with direct pressure and elevation, but it does not stop. Where would you apply pressure to slow the flow of blood?

  • A. On the outside of the arm, midway between the shoulder and the elbow
  • B. On the inside of the elbow
  • C. On the inside of the arm, between the shoulder and the elbow
  • D. Any of the above will slow the flow of blood
Answer: C — On the inside of the arm, between the shoulder and the elbow
The brachial artery runs along the inside of the upper arm between the shoulder and elbow. Pressing it against the bone at this pressure point reduces blood flow to the forearm when direct pressure alone fails.

28. Which should be part of your care for a severely bleeding open wound?

  • A. Allow the wound to bleed in order to minimise infection
  • B. Apply direct pressure and elevate the injured area, if no broken bones
  • C. Use a tourniquet first to stop all blood flow
  • D. Wash the wound under running water until bleeding stops
Answer: B — Apply direct pressure and elevate the injured area, if no broken bones
Direct pressure on the wound, with elevation of the limb if there is no fracture, is the first and most effective way to control severe bleeding. A tourniquet is used only for life-threatening limb bleeding that pressure cannot control.

29. A stroke is an injury to the ____.

  • A. Leg
  • B. Chest
  • C. Brain
  • D. Stomach
Answer: C — Brain
A stroke occurs when the blood supply to part of the brain is blocked or a blood vessel in the brain bursts. Brain cells are deprived of oxygen, causing weakness, speech problems or loss of consciousness.

30. Severe shock requires ____.

  • A. Only the first aider's advice
  • B. A doctor's advice
  • C. Self-medication
  • D. Nothing, as it will cure automatically
Answer: B — A doctor's advice
Severe shock is life-threatening because the vital organs are not receiving enough blood. After first aid such as laying the casualty down and keeping them warm, urgent medical treatment is needed, via radio medical advice at sea.
