Answer Key

EFA exit exam questions and answers — Set 38 — Elementary First Aid

Set 38 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 38 — 30 EFA exit exam questions with answers

1. When a stretcher casualty is carried up a stairway or ladder, the casualty's head should normally be:

  • A. At the same level as the feet
  • B. Uppermost
  • C. Lowermost
  • D. Turned to one side and lowered
Answer: B — Uppermost
A stretcher is generally carried feet first on level ground, but on stairs or slopes the head is kept uphill so the casualty is not tipped head-down, unless a specific condition requires otherwise.

2. When a team carries a casualty on a stretcher, commands are normally given by:

  • A. The casualty himself
  • B. The bearer at the feet
  • C. Any bearer who wishes
  • D. The bearer at the casualty's head, who can watch the casualty
Answer: D — The bearer at the casualty's head, who can watch the casualty
One person controls the lift so everyone moves together. The bearer at the head can observe the casualty's face and airway and usually gives commands such as prepare to lift and lift.

3. Filter-type (canister) respirators must not be used to rescue a casualty from an enclosed space because they:

  • A. Cannot be worn with gloves
  • B. Supply too much oxygen
  • C. Are too heavy to wear
  • D. Do not supply oxygen and give no protection in an oxygen-deficient atmosphere
Answer: D — Do not supply oxygen and give no protection in an oxygen-deficient atmosphere
A filter respirator only removes certain contaminants from the air breathed. It cannot make up for a lack of oxygen, so rescuers must wear self-contained or airline breathing apparatus.

4. Under SOLAS, enclosed space entry and rescue drills must be carried out at least:

  • A. Once a year
  • B. Once every two months
  • C. Only when the ship is in dry dock
  • D. Once a week
Answer: B — Once every two months
SOLAS regulation III/19.3.6, in force since 2015, requires enclosed space entry and rescue drills to be held at least once every two months so crew can rescue casualties without becoming casualties themselves.

5. A large proportion of deaths in enclosed spaces on ships involve:

  • A. Would-be rescuers who enter without breathing apparatus
  • B. Persons wearing breathing apparatus correctly
  • C. Officers on watch on the bridge
  • D. Persons standing by at the entrance
Answer: A — Would-be rescuers who enter without breathing apparatus
Casualty records show that many enclosed space deaths are of crew who rush in to help a collapsed shipmate without protection. The alarm must be raised and only properly equipped rescuers should enter.

6. A hypothermic survivor is recovered from the water. He should, if possible, be lifted:

  • A. Head first
  • B. Vertically by a single strop under the arms
  • C. By the arms
  • D. In a horizontal position
Answer: D — In a horizontal position
A vertical lift of a cold casualty can cause a sudden drop in blood pressure and collapse because the water pressure that supported circulation is removed; lifting horizontally reduces this risk.

7. During a log-roll of a casualty with a suspected spinal injury, the timing of the roll is controlled by:

  • A. The rescuer holding the stretcher
  • B. The rescuer at the feet
  • C. The rescuer holding the casualty's head
  • D. The casualty
Answer: C — The rescuer holding the casualty's head
The person supporting the head keeps the head and neck in line with the trunk and gives the commands, so the whole body turns as one unit without twisting the spine.

8. An improvised stretcher can be made from:

  • A. A single plank tied to a rope
  • B. A folded hammock without poles
  • C. Two strong poles passed through the sleeves of two or three buttoned-up jackets
  • D. A lifebuoy and line
Answer: C — Two strong poles passed through the sleeves of two or three buttoned-up jackets
Jackets with sleeves turned inside out and poles passed through the sleeves form a usable stretcher bed. Blankets folded around two poles can also be used.

9. Before an improvised stretcher is used to carry a casualty, it should be:

  • A. Used without testing to save time
  • B. Soaked in water
  • C. Tested by lifting an uninjured person of similar weight
  • D. Painted for visibility
Answer: C — Tested by lifting an uninjured person of similar weight
An improvised stretcher may fail under load, which could worsen the casualty's injuries. Testing it with an uninjured person first confirms that it is strong enough.

10. When a casualty is evacuated ashore or to another vessel, which of the following should go with him?

  • A. Nothing, as the hospital will examine him
  • B. A written record of injuries, observations, treatment and drugs given, with times
  • C. His personal effects but no medical information
  • D. Only his passport
Answer: B — A written record of injuries, observations, treatment and drugs given, with times
A written record lets the receiving doctor know what happened, how the casualty's condition has changed, and what treatment and medication were given and when.

11. The cradle carry by a single rescuer is suitable for:

  • A. Unconscious heavy adults
  • B. Children and light adults
  • C. Heavy adults with leg injuries
  • D. Casualties with suspected spinal injury
Answer: B — Children and light adults
In the cradle carry the rescuer lifts the casualty in both arms, one under the back and one under the knees. It is only practical for children and light adults over short distances.

12. A hypothermic casualty should be handled gently during rescue and transport because rough handling may:

  • A. Cause heat stroke
  • B. Cause ventricular fibrillation (cardiac arrest)
  • C. Cause frostbite
  • D. Raise the body temperature too fast
Answer: B — Cause ventricular fibrillation (cardiac arrest)
A very cold heart is irritable, and jolting or rough handling can trigger ventricular fibrillation. The casualty should be kept horizontal, insulated against further heat loss and moved gently.

13. When a rescue strop (horse collar) is lowered from a helicopter to lift a survivor, it should be placed:

  • A. Under the knees
  • B. Around the waist only
  • C. Around the back and under the armpits, with arms kept down at the sides
  • D. Around the neck
Answer: C — Around the back and under the armpits, with arms kept down at the sides
The strop goes around the back and under both armpits, with the toggle pulled down, and the survivor keeps the arms down; raising the arms could let him slip out.

14. Before a casualty on a stretcher is moved through narrow passages or up ladders on a rolling ship, he should be:

  • A. Sat upright on the stretcher
  • B. Allowed to hold onto the stretcher himself
  • C. Securely strapped to the stretcher
  • D. Covered but not secured
Answer: C — Securely strapped to the stretcher
A rolling ship and steep ladders can tip the stretcher. Securing the casualty with straps prevents him falling or sliding, which could cause further injury.

15. Which of the following should be done before moving a casualty, unless there is immediate danger?

  • A. Give him painkillers and food
  • B. Remove all his clothing
  • C. Treat life-threatening conditions and immobilise fractures
  • D. Wash his face with cold water
Answer: C — Treat life-threatening conditions and immobilise fractures
Unless the scene is dangerous, airway, breathing and severe bleeding are dealt with and fractures immobilised first, so that moving the casualty does not make his injuries worse.

16. A rescuer entering an enclosed space to rescue a collapsed crew member should be wearing:

  • A. A canister gas mask
  • B. Self-contained breathing apparatus and a lifeline, with an attendant at the entrance
  • C. A dust mask
  • D. Overalls only, to save time
Answer: B — Self-contained breathing apparatus and a lifeline, with an attendant at the entrance
The atmosphere that overcame the casualty will overcome the rescuer. Rescuers must wear breathing apparatus and a lifeline, and someone must remain at the entrance to keep communications and raise the alarm.

17. A conscious casualty who can walk with a little help should normally be:

  • A. Carried by the fireman's lift
  • B. Strapped onto a Neil Robertson stretcher
  • C. Dragged by the ankles
  • D. Assisted to walk using the human crutch method
Answer: D — Assisted to walk using the human crutch method
If a casualty can walk with support and his injuries allow it, the human crutch method is the simplest and least distressing way to move him a short distance.

18. A single rescuer must urgently pull an unconscious casualty clear of smoke. A suitable method is to:

  • A. Roll him along the deck
  • B. Drag him by the ankles over steps
  • C. Drag him by the clothing at the shoulders, with the head supported on the rescuer's forearms
  • D. Lift him onto the shoulder by the arms
Answer: C — Drag him by the clothing at the shoulders, with the head supported on the rescuer's forearms
The clothes or shoulder drag moves the casualty along his body axis while the rescuer's forearms support and protect the head, and it can be done by one rescuer staying low under smoke.

19. Shock caused by a spinal cord injury, in which the blood vessels dilate and blood pressure falls, is called:

  • A. Neurogenic shock
  • B. Hypovolaemic shock
  • C. Septic shock
  • D. Anaphylactic shock
Answer: A — Neurogenic shock
Damage to the spinal cord can interrupt the nerves that keep blood vessels toned. The vessels widen, blood pools and pressure falls, which is known as neurogenic shock.

20. Shock that results from the heart failing to pump effectively, for example after a heart attack, is called:

  • A. Septic shock
  • B. Hypovolaemic shock
  • C. Cardiogenic shock
  • D. Neurogenic shock
Answer: C — Cardiogenic shock
In cardiogenic shock the volume of blood is normal but the damaged heart cannot pump enough of it around the body, so the tissues do not receive adequate oxygen.

21. Which of the following is a late and serious sign of shock?

  • A. Pale skin
  • B. Sweating
  • C. Restlessness progressing to drowsiness and loss of consciousness
  • D. Slightly raised pulse
Answer: C — Restlessness progressing to drowsiness and loss of consciousness
Pale, sweaty skin and a rising pulse appear early. As shock worsens the brain is starved of oxygen, and the casualty becomes restless, confused, drowsy and finally unconscious, which may precede cardiac arrest.

22. When the nail bed of a casualty in shock is pressed and released, the colour takes longer than about two seconds to return. This indicates:

  • A. High blood pressure
  • B. Normal circulation
  • C. A fracture of the finger
  • D. Poor circulation to the extremities
Answer: D — Poor circulation to the extremities
Capillary refill normally returns within about two seconds. A slower return shows that the blood supply to the skin and extremities has been reduced, as happens in shock.

23. A casualty in shock complains of thirst. You should:

  • A. Give him a hot sweet drink
  • B. Give him a small amount of alcohol
  • C. Moisten his lips with water but give nothing to drink
  • D. Give him plenty of water
Answer: C — Moisten his lips with water but give nothing to drink
Anything taken by mouth may cause vomiting and could delay an anaesthetic if surgery is needed. Moistening the lips relieves the discomfort of thirst without these risks.

24. Hot water bottles or other direct heat should not be used on a casualty in shock because:

  • A. They draw blood to the skin and away from the vital organs
  • B. They will cause the casualty to fall asleep
  • C. They are too heavy for the casualty
  • D. They raise blood sugar
Answer: A — They draw blood to the skin and away from the vital organs
The body reduces blood flow to the skin in shock to protect the vital organs. Direct heat reverses this and diverts blood away from where it is most needed; a blanket to prevent heat loss is enough.

25. An adrenaline auto-injector for a casualty in anaphylactic shock should be given into the:

  • A. Back of the hand
  • B. Chest wall
  • C. Outer side of the thigh
  • D. Abdomen
Answer: C — Outer side of the thigh
Auto-injectors are designed to be pressed firmly against the outer mid-thigh, and can be used through clothing, giving the adrenaline into the large thigh muscle where it is absorbed quickly.

26. While waiting for medical help, the pulse, breathing and level of response of a casualty in shock should be:

  • A. Checked only if he complains
  • B. Left alone so as not to disturb him
  • C. Checked and recorded at regular intervals, such as every 10 minutes
  • D. Checked once only
Answer: C — Checked and recorded at regular intervals, such as every 10 minutes
Shock can worsen quickly. Regular recorded observations show whether the casualty is improving or deteriorating and give valuable information for radio medical advice or the receiving doctor.

27. A casualty in shock begins yawning and gasping for air. This most likely indicates:

  • A. The brain is short of oxygen and the condition is worsening
  • B. The casualty is simply tired
  • C. The casualty is recovering
  • D. The casualty has eaten too much
Answer: A — The brain is short of oxygen and the condition is worsening
Yawning, sighing and gasping, sometimes called air hunger, are signs that the brain is not getting enough oxygen and that shock is getting worse. Urgent medical advice is needed.

28. Which of the following best helps a casualty in shock?

  • A. Giving him a stimulant such as coffee
  • B. Giving him a large meal
  • C. Encouraging him to walk to keep the circulation going
  • D. Treating the cause, laying him down, raising the legs if possible, keeping him warm and reassured
Answer: D — Treating the cause, laying him down, raising the legs if possible, keeping him warm and reassured
Basic shock management combines treating the cause such as bleeding, laying the casualty down with legs raised if injuries allow, preventing heat loss, reassurance and getting medical help.

29. In shock caused by severe burns, the fall in circulating volume is mainly due to:

  • A. Spinal cord damage
  • B. Failure of the heart muscle
  • C. Loss of plasma from the burned area
  • D. Infection of the blood
Answer: C — Loss of plasma from the burned area
Burns damage blood vessels so that large amounts of plasma leak into the tissues and out of the burn, reducing the volume of circulating blood and causing hypovolaemic shock.

30. In a casualty developing shock, a fall in blood pressure is usually:

  • A. A sign of recovery
  • B. A late sign, appearing after the pulse has already become rapid
  • C. Never seen
  • D. The first sign to appear
Answer: B — A late sign, appearing after the pulse has already become rapid
The body compensates for falling blood volume by speeding up the heart and narrowing vessels, so blood pressure is maintained at first. A fall in blood pressure indicates that compensation is failing.
