Answer Key

EFA exit exam questions and answers — Set 40 — Elementary First Aid

Set 40 of the Elementary First Aid (EFA) exit exam bank — 15 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 40 — 15 EFA exit exam questions with answers

1. How many vertebrae are there in the neck (cervical spine)?

  • A. 5
  • B. 7
  • C. 12
  • D. 33
Answer: B — 7
The spine has 7 cervical, 12 thoracic and 5 lumbar vertebrae, followed by the sacrum and coccyx. The cervical vertebrae support the head and protect the spinal cord in the neck.

2. The organs that filter waste from the blood and produce urine are the:

  • A. Kidneys
  • B. Pancreas
  • C. Spleen
  • D. Lungs
Answer: A — Kidneys
The two kidneys filter the blood, remove waste and excess water as urine, and help control the body's fluid and salt balance. Urine passes down the ureters to the bladder.

3. The radial pulse is felt:

  • A. At the side of the neck
  • B. Behind the knee
  • C. In the groin
  • D. At the wrist on the thumb side
Answer: D — At the wrist on the thumb side
The radial artery runs on the thumb side of the front of the wrist and is the usual place to take the pulse of a conscious adult.

4. Bones are joined to other bones at a joint by:

  • A. Cartilage only
  • B. Ligaments
  • C. Nerves
  • D. Tendons
Answer: B — Ligaments
Ligaments are strong fibrous bands that link bone to bone and stabilise joints; tendons attach muscles to bones. A sprain is an injury to a ligament.

5. The brain and spinal cord are surrounded and cushioned by:

  • A. Bile
  • B. Synovial fluid
  • C. Lymph
  • D. Cerebrospinal fluid
Answer: D — Cerebrospinal fluid
Cerebrospinal fluid circulates around the brain and spinal cord, protecting them from shocks. Leakage of this fluid from the nose or ear after a head injury may indicate a skull fracture.

6. The hip and shoulder are examples of which type of joint?

  • A. Fixed
  • B. Hinge
  • C. Ball and socket
  • D. Pivot
Answer: C — Ball and socket
In a ball and socket joint the rounded head of one bone fits into a cup in another, allowing movement in many directions. The elbow and knee are hinge joints.

7. The organ that produces bile, stores glycogen and removes many toxins from the blood is the:

  • A. Stomach
  • B. Spleen
  • C. Kidney
  • D. Liver
Answer: D — Liver
The liver produces bile for digesting fats, stores glycogen as an energy reserve and breaks down many drugs and toxins. It is also very vascular and bleeds heavily if injured.

8. Using the rule of nines, one entire leg of an adult represents about what percentage of the body surface?

  • A. 27%
  • B. 18%
  • C. 36%
  • D. 9%
Answer: B — 18%
The rule of nines gives 9% for the head and neck, 9% for each arm, 18% for the front of the trunk, 18% for the back and 18% for each leg, with 1% for the genital area.

9. After cooling, a burn may be covered with:

  • A. An adhesive plaster stuck over the burn
  • B. Kitchen cling film or a clean, non-fluffy dressing
  • C. Cotton wool
  • D. Butter or cooking oil
Answer: B — Kitchen cling film or a clean, non-fluffy dressing
Cling film or a sterile non-fluffy dressing protects the burn from infection without sticking to it. Cotton wool sticks to the wound and fats or creams hold in heat and increase infection risk.

10. Which of the following should NOT be applied to a burn?

  • A. A sterile non-fluffy dressing
  • B. Cool running water
  • C. Cling film laid loosely over the burn
  • D. Ointments, creams, butter or adhesive dressings
Answer: D — Ointments, creams, butter or adhesive dressings
Ointments and fats retain heat and must be cleaned off later by medical staff, while adhesive dressings damage the skin when removed. Cool water and a non-adherent covering are the correct first aid.

11. Rings, watches and tight clothing near a burned area should be:

  • A. Taped tightly in position
  • B. Removed gently before the area starts to swell
  • C. Removed only after the casualty reaches hospital
  • D. Left in place to protect the skin
Answer: B — Removed gently before the area starts to swell
Burned tissue swells rapidly, and rings or tight items can then act like a tourniquet and cut off circulation, so they should be removed early unless they are stuck to the burn.

12. Which of the following suggests a burn to the airway?

  • A. A blister on one finger
  • B. Sunburn on the back
  • C. Redness of the forearm only
  • D. Soot around the nose and mouth, singed nasal hair and a hoarse voice
Answer: D — Soot around the nose and mouth, singed nasal hair and a hoarse voice
Burns or soot around the mouth and nose, singed hairs, hoarseness and difficulty breathing indicate that hot gases have been inhaled. Airway swelling can develop rapidly and urgent medical help is needed.

13. With a high-voltage electrical accident, bystanders should keep a distance of at least about 18 metres until the supply is cut off because:

  • A. Rubber boots give full protection
  • B. High voltage can arc across a distance and electrify the surrounding area
  • C. Dry wood conducts high voltage safely
  • D. The casualty will recover by himself
Answer: B — High voltage can arc across a distance and electrify the surrounding area
High-voltage electricity can jump considerable distances and electrify the ground nearby. No one should approach the casualty until the supply has been isolated by the responsible person.

14. The most immediate life-threatening effect of an electric shock passing through the chest is:

  • A. A small entry burn on the hand
  • B. Cardiac arrest from ventricular fibrillation
  • C. A sprained wrist
  • D. Frostbite
Answer: B — Cardiac arrest from ventricular fibrillation
Current crossing the heart can disrupt its rhythm, causing ventricular fibrillation and cardiac arrest. Once the casualty is safe to touch, check breathing and start CPR and use an AED if he is not breathing normally.

15. A crew member is scalded by steam in the engine room. After making the area safe, the first aid priority is to:

  • A. Apply ice directly to the skin
  • B. Cool the scalded area with cool running water
  • C. Cover it with oil
  • D. Burst the blisters
Answer: B — Cool the scalded area with cool running water
Scalds are treated like any other heat burn. Cooling with cool running water reduces pain, swelling and tissue damage; ice can damage tissue further and blisters should be left intact.
