    Where are the body's blood cells produced?

    • Bone marrow

    • Epiphyseal plate

    • Cardiac tissue

    • Pelvic girdle

    • Cranium

    Correct Answer
    A. Bone marrow
    Explanation
    Blood cells are produced in the bone marrow. The bone marrow is a soft, spongy tissue found inside the bones. It contains stem cells that can differentiate into various types of blood cells, including red blood cells, white blood cells, and platelets. These blood cells are essential for carrying oxygen, fighting infections, and clotting blood. The bone marrow plays a crucial role in the production and maintenance of the body's blood cells.

    A pelvic injury is considered a minor one. True or false?

    • True

    • False

    Correct Answer
    A. False
    Explanation
    A pelvic injury is not considered a minor one. Pelvic injuries can be serious and potentially life-threatening, as they can involve fractures, organ damage, and internal bleeding. These injuries often require immediate medical attention and may require surgery or other interventions for proper treatment. Therefore, the statement that a pelvic injury is considered a minor one is false.

    The scapula would be an example of what type of bone?

    • Long

    • Short

    • Flat

    • Irregular

    Correct Answer
    A. Flat
    Explanation
    The scapula, also known as the shoulder blade, is a large, flat bone located in the upper back. It serves as a point of attachment for various muscles and ligaments, allowing for movement and stability of the shoulder joint. Flat bones are typically thin, flat, and curved, providing protection to internal organs and serving as sites for muscle attachment. The scapula fits this description, making it an example of a flat bone.

    • 12

    • 18

    • 5

    • 7

    • 4

    Correct Answer
    A. 12
    Explanation
    There are 12 thoracic vertebrae in the human body. The thoracic vertebrae are located in the middle region of the spine, between the cervical vertebrae in the neck and the lumbar vertebrae in the lower back. These vertebrae provide support and protection to the rib cage and help to maintain the upright posture of the body.

    What is the main reason the hyoid bone so unique?

    • It is the smallest bone in the human body.

    • There is no hyoid bone. This is a trick question.

    • It is the only bone in the human body that does not connect to another bone.

    • It disappears after the age of 40.

    • Without it you wouldn't be able to hear.

    Correct Answer
    A. It is the only bone in the human body that does not connect to another bone.
    Explanation
    The hyoid bone is unique because it is the only bone in the human body that does not connect to another bone. Other bones in the body are connected to each other, either directly or indirectly, but the hyoid bone floats freely in the neck and is held in place by muscles and ligaments. Its position and structure allow it to support the tongue and play a crucial role in swallowing, speaking, and breathing.

  • 12. 

    What is the best type of splinting for an upper arm injury?

    • Traction splinting

    • Sling and swathe

    • Pneumatic splint

    Correct Answer
    A. Sling and swathe
    Explanation
    The best type of splinting for an upper arm injury is a sling and swathe. This type of splint provides support and immobilization to the injured arm by suspending it in a sling and wrapping it with a swathe. This helps to reduce pain, prevent further injury, and promote healing. Traction splinting is typically used for fractures of the lower extremities, while a pneumatic splint involves the use of air pressure to stabilize and immobilize the injured area.

  • 13. 

    Why is this so? (refer to question #5)

    • Kids are extremely active making this type of fracture more common.

    • Bones of children are extremely rigid and brittle so tend to break quite easily.

    • Bones in children are more flexible and have the ability to bend more before breaking.

    • This type of fracture occurs because children don't have any bones yet, they just have cartilege.

    Correct Answer
    A. Bones in children are more flexible and have the ability to bend more before breaking.
    Explanation
    Children's bones are more flexible and have the ability to bend more before breaking. This is why this type of fracture is more common in kids.

    What is another name for the elbow joint?

    • Calcaneus

    • Olecranon

    • Humerus

    • Greater trochanter

    Correct Answer
    A. Olecranon
    Explanation
    The olecranon is a bony prominence located at the upper end of the ulna bone in the forearm. It forms the point of the elbow joint and is commonly referred to as the elbow. Therefore, the correct answer for another name for the elbow joint is olecranon.

    What is the most common type of fracture seen in children?

    • Comminuted

    • Transverse

    • Linear

    • Spiral

    • Greenstick

    Correct Answer
    A. Greenstick
    Explanation
    Greenstick fractures are the most common type of fracture seen in children. These fractures occur when the bone bends and cracks, but does not completely break. This is because children's bones are more flexible and have a higher proportion of collagen, making them more likely to bend rather than break. Greenstick fractures are typically seen in the long bones of the forearm and lower leg.

    Rate this question:

  • 16. 

    Where would you most likely find the acetabulum?

    • Skull

    • Wrist

    • Tailbone

    • Hip

    • Ankle

    Correct Answer
    A. Hip
    Explanation
    The acetabulum is a part of the hip bone. It is a socket-shaped structure that forms the hip joint by connecting with the head of the femur (thigh bone). Therefore, it is most likely to be found in the hip region.

    Rate this question:

  • 17. 

    At a one car MVC where the driver hit a light pole going at an estimated speed of 50 mph, what type of hip dislocation would you likely see?

    • Posterior dislocation

    • Anterior dislocation

    Correct Answer
    A. Posterior dislocation
    Explanation
    In a one car motor vehicle collision where the driver hits a light pole at a high speed, the force of the impact is likely to cause a posterior dislocation of the hip. This means that the hip joint would be pushed out of its normal position towards the back of the body. The strong force exerted on the hip joint in this scenario is more likely to result in a posterior dislocation rather than an anterior dislocation.

    Rate this question:

  • 18. 

    Why is an elbow injury considered a serious one?

    • There are many nerves and blood vessels in this area.

    • An extraordinary amount of blood can be lost if this area is injured.

    • If injured badly enough, it cannot be fixed.

    • It is not considered a serious injury. This is a bogus question.

    Correct Answer
    A. There are many nerves and blood vessels in this area.
    Explanation
    An elbow injury is considered a serious one because there are many nerves and blood vessels in this area. This means that any damage to the elbow can potentially result in significant loss of blood and nerve damage. Additionally, if the injury is severe enough, it may not be possible to fully repair or restore the function of the elbow.

    Rate this question:

  • 19. 

    Where is the humerus most often fractured?

    • At the bottom near the elbow

    • In the growth areas

    • Near the shoulder or in the middle

    • Straight down the middle (vertically) of the bone

    Correct Answer
    A. Near the shoulder or in the middle
    Explanation
    The humerus, which is the bone in the upper arm, is most often fractured near the shoulder or in the middle. This is because these areas of the bone are more susceptible to forces and impacts that can cause fractures. Fractures near the shoulder can occur due to falls or direct blows to the upper arm, while fractures in the middle can result from direct trauma or excessive stress on the bone. Fractures at the bottom near the elbow or straight down the middle of the bone are less common compared to fractures near the shoulder or in the middle.

    A wrist injury is always easy because the bones are so close to the surface. True or false?

    • True

    • Wrong-o!

    Correct Answer
    A. Wrong-o!
  • 21. 

    If a child is not walking on an extremity, what should you suspect?

    • Fracture (s)

    • Nothing, kids are quirky

    • Severe bruising only, kids' bones don't normally break

    • Dislocation (s)

    Correct Answer
    A. Fracture (s)
    Explanation
    If a child is not walking on an extremity, it suggests that there may be a fracture(s) in that extremity. Fractures can cause pain and limit the child's ability to bear weight on the affected limb, therefore resulting in difficulty or refusal to walk. This is a common sign of a fracture in children.

    What does this vertebra do?

    • It does the same thing the rest of the vertebrae do

    • Controls movement of the spine

    • Houses all of the cranial nerves

    • Support the weight of the skull

    Correct Answer
    A. Support the weight of the skull
    Explanation
    This vertebra supports the weight of the skull. The vertebrae in the spine are responsible for providing support and stability to the body. In this case, this particular vertebra specifically supports the weight of the skull, which is an important function to maintain proper alignment and balance of the head.

    Rate this question:

  • 23. 

    What would this condition look like?

    • Hip is slightly bent with leg turned outward and away from midline

    • Hip is fixed with leg turned inward towards the middle of the body

    Correct Answer
    A. Hip is fixed with leg turned inward towards the middle of the body
    Explanation
    This condition describes a fixed hip with the leg turned inward towards the middle of the body. This means that the hip joint cannot move freely and the leg is rotated inward, pointing towards the midline of the body. This could be due to a hip deformity or injury that restricts the movement of the hip joint and causes the leg to be positioned inwards.

    How many floating ribs are there?

    • 12

    • 0

    • 2

    • 4

    • 6

    Correct Answer
    A. 4
    Explanation
    There are four floating ribs in the human body. Floating ribs are the last two pairs of ribs in the ribcage, and unlike the other ribs, they do not connect to the sternum or any other ribs. They are attached only to the vertebrae in the back, providing support and protection to the lower organs.

    Rate this question:

    Which vertebra is most likely to have been damaged if the patient's diaphragm is no longer in working condition?

    • T 9

    • L 1

    • C 1

    • T 5

    • C 3

    Correct Answer
    A. C 3
    Explanation
    The diaphragm is innervated by the phrenic nerve, which originates from the C3, C4, and C5 nerve roots. Therefore, if the diaphragm is no longer in working condition, it is most likely that there has been damage to the C3 vertebra.
