L.P. Book Medical / Lesson # 6 Fractures

The correct answer is "All of the above" because the mechanism of injuries can occur due to direct force, indirect force, or twisting force. Direct force refers to injuries caused by a direct impact or blow to the body. Indirect force refers to injuries caused by a force transmitted through the body, such as a fall on an outstretched hand causing a wrist fracture. Twisting force refers to injuries caused by a twisting or rotating motion, such as a sprained ankle from twisting the foot. Therefore, all three types of forces can lead to different types of injuries.

The components of the Skeletal System include the Skull, Spinal Column, and Thorax. These three parts make up the main structures of the skeletal system. The skull protects the brain and forms the structure of the face, while the spinal column supports the body and protects the spinal cord. The thorax consists of the ribs and sternum, providing protection for the heart and lungs. Therefore, the correct answer is "All of the above" as all three options are part of the Skeletal System.

The correct answer is "All of the above." This means that all of the signs and symptoms listed in the options (exposed bone ends, deformity or angulation, pain and tenderness) can indicate a fracture.

The muscular system is composed of three main types of muscles: voluntary (skeletal) muscle, involuntary (smooth) muscle, and cardiac muscle. Voluntary muscles are under conscious control and are responsible for movements such as walking and lifting weights. Involuntary muscles are found in organs and blood vessels, and they work automatically to control bodily functions like digestion and blood flow. Cardiac muscle is a specialized type of muscle found only in the heart and is responsible for pumping blood throughout the body. Therefore, the correct answer is "All of the above" as it includes all three types of muscles that make up the muscular system.

In the case of open fractures, it is important to cover the wound with a sterile dressing. Open fractures occur when the broken bone punctures through the skin, leaving the wound exposed to potential infection. By covering the wound with a sterile dressing, it helps to prevent further contamination and reduce the risk of infection. Additionally, covering the wound can also help to control bleeding and provide some level of protection for the injured area.

The skeletal system serves two main functions: giving shape to the body and protecting vital internal organs. It provides support and structure to the body, allowing us to stand upright and move. Additionally, the bones of the skeleton act as a protective shield for organs such as the heart, lungs, and brain, preventing injury and damage. Therefore, the correct answer is "Both a & b."

An open fracture refers to a bone or joint injury where there is a break in the continuity of the skin. This means that the bone has pierced through the skin, leaving it exposed. Open fractures are also known as compound fractures and are considered more severe than closed fractures because they carry a higher risk of infection. Immediate medical attention is necessary for an open fracture to prevent further complications and to promote proper healing.

The muscular system has multiple functions. It gives shape to the body by providing support and structure. It also protects internal organs by surrounding and cushioning them. Additionally, the muscular system is responsible for movement, allowing the body to perform various actions and activities. Therefore, all of the given options - giving shape to the body, protecting internal organs, and providing movement - are correct functions of the muscular system.

The correct answer is to allow the patient to remain in a position of comfort after life threats have been controlled. This is important because it helps to minimize further injury and discomfort to the patient. By allowing them to remain in a position that feels comfortable to them, it can also help to reduce their anxiety and promote a sense of safety. Additionally, it is important to prioritize stabilizing life-threatening injuries before moving the patient or applying any other treatments.

The correct answer is "When in doubt, manually stabilize the injury." This means that if there is uncertainty about the severity or stability of the injury, it is important to manually stabilize it. This can help prevent further damage or complications until professional medical help arrives. It is a general guideline to follow when providing first aid or emergency care.
