A client has sustained traumatic injuries that involve several bone fractures. A fracture of what type of bone may interfere with the protection of the client's vital organs?
Irregular bones.
Flat bones.
Long bones.
Short bones.
The Correct Answer is B
Choice A rationale
Irregular bones have complex shapes that do not fit into the other categories (long, short, or flat bones). They include bones such as the vertebrae and facial bones, which have specialized functions but are not primarily responsible for protecting vital organs.
Choice B rationale
Flat bones, such as the sternum, ribs, and skull bones, are designed to protect vital organs. They provide broad surfaces for muscle attachment and serve as protective barriers for organs like the brain, heart, and lungs.
Choice C rationale
Long bones, such as the femur and humerus, are primarily responsible for supporting the weight of the body and facilitating movement. While they contribute to the overall structure of the body, they are not specifically designed for organ protection.
Choice D rationale
Short bones, such as the carpals and tarsals, provide support and stability with limited movement. They are not primarily involved in the protection of vital organs.

Correct Answer is B
Explanation
Choice A rationale
Lordosis is an exaggerated inward curvature of the lumbar spine. It is commonly seen in pregnant women, individuals with obesity, or those with weak abdominal muscles. Lordosis is not characterized by an increased thoracic curvature.
Choice B rationale
Kyphosis is an exaggerated outward curvature of the thoracic spine, often resulting in a hunched or rounded back. It is commonly seen in older adults due to osteoporosis, degenerative disc disease, or poor posture. Kyphosis is the correct diagnosis for increased thoracic curvature.
Choice C rationale
Scoliosis is a lateral curvature of the spine, often resembling an "S" or "C" shape when viewed from behind. It can occur in any part of the spine but does not specifically describe an increased thoracic curvature.
Choice D rationale
Epiphyses refer to the growth plates at the ends of long bones in children and adolescents. They are not related to spinal curvature or any spinal disorder. .
Correct Answer is C
Explanation
Choice A rationale
The peripheral nervous system (PNS) consists of all the nerves outside the brain and spinal cord. It transmits signals to and from the central nervous system but does not specifically regulate energy expenditure.
Choice B rationale
The parasympathetic nervous system is part of the autonomic nervous system that promotes "rest and digest" functions, conserving energy by slowing the heart rate and increasing intestinal and gland activity.
Choice C rationale
The sympathetic nervous system is responsible for the "fight or flight" response, which prepares the body to expend energy rapidly in response to perceived threats. It increases heart rate, dilates airways, and mobilizes energy stores.
Choice D rationale
The central nervous system (CNS) consists of the brain and spinal cord. It is responsible for processing information and coordinating bodily functions but does not specifically regulate energy expenditure.
