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.

Answer and Explanation

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 A

Explanation

Choice A rationale

Scoliosis is characterized by a lateral curvature of the spine, often identified by uneven shoulders and a prominent scapula. The forward bending test accentuates these physical signs, helping to diagnose scoliosis.

Choice B rationale

Muscular dystrophy involves progressive muscle weakening and wasting, typically symmetrical, not causing the asymmetry seen in scoliosis. It usually doesn't present with the specific spinal curvature of scoliosis.

Choice C rationale

Kyphosis involves a forward rounding of the upper back, not a lateral curvature. It presents as a hunched or rounded back rather than uneven shoulders and prominent scapula.

Choice D rationale

Lordosis refers to an exaggerated inward curve of the lower back, not involving uneven shoulders or scapula. It affects the lumbar spine rather than presenting the scoliosis-related signs described.

A. Aspiration of synovial fluid for serologic testing. B. Injection of corticosteroids into the client's knee joint to facilitate ROM. C. Injection of a contrast agent into the knee joint prior to ROM exercises. D. Replacement of the client's synovial fluid with a synthetic substitute. E. Replacement of the client's synovial fluid with a synthetic substitute.

Correct Answer is C

Explanation

Choice A rationale

Aspiration of synovial fluid for serologic testing is a procedure known as arthrocentesis, which involves extracting joint fluid for analysis. While useful for diagnosing conditions like infections or arthritis, it is not the same as arthrography, which involves imaging.

Choice B rationale

Injection of corticosteroids into the client's knee joint to facilitate ROM is a therapeutic procedure to reduce inflammation and improve movement in conditions like arthritis, but it is not part of an arthrography procedure.

Choice C rationale

Injection of a contrast agent into the knee joint prior to ROM exercises is a key part of arthrography. The contrast agent helps to enhance the imaging of the joint structures during movement, allowing for a detailed assessment of the joint.

Choice D rationale

Replacement of the client's synovial fluid with a synthetic substitute is not related to arthrography. This description aligns more with viscosupplementation, a treatment for osteoarthritis.
