Scoliosis, Kyphosis, and Lordosis: Comprehensive Nursing Notes
Scoliosis, Kyphosis, and Lordosis: Comprehensive Nursing Notes ( 15 Questions)
The patient asks about the pathophysiology of scoliosis.
Which explanation accurately describes the pathophysiology of scoliosis?
"Scoliosis results from an exaggerated inward curvature of the lower back." Rationale: This statement is not accurate. The description provided here more closely aligns with lordosis, not scoliosis. Scoliosis involves a sideways curvature of the spine, forming an 'S' or 'C' shape, as explained in choice C. Therefore, choice A is incorrect.
"Scoliosis causes an excessive forward curvature of the upper back." Rationale: This statement is not accurate. The description provided here more closely resembles kyphosis, not scoliosis. Kyphosis involves an excessive forward curvature of the upper back, while scoliosis involves a lateral or sideways curvature of the spine. Therefore, choice B is incorrect.
"Scoliosis involves a sideways curvature of the spine, forming an 'S' or 'C' shape." Rationale: This statement is accurate. Scoliosis is characterized by a lateral curvature of the spine, resulting in an 'S' or 'C' shape when viewed from the front or back. This lateral curvature can occur in various parts of the spine and can vary in severity. Therefore, choice C is correct.
"Scoliosis is primarily caused by poor posture and obesity." Rationale: This statement is not accurate. While poor posture and obesity may contribute to the progression of scoliosis in some cases, they are not the primary causes of the condition. Genetic factors and other underlying factors play a more significant role in the development of scoliosis. Therefore, choice D is incorrect.
Choice A rationale:
"Scoliosis results from an exaggerated inward curvature of the lower back." Rationale: This statement is not accurate.
The description provided here more closely aligns with lordosis, not scoliosis.
Scoliosis involves a sideways curvature of the spine, forming an 'S' or 'C' shape, as explained in choice C.
Therefore, choice A is incorrect.
Choice B rationale:
"Scoliosis causes an excessive forward curvature of the upper back." Rationale: This statement is not accurate.
The description provided here more closely resembles kyphosis, not scoliosis.
Kyphosis involves an excessive forward curvature of the upper back, while scoliosis involves a lateral or sideways curvature of the spine.
Therefore, choice B is incorrect.
Choice C rationale:
"Scoliosis involves a sideways curvature of the spine, forming an 'S' or 'C' shape." Rationale: This statement is accurate.
Scoliosis is characterized by a lateral curvature of the spine, resulting in an 'S' or 'C' shape when viewed from the front or back.
This lateral curvature can occur in various parts of the spine and can vary in severity.
Therefore, choice C is correct.
Choice D rationale:
"Scoliosis is primarily caused by poor posture and obesity." Rationale: This statement is not accurate.
While poor posture and obesity may contribute to the progression of scoliosis in some cases, they are not the primary causes of the condition.
Genetic factors and other underlying factors play a more significant role in the development of scoliosis.
Therefore, choice D is incorrect.
