A nurse is assessing an adolescent client and observes an abnormal curvature of the thoracic spine, the client has scoliosis? Which finding should the nurse expect

Choice A reason: Scoliosis is clinically defined as a lateral, or sideways, curvature of the spine, often forming an "S" or "C" shape. In adolescents, this is frequently idiopathic and is detected during a physical exam by observing uneven shoulders, asymmetrical hip height, or a visible spinal curve. Choice B reason: When the anteroposterior diameter equals the transverse diameter, it is described as a barrel chest. This is typically a sign of chronic obstructive pulmonary disease (COPD) or air trapping, not a spinal deformity like scoliosis, and is unusual in an adolescent population. Choice C reason: A marked depression of the sternum is known as pectus excavatum, or funnel chest. This is a congenital structural deformity of the anterior chest wall and ribs, but it does not involve the lateral curvature of the vertebral column that characterizes a diagnosis of scoliosis. Choice D reason: Forward protrusion of the sternum and ribs is called pectus carinatum, or pigeon chest. Like pectus excavatum, this is a chest wall deformity. While it may occasionally coexist with other skeletal issues, it is not the defining characteristic of a scoliosis assessment.
