A nurse is assessing a pediatric client who is exhibiting manifestations of rhabdomyosarcoma. In which area of the body should the nurse expect to find a tumor?

A. Spine: Rhabdomyosarcoma rarely originates in the spine. While metastasis can occur to various sites, the spine is not a common primary location for this tumor in pediatric clients. B. Head: Rhabdomyosarcoma most frequently arises in the head and neck region, including the orbit, nasopharynx, and paranasal sinuses. Tumors in this area often present with swelling, proptosis, or nasal obstruction, reflecting the typical manifestation sites in children. C. Ribs: The ribs are an uncommon site for primary rhabdomyosarcoma. While thoracic involvement may occur secondary to metastasis, initial tumors in this location are rare. D. Upper leg: Extremities can be affected by rhabdomyosarcoma, but the head and neck region is the most prevalent site. Tumors in the limbs are less common, though they may present with swelling or functional impairment if they occur there.
