A client with Osteosarcoma asks the nurse about the pathophysiology of the disease.
Which response by the nurse is accurate?
"Osteosarcoma arises from mature bone-forming cells called osteocytes.”
"Genetic mutations leading to uncontrolled proliferation of osteoblasts contribute to Osteosarcoma.”
"Osteosarcoma typically starts in the epiphyseal region of long bones.”
"The tumor primarily extends into the muscle tissues surrounding the bone.”
The Correct Answer is B
Choice A rationale:
Osteosarcoma arises from mature bone-forming cells called osteocytes.
Rationale: This statement is not accurate.
Osteosarcoma does not originate from osteocytes.
Instead, it arises from osteoblasts, which are immature bone-forming cells.
Genetic mutations can lead to uncontrolled proliferation of osteoblasts, contributing to the development of Osteosarcoma.
Choice B rationale:
Genetic mutations leading to uncontrolled proliferation of osteoblasts contribute to Osteosarcoma.
Rationale: This statement is accurate.
Osteosarcoma is characterized by genetic mutations that cause osteoblasts to multiply uncontrollably, resulting in the formation of malignant bone tumors.
This is a key aspect of the disease's pathophysiology.
Choice C rationale:
Osteosarcoma typically starts in the epiphyseal region of long bones.
Rationale: This statement is not accurate.
Osteosarcoma usually begins in the metaphyseal region of long bones, not the epiphyseal region.
The metaphysis is the area of the bone where growth occurs, making it more susceptible to malignant changes.
Choice D rationale:
The tumor primarily extends into the muscle tissues surrounding the bone.
Rationale: This statement is not accurate.
Osteosarcoma primarily affects the bone itself, with the tumor originating within the bone tissue.
While it can extend into nearby soft tissues, such as muscles, it does not primarily start in muscle tissues.

Correct Answer is B
Explanation
Choice B rationale:
The most appropriate advice for Osteosarcoma prevention strategies is to undergo regular medical surveillance.
Osteosarcoma is primarily a genetic condition, and there are no specific lifestyle changes or dietary modifications that can prevent its development.
Regular medical check-ups and surveillance can help in early detection and intervention if there are any signs or symptoms of the disease.
Choice A rationale:
Avoiding physical therapy is not a relevant or appropriate prevention strategy for Osteosarcoma.
Physical therapy is a valuable component of rehabilitation and may be beneficial for patients with Osteosarcoma to regain function and mobility after treatment.
Choice C rationale:
Increasing exposure to radiation is not a recommended prevention strategy for Osteosarcoma or any other condition.
Radiation exposure can increase the risk of cancer, and unnecessary radiation should be avoided.
Choice D rationale:
Consuming a diet high in calcium is not a specific prevention strategy for Osteosarcoma.
While calcium is important for bone health, Osteosarcoma is primarily a genetic condition, and dietary factors are not known to be a significant risk factor.
Choice E rationale:
Using over-the-counter medicine…
Correct Answer is B
Explanation
Choice A rationale:
"To perform limb-sparing surgery." Chemotherapy is administered before surgery (neoadjuvant chemotherapy) to shrink the tumor and make limb-sparing surgery possible in cases of Osteosarcoma.
The primary goal is to reduce the size of the tumor and improve the chances of successful surgical removal while preserving the affected limb.
Choice C rationale:
"To remove the palpable mass." While surgery is intended to remove the palpable mass, chemotherapy is not given for the sole purpose of mass removal.
Chemotherapy is used as part of a multimodal treatment approach to target cancer cells systemically and reduce the tumor's size before surgery.
Choice D rationale:
"To administer radiation therapy." Chemotherapy is not the primary treatment for administering radiation therapy in Osteosarcoma cases.
Radiation therapy is typically considered when there is residual disease after surgery or in cases where surgery is not possible.
