A nurse is caring for a child who is suspected of having Legg-Calve-Perthes disease.

The nurse should prepare the child for which of the following diagnostic procedures?

Bone biopsy.

Radiographs.

MRI.

Genetic testing.

Answer and Explanation

The Correct Answer is B

Radiographs are vital to the diagnosis of Legg-Calve-Perthes disease.
Initial X-rays might look normal because it can take one to two months after symptoms begin for the changes associated with Legg-Calve-Perthes disease to become evident on X-rays.
The doctor will likely recommend several X-rays over time, to track the progression of the disease.

Bone biopsy is not a diagnostic procedure for Legg-Calve-Perthes disease.
MRI can visualize bone damage caused by Legg-Calve-Perthes disease more clearly than X-rays can but are not always necessary.
Genetic testing is not a diagnostic procedure for Legg-Calve-Perthes disease.
