A child diagnosed with Kawasaki disease is brought to the clinic. The mother reports that her child is irritable, refuses to eat, and has skin peeling on both hands and feet.

Which intervention should the nurse instruct the mother to implement first?

The adolescent client's symptoms of localized pain, swelling, and tenderness, particularly at night, are suggestive of a malignancy such as osteosarcoma, which is the most common primary bone tumor in children and adolescents.

Radial ossification in the soft tissues is a characteristic finding in osteosarcoma and is indicative of bone production by malignant cells. Other imaging modalities, such as X-rays, computed tomography (CT), and magnetic resonance imaging (MRI), may also reveal osteolytic or osteoblastic lesions in the bone.

Growing pains are a common, benign condition that occur in children and do not typically present with the

symptoms described in the case scenario.

Rhabdomyolysis is a medical emergency that involves the breakdown of skeletal muscle tissue and release of muscle fiber contents into the bloodstream. It can present with muscle pain, swelling, and tenderness, but typically occurs as a result of injury, infection, or drug toxicity.

Hemosiderosis is a rare condition characterized by the accumulation of iron in various tissues, including the liver, spleen, and bone marrow. It may present with symptoms such as fatigue, joint pain, and abdominal pain, but is not typically associated with the symptoms and imaging findings described in the case scenario.

Therefore, the nurse should consider osteosarcoma as the probable cause of the adolescent client's symptoms and imaging findings, and should collaborate with the healthcare team to develop a plan of care for diagnosis and treatment.

During the initial phase of treatment for osteomyelitis, the nurse should instruct the child and parent to ensure that there is no weight bearing on the affected extremity. This may require the use of assistive devices such as crutches or a wheelchair. Administering topical antibiotic therapy, providing passive range of motion exercises, and scheduling ice pack applications to the infected area are not appropriate interventions during the initial phase of treatment.

Topical antibiotics may be used later in the course of treatment, after the initial phase of intravenous antibiotics has been completed.

Passive range of motion exercises may be appropriate during the later phases of treatment to prevent joint contractures.

Ice pack applications may be appropriate for pain relief, but they are not a primary intervention for osteomyelitis.
