The nurse is assessing a child with acute glomerulonephritis who presents with increased fatigue, facial puffiness, decreased appetite. The child's urine sample is dark yellow in color.

Which additional finding should the nurse report to the healthcare provider?

Biliary atresia is a condition that can cause jaundice in newborns and infants, and it can also lead to tea-colored urine due to the presence of bilirubin in the urine. Infants with biliary atresia require further assessment and treatment, including possible surgery, to prevent liver damage and other complications.

A. Intussusception is a condition in which a part of the intestine folds into itself, causing an obstruction, but it does not typically present with jaundice or tea-colored urine.

C. Hirschsprung's disease is a congenital condition that affects the large intestine and can cause bowel obstruction, but it also does not typically present with jaundice or tea-colored urine.

D. Huntington's disease is a genetic neurological disorder that typically does not present in infants and does not cause jaundice or tea-colored urine.

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.
