The nurse begins collecting the medical history of a child when the child screams and tries to hide behind the parent, dropping a stuffed toy. Which intervention should the nurse implement?

Infants with congenital heart defects may have difficulty with feeding due to increased effort required to breathe and feed at the same time. This can lead to poor weight gain and dehydration. Thus, it is important for the nurse to report any signs of poor feeding or oral intake to the healthcare provider. While audible heart murmur (choice A)and a high heart rate (choice B)are expected findings in infants with congenital heart defects, they do not necessarily indicate a need for immediate intervention. Weight gain of 2.2 lbs. (1 kg) in the last 48 hours (choice D)may actually be a positive finding in an infant with a congenital heart defect, but it is not as important to report as poor oral intake and suckling effort.

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.
