Juvenile arthritis should be suspected in a child who exhibits

During painful episodes of juvenile arthritis, a plan of care should include proper positioning of the affected joints to prevent musculoskeletal complications. Proper positioning helps to alleviate pain, reduce inflammation, and minimize stress on the affected joints. It also promotes joint stability and prevents contractures or deformities that can occur due to prolonged immobility.

a weight-control diet to decrease stress on the joints in (option A) is incorrect because it, may be a consideration in managing overall joint health and reducing excessive strain on the joints. However, it is not the primary nursing intervention during painful episodes of juvenile arthritis.

high-resistance exercises to maintain muscular tone in the affected joints in (option C) is incorrect because it, may not be appropriate during painful episodes of juvenile arthritis. High-resistance exercises can potentially exacerbate pain and inflammation. Exercise should be tailored to the individual's condition and guided by healthcare professionals.

complete bed rest to decrease stress to joints in (option D) is incorrect because it, is not recommended as a nursing intervention for painful episodes of juvenile arthritis. Prolonged bed rest can lead to muscle weakness, joint stiffness, and functional decline. Instead, maintaining mobility and appropriate activity levels within the child's pain tolerance and capabilities is generally preferred.

A change in status that should alert the nurse to increased intracranial pressure (ICP) in a child with a head injury is confusion and altered mental status. As intracranial pressure increases, it can affect brain function and lead to neurological changes, including confusion, disorientation, irritability, decreased level of consciousness, or other alterations in mental status. These changes indicate that the brain is being compressed and compromised, and immediate intervention is required.

Option B, increased diastolic pressure with narrowing pulse pressure in (option B) is incorrect because it, can be a sign of increased ICP, but it is not specific to head injuries and can be influenced by other factors such as pain, anxiety, or systemic conditions. It is important to consider the overall hemodynamic status of the child and assess for additional signs and symptoms of increased ICP.

irregular, rapid heart rate in (option C), can be a sign of increased ICP, but it is not specific to head injuries and can be influenced by other factors such as pain, anxiety, or other medical conditions. Assessment of heart rate should be considered along with other signs and symptoms of increased ICP.

rapid, shallow breathing, in (option D) can be a sign of increased ICP, but it is not specific to head injuries and can be influenced by other factors such as pain, anxiety, or respiratory conditions. Respiratory assessment should be considered along with other signs and symptoms of increased ICP.
