A nurse is caring for a child who has retinoblastoma that has potentially metastasized to the brain. Which of the following diagnostic tests should the nurse anticipate for determining if metastasis of the brain has occurred?

A. "Adolescents are critical thinkers and can distinguish between accurate health information and misleading media content.": While some adolescents develop critical thinking skills, many lack the experience to consistently evaluate the accuracy of health-related media, making them vulnerable to misinformation.

B. "Media can play a significant role in shaping adolescents' perception of health, as it can both inform and misinform them about various health issues.": Media exposure significantly influences adolescents’ beliefs, attitudes, and behaviors related to health. Social media, television, and online content can provide education but also spread misinformation, affecting decisions about nutrition, exercise, substance use, and mental health.

C. "Adolescents are not easily influenced by media when it comes to health concerns. They rely on health care professionals for accurate information.": Adolescents often turn to peers and media for health information and may not consistently consult healthcare professionals. Dismissing media influence underestimates its impact on health perceptions and behavior.

D. "Media has no impact on adolescents' health perceptions: their attitudes are solely shaped by their peers.": Peer influence is important, but media plays a significant and measurable role in shaping adolescent health beliefs, choices, and behaviors. Ignoring media impact provides an incomplete understanding of adolescent health education needs.

A. High levels of cerebrospinal fluid (CSF): Spina bifida is a neural tube defect involving incomplete closure of the vertebral column rather than abnormal CSF production. Elevated CSF levels are not a defining feature and are not used as a screening indicator. CSF abnormalities are more relevant to hydrocephalus assessment.

B. Increased intracranial pressure (ICP): Elevated ICP may occur secondary to associated conditions such as hydrocephalus, but it is not an initial or direct sign of spina bifida. The defect itself is identified by spinal and cutaneous findings. ICP changes develop later if complications arise.

C. Indications of infection: Infection is a potential complication if neural tissue is exposed, but it is not an initial indicator prompting suspicion of spina bifida. Early recognition relies on visible spinal or skin markers. Infection suggests a secondary problem rather than the congenital defect.

D. Presence of a small dimple and a tuft of hair over the lower lumbar region: Cutaneous stigmata such as a sacral dimple, hair tuft, or discoloration are classic indicators of underlying spinal dysraphism. These findings warrant further evaluation for spina bifida occulta. They are key clues during newborn and infant assessment.
