A nurse is assessing a toddler who has infective endocarditis. Which of the following findings should the nurse expect?

A. Oucher pain rating scale: The Oucher pain rating scale uses pictures of children's faces to represent varying degrees of pain intensity. This scale is specifically designed for young children and can be effective in assessing pain in preschool-aged children who may not yet be able to accurately use verbal descriptors to express their pain.

B. Word-Graphic rating scale: This type of scale presents both words and pictures to represent different levels of pain intensity. While it may be suitable for older children who can understand and use words to describe their pain, it may be less effective for a 4-year-old child who is still developing language skills.

C. Numeric rating scale: Numeric rating scales typically ask the child to rate their pain on a scale from 0 to 10, with 0 representing no pain and 10 representing the worst pain imaginable. While this scale may be appropriate for older children, it may be challenging for a 4-year-old to understand and use numbers to describe their pain.

D. Visual analog scale: Visual analog scales typically consist of a line with endpoints labeled "no pain" and "worst pain imaginable," with the child asked to mark or point to the spot on the line that represents their pain level. While this scale may be suitable for older children and adults, it may be too abstract for a 4-year-old child to understand and use effectively.

A. "Reye syndrome causes fatty changes in the liver."

This statement is correct. Reye syndrome is characterized by acute non-inflammatory encephalopathy and fatty changes in the liver, which can lead to liver dysfunction and failure.

B. "Reye syndrome leads to venous thrombus formation."

This statement is incorrect. Reye syndrome primarily affects the brain and liver, leading to cerebral edema and liver dysfunction. It does not typically involve venous thrombus formation.

C. "Reye syndrome is associated with misuse of acetaminophen."

This statement is incorrect. While the exact cause of Reye syndrome is not fully understood, it is not associated with the misuse of acetaminophen. However, there is a well-established association between Reye syndrome and the use of aspirin (salicylates) during viral infections, particularly in children and adolescents.

D. "Reye syndrome is linked to decreased serum ammonia levels."

This statement is incorrect. Reye syndrome is associated with increased serum ammonia levels due to liver dysfunction and impaired ammonia metabolism. Elevated ammonia levels can contribute to the encephalopathy seen in Reye syndrome.
