Final answer:
The abbreviation for Brief Resolved Unexplained Episode is BRUE. It refers to a sudden, brief episode in an infant, which resolves on its own and has no obvious cause after examination.
The correct option is 2.
Step-by-step explanation:
A Brief Resolved Unexplained Episode (BRUE) is a term used in pediatric medicine to describe an event occurring in an infant less than one year of age that is sudden, brief, and unexplained.
BRUEs are characterized by a change in the infant's color, tone, breathing, or responsiveness that prompts parents or caregivers to seek medical attention.
The purpose of using the term BRUE is to describe a single episode that is not immediately associated with a clear cause, such as an infection or trauma. It is important for healthcare providers to evaluate infants who experience a BRUE to rule out serious underlying conditions.
BRUEs were formerly referred to as "apparent life-threatening events" (ALTE), but the term was changed to BRUE to reflect the uncertainty regarding the actual threat to the infant's life during such episodes.
The goal is to conduct a thorough medical evaluation to determine the cause of the episode and provide appropriate care for the infant.
The correct option is 2.
