What is the purpose of the acronym 'PEARL' in patient assessment?

The acronym 'PEARL' is specifically used to evaluate pupil response during a patient assessment. It stands for Pupils Equal And Reactive to Light. This assessment is crucial as it provides immediate information about the neurological status of the patient. By shining a light in each eye, EMTs can observe whether the pupils constrict appropriately, which indicates the functioning of the brain and optic nerve. Changes in pupil size and reaction can suggest various conditions, such as increased intracranial pressure or drug effects, making this a vital component of a thorough evaluation.

The other options do not align with the function of 'PEARL' in a patient assessment context, as they pertain to different aspects of diagnostic evaluation that are not related to pupil reaction.
