Final answer:
In the patient's EHR, specifically in the neurological assessment section, document the slurred speech by adding a comment describing the abnormality, its onset, and any additional relevant information.
Step-by-step explanation:
When documenting in a patient's electronic health record (EHR), such as EPIC, after determining that Kingsley's speech is slurred, it is important to choose the appropriate section to record your clinical findings. In this case, the correct documentation would be option B. This option allows you to add a comment clearly describing the observed abnormality. You should go to the neurological assessment section and use the available tools to add detailed notes. Here, you describe the slurred speech, its onset, and any additional relevant details. Abbreviated terms like 'WDL' (Within Defined Limits) would not be appropriate in this case, since slurred speech is an exception to normal function, and marking it as 'X' would also require you to add a comment to specify the nature of the exception.
