Final answer:
During a medical exam, 'WNL' or 'NAD' is used to document normal findings in an organ system, and any abnormalities require detailed elaboration.
Step-by-step explanation:
When documenting an exam, a provider may notate ‘WNL’ (Within Normal Limits) or ‘NAD’ (No Abnormalities Detected) for body areas or organ systems that are normal. Elaboration on abnormalities is required. This form of documentation allows healthcare providers to quickly convey the state of an examined body area or organ system. If abnormalities are identified in specific structures such as organs, anatomical regions, or in the functionality of the sensory systems, detailed notes need to be included in the patient's medical record. These could include observations of reduced muscular strength, sensory deficits, or any other abnormal findings that might indicate potential health issues requiring further investigation or immediate intervention.
