Final answer:
When making a mistake while charting manually, draw a single line through the error, label it as 'error', and add your initials with the date; the original entry should remain legible.
Step-by-step explanation:
If you make a mistake while charting manually, it is important to correct the error according to the protocol of your healthcare facility. Generally, you should draw a single line through the mistake, write 'error' alongside it, and then initial and date the correction. Avoid using correction fluid or erasing the error, as the original entry must remain legible. Make the correction as soon as the error is noticed to maintain the accuracy and integrity of the medical record.
