Final answer:
The nursing assistant should report unusually yellow or white nails, which could indicate a fungal infection or other health issues. Pink nail beds usually represent healthy nails.
Step-by-step explanation:
The nursing assistant should report unusually yellow or white nails to the nurse. This could be a sign of a fungal infection or other health issues that may need attention. Nail beds that are pink usually indicate healthy nails, while yellow or white nails could suggest an underlying condition. Nail polish itself is not a health concern and well cared-for nails indicate good hygiene, so these are not typically reported unless the policy of the healthcare setting requires it.
