Final answer:
The practical nurse should observe the sclera and mucous membranes when gathering data about a client with dark skin tones.
Step-by-step explanation:
When gathering data about a client with dark skin tones, the practical nurse should observe the sclera and mucous membranes. Dark skin tones can make it difficult to assess certain areas such as the hands and feet, forehead and face, or the finger and toe nails. However, the sclera (white part of the eyes) and mucous membranes (inside of the mouth) can provide important information about a client's health status.
