Which skin structures are responsible for fingerprints?

Eating large amounts of turnips and beets can lead to a condition called beeturia, which causes the urine and skin to turn a reddish or purplish color. This condition is harmless and is caused by the betalain pigments present in these vegetables. As a strict vegetarian, it is possible that the client consumes large amounts of these vegetables, which could explain the unusual skin color.

Rice and eggs, carrots and squash, spinach and mustard greens are not known to cause unusual skin color. However, it is important for the nurse to ask the client about her diet and any supplements she may be taking to beter understand the cause of the unusual skin color.

The ABCD rule is a mnemonic used to identify the characteristics of melanoma, which is a type of skin cancer. The leters stand for:

A -Asymmetry: One half of the mole or lesion does not match the other half.

B - Border irregularity: The edges are ragged, notched, or blurred.

C - Color: The color is not uniform and may include different shades of brown or black, or sometimes patches of pink, red, white, or blue.

D - Diameter: The size of the mole or lesion is greater than 6 mm (about the size of a pencil eraser), although melanomas can sometimes be smaller.

This rule is not as useful in detecting other types of skin cancer, such as squamous cell carcinoma, basal cell carcinoma, or sarcoma, as they tend to have different characteristics. However, any new or changing mole or lesion on the skin should be examined by a dermatologist to determine if it is cancerous.
