Question

All of the following statements about the Wood's lamp are correct EXCEPT:

1) uses fluorescent light
2) identifies skin infection
3) identifies areas of oil production on the face
4) allows for identification of pigmentation conditions

Answer 1

The Wood's lamp uses fluorescent light to identify skin infections, as well as areas of oil production on the face and pigmentation conditions. Therefore, statement 2 is incorrect.

Step-by-step explanation:

The Wood's lamp is a diagnostic tool used by healthcare professionals to aid in the identification of certain skin conditions.

It uses fluorescent light with a wavelength of 365 nm.

When directed on the skin, the ultraviolet light emitted from the lamp causes certain elements, such as fungal elements in the case of tineas, to fluoresce. This helps in identifying skin infections such as ringworm.

Additionally, the Wood's lamp can also help in identifying areas of oil production on the face and allowing for identification of pigmentation conditions.

Therefore, statement 2, which says that the Wood's lamp does not identify skin infection, is incorrect.
