Cosmetology Test Nail Care and Services 4

Question 1

What nail condition appears as white spots or streaks on the nail plate and is usually caused by minor trauma to the nail matrix?

Accepted Answer

Leukonychia

Answer

Leukonychia (white spots) results from minor trauma or injury to the nail matrix that disrupts normal keratinization of the nail plate.

Question 2

When applying a base coat, how many strokes are typically used for each nail?

Accepted Answer

Two strokes on the sides followed by one down the center

Answer

The standard three-stroke method — two side strokes then one center stroke — ensures even, complete coverage of the nail plate with base coat.

Question 3

Which ingredient in nail hardeners cross-links the keratin proteins in the nail plate to strengthen it?

Accepted Answer

Formaldehyde

Answer

Formaldehyde (and its safer derivative toluene sulfonamide/formaldehyde resin) cross-links keratin proteins, hardening the nail plate.

Question 4

What is the purpose of a nail primer in acrylic nail application?

Accepted Answer

To improve adhesion between the natural nail and acrylic product

Answer

Nail primer chemically bonds to both the natural nail plate and the acrylic polymer, dramatically improving adhesion and reducing lifting.

Question 5

A client wants a pedicure but has a small open blister on their heel. What should you do?

Accepted Answer

Refuse the service and refer the client to a physician

Answer

An open wound is a contraindication for pedicure services because it poses infection risk to the client and cross-contamination risk in the spa.
