NIC Nail Technician Written ExamScientific ConceptsHard
A client notices that their toenails are often discolored with a yellowish-green hue, and the nails appear thick and slightly lifted. They also mention a slightly foul odor.

- APseudomonas aeruginosa
- BStaphylococcus aureus
- CStreptococcus pyogenes

Show answer & explanationAnswer & explanation
Correct answer: A. Pseudomonas aeruginosa
Pseudomonas aeruginosa is a common bacteria that causes a characteristic yellowish-green discoloration of the nail plate, often accompanied by thickening, lifting, and sometimes a foul odor. This infection is frequently seen when moisture is trapped between the natural nail and an artificial nail or enhancement, providing an ideal environment for the bacteria to thrive.
Why the other options are wrong
- B. Staphylococcus aureus can cause various skin infections but is not typically associated with the green nail discoloration.
- C. Streptococcus pyogenes causes strep throat and other skin infections, not typically green nail syndrome.
- D. Escherichia coli is primarily an intestinal bacterium and not a common cause of nail infections with this specific presentation.
