NIC Esthetician Written ExamScientific ConceptsEasy

A client presents with a localized, inflamed, pus-filled lesion on their chin. Upon closer inspection, the esthetician notes that the lesion is tender and has a noticeable head. Which of the following skin conditions does this most accurately describe?

  1. AWheal
  2. BPustule
  3. CMacule
  4. DBullae
Show answer & explanation

Correct answer: B. Pustule

A pustule is a small, inflamed, pus-filled lesion that often has a 'head,' matching the client's description perfectly. This primary lesion is characteristic of certain bacterial infections or acne.

Why the other options are wrong

  • A. A wheal is an itchy, swollen lesion caused by insect bites or allergies, often temporary and not typically pus-filled.
  • C. A macule is a flat, discolored spot on the skin, not elevated or pus-filled.
  • D. A bulla is a large blister containing watery fluid, larger than a pustule.

Pustule

A small, elevated, circumscribed lesion of the skin that contains pus.

  • Contains pus
  • Often associated with inflammation
  • Common in acne and bacterial infections

Memory trick: Primary lesions are the first signs, like a Pimple's Pus.
