A patient has a lesion in the left axilla that is deep, painful, and contains pus. It is 3 centimeters in diameter. After the assessment, what type of lesion should the nurse determine that the patient has?
1. furuncle
2. folliculitis
3. carbuncle
4. herpes varicella
Correct Answer: 1
A furuncle develops when the infection from folliculitis becomes deeper. It is initially a deep, firm, red, painful nodule from 1 to 5 cm in diameter. In folliculitis, a sebaceous gland is obstructed, causing a deep inflammatory reaction and infection most commonly from S. aureus. The lesions appear as pustules surrounded by an area of erythema on the surface of the skin and are accompanied by discomfort ranging from slight burning to intense itching. A carbuncle is a group of infected hair follicles that interconnect. It is about 3 to 10 centimeters in diameter. Herpes varicella (chickenpox) lesions are superficial and usually limited to the face, scalp, and chest.
