Final answer:
The nurse should assess the patient for the presence of pustules.
Step-by-step explanation:
Acne is a skin disturbance that typically occurs on areas of the skin that are rich in sebaceous glands (face and back). It is most common along with the onset of puberty due to associated hormonal changes, but can also occur in infants and continue into adulthood. The main sign of acne is the appearance of pimples (pustules) on the skin. Other signs of acne may include whiteheads, blackheads, nodules, and other lesions. The nurse should assess the patient for the presence of pustules, which are inflamed pimples filled with pus. These can be a characteristic indication of acne.
