A nurse is giving a preoperative patient a dose of famotidine ( Pepcid). The patient asks why the nurse is giving this drug when the patient has no history of ulcers. What response by the nurse is best?

A. Melanoma:

Melanoma is a type of skin cancer that arises from melanocytes, the cells that produce pigment (melanin) in the skin. Melanoma lesions are typically irregularly shaped, often asymmetrical, with varying shades of color (brown, black, tan, red, blue). They may have an uneven border and can evolve over time. Melanomas can be raised but are not typically described as indurated (firm) and shiny. They are also more commonly associated with changes in color, size, and shape.

B. Keloid:

A keloid is an abnormal overgrowth of scar tissue that extends beyond the boundaries of the original wound or incision site. Keloids are characterized by their raised appearance, firm or indurated texture, and shiny surface compared to the surrounding skin. They may also be darker than the surrounding skin due to increased collagen deposition. Keloids can develop months after an injury or surgery and are more common in individuals with darker skin tones, such as African Americans.

C. Nevus:

A nevus, commonly known as a mole or birthmark, is a benign growth of melanocytes or other skin cells. Nevus lesions can vary in appearance but are often flat or slightly raised, with a uniform color (brown, black, tan, or flesh-colored). They are usually not described as indurated or shiny. Nevus lesions can be present at birth (congenital nevus) or develop later in life (acquired nevus).

D. Angioma:

Angiomas are benign tumors that originate from blood vessels or lymphatic vessels. They can present as red or purplish raised lesions on the skin. Angiomas are typically not described as indurated or shiny. Common types of angiomas include cherry angiomas (small, red papules) and spider angiomas (red, spider-like lesions with central vessels).

A. Cluster of oral herpes sores: Oral herpes sores typically heal within a few weeks and do not generally become chronic wounds unless there are complications or underlying immune system issues. They are more acute in nature and tend to resolve without becoming chronic.

B. Abdominal surgical incision: Surgical incisions are designed to heal within a specific timeframe, usually a few weeks to a couple of months, depending on the type of surgery and individual healing factors. While surgical wounds can sometimes have delayed healing or complications, they are not typically categorized as chronic wounds unless they fail to heal or become recurrent over an extended period.

C. Diabetic foot ulcer: Diabetic foot ulcers are highly prone to becoming chronic wounds due to the underlying pathology associated with diabetes, such as neuropathy (nerve damage), peripheral vascular disease (poor circulation), and impaired immune function. These factors can impair the normal healing process, leading to delayed healing, infection, and the potential for the wound to become chronic if not managed appropriately.

D. Posterior scalp wound: Scalp wounds can heal relatively quickly, especially with proper wound care and management. However, certain factors such as the size of the wound, depth, presence of infection, and underlying conditions can influence the likelihood of a scalp wound becoming chronic. In general, scalp wounds are less likely to become chronic compared to wounds in areas with higher risk factors, such as diabetic foot ulcers.
