The client inquires what the positive result from the potassium hydroxide (KOH) test indicates. Which of the following is an accurate response by the nurse?

Choice A Reason: This is correct because melanoma is a type of skin cancer that arises from melanocytes, which are cells that produce pigment. Melanoma lesions are often irregular in shape and color, and may have different shades of brown or black.

Choice B Reason: This is correct because melanoma is a very aggressive and invasive type of skin cancer that can spread quickly to other parts of the body through the blood or lymphatic system. Melanoma has a high mortality rate if not detected and treated early.

Choice C Reason: This is incorrect because warm and red skin around a lesion may indicate inflammation or infection, but not necessarily melanoma. Melanoma lesions may have other signs, such as bleeding, itching, or ulceration.

Choice D Reason: This is correct because melanoma is associated with exposure to ultraviolet (UV) radiation from sunlight or artificial sources, such as tanning beds. UV radiation can damage the DNA of melanocytes and cause them to grow abnormally.

Choice E Reason: This is incorrect because melanoma lesions are usually not painful unless they are ulcerated or infected. Pain may be a sign of other types of skin conditions, such as burns, blisters, or cuts.

Choice A Reason: Inserting a nasal swab to observe the fluid is contraindicated, as it can introduce infection or increase intracranial pressure. The fluid can be tested for glucose or halo sign to confirm cerebrospinal fluid (CSF) leakage.

Choice B Reason: Suctioning the nose gently with a bulb syringe is also contraindicated, as it can create negative pressure and increase CSF leakage or cause meningitis.

Choice C Reason: This is the correct answer because allowing the drainage to drip onto a sterile gauze pad can prevent contamination and facilitate observation of the amount and characteristics of the fluid.

Choice D Reason: Inserting sterile packing into the nares is not recommended, as it can obstruct the drainage and increase intracranial pressure or infection risk.
