Final answer:
Sundry skin lesions can include formations such as papules, conditions like eczema, types of skin cancer like melanoma, and damage to the skin such as ulcers. Healthcare workers can transmit infections like MRSA even if they are asymptomatic.
Step-by-step explanation:
Examples of sundry skin lesions include a variety of changes in skin appearance or texture. Some examples provided in the question can be categorized under specific types:
- A) Papule, nodule, and cyst: These terms describe the form and size of lesions. A papule is a small raised bump on the skin, a nodule is larger and deeper than a papule, and a cyst is a lesion that resembles a cyst but with a less defined boundary, often fluid- or pus-filled.
- B) Eczema, psoriasis, and dermatitis: These are types of skin disorders, with eczema and psoriasis being inflammatory conditions. Dermatitis is an umbrella term for skin inflammation. Acne, mentioned within the context, involves the clogging of pores which can lead to infection and inflammation.
- C) Melanoma, basal cell carcinoma, and squamous cell carcinoma: These are types of skin cancer. Basal cell carcinoma and squamous cell carcinoma are common and are less likely to metastasize, while melanoma is more dangerous and likely to spread to other body parts.
- D) Ulcer, fissure, and petechiae: These refer to specific types of damage to the skin. An ulcer is a deep sore or open wound, a fissure is a crack in the skin, and petechiae are small, round spots that appear due to bleeding under the skin.
While answering a student's question about skin lesions, it is essential to provide accurate and easy-to-understand descriptions of each term, using examples when possible. A healthcare worker who is asymptomatic can still transmit bacteria such as MRSA to patients through direct contact or by contaminating surfaces that patients may later come in contact with.
