The nurse suspects that an older adult patient has features of basal cell carcinoma appearing in form of a small dome-shaped lesion with a pearly surface on the face.
What is Basal cell carcinoma?
The most prevalent type of skin cancer that is not melanoma is basal cell carcinoma (BCC).
- It is a tumour that causes localized damage and has a variety of clinical and histological characteristics.
- When viewed at low power magnification, a basaloid epithelial tumour emerging from the epidermis is the primary characteristic of basal cell carcinoma.
- Normally, the palisade-like basaloid epithelium forms a fissure from the surrounding tumour stroma.
The nuclei grow congested in the centre, with scattered mitotic figures and visible necrotic bodies.
The presence of a mucinous stroma serves as a helpful distinguishing factor from other basaloid cutaneous tumours. Additionally, some tumours may exhibit foci of regression, which are regions of eosinophilic stroma devoid of basaloid nests.
Hence, the answer is a small dome-shaped lesion with a pearly surface on the face.

The urine volume would enhance if ADH was not added to the collecting duct. This is because the ADH works on the collecting ducts where the increase permeability for water is improved, so less water is perspired into the urine, so urine evolves more concentrated.
<h3>What happens to urine volume when ADH advances?</h3>
- ADH improves the permeability to water of the distal serpentine tubule and collecting duct, which is normally impervious to water. This effect causes heightened water reabsorption and retention and reduces the volume of urine produced comparable to its ion content.
- In SIADH, the body is unable to subdue the secretion of ADH, conducting to insufficient water excretion and reduced urine output. Normally, when water is ingested, serum tonicity and osmolality reduction, and ADH are quelled, resulting in an output of dilute (less concentrated) urine.
- A hormone that allows blood vessels narrow and helps the kidneys control the portion of water and salt in the body. This enables the control of blood pressure and the quantity of urine that is made. Antidiuretic hormone is made by a portion of the brain called the hypothalamus and is perspired into the blood by the pituitary gland.

Answer: B, health and safety. Hopefully that helps!
Preventative medicine is a medical specialty that is involved in the healthy of individuals and communities. The major goal of preventative medicine is to encourage the health and well-being of others. As well as prevent death, disease and disabilities. A couple of examples of preventative medicine would be childhood immunizations and screening for hypertension.
