HUBS 7 Flashcards
folliculitis
When hair follicles gets inflamed, usually because of a bacterial infection. It causes small, pus filled bumps with red skin around them.
furuncles (boils)
painful, pus-filled lumps that form when a hair follicle infection spreads deeper in the skin.
carbuncles
collections of infected hair follicles. The infection goes deeper into the skin, causing large, red or dark painful lumps that can drain pus from several spots.
cellulitis
fast-spreading bacterial infection of the dermis. It happens more often in older adults, but can happen in children aswell.
signs & symptoms of cellulitis
-skin redness
-swelling
-pain
treatment of cellulitis
-treated with antibiotics
-elevation (if in leg)
-IV in hospital (for serious infection)
prevention of cellulitis
keep skin wound clean with bandage and use antibiotic cream for protection
dermatitis (eczema)
most common type of inflammation of skin. itchiness, redness, and a rash
Acne vulgaris
When oil glands in the skin get inflamed. it causes spots like pimples, cysts and pus-filled bumps.
psoriasis
a chronic skin condition caused by the immune system. it makes skin cells grow too quickly, leading to thick, red patches.
basal cell carcinoma
a type of skin cancer that starts in the basal cells of the skin often in areas that get a lot of run. It is slow-growing and rarely spreads to other parts of the body.
squamous cell carcinoma
A type of skin cancer that starts in the outer layer of the skin. It appears as a lump that may turn into a sore with an uneven edge that doesn’t heal and can bleed easily.
melanoma
A serious type of skin cancer that starts in pigment-producing cells (melanocytes). it can grow and spread quickly, and is caused by both genetic and environmental factors. Although it’s often linked to sun exposure, melanoma can appear anywhere on the skin.
pressure injury
damage to the skin and tissues underneath caused by constant pressure. When someone sits or lies in one position for too long, the pressure can squeeze small blood vessels between the bone and a surface.
what is the first stage of pressure injury
the skin isn’t broken but looks red or discolored and doesn’t turn white when pressed (non-blanchable).
what is the second stage of pressure injury
The top layer of skin is damaged, showing the layer underneath. It may look like a blister or shallow open sore.
what is the third stage of pressure injury
the damage goes through the full thickness of the skin and reaches the fat layer (hypodermis). The sore may have rolled edges
what is the fourth stage of pressure injury
the injury is very deep, reaching muscles, tendons, bones or other deeper tissues.
what is the unstageable stage of pressure injury
The skin is completely broken down, but the full extent can’t be seen because dead tissue is covering it.
what is the deep tissue injury stage of pressure injury
damage happens below the surface of the skin. It may look dark red, purple, maroon, or like a blood-filled blister. The skin might still be intact or starting to break down.
leg ulcers
A deep sore caused by full-thickness skin loss anywhere on the lower leg. Happens because of poor blood flow in the veins or arteries, or due to nerve problems.
venous leg ulcers
open sores on the lower leg, often between the knee and ankle, that are slow to heal due to impaired blood flow in the veins
arterial leg ulcers
open sores on the legs and feet caused by reduced blood flow.
differences between venous leg ulcers and arterial leg ulcers:
- arterial leg ulcers happen when there is not enough blood that reaches the legs or feet. whereas, venous ulcers happen when blood can’t flow properly back to the heart.
characteristics of differences between venous leg ulcers and arterial leg ulcers:
-cause
-location
-appearance
infectious skin conditions:
-cellulitus
-folliculitis
-furuncles
which of the following conditions is characterized by hyperproliferation of keratinocytes and dermal vascular changes?
Psoriasis
which of the stages of pressure injuries are full thickness?
-stage 3
-stage 4
-unstageable
