๐ฉ- Integumentary & Respiratory Test Flashcards
Uncomplicated skin and soft tissue infection
Respond to antibiotic therapy alone or surgical drainage with or without antibiotic therapy
Ex: cellulitis, folliculitis, impetigo, boils/abscess
Caused by staph aureus and strep pyogenes
3 main parts of the skin
Epidermis (outer layer) - primary function is protection
Dermis (inner layer) - provide strength, support, blood and nutrients to epidermis
Subcutaneous tissue - anchor dermis, provide insulation and protection
Complicated skin and soft tissue infections
Invasion of deeper tissues and require debridement
Usually cause by polymicrobial
Pathophysiology of non-necrotizing cellulitis
Microorganisms find entry through skin breaches
Pathophysiology of herpes
Occur on skin, mucous membranes, central nervous system and genital tract
Dermatophytes
Aerobic fungi that infect the stratum corneum (top, dead layer of skin) and survive on keratin

Pathophysiology of fungal infections
- superficial cutaneous fungal infections
- donโt spread beyond the epidermis
Can be found living in soil, on animals and humans. Feed on dead keratin of the skin hair and nails

Potassium hydroxide (KOH) microscopy
Scrape skin from area and view under microscope โ presence of hyphae confirm diagnosis
(Fungal infection)

Pathophysiology of psoriasis
Immune disorder that causes chronic inflammation of the skin characterized by thick, raised red patches covered with silvery flaking scales

Psoriasis and weather
Patients do better in warmer climates
UV radiation kills rapidly proliferating skin cells

Laceration
Break in the skin caused by penetration of a sharp object

Abrasion
Occurs as a result of friction and shear from external forces , are usually minor injuries involving only the epidermis

Excoriation
A superficial abrasion
Usually seen in disorders that cause pruritus (itching) such as insect bites, scabies, chicken pox
Also used to describe the loss of epithelium in response to prolonged exposure to urine and feces in an individual who is incontinent

Friction blisters
Friction is a force that is applied parallel to a surface resulting in rubbing motion

Traumatic wounds usually caused by minor trauma that primarily affect older adults

Normal range of pH for respiratory
7.35 - 7.45
Normal range of PaCO2
35 - 45 mmHg
Normal range of PaO2
80 - 100 mmHg
Normal range of HCO3
22 - 26 mEq/L
Capnography
Continuously monitors the PaCO2 in the airway during inhalation and exhalation and provides a written tracing
Capnometry
Color change to blue at end of ET tube
Nasal cannula
24-44% FiO2
1-6 L/min
Used in chronic lung disease or long term use
(Low flow o2 delivery)
Simple face mask
40-60% FiO2
5-10 L/min
Used short term in emergency or transport
(Low flow o2 delivery)
