Study Notes
Urinary Tract and Associated Conditions
- Bacteriuria is most commonly caused by urinary tract infections (UTIs).
- Bilirubinuria is associated with liver disease or conditions that cause increased bilirubin levels in the blood.
- Ketonuria is most likely caused by uncontrolled diabetes, fasting, or low-carbohydrate diets.
- Hematuria indicates the presence of blood in the urine, often detected through urine dipstick tests.
Urinalysis Indicators
- Leukocyte esterase indicates the presence of white blood cells in urine, suggesting a urinary tract infection.
- Proteinuria is commonly associated with kidney disease, diabetes, or hypertension.
Skin Lesions
- Keloid lesions are characterized by irregular, elevated scar tissue formed by excessive collagen growth during wound healing.
- Plaque lesions are flat-topped and larger than 2 cm in diameter.
- Petechiae are purplish lesions caused by free red blood cells in the skin that do not blanch on pressure; they may be nodular.
- A fissure is described as a crack in the skin that breaks through keratin.
- A vesicle is a blister smaller than 0.5 cm in diameter.
- Ulcer lesions involve loss of both epidermal and dermal tissues.
Hearing Loss Classifications
- Moderate hearing loss requires the use of hearing aids to hear normal conversation.
- Severe hearing loss allows individuals to hear sounds but not distinguish words without visual cues.
- Conductive hearing loss is most commonly caused by ear infections or blockages, such as earwax buildup.
- Sensorineural hearing loss is characterized by disorders affecting the inner ear, auditory nerve, or auditory pathways in the brain.
Vision Conditions
- Myopia, or nearsightedness, is caused by an eyeball that is too long or a cornea that is too steep, causing light to focus in front of the retina.
Communication Needs
- Profound hearing loss necessitates lip reading and sign language for effective communication.
Skin Cancer Types
- Melanoma is the most lethal type of skin cancer, often presenting as irregularly shaped moles or growths.
- Basal cell carcinoma is the most common form of skin cancer in the U.S. and rarely metastasizes.
- Squamous cell carcinoma may present as a non-healing ulcer or firm, red nodule.
Wound Healing Factors
- Ischemia and inadequate circulation predispose individuals to complications like infarction and gangrene.
- Neutrophil phagocytosis and collagen synthesis require proper nutrients and oxygen.
- Individuals with diminished WBC activity, such as older adults or those with certain conditions, are more susceptible to delayed wound healing and infections.
- Keloid formation during wound healing is marked by excessive growth of collagen, leading to firm, raised scars.
- Contractures result in inflexible shrinkage of wound tissue, commonly observed in burn victims.
- Factors affecting wound regeneration in infants versus adults include differences in metabolism, immune response, and tissue regeneration capacity.
