Study Notes

Skin Health

Xerosis often appears as dry, flaky, and itchy skin.
Xanthelasma is associated with yellowish waxy deposits on the eyelids.
Telangiectasias indicate dilated blood vessels, often seen in conditions like rosacea or scleroderma.
Cyanosis (blue discoloration) may indicate possible chronic heart or lung disease.
Cutis laxa is characterized by wrinkles, sags, and overlapping skin folds.
The epidermis acts as the outermost layer of skin, protecting against external factors and regulating moisture.
The tibial nerve innervates the medial and lateral surface of the sole.
The dermis provides strength, elasticity, and contains glands, hair follicles, and blood vessels.
Plantar flexion of the toes occurs during actions like walking or standing on tiptoes.
Cellulitis and infections primarily occur in the dermis and subcutaneous layers.
The median nerve stimulates the skin area between the thumb and second finger.
The hypodermis is primarily composed of fat, providing insulation, cushioning, and energy storage.
Abduction of the little finger involves the patient touching the little finger away from the other fingers.
Muscle atrophy is a structural change occurring in muscles as they age, causing decreased muscle mass and strength.
Lordosis is a condition characterized by an increased forward curvature of the lumbar spine.
Loss of collagen in connective tissue results in decreased elasticity, wrinkles, and joint laxity.
Paresthesias in elderly patients are frequently caused by compression of nerves due to aging and changes in posture.
Joint pain and stiffness are typical findings associated with osteoarthritis.
A shuffling gait may indicate lower motor neuron disease.
Ultrasound imaging is the best tool for visualizing soft tissue changes.
Ligaments become less flexible and weaker with age, leading to increased joint instability.
Temperature is not typically included in neurovascular status assessment.
Crepitus in joints suggests roughening of joint surfaces or inflammation.
Kyphosis is indicated by an increased forward curvature of the thoracic spine.
Cartilage thinning and degeneration is the most significant change observed in cartilage with aging.
Jaundice refers to the yellowish discoloration of the skin, primarily in sclerae, due to increased bilirubin levels.
Vitiligo describes patchy, milky white spots often symmetric bilaterally.
A nodule is an elevated, palpable, solid mass extending deeper into the dermis than a papule.
Cyanosis is synonymous with an increased amount of unoxygenated hemoglobin in the blood.
Hemosiderosis is characterized by hemosiderin buildup in the skin, causing reddish-brown discoloration.
A plaque is an elevated mass with irregular and transient borders, often varying in size and color.
A patch is a macule with a diameter greater than 1 cm and may have an irregular shape.
A vesicle is a circumscribed elevated mass containing serous fluid, less than 0.5 cm in size.
Edema in superficial venous disease may be difficult to detect due to other changes.
Jaundice indicates a significant increase in serum bilirubin levels, commonly seen in liver dysfunction.
Osmolality measures the concentration of solutes in a solution, while osmolarity measures the number of osmotically active particles per liter of solution.
Tonicity describes the ability of a solution to cause water to move across a semipermeable membrane.
Decreased urine output and increased heart rate are physiological changes likely indicating fluid volume deficit.
Hypervolemia is characterized by isotonic expansion of the extracellular fluid.
A higher BUN level compared to serum creatinine may indicate dehydration or renal insufficiency.
Hypothyroidism is not typically associated with fluid volume deficit.
The sodium-potassium pump actively transports sodium out of the cell and potassium into the cell, maintaining cell volume and membrane potential.
Thirst is a potential indicator of dehydration.

Fluid and Electrolytes

Osmolality measures the concentration of solutes in a solution.
Osmolarity measures the number of osmotically active particles per liter of solution.
Tonicity describes the ability of a solution to cause water to move across a semipermeable membrane.
Dehydration is characterized by fluid loss greater than fluid intake, leading to a decrease in body water.
Hypervolemia is characterized by fluid overload, leading to increased blood volume.
Blood Urea Nitrogen (BUN): A higher BUN level compared to serum creatinine suggests dehydration or renal insufficiency.
Sodium-potassium pump helps maintain cell volume and membrane potential by actively transporting sodium out of the cell and potassium into the cell.
