Questions and Answers

What are some examples of secondary skin lesions?

Crusts, keloids, scars, and cysts are examples of secondary skin lesions.

How can skin moisture be assessed?

Skin moisture can be assessed by palpating the skin for dryness or excessive moisture.

What does skin turgor indicate about the body's hydration status?

Skin turgor indicates the fullness or elasticity of the skin, reflecting hydration status.

Study Notes

Nail and Skin Assessment

Nail Bed Color Normalcy: Nail beds should appear highly vascular and pink; in dark-skinned individuals, they may be brown or black.
Nail Bed Color Deviations: Bluish or purplish tinges indicate possible issues; pale coloration is also a warning sign.

Inspection of Surrounding Tissues

Normal Surrounding Tissues: Epidermis should be intact without any signs of damage.
Deviations: Presence of hangnails or paronychia, indicating ingrown nails, and inflammation in surrounding tissues suggests potential health problems.

Blanch Test/Capillary Refill Test

Normal Results: Color should return promptly to pink or usual color in less than 2-4 seconds after pressure is released.
Deviations: Delayed return of color longer than 4 seconds is abnormal, indicating circulation issues.

Hair Assessments

Hair Abnormalities: Can arise from certain medications or endocrine disorders, leading to various changes.
Hirsutism: Presence of excessive body hair, typically considered a condition of abnormal hair growth.
Alopecia: More common in men; can result from aging, infections, chemical exposure, trauma, and specific drugs or disorders.

Normal and Abnormal Hair Characteristics

Normal Hair: Evenly distributed, thick, silky, and resilient in texture.
Abnormal Hair: Patches of hair loss or alopecia, brittle hair due to poor nutrition, or excessively oily/dry hair conditions.

Scalp Inspection

Normal Scalp: No infection or infestation present.
Deviations: Signs of flaking, sores, or presence of lice/nits indicate unhealthy scalp conditions.

Skin Assessment

Skin Moisture Evaluation: Skin should be moist; excessively dry skin is a deviation from normal.
Temperature Palpation: Normal temperatures indicate health, while generalized or localized hyperthermia/hypothermia suggest potential issues.

Skin Turgor Measurement

Normal Turgor: Skin should spring back to its original state within 3 seconds when pinched, indicating good hydration.
Deviations: Skin that remains pinched or moves back slowly suggests dehydration.

Nail Assessment Techniques

Nail Plate Inspection: Should appear colorless with a convex curve.
Normal Nail Angles: Typically at 160 degrees; clubbed nails (>180 degrees) may indicate chronic tissue hypoxia.

Secondary Skin Lesions

Types of Lesions: Includes crusts, keloids, scars, and cysts, which can provide insights into underlying health conditions.
