    Now that we have reviewed the anatomy of the integumentary system and common integumentary conditions, let’s review the components of an integumentary assessment. The standard for documentation of skin assessment is within 24 hours of admission to inpatient care. Skin assessment should also be ongoing in inpatient and long-term care.[1]

    A routine integumentary assessment by a registered nurse in an inpatient care setting typically includes inspecting overall skin color, inspecting for skin lesions and wounds, and palpating extremities for edema, temperature, and capillary refill.[2]

    Subjective Assessment

    Begin the assessment by asking focused interview questions regarding the integumentary system. Itching is the most frequent complaint related to the integumentary system. See Table \(\PageIndex{1}\) for sample interview questions.

    Table \(\PageIndex{1}\): Focused Interview Questions for the Integumentary System
    Questions Follow-up
    Are you currently experiencing any skin symptoms such as itching, rashes, or an unusual mole, lump, bump, or nodule?[3] Use the PQRSTU method to gain additional information about current symptoms. Read more about the PQRSTU method in the “Health History” chapter.
    Have you ever been diagnosed with a condition such as acne, eczema, skin cancer, pressure injuries, jaundice, edema, or lymphedema? Please describe.
    Are you currently using any prescription or over-the-counter medications, creams, vitamins, or supplements to treat a skin, hair, or nail condition? Please describe.

    Objective Assessment

    There are five key areas to note during a focused integumentary assessment: color, skin temperature, moisture level, skin turgor, and any lesions or skin breakdown. Certain body areas require particular observation because they are more prone to pressure injuries, such as bony prominences, skin folds, perineum, between digits of the hands and feet, and under any medical device that can be removed during routine daily care.[4]

    Inspection

    Color

    Inspect the color of the patient’s skin and compare findings to what is expected for their skin tone. Note a change in color such as pallor (paleness), cyanosis (blueness), jaundice (yellowness), or erythema (redness). Note if there is any bruising (ecchymosis) present.

    Scalp

    If the patient reports itching of the scalp, inspect the scalp for lice and/or nits.

    Lesions and Skin Breakdown

    Note any lesions, skin breakdown, or unusual findings, such as rashes, petechiae, unusual moles, or burns. Be aware that unusual patterns of bruising or burns can be signs of abuse that warrant further investigation and reporting according to agency policy and state regulations.

    Auscultation

    Auscultation does not occur during a focused integumentary exam.

    Palpation

    Palpation of the skin includes assessing temperature, moisture, texture, skin turgor, capillary refill, and edema. If erythema or rashes are present, it is helpful to apply pressure with a gloved finger to further assess for blanching (whitening with pressure).

    Temperature, Moisture, and Texture

    Fever, decreased perfusion of the extremities, and local inflammation in tissues can cause changes in skin temperature. For example, a fever can cause a patient’s skin to feel warm and sweaty (diaphoretic). Decreased perfusion of the extremities can cause the patient’s hands and feet to feel cool, whereas local tissue infection or inflammation can make the localized area feel warmer than the surrounding skin. Research has shown that experienced practitioners can palpate skin temperature accurately and detect differences as small as 1 to 2 degrees Celsius. For accurate palpation of skin temperature, do not hold anything warm or cold in your hands for several minutes prior to palpation. Use the palmar surface of your dominant hand to assess temperature.[5] While assessing skin temperature, also assess if the skin feels dry or moist and the texture of the skin. Skin that appears or feels sweaty is referred to as being diaphoretic.

    Capillary Refill

    The capillary refill test is a test done on the nail beds to monitor perfusion, the amount of blood flow to tissue. Pressure is applied to a fingernail or toenail until it turns white, indicating that the blood has been forced from the tissue under the nail. This whiteness is called blanching. Once the tissue has blanched, remove pressure. Capillary refill is defined as the time it takes for color to return to the tissue after pressure has been removed that caused blanching. If there is sufficient blood flow to the area, a pink color should return within 2 seconds after the pressure is removed. [6]

    Note

    Skin Turgor

    Skin turgor may be included when assessing a patient’s hydration status, but research has shown it is not a good indicator. Skin turgor is the skin’s elasticity. Its ability to change shape and return to normal may be decreased when the patient is dehydrated. To check for skin turgor, gently grasp skin on the patient’s lower arm between two fingers so that it is tented upwards, and then release. Skin with normal turgor snaps rapidly back to its normal position, but skin with poor turgor takes additional time to return to its normal position.[8] Skin turgor is not a reliable method to assess for dehydration in older adults because they have decreased skin elasticity, so other assessments for dehydration should be included.[9]

    Edema

    If edema is present on inspection, palpate the area to determine if the edema is pitting or nonpitting. Press on the skin to assess for indentation, ideally over a bony structure, such as the tibia. If no indentation occurs, it is referred to as nonpitting edema. If indentation occurs, it is referred to as pitting edema. See Figure \(\PageIndex{1}\)[10] for an image demonstrating pitting edema. If pitting edema is present, document the depth of the indention and how long it takes for the skin to rebound back to its original position. The indentation and time required to rebound to the original position are graded on a scale from 1 to 4, where 1+ indicates a barely detectable depression with immediate rebound, and 4+ indicates a deep depression with a time lapse of over 20 seconds required to rebound. See Figure \(\PageIndex{2}\)[11] for an illustration of grading edema.

    Life Span Considerations

    Older Adults

    Older adults have several changes associated with aging that are apparent during assessment of the integumentary system. They often have cardiac and circulatory system conditions that cause decreased perfusion, resulting in cool hands and feet. They have decreased elasticity and fragile skin that often tears more easily. The blood vessels of the dermis become more fragile, leading to bruising and bleeding under the skin. The subcutaneous fat layer thins, so it has less insulation and padding and reduced ability to maintain body temperature. Growths such as skin tags, rough patches (keratoses), skin cancers, and other lesions are more common. Older adults may also be less able to sense touch, pressure, vibration, heat, and cold.[12]

    When completing an integumentary assessment it is important to distinguish between expected and unexpected assessment findings. Please review Table \(\PageIndex{2}\) to review common expected and unexpected integumentary findings.
