Skin |
Largest Organ in the body. First line of defense. Nursing problems include: Infection, fluid & electrolyte imbalance, nutritional deficits, and tissue alterations. |
|
Epidermis |
This layer is made of skin cells at the end of their life-cycle. These cells provide protection from injury and a barrier to keep infectious organisms at bay. Think of this layer as the mulch covering the flowerbed. The epidermis holds in fluid and protects raw nerve cells from too much stimulation. |
|
Dermis |
The top soil. This layer contains capillaries that feed the cells with nutrient-rich blood. Just like top soil, most things grow here - including hair follicles, nerve cells, and sweat glands. If damaged, the dermis will weep serous fluid and swell. |
|
Subcutaneous |
This layer is also known as the hypodermis, and it is technically not officially skin, but rather attaches the skin to everything beneath. It also contains a layer of fat. Some of use have more fat than others, but this layer is always present in some form. In the flower bed, this is the layer of sand foundation that allows for drainage. Indeed, blood vessels in the subcutaneous layer feed and drain the capillaries of the dermis. |
|
5 Major Functions of the skin |
Protection against disease (It acts as a first defense against disease causing particles, due to the fact most can get through unopened skin). Sensory response (specialized nerve cells sense and relay info to the brain). Formation of Vitamin D (formed by ultraviolet light in fat molecules in your epidermis). Maintaining body temperature (blood vessels in the skin can help to hod or release heat maintaining a constant temperature) Waste exchange (sweat glands in the skin release waste in the sweat) |
|
Interactions with other body systems |
Putting the data together: why we do skin assessments! Respiratory system, cardiovascular system, gastrointestinal system, urinary system, neurological system, endocrine system, lymphatic/immune system. |
|
Cyanosis |
Central and Peripheral Cyanosis. Not getting enough oxygen to the nail bed. You can check this to see how well the oxygen is getting to the extremities. |
|
Cardiovascular |
Altered Perfusion. Poor circulation. The dermis is not getting the blood supply that it needs and cannot feed the tissue. You can get an arterial ulcer. The toes can become necrotic. The tissue is dying and if not removed, gangrene can move in. |
|
Xanthelasma |
A localized cholesterol deposit beneath the skin and expecially beneath the eyelids - is a common manifestation of hypercholesterolemia. Lipid deposits that are not being excreted by the liver. |
|
Spider angiomas (Spider nevi) |
Collections of dilated blood vessels near the surface of the skin. They appear as slightly raised, small, reddish spots from which fine lines radiate outward, giving them a spider-like appearance. Can occur anywhere. Blood vessels are dilated because of pressure. |
|
The Urinary System |
Related to decrease ability to excrete toxins |
|
Neurological System |
Changes related to autonomic nervous system. There are changes in: Touch, temperature, pressure, pain |
|
ANS |
Controls the skin's blood vessels and glades results in changes in moisture and temperature |
|
Endocrine system |
Diabetes- ulcerations. |
|
Hypo or hyperthyroidism |
Hypo- dryness (hair becomes brittle) Hyper- increased moisture (oily hair) |
|
Adrenal disease |
Adrenal gland produces stress hormones. Darkening of the skin. |
|
Breakout- Diabetes and Skin Related Changes |
Diabetes can affect every part of the body, including the skin. Skin problems are sometimes the first sign that a person has diabetes. Luckily, most skin conditions can be prevented or easily treated if caught early. Some of the problems are skin conditions anyone can have, but people with diabetes get more easily. These include bacterial infections, fungal infections and itching. Other skin problems happen mostly or only to people with diabetes. These include diabetic dermopathy disease of the skinX, necrobiosis lipidica diabeticoruma skin condition usually on the lower part of the legs. Lesions can be small or extend over a large area. They are usually raised, yellow, and waxy in appearance and often have a purple border. X, diabetic blisters, and eruptive xanthomatosis. |
|
Diabetes: Bacterial infections |
Styes (infections of the glands of the eyelid) Bois Folliculitis (infections of the hair follicles) Carbuncles (deep infections of the skin and the tissue underneath. Infections around the nails, inflamed tissues that are usually hot, swollen, red, and painful. Several different organisms can cause infection, the most common being Staphylococcus bacteria. |
|
Diabetes: Fungal Infections |
The culprit in fungal infections of people with diabetes is often Candida albicans. This yeast-like fungus can create itchy rashes of mosit, red areas surrounded by tiny blister and scaled. The infections often occur in war, mosit folds of the skin. Problem areas are under the breasts, aound the nails, between fingers and toes, in the corners of the mouth, under the foreskin, and in the armpits and groin. Common fungal infections include: jock itch, athlete's foot, ringworm (a ring-shaped itchy patch), and vaginal infection that causes itching. |
|
Diabetes: Itching |
Localized Itching is often caused by diabetes. It can be caused by a yeast infection, dry skin, or poor circulation. When poor circulation, the flow of blood through the body's blood vessels and Heart. X is the cause of itching, the itchies areas may be the lower parts of the legs. You may be able to treat itching yourself. Limit how oftern you bathe, particularly when the humidity is low. Use mild soap with moisturizer and apply skin cream after bathing. |
|
Velvet Plaques |
Velvety plaques in the neck and/or armpit suggest diabetes. This condition- acanthosis nigricans- could be benign or be caused by obesity. But, it is very often a sign of diabetes. In rare cases, acanthosis nigricans occurring in other places, like the hands or lips and they may indicate an internal cancer. |
|
Acanthosis Nigricans |
A condition in which tan or brown raised areas appear on the sides of the neck, armpits, and groin. They can also occur on the hands, elbows, and knees. |
|
Diabetic Dermopathy |
Known as shin spots which are caused as result of changes to the blood vessels which supply the skin. Dermopthy look like shiny oval or round lesions on the skin which is thin. Found on lower front parts of the lower leg. Diabetes can cause changes in the small blood vesselstubes that carry blood to and from all parts of the body. The 3 main types of blood vessels are arteris, veins, and capillaries. X. These changes can cause skin problems called diabetic dermopathy. Dermopathy often looks like light brown, scaly patches. These patches may be oval or circular. Some people mistake them for age spots. This disorder most often occurs on the front of both legs. |
|
Necrobiosis Lipoidica Diabeticorum (NLD) |
Changes in collagen and fat content beneath. The skin cause this problem. Skin becomes reddened and thinned. Problems are found on parts of the lower legs and can ulcerate. Often is painful and itchy. Disease that may be caused by changes in the blood vessels is necrobiosis lipoidica diabetucorum (NLD). NLD causes spots similar to diabetic dermopathy, but they are fewer, larger, and deeper. NLD often starts as a dull, red, raised area. After a while, it looks like a shiny scar with a violet border. The blood vessels under the skin may become easier to see. Sometime NLD is itchy and painful. Sometimes the spots crack open. |
|
Digital Sclerosis |
Condition where skin on the fingers, toes, and hands turn waxy, thick, and tight. A stiffness of the joints of the finger can also occur. Moisturizers and lotions can help with softening the skin. |
|
Immune System |
Skin is a protective barrier, therefore, the more breaks in the skin = increase risk of infection. Think about the number of access sites patients usually has. Allergic Reaction: Psoriasis, Dermitis, Lupus erythematosus. |

|
Diaphragmatic excursion |
The movement of the thoracic diaphragm during breathing. Normal diaphragmatic excursion should be 3-5 cm, but can be increased in well-conditioned persons to 7-8 cm. This measures the contraction of the diaphragm. It is performed by asking the patient to exhale and hold it. The provider then percusses down their back in the intercostal margins (bone will be dull) starting below the scapula, until sounds change from resonanat to dull (lungs are resonant, solid organs should be dull). That is where the provider marks the spot. Then the patient takes a deep breath in and holds it a s the provider percusses down again, marking the spot where the sound changes from resonant to dull again. The the provider will measure the distance between the two spots. Repeat on the other side, is usually higher up on the right side. If it is less than 3-5 cm, the patient may have a pneumonia or a pneumothorx in which a chest x-ray is diagnostic for either. |
