Signs and Symptoms - Patients experience intense itching, burning, and red skin in areas corresponding to the location of the topical irritation. - Edema may also occur in the area of sensitivity and symptoms can expand beyond the initial point of topical irritation. Treatment - The focus of treatment should be on identifying and removing the source of irritation. - Topical steroid application is commonly employed. Acute lesions should resolve with treatment once exposure to the external irritant has been removed.

Answer 40

* aka dermatitis * describe a group of disorders that cause chronic skin inflammation typically due to an immune system abnormality, allergic reaction or external irritant. Etiology - based on the particular form of the disorder. - Infants and children are at higher risk for eczema, however, many outgrow the condition with age. - The geriatric population is also at an increased risk for many forms of eczema. Signs and Symptoms - Red or brown-gray, itchy, lichenified skin plaques that may be exacerbated by some topical agents such as soaps and lotions. - younger: frequently experience oozing and crusting of the patchy areas of irritation. Treatment - Pharmacological interventions are variable ranging from topical or oral corticosteroids to oral antibiotics and antihistamines. Cold compresses and other modalities may assist with reducing the itching. Stress management techniques and avoidance of extreme temperatures should be employed to avoid potential exacerbations of the condition.

The skin cells accumulate in raised red patches on the surface of the skin. Etiology - Some patients have a genetic predisposition to plaque psoriasis. - Other factors may trigger psoriasis, such as injury to the skin, insufficient or excess sunlight, stress, excessive alcohol, HIV infection, smoking, and certain medications. Signs and Symptoms - The primary symptom is red raised blotches that typically present in a bilateral fashion for example over both knees or elbows. - These plaques can appear anywhere on the body and will tend to itch and flake. - Complications can include arthritis, pain, severe itching, secondary skin infections, and side effects secondary to pharmacological interventions. Treatment - primary goal to control the symptoms and prevent secondary infection. - Treatment varies widely from topical applications to systemic medications and phototherapy. - Plaque psoriasis is a life-long condition that can be effectively managed and controlled through the various stages and exacerbations.

Answer 45

* aka athlete's foot, * superficial fungal infection which causes epidermal thickening and a scaly skin appearance. * This fungus is opportunistic and will rapidly multiply in a warm and moist environment (e.g., between the toes). Etiology - Risk factors include wearing closed toe shoes that don't allow airflow, prolonged periods of moisture or wetness, excessive sweating, and possessing small nail or skin abrasions. This infection is contagious through direct contact or when making contact with a surface containing the tinea pedis infection. Signs and Symptoms - itching, redness, peeling skin between the toes, pain, odor, and in more severe cases breaks in skin continuity Treatment - Pharmacological intervention includes topical or oral antibiotics depending on the severity of symptoms. Tinea pedis may persist or recur and more long-term management may be required. Prevention includes thorough drying of the feet when bathing or swimming, wearing sandals around public pools or showers, changing socks frequently, proper hygiene, and avoiding shoe wear that creates a moist environment.

Answer 46

* varicella-zoster virus = children herpes zoster (shingles) = adults * can lie dormant for years and is highly contagious when it isn't dormant * Reactivation can occur when immune system has been weakened * S&S - blistered rash will appear on skin surface...but also on internal structures such as organ surfaces, mouth, and inner eye - itching or burning sensation (from attack on nerves) - painful blister rash - fever, body aches, chills, fatigue - blisters break open and drain * post-herpatic neuralgia due to scarring/destruction of nerve tissue is most common complication * Other complication: vision loss, balance deficits, or facial paralysis

Answer 67

arterial insufficiency The rubor of dependency test is used to assess for the presence of arterial insufficiency. The therapist elevates the patient’s leg with the patient in supine and notes the change in color of the lower extremity. A patient with arterial insufficiency will experience a rapid loss of the normal pinkish color of the skin, and it will take a prolonged period of time (i.e., greater than 30 seconds) for the color to return when the leg is returned to the starting position.

Answer 68

40 mm Hg Short stretch bandaging with high working pressure and low resting pressure help to facilitate the effects of the calf muscle pump during activity. Pressure of 40 mm Hg has been suggested as an acceptable guideline for patients with venous wounds.

Answer 69

compression dressings Compression dressings can further impede the circulation of a patient with an arterial insufficiency ulcer. There is no restriction to therapeutic exercises and gait training as long as pressure is not applied to the wound. Applying a hot pack to a more proximal segment will cause vasodilation and can help circulation at more distal segments

Answer 70

eczema Eczema is a term for a group of medical conditions that cause the skin to become inflamed or irritated. The condition is characterized by red or brown-gray, itchy, lichenified skin plaques that may be exacerbated by topical agents such as soaps and lotions. The most common type of eczema is known as atopic dermatitis or atopic eczema.

Answer 71

Answer 88

superficial The “rule of nines” is commonly utilized to assess the percentage of the body surface affected by partial thickness and full thickness burns

Answer 89

9 A child under one year has 9% taken from the lower extremities and added to the head and neck region. Each year of life, 1% is distributed back to the lower extremities until the age of nine when the head is considered to be the same proportion as an adult.

Answer 90

Head and neck According to the rule of nines, 36% of the body is made up of the trunk, 18% for each lower extremity, 9% for each upper extremity, 9% for the head and neck, and 1% for the genitals. When using this method for a child, the head and neck make up 18% of the body and the lower extremities each make up 14%.

Answer 91

36.0% The rule of nines is a method used to approximate the percentage of the body affected by a burn. The posterior trunk constitutes 18% of the total body surface area, the posterior portion of the left lower extremity constitutes 9%, and the entire left upper extremity constitutes 9% (4.5% for each side). 18%+9%+9% = 36%

Answer 92

27.0% According to the rule of nines, each arm is approximately 9% of the total body surface area and each leg is 18%. Therefore the bilateral, anterior surfaces of all four extremities would represent 27.0% of the total body surface area.

Answer 93

22.5% According to the rule of nines, the total surface area of the anterior portions of the bilateral lower extremities is 18% and the total surface area of the anterior portion of the right arm is 4.5%. The total surface area affected by the burn is equivalent to 22.5%.

Answer 94

* Severe edema is the most common occurrence. Severe burns cause protein loss from burned tissues and increased cell membrane permeability. Both factors contribute to alterations in tissue microcirculation resulting in significant edema formation in the interstitial spaces. - Hypertrophic or keloid scarring: associated with an imbalance of collagen lysis and synthesis during the healing process. During the remodeling phase (so not while in acute care) - Eschar refers to necrotic tissue which is typically brown or black in color and thickly textured. Eschar may be observed while a patient with significant burns is in an acute care environment. Though less likely than edema to be directly attributed to changes in cell permeability and microcirculation.

Answer 95

* Deep partial-thickness or full-thickness (burns typically taking greater than 14 days to heal) * 15-35mmHg to create an environment that facilitates the balance of collagen synthesis and lysis * worn for 22-23 hr/day for 2weeks and 2 months after wound closure or grafting. May continue up to 2 years. * Replace the garment every 3-6 months *
