1INTEGUMENTARY SYSTEM PN 124 BACTERIAL AND FUNGAL INFECTIONS
2ObjectivesDiscuss s/s of 8 infectious disorders of the skin; bacterial and fungalDefine the nursing management of the client with infectious disorders of the skinDiscuss common diagnostic tests used as diagnostic tools for integumentary disorders
3CELLULITIS, Bacterial infection Etiology/Pathophysiology-infection is potentially serious.-not contagious-can be spread by direct contact with anopen area from a person that has aninfection.-causes in adults: group A streptococciand Staphylococcus aureus.
4CELLULITIS -Hemophilus influenzae type B is more common in children. -increase the risk for cellulitis:-venous insufficiency or stasis-diabetes mellitus-lymph edema-surgery-malnutrition-substance abuse-treatment with steroids or cancer chemotherapy
5RISKS FOR CELLULITIS - presence of another infection - compromised immune function due tohuman immunodeficiency virus (HIV)- autoimmune diseases, such as lupuserythematosus
6CELLULITIS -Develops as an edematous, erythematous area of skin -hot and tender-bacteria enters through a break in theskin-can be from a cut, scratch, insect bite, etc-common areas are the lower extremities.-usually is a superficial infection-may spread and become life-threatening
11CELLULITIS -s/s are caused by the bacteria, and the body’s attempts to stop the infection.-skin appears pitted, like an orange peel.-area of redness spreads and small redspots appear-vesicles may form and burst
12CELLULITIS-nearby lymph nodes may become enlarged and tender. (lymphadenitis)-edema secondary to the infected area occludes the lymphatic vessels in the skin.-most patients only feel mildly ill,- but some have fever, chills, headache,tachycardia, confusion, hypotension.
13ERYSIPELAS A specific acute, inflammatory disease -caused by a beta- hemolytic streptococci-characterized by hot, red, edematousand sharply defined eruptions
15ASSESSMENT SUBJECTIVE: - fatigue - tenderness - pain - limited movement of the involvedextremity, - feeling of general malaise.
16ASSESSMENT OBJECTIVE: -Inspection of the skin - erythema - edema - areas that are warm to the touch.-Vesicles may be present.-Elevated temperature.-Tachycardia-Leukocytosis.
17DIAGNOSTIC TESTS Cultures - identifies the causative bacteria -from the blood, purulent exudate, ortissue specimens-Gram stain-determines the appropriate antibiotictherapy.Complete blood count (CBC).Inspection of the area
18DIAGNOSTIC TESTS -Tests done to differentiate cellulitis from deep vein thrombosis.- ( they both have similar s/s)- X-ray, ultrasound, computed tomographyor magnetic resonance imaging (MRI)- determines the extent of inflammation-identifies abscess formations
19MEDICAL MANAGEMENT Antibiotic treatment - effect against streptococci andstaphylococci- 10 day course-can be either oral or IV depending onseverity
20Nursing DiagnosisDeficient knowledge, related to the cause and the spread of the disease.Pain related to edema
21NURSING INTERVENTIONS -Treat s/s and to prevent the spread of theinfection.-Administer the antibiotic-Assess pain; administer an analgesic ifnecessary-Warm, moist dressings applied to the affectedarea may relieve discomfort.-Monitor fluid intake and nutritional status.
22NURSING INTERVENTIONS -Keep the affected part immobile - helps reduce the edema -Stress the importance of taking the entire prescription of antibiotics. -Monitor for secondary diseases, such as yeast infections
23PROGNOSIS Cure is possible with 7-10 days of treatment. Cellulitis may be more severe in people with chronic diseases and those who are susceptible to infection, such as the immunocompromised.Complications: sepsis, meningitis, and lymphangitis.
24Bacterial Disorders of the Skin Impetigo contagiosaEtiology/pathophysiologyStaphylococcus aureus or streptococci, or a mixed bacterial invasion of the skin.Common in children.
25IMPETIGO Clinical manifestations/assessment Lesions begin as macules - develop into pustule vesicles.Pustules rupture-form honey-colored exudate.-under the exudate is smooth, red skin.Affects exposed areas-face, hands, arms, and legs.Highly contagious—-direct or indirect contactLow-grade fever; leukocytosist
26Nursing assessment SUBJECTIVE DATA: -Ask about pruritis. -Ask about pain and malaise.-Ask about the spreading of thedisease to different body parts-Ask about other diseases present.
27IMPETIGO OBJECTIVE DATA: -Focal erythema. -Pruritic areas. -Honey-colored crust over dried lesions.-Smooth, red skin under the crust.-Low-grade fever.-Leukocytosis.-Positive culture for streptococcus orstaphylococcus aureus.-Purulent exudate.
28Diagnostic Tests Medical management -Culture of exudate from lesions -Antiseptic soap (Betadine of Hibiclens)to remove crusted exudate and cleanarea-Topical cream, ointment or lotion-Antibiotics, oral or IV (Penicillin)-Keep area clean and dry
29Folliculitis, furuncles, carbuncles, and felons Etiology/pathophysiologyFolliculitisInfected hair follicle (generally from Staphylococcus aureus).Furuncle (boil)Infection deep in hair follicle; involves surrounding tissue.CarbuncleCluster of furuncles.FelonsInfected soft tissue under and around an area.
30Folliculitis, furuncles, carbuncles, and felons Clinical manifestations/assessment-Pustule-Edema-Erythema-Pain-Pruritus-Shiny, point upCarbuncle-the center will turn yellow.
33ASSESSMENT SUBJECTIVE: -patient’s symptoms. -family history of diabetes mellitus.-wearing of improperly fitting clothes.
34ASSESSMENT OBJECTIVE: -erythema an -edema of the involved area. -often overweight-may use poor body hygiene practices.
35NURSING DIAGNOSESImpaired skin integrity, related to exudate from woundPain, related to edema
36DIAGNOSTIC TESTS Diagnostic tests Physical exam Culture of drainage Health history
37MEDICAL MANAGEMENT -Goal - prevent the spread of the infection. -Patients in the hospital are isolated- using wound and secretion precautions.
38Folliculitis, furuncles carbuncles and felons Medical management/nursing interventions-Warm soaks 2-3 times per day-promote suppuration-Once the lesion ruptures,-hot soaks are discontinued-prevents damage to the surrounding skinand the spread of infection.
39-medical asepsis.-topical antibiotic cream or ointment-surgical incision and drainage-immobilize affected area to prevent pain-elevate affected area to decrease theedema.
40PATIENT TEACHING -Patient should not touch the exudate. -Meticulous hand washing-BEFORE and AFTER contact with thelesions.-Hygiene practices should bedemonstrated and return demonstrationsdone by the family and the patient.
41-Whole family needs individual toilet items and bath linens-bacteriostatic soap and shampoo.-Demonstrate proper disposal ofcontaminated articles.
48TINEA CRURIS-Jock itch.-Found in the groin area.
49TINEA PEDIS -Most common of all fungal infections. -Athlete’s foot. -Between the toes ofpeople whose feetperspire heavily.-Contaminated swimmingpools and publicbathroom facilities
50SIGNS AND SYMPTOMS TINEA CAPITIS: -erythematous. -round lesion with pustules around theedges-temporary alopecia-infected hairs will turn blue-green under aWood’s light.
51SIGNS AND SYMPTOMS -TINEA CORPORIS: -flat lesions that are clear in the center with erythematous borders.-scaliness-pruritis is severe.
52SIGNS AND SYMPTOMS 3. TINEA CRURIS: Has brownish-red lesions that migrate out from the groin area.Pruritis is a symptom.Scratching is done to relieve the itching. As a result, skin excoriation is present.
53SIGNS AND SYMPTOMS TINEA PEDIS: This fungal infection produces more skin maceration than the others.Fissures and vesicles are commonly seen around and below the toes, with occasional discoloration of the infected area.
54ASSESSMENT SUBJECTIVE DATA: -extreme itching -tenderness from excoriation of the area
55ASSESSMENT OBJECTIVE DATA: -TINEA CAPITIS: -inspection -round, scaled lesion-purulent vesicles around the edges ofthe scalp.-erythemaalopecia to the surrounding area
56ASSESSMENT OBJECTIVE DATA: -TINEA CORPORIS: -flat lesions with clear centers and red borderson non-hairy body parts.
57ASSESSMENT TINEA CRURIS: -groin-brown to red lesions that spread outward.-skin excoriation from scratching.TINEA PEDIS:-fissures between the toes and soft skin.-vesicular lesions-thick toenails.
58DIAGNOSTIC TESTS -visual inspection. -Wood’s lamp-diagnose tinea capitis.-thorough health history
59MEDICAL MANAGEMENT-topical or oral antifungal agents.-Griseofulvin (oral)-topical drugs do not penetrate the hairbulb-antifungal soaps and shampoos
60Antifungal agents-Tinactin, Lotrimin, or Desenex -2-6 weeks.See AHN p. 77. for a list of drugs that are used.
61NURSING DIAGNOSESImpaired skin integrity, related to increased moisture and pruritis
62NURSING INTERVENTIONS -Protect the involved area from trauma and irritation-keep the area clean and dry.-Apply medications-warm compresses-Tinea pedis-warm soaks (usually Burrow’s solution)-topical antifungal agents.
63NURSING INTERVENTIONS -Clean and dry the feet thoroughly-completely dry the toes-Wear sandal-like shoes/go barefoot-prevents moisture in the toes-Footwear needs to be of an absorbent material-socks, stockings, etc.-Wear loose-fitting clothing.
64TEACHING1. Teach proper skin care and comfort measures to relieve itching.2. The nurse needs to review the meds. and procedures to be done at home by the pt.3. The nurse should remind the pt. that it may take months for fungal disorders to be cured.4. Clarify any misconceptions about athlete’s foot.5. Teach the pt. the process of this disease.
67PARASITIC DISEASES OF THE SKIN PediculosisEtiology/pathophysiology-Lice infestation
68Pediculosis Three types of lice -Head lice (capitis) -Attaches to the hair shaft and lays eggs-Body lice (corpis)-Found around the neck, waist, and thighs-Found in seams of clothing-Pubic lice (crabs)-Looks like a crab with pinchers-Found in pubic areas
69Pediculosis Clinical manifestations/assessment Diagnostic tests -Nits and/or lice on involved area-Pinpoint raised, red macules-Pinpoint hemorrhages-Severe pruritis-ExcoriationDiagnostic tests-Physical exam
70Pediculosis Medical management/nursing intervention -Lindane (Kwell); Pyrethrins (RID)-Cool compresses-Corticosteroid ointment-Assess all contacts-Wash linens and clothes in hot water-Properly clean furniture or non-washablematerials
72Scabies Etiology/Pathophysiology -Sarcoptes scabiei (itch mite) -Mites lay eggs under the skin-Transmitted by prolonged contact withinfected area
73Scabies Clinical manifestations/assessment -Wavy, brown, threadlike lines on thebody-Pruritis-Excoriation
74Scabies Diagnostic tests -Microscopic examination of infected skin -Scratch testMedical management/nursing interventions-Lindane (Kwell), Pyrethrins (RID), Crotamiton(Eurax), 4-8% solution of sulfur in petrolatum-Treat all family members-Wash linens and clothing in hot water
