Human Immunodeficiency virus

6 Stages of Infection Incubation

7 Stages of Infection Prodromal

8 Stages of Infection Full Stage Signs and symptoms Convalescent

9 Response to Infection Normal Flora Inflammatory Response

10 Response to Infection Immune Response

11 At Risk for Infection Integrity of skin and mucous membranes
Integrity of WBCs Vulnerable populations General Health Status Stress Level Indwelling devices

12 Common Infections Urinary Tract Infections (UTIs)

13 Common Infections Pulmonary Infections

14 Common Infections Skin Infections

15 PREVENTION Careful assessment Early detection AND action Immunizations
Assess for infections

16 Laboratory Data Normal values are listed. With infection, all are elevated WBCs (5,000-10,000 mm3) Neutrophils (60-70%)- acute infection Lymphocytes (20-40%)- chronic infection Eosinophils (1-4%)- allergic reaction Pathogen present in culture

17 Patient Outcomes Handwashing Hygiene Nutrition Immunizations
Signs of infection Symptoms of allergies

18 Asepsis Activities to prevent spread of infection
Medical asepsis- clean technique Surgical asepsis- sterile technique

19 Medical Asepsis Hand hygiene Carry linens away from your body
No linens on floor Cover mouth when sneezing Do not raise dust Do not shake linens Clean to dirty Transmission precautioins
