Hygiene
Learning Objectives
First Line of Defense Against Pathogens
Understand the body's role in protecting against pathogens.
Identify hygiene's impact on overall health.
Discuss factors affecting individual hygiene practices.
Describe procedures for delivering hygiene care in safe environments.
Scope of Practice Notes
Differences between RNs and PNs
Focus on PN practice considerations in callout boxes.
PN scope of practice varies by state:
Some states allow PNs to participate in care planning.
Others restrict PNs to assisting RNs with the care plan.
PNs must operate within their state's regulations for safe practice.
Introduction to Hygiene Concepts
Personal Hygiene Overview
Importance of personal hygiene practices:
Bathing (body and hair)
Hand hygiene
Nail care
Oral care
Foot care
Perineal care
Review of the body’s defenses against disease and infection.
Emphasis on hand hygiene as an infection prevention method.
Role of health promotion in hygiene practices.
Client Considerations
Privacy and Diversity
Impact of age, disability, cognitive impairment, and cultural practices on hygiene practices.
Nurse's Responsibilities
Assess client's hygiene habits.
Assist clients with activities of daily living (ADLs).
The Nursing Process
Steps in the Nursing Process
RNs: Assessment, Analysis, Planning, Implementation, Evaluation.
PNs: Data Collection, Planning, Implementation, Evaluation.
Body's Defenses Against Pathogens
Physical Barriers
Integumentary System:
Skin: Largest organ and first defense against pathogens.
Physical barrier against external threats.
Contains Langerhans cells to detect and kill pathogens.
Layers of Skin:
Epidermis: Outermost layer, vascular, made of squamous epithelial cells.
Dermis: Underlying connective tissue that provides strength and flexibility.
Hypodermis (Subcutaneous Layer): Insulates, cushions, stores fat.
Mucous Membranes
Line body passages open to the exterior and act as barriers against pathogens.
Secretion of Mucus: Entraps pathogens and small particles.
Cilia Function: Help expel trapped particles by pushing them to throat for coughing/sneezing.
Dental Health
Teeth Functions:
Chewing food, providing facial structure, assisting with speech.
Enamel: Hardest material protecting teeth from plaque and pathogens.
Dentin: Protects pulp (blood vessels and nerves); critical for tooth health; vulnerable to acid from bacteria leading to dental caries.
Nail Care
Structure of Nails: Protect distal ends of fingers/toes.
Cuticle: Epidermis that forms a barrier against infection.
Nail Maintenance:
Keep nails clean and dry.
Use gloves for dishwashing/harsh chemicals.
Trim nails straight across and care for cuticles properly.
Prevention measures against damage to the nail bed (avoid biting/picking).
Use acetone-free nail polish remover.
