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.
