Study Notes

Protecting Normal Defence Mechanisms

Regular bathing eliminates transient microorganisms from the skin's surface, maintaining cleanliness.
Skin hydration and integrity are supported by proper lubrication.
Oral hygiene is crucial for removing saliva proteins that attract harmful microorganisms.
Flossing is effective in reducing tartar and plaque, essential for preventing infections.
Adequate fluid intake promotes normal urine formation, flushing microorganisms from the bladder and urethra.
In physically dependent patients, routine coughing and deep breathing prevent mucus accumulation in lower airways.
Immunization is vital for both children and adults to protect against infections.

Maintaining Healing Processes

Encourage the intake of a well-balanced diet rich in proteins, vitamins, carbohydrates, and fats to aid recovery.
Assist patients in improving appetite through various measures.
Promote comfort and adequate sleep, vital for daily energy replenishment.
Teach stress reduction techniques to enhance overall healing processes.

Isolation Guidelines

Significant risk of healthcare-associated infections (HAIs) exists, necessitating vigilant infection control practices.
Many organisms causing nosocomial infections originate from patients' own body substances.
CDC isolation guidelines utilize a two-tiered approach, initially established in 1996 and updated in 2007.
The Public Health Agency of Canada (PHAC) isolation guidelines cater to multiple care environments and share similarities with CDC guidelines.

Routine Practices

The first tier of isolation guidelines applies to all patients, irrespective of their infection status.
Routine practices include protective measures against exposure to blood, all body fluids except sweat, nonintact skin, and mucous membranes.
Use of gowns, gloves, masks, and eyewear is essential for barrier protection.
Strict hand hygiene, equipment cleaning, and proper disposal of contaminated materials are fundamental components.

Isolation Precautions

The second tier encompasses additional precautions for patients with highly transmissible pathogens, referred to as isolation precautions.
Isolation precautions are divided into three categories: airborne, droplet, and contact, depending on pathogen transmission routes.

Airborne Precautions

Specific measures are required for airborne pathogens, such as tuberculosis, which necessitate special masks and ventilated rooms.

General Isolation Precautions

Hand hygiene is crucial before entering or leaving an isolation room.
Contaminated supplies should be disposed of in accordance with the organism’s transmission mode.
Protective gear should be utilized based on the disease process and infection transmission methods.
Ensure protection for individuals when transporting patients outside isolation rooms.

Psychological Implications of Isolation Precautions

Isolation can lead to feelings of loneliness and disruption of social relationships, particularly harmful to children.
Altered body image and feelings of uncleanliness or rejection may arise from infection processes and isolation measures.
Active patient and family involvement in infection prevention enhances understanding and reduces feelings of isolation.

Protective Environment

Isolation rooms may use negative-pressure airflow to prevent the spread of infectious particles.
Positive-pressure airflow rooms cater to highly susceptible patients, such as organ transplant recipients.
A visible card outlining isolation precautions should be posted outside isolation rooms for awareness.
Essential facilities for hand hygiene must be available in isolation rooms, along with proper waste disposal systems to prevent microorganism transmission.

Isolation Room Practices

Specific articles, such as stethoscopes and thermometers, should be designated for isolation use and properly cleaned before use on other patients.
Care must be taken to prevent introducing infected articles into isolation areas, as this increases infection transmission risk.
