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.
