Study Notes

Medical Asepsis and Hand Hygiene

Medical asepsis refers to practices aimed at reducing the number of pathogens to prevent infection.
Effective hand hygiene is critical in healthcare settings for preventing transmission of infections.
Alcohol-based hand scrub must contain at least 60% alcohol to be effective against pathogens.

Personal Protective Equipment (PPE)

PPE is essential for protecting healthcare workers and patients during procedures.
When removing PPE, follow the correct sequence to prevent contamination: gloves, gown, face shield or goggles, and mask.
For observing sterile procedures in the operating room, a nurse would don gloves, gown, mask, and goggles.

Standard Precautions and Needle Safety

Standard precautions include hand hygiene, use of PPE, and proper disposal of sharps.
To prevent accidental needlestick injuries, nurses should use safety-engineered devices and avoid recapping needles.
Educating patients on standard precautions is crucial for infection control.

Infection Control Measures

Nurses can suggest frequent handwashing and masking during influenza season to control respiratory infections transmission.
Patients with influenza require droplet precautions upon admission.
Community engagement, such as vaccination campaigns, can help slow infection transmission in the population.

Immunization and Home Care Interventions

The CDC is a reliable source for updated adult immunization schedules.
Home care interventions, such as proper disposal of waste and cleaning surfaces, help reduce infection transmission.

Isolation and Quarantine Regulations

Certain diseases, like tuberculosis and Ebola, can lead to federal isolation or quarantine orders for patients.
Steps for establishing a sterile field include planning the layout, cleaning surfaces, and ensuring all items are sterile.

Cleaning Techniques and Isolation Precautions

Different cleaning methods should be matched with their uses, like disinfecting for surfaces and sterilizing for instruments.
Nursing actions for patients with cellulitis may include monitoring and antibiotic administration, while meningitis requires isolation precautions.

Definitions and Procedures

The term for medication administration by a nurse is "nursing intervention."
First step in donning PPE is hand hygiene.
An N95 mask is required for infections like tuberculosis that require airborne precautions.

Patient Interaction and Hand Hygiene

Explaining the need for PPE to patients is essential for transparency and trust.
Consistent use of gloves is necessary for any patient care involving body secretions.
Alcohol-based hand sanitizer is permissible when hands are not visibly soiled.

Respiratory Etiquette and Educational Corrections

Observing lack of respiratory etiquette indicates a need for further patient education.
Correct nursing students' notes may involve clarifying infection control protocols.
Contact precautions are necessary for infections like MRSA.

Transmission-Based Precautions

Droplet transmission necessitates protective precautions for infections such as the flu.
Airborne precaution rooms are designated for infections like measles or COVID-19.
Understanding the mode of transmission helps determine the appropriate type of precaution.

Community and CDC Guidelines

Quarantine applies to exposed individuals, including travelers returning from outbreaks or those infected.
Nurses' independent interventions can involve hand hygiene practices and patient education.

Aseptic Techniques and Surgical Procedures

Maintaining a sterile field involves avoiding breaches such as reaching over sterile areas.
Surgical procedures require sterilization of equipment entering sterile body cavities.
Clostridium difficile tests indicate a suspicion of clostridial infection based on symptoms.

Temperature and Nursing Interventions

Following an infection, a nurse expects the patient’s temperature to be less than 100.4°F (38°C).
Independent nursing interventions can include educating patients about infection prevention practices and monitoring vital signs.
