The body's first line of defense, including physical barriers like skin and mucous membranes, and chemical barriers like stomach acid.

The second line of defense, involving non-specific immune cells like phagocytes and natural killer cells, as well as the inflammatory response.

The third line of defense, involving specific immune cells like B cells and T cells, creating a memory for future encounters with pathogens.

A weak immune system, chronic conditions, poor hygiene, age (very young or elderly), and hospitalization or surgery.

The stage where the pathogen enters the body but no symptoms are noticeable.

The stage of mild symptoms, often fatigue, headache, or body aches.

The stage when the infection reaches its peak, with the most severe and specific symptoms.

The stage when the immune system starts to overcome the infection, and symptoms begin to decrease.

The final recovery stage where the body returns to its normal state.

Infection confined to a specific area, often causing redness, swelling, warmth, pain, and pus.

Practices used to prevent the spread of infections, including proper handwashing, use of personal protective equipment (PPE), and respiratory hygiene.

Precautions applied to patients known or suspected to be infected with certain pathogens. Examples include contact, droplet, and airborne precautions.

Wearing gloves and a gown when caring for a patient or interacting with their environment, used to prevent the spread of infections through direct contact.

Wearing a mask when in close proximity to a patient, used to prevent the spread of infections through respiratory droplets.

Wearing an N95 respirator, used to prevent the spread of infections through small airborne particles that can remain suspended in the air for longer periods.

Practices that aim to reduce the number of pathogens on surfaces and in the environment, using methods like handwashing, disinfection, and barriers. Examples include cleaning a bedside table.

Practices that eliminate all pathogens from surfaces and objects, used in procedures like surgeries and injections. Procedures involving sterile equipment.

Any tear, wetness, expired date, or damage on sterile packaging or equipment indicates a potential contamination, making it unsuitable for use.

New or emerging pathogens and infectious diseases present a threat to public health. Nurses play a critical role in surveillance, patient education, and infection control practices.

The nurse's role in addressing emerging infectious diseases includes surveillance, patient education, infection control practices, and advocating for vaccination.
