NURS 1010 - Infection Questions with Verified Solutions
100% Correct
What is a microorganism (such Pathogen
as bacteria, viruses, fungi, or
parasites) that can cause
disease?
What are the primary agents of Pathogens
infection?
What is the collection of Normal Flora
microorganisms that naturally
inhabit the body without causing
disease under normal
conditions. However, if the
immune system is compromised
or if these organisms enter
sterile areas, they can become
pathogenic?
What is a life-threatening Sepsis
response to infection in which
the body's immune system
causes widespread
inflammation, potentially leading
to organ failure and death?
What is the degree of Virulence
pathogenicity of a
microorganism, indicating how
harmful or aggressive it is in
causing disease?
High virulent pathogens cause more severe infections
_____
What refers to infections caused Opportunistic
by microorganisms that normally
do not cause disease but take
advantage of weakened immune
systems or breaches in the
body's defenses?
What is the study of how Epidemiology
infections spread, their patterns
in populations, and ways to
prevent and control infectious
diseases?
Infection is the invasion and multiplication of microorganisms in
What is infection? body tissues, leading to disease due to toxin production,
intracellular replication, or an immune response.
, Localized: Confined to one area
What are the different types of Disseminated: Spreads from an initial site to other areas
infections based on spread?
Systemic: Affects the entire body (e.g., sepsis)
Epidemic: Higher-than-normal cases in a specific population or
What is the difference between area
an epidemic and a pandemic?
Pandemic: Worldwide epidemic
1. Bacteria - One-celled organisms that release toxins
(e.g.,Streptococcus, E. coli)
2. Viruses - Require a host to replicate (e.g., Influenza, HIV)
What are the four main
categories of infectious agents?
3. Fungi - Includes yeasts and molds (e.g., Candida, Aspergillus)
4. Parasites/Protozoa - Infect hosts via ingestion or vectors (e.g.,
Malaria, Giardia)
- Largest group: Asymptomatic carriers
What is the "Iceberg" concept in
- Smaller group: Mild symptoms
epidemiology?
- Smallest group: Severe, clinically diagnosed cases

5. Mode of transmission
6. Portal of entry

infections?
patients).
- Populations at risk: Infants, elderly, immunocompromised
individuals
What are key risk factors for
- Environmental: Poor sanitation, crowded conditions
infection?
- Medical conditions: Chronic diseases (e.g., diabetes, cancer),
immunosuppressive treatments
- General: Fever, chills, fatigue, malaise
What are common signs and
- Localized: Redness, swelling, pain, drainage
symptoms of infection?
- Systemic: Hypotension, tachycardia (in sepsis)
