2025 | HIGH-YIELD QUESTIONS & DETAILED ANSWERS FOR
A+ SUCCESS
✅
Antiseptic
A substance that tends to inhibit the growth and reproduction of microorganisms;
may be used on humans.
✅
Asepsis
Free of pathogenic microorganisms.
✅ A person or animal that harbors and spreads an organism, causing disease in
Carrier
others, but does not itself become ill.
✅
Centers for Disease Control and Prevention (CDC)
Federal agency that provides facilities and services for investigation, identification,
prevention, and control of disease; headquartered in Atlanta, Georgia.
✅
Contamination
Condition of being soiled, stained, touched, or otherwise exposed to harmful agents
by the entry of infectious or toxic material into a previously clean or sterile environment,
making an object potentially unsafe for use as intended.
✅
Disinfection
Process by which pathogens, but not necessarily their spores, are destroyed.
✅ Growing within the body; originating from within the body, or produced from internal
Endogenous
causes, such as a disease caused by the structural or functional failure of an organ or
system.
✅
Exogenous
Outside the body; originating outside the body or produced from external causes,
such as a disease caused by a bacterial or viral agent foreign to the body.
✅
Fomite
Nonliving material, such as bed linens, stethoscopes, needles, and many other
objects that may host and transfer pathogenic microorganisms.
,✅
Health Care–Associated Infection (HAI)
Infection that develops at least 48 hours after hospitalization or contact with another
type of health care facility.
✅
Host
A person or group who, because of risk factors, may be susceptible to disease or
illness; an organism in which another, usually parasitic, organism is nourished and
harbored.
✅
Infection Prevention and Control
Implementation of policies and procedures in hospitals and other healthcare
facilities to minimize the spread of healthcare-associated or community-acquired
infections to patients and staff.
✅
Medical Asepsis (Clean Technique)
A group of techniques that inhibit the growth and spread of pathogenic
microorganisms.
✅
Microorganism
Tiny, unusual microscopic entities capable of carrying on living processes.
✅ Any natural habitat of a microorganism that promotes growth and reproduction.
Reservoir
✅ The reproductive cell of some microorganisms such as fungi or protozoa. These
Spore
cells are highly resistant to heat and chemicals. Under proper environmental conditions,
they may revert to an actively multiplying form of bacterium.
✅
Standard Precautions
A set of guidelines by the CDC to reduce the risk of transmission of blood-borne
pathogens and other infectious agents. Includes hand-washing and use of gloves,
masks, gowns, and eye protection when appropriate.
✅
Sterilization
A process by which all microorganisms, including their spores, are destroyed.
✅ A group of techniques that destroys all microorganisms and their spores.
Surgical Asepsis (Sterile Technique)
✅ A living carrier for the transmission of microorganisms.
Vector
, ✅
Vehicle
The means by which organisms are carried about.
✅ Having the power to produce disease, highly pathogenic or rapidly progressive.
Virulent
TRUE OR FALSE QUESTIONS
1. Following isolation precautions is the most important method of reducing the
✅
spread of microorganisms.
Correct Answer: False
2. Immunocompromised patients admitted to healthcare facilities have an increased
risk of exposure to multidrug-resistant Staphylococcus aureus (MRSA) and are
✅
therefore more difficult to treat.
Correct Answer: True
3. One exception to the self-limiting nature of viral infections is Acquired
✅
Immunodeficiency Syndrome (AIDS).
Correct Answer: True
4. Protozoa are responsible for Valley Fever and Histoplasmosis, which are
✅
systemic fungal respiratory diseases.
Correct Answer: False
5. An accidental needlestick is an example of a portal of exit in the chain of
✅
infection.
Correct Answer: False
✅
6. Microorganisms are present only in susceptible hosts.
Correct Answer: False
7. Healthcare-associated infections (HAIs) are most commonly transmitted by direct
✅
contact between healthcare workers and patients, or from patient to patient.
Correct Answer: True
✅
8. HIV is the most commonly transmitted infection by contaminated needles.
Correct Answer: False
9. The prodromal stage is often the period in which the individual is most
contagious.
