Why is asepsis so important?
Correct Answer
prevent spread of germs
prevent spread of infection
prevent infectionExplanation
Asepsis is important because it helps prevent the spread of germs, infections, and further complications. By practicing aseptic techniques, such as washing hands regularly, using sterile equipment, and maintaining a clean environment, the risk of transmitting harmful microorganisms is significantly reduced. This is crucial in healthcare settings to protect both patients and healthcare workers from acquiring and spreading infections. Proper aseptic practices also play a key role in preventing the development of infections in wounds or during medical procedures, ultimately promoting better patient outcomes.Rate this question:

Microorganisms are divided into two main groups: ______ or _____ (harmless, beneficial microorganisms) and ___ (microorganisms that cause illness).
Correct Answer
nonpathogens or normal flora and pathogens
normal flora or nonpathogens and pathogensExplanation
Microorganisms are classified into two main groups based on their effects on living organisms. The first group is nonpathogens or normal flora, which refers to microorganisms that are harmless or beneficial to the host organism. These microorganisms can help with various functions such as digestion and immune system regulation. The second group is pathogens, which are microorganisms that cause illness or disease in the host organism. These microorganisms can invade and multiply within the host, leading to various infections and health issues.Rate this question:

Communicable diseases are diseases that can be transmitted to other people are also called contagious diseases and community-acquired infections.
- A.
TRUE
- B.
FALSE
Correct Answer
A. TRUEExplanation
Communicable diseases are indeed diseases that can be transmitted to other people. These diseases can be spread through various means such as direct contact, airborne droplets, or contaminated surfaces. They are also commonly referred to as contagious diseases and community-acquired infections because they can easily spread within a community or population.Rate this question:

Microorganisms that include yeast and molds and are local in skin and under nails.
- A.
Viruses
- B.
Fungi
- C.
Protozoans
- D.
Prions
Correct Answer
B. FungiExplanation
Fungi are microorganisms that include yeast and molds and are commonly found on the skin and under nails. Unlike viruses, which are not considered living organisms, fungi are living organisms that can reproduce and grow. Protozoans are single-celled organisms, while prions are infectious proteins. Therefore, fungi is the correct answer in this context.Rate this question:

The smallest microorganisms known to cause infectious diseases. Can be self-limiting or fatal. Needs a host. Can stay dormant in the form of a spore. They are filterable.
- A.
Bacteria
- B.
Fungi
- C.
Rickettsiae
- D.
Viruses
Correct Answer
D. VirusesExplanation
Viruses are the smallest microorganisms that can cause infectious diseases. They can range from being self-limiting to fatal depending on the specific virus and the individual's immune response. Viruses require a host to reproduce and survive, as they cannot replicate on their own. They have the ability to remain dormant in the form of a spore, allowing them to survive in unfavorable conditions. Additionally, viruses are filterable, meaning they can pass through filters that can trap larger microorganisms like bacteria and fungi.Rate this question:

Type of microorganism that resembles bacteria. Cannot survive without a host. Examples: lyme disease.
- A.
Viruses
- B.
Helminths
- C.
Rickettsiae
- D.
Fungi
Correct Answer
C. RickettsiaeExplanation
Rickettsiae are a type of microorganism that resemble bacteria. They are obligate intracellular parasites, meaning they cannot survive without a host. Examples of diseases caused by rickettsiae include Lyme disease.Rate this question:

The largest single-celled microorganism. Round-cocci, rod shaped-bacilli, spiral-spirochetes. Aerobic or anaerobic
- A.
Protozoans
- B.
Rickettsiae
- C.
Fungi
- D.
Bacteria
Correct Answer
D. BacteriaExplanation
The correct answer is bacteria. Bacteria are single-celled microorganisms that can have various shapes, including round-cocci, rod-shaped bacilli, or spiral spirochetes. They can be aerobic or anaerobic, meaning they can survive with or without oxygen. Protozoans, rickettsiae, and fungi are also microorganisms, but they are not the largest single-celled microorganism as stated in the question.Rate this question:

Protozoans lack a cell wall.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Protozoans do not lack a cell wall. In fact, they are characterized by the absence of a rigid cell wall, which distinguishes them from other microorganisms such as bacteria and fungi. Instead, protozoans have a flexible cell membrane that allows for movement and other cellular processes.Rate this question:

Helminths are infectious worms.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Helminths are a type of parasitic worm that can infect humans and animals. These worms can cause a variety of diseases and health issues. Therefore, it is correct to say that helminths are infectious worms.Rate this question:
-

Protozoans are single celled animals.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Protozoans are single-celled organisms that belong to the kingdom Protista. They are eukaryotic organisms, meaning they have a true nucleus and other membrane-bound organelles. They are typically microscopic in size and can be found in various environments, including freshwater, marine, and terrestrial habitats. Protozoans exhibit a wide range of shapes and forms and can be classified into various groups based on their locomotion and feeding mechanisms. As single-celled animals, they carry out all essential life processes within a single cell, including reproduction, feeding, and excretion. Therefore, the statement "Protozoans are single-celled animals" is true.Rate this question:

A prion is a protein containing nucleic acid.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Prions are actually proteins that are misfolded and can cause diseases. They do not contain nucleic acid, which is the genetic material found in cells. Therefore, the statement that a prion is a protein containing nucleic acid is false.Rate this question:

The chain of infection is a sequence that enables the spread of disease-producing microorganisms. List the six links in the chain in order. (review this section in your textbook pgs. 136-138)
Correct Answer
infectious agent, reservoir, exit route, mode of transmission, port of entry, susceptible hostExplanation
The chain of infection starts with an infectious agent, which is the microorganism that causes the disease. The reservoir refers to the source or habitat where the infectious agent lives and multiplies. The exit route is the way in which the infectious agent leaves the reservoir, such as through bodily fluids or respiratory droplets. The mode of transmission is the method by which the infectious agent is passed from one person to another, such as through direct contact or airborne transmission. The port of entry is the route through which the infectious agent enters a new host, such as through broken skin or inhalation. Finally, the susceptible host is the individual who is at risk of becoming infected by the infectious agent.Rate this question:

Infections acquired while a person is receiving care in a health care agency
- A.
Nosocomial
- B.
Communicable
- C.
Contagious
- D.
Asepsis
Correct Answer
A. NosocomialExplanation
Nosocomial refers to infections that are acquired while a person is receiving care in a healthcare agency. This term specifically denotes infections that are contracted within a healthcare setting, such as hospitals, clinics, or nursing homes. It distinguishes these infections from those that are acquired in the community or elsewhere. The term nosocomial is used to highlight the potential risks and challenges associated with healthcare-associated infections, and it emphasizes the need for infection control measures in healthcare settings.Rate this question:
