BIO104 CH14+ INFECTION CONTROL pptx
| Question | Answer |
|---|---|
| BIO104 (+ to CH14) INFECTION CONTROL | |
| What does pathogenicity refer to? A. How much damage a pathogen causes B. How quickly a pathogen reproduces C. The ability of a microorganism to produce disease D. The way a microorganism leaves the body | C. The ability of a microorganism to produce disease TIP: Pathogenicity = CAN it cause disease? YES or NO? |
| Which statement correctly compares pathogenicity and virulence? A. Pathogenicity measures severity; virulence determines whether disease is possible B. Pathogenicity asks whether it can cause disease; virulence describes the degree/intensity of damage C. They mean exactly the same thing D. Pathogenicity applies only to bacteria and virulence only to viruses | B. Pathogenicity asks whether it can cause disease; virulence describes the degree/intensity of damage |
| PATHOGENICITY = VIRULENCE = | CAN it cause disease? HOW BAD is the disease/damage? |
| Which statement about bacteria is correct? A. They have several nuclei B. They are multicellular organisms C. They are single-celled and lack a true nucleus D. They must live inside another cell | C. They are single-celled and lack a true nucleus TIP: BACTERIA = ONE CELL + NO TRUE NUCLEUS |
| Which pathogens are identified as the SMALLEST pathogens and only live inside cells? A. Bacteria B. Fungi C. Protozoa D. Viruses | D. Viruses TIP: VIRUS = VERY tiny |
| What do viruses do to the cells they inhabit? A. Protect them from bacteria B. Cause them to reproduce faster C. Damage and kill them D. Turn them into antibodies | C. Damage and kill them |
| Diseases produced by fungi are called: A. Virulences B. Helminths C. Mycoses D. Rickettsiae | C. Mycoses |
| Fungi can obtain food from: A. Antibodies B. Red blood cells only C. Living organisms or organic matter (non-living) D. Viruses only | C. Living organisms or organic matter (non-living) |
| Protozoa are: A. Multicellular worms B. A special type of bacteria C. Single-celled parasitic organisms D. Viruses that live inside cells | C. Single-celled parasitic organisms |
| Which of the following is a characteristic of protozoa? A. They cannot move B. They have the ability to move C. They are multicellular D. They are bacteria | B. They have the ability to move |
| Protozoa obtain food from: A. Living red blood cells only B. Antibodies C. Dead or decaying organic matter D. Bone marrow | C. Dead or decaying organic matter |
| Rickettsia are actually a type of: A. Virus B. Fungus C. Protozoan D. Bacteria | D. Bacteria |
| Rickettsia need to live: A. In dead organic matter B. Outside the body C. Inside cells D. Only in water | C. Inside cells Rickettsia = BACTERIA that need to live INSIDE CELLS. |
| Rickettsia can be spread through bites from: A. Mosquitoes only B. Dogs and cats C. Fleas, ticks, mites, and lice D. Worms and fungi | C. Fleas, ticks, mites, and lice |
| Fleas, ticks, mites, and lice that transmit Rickettsia are referred to as: A. Reservoirs B. Portals C. Hosts D. Vectors | D. Vectors |
| Helminths are: A. Single-celled bacteria B. Viruses C. Parasitic worms D. Fungi | C. Parasitic worms |
| Which are the most common helminths? A. Fleas and ticks B. Amoebas and paramecia C. Pinworms and tapeworms D. Mites and lice | C. Pinworms and tapeworms |
| What is the FIRST link in the Chain of Infection? A. Infectious agent B. Reservoir or source C. Portal of exit D. Susceptible host | A. Infectious agent |
| Which sequence correctly represents the Chain of Infection? A. Reservoir → infectious agent → portal of entry → portal of exit → transmission → host B. Infectious agent → reservoir → portal of exit → mode of transmission → portal of entry → susceptible host C. Infectious agent → transmission → reservoir → susceptible host → portal of exit → portal of entry D. Susceptible host → infectious agent → reservoir → transmission → portal of entry → portal of exit | B. Infectious agent → reservoir → portal of exit → mode of transmission → portal of entry → susceptible host |
| mnemonic for the CHAIN OF INFECTION: I Really Prioritize My Patients' Safety | I - Infectious Agent R - Reservoir P - Portal of Exit M - Mode of Transmission P - Portal of Entry S - Susceptible Host |
| Which two things are ways of breaking the Chain of Infection? A. Antibiotics and vaccines B. Isolation and medication C. Hygiene and PPE D. Antibodies and antigens | C. Hygiene and PPE |
| A nosocomial infection, or HAI, is an infection that is: A. Inherited genetically B. Acquired only at home C. Present in all healthy people D. Acquired in a health care facility | D. Acquired in a health care facility |
| Which type of pathogen is a single-cell organism that can form colonies? A. Virus B. Bacteria C. Helminth D. Fungus | B. Bacteria |
| Which pathogen is often described as “non-living” and requires cells to reproduce? A. Bacteria B. Protozoa C. Virus D. Helminth | C. Virus |
| Which type of pathogen may look like a plant and feeds on dead, dying, or easily accessible body tissues? A. Protozoa B. Rickettsia C. Fungi D. Viruses | C. Fungi |
| Skin and mucosal membranes are examples of easily accessible body tissues that may be affected by: A. Helminths B. Fungi C. Viruses only D. Rickettsia | B. Fungi |
| Which pathogens are free-living, single-cell organisms that are NOT bacteria? A. Fungi B. Viruses C. Protozoa D. Helminths | C. Protozoa |

| In the Chain of Infection, what is a reservoir? A. The way a pathogen enters a new host B. The way a pathogen is transmitted C. The place where a pathogen normally lives and multiplies D. The opening through which a pathogen leaves | C. The place where a pathogen normally lives and multiplies |
| Which of the following can serve as a reservoir for pathogens? A. Humans only B. Animals only C. Environment only D. Humans, animals, or the environment | D. Humans, animals, or the environment |
| Which of the following is one of the most common categories of nosocomial infections/HAIs? A. Urinary tract infection B. Poison ivy C. Rheumatoid arthritis D. Tapeworm infection | A. Urinary tract infection |
| Which type of wound infection is listed as a common category of HAI? A. Animal bite B. Burn wound C. Surgical wound D. Insect bite | C. Surgical wound |
| Which respiratory infection is listed as a common category of nosocomial infection? A. Asthma B. Bronchitis C. Pneumonia D. Allergic rhinitis | C. Pneumonia |
| Which bloodstream condition is listed as a common category of nosocomial infection/HAI? A. Anemia B. Leukopenia C. Septicemia D. Hemophilia | C. Septicemia |
