- Q1What is the definition of a true pathogen?B) needs to passed from one person to the nextA) does not require a weakened host to cause diseaseE) must cause diarrhea, vomiting, and fever in the patientD) causes disease within one week of infecting the patientC) must be a bacterial or viral pathogen30s
- Q2***Endemic infectionsC) are infections that have only been recorded within the past 1,000 years and not before.B) are isolated infections in a particular population.E) are infections that are life threatening if not treated in a timely manner.D) are infections that are expected to be cured and wiped out by the year 2050.A) are routinely detected in a population or region.30s
- Q3What is a pandemic?B) a widespread disease outbreak that spreads to numerous countries during a specific time frameD) an infection routinely detected in a population or regionE) an infection where the host does not have signs or symptomsC) isolated infections in a particular populationA) a widespread disease outbreak in a particular region during a specific time frame30s
- Q4How is a reemerging pathogen different from an emerging pathogen?C) A reemerging pathogen is an infectious agent that was under control due to prevention or treatment strategies but is now resurfacing.A) A reemerging pathogen is an infectious bacterial infection that manifests once every few months but goes away without treatment and only blisters the skin in another few months.E) A reemerging pathogen is an infectious agent that went away when the patient was taking antibiotics but quickly returned when the patient stopped taking the antibiotics.B) A reemerging pathogen is an infectious helminth that was detected in one location of the body but receded and emerged from a second location.D) A reemerging pathogen is an infectious agent that was identified previously in one location but is now emerging in a new separate location.30s
- Q5Why are Koch's postulates important to microbiology?A) They demonstrate the preferred route of infection for a particular disease.C) They enable us to characterize the species of the infectious disease whether it is a bacteria, virus, or fungi.B) They provide a way to select the most effective concentration of antibiotic to use for a patient.D) They allow us to identify the causative pathogens of many infectious diseases.E) They explain how a particular disease produces specified signs in a patient.30s
- Q6Which of the following pathogenic agents is multicellular?E) helminthsC) bacteriaA) prionsD) protozoansB) viruses30s
- Q7Which of the following is an endogenous source of infection?B) contaminated medical equipmentE) contact with another personC) zoonotic diseaseD) bacteria from the skin entering a surgical incisionA) contaminated food30s
- Q8***Which of the following is an indirect infectious disease transmission mode?C) vehicleD) environmentE) verticalB) animalA) person to person30s
- Q9Which of the following infectious disease transmission modes is not correctly paired with an example?E) Flea bite: PlagueD) Touching: Cat-scratch feverA) Swimming: Swimmer's earC) Breast milk: HIVB) Windborne: Cholera30s
- Q10It is called a ________ vector when the vector has a role in the pathogen's life cycle.C) fomiteB) mechanicalA) biologicalD) vehicleE) zoonotic30s
- Q11***What is the order of the five stages of infectious disease?A) acute phase, incubation period, prodromal phase, convalescent phase, period of declineC) acute phase, prodromal phase, incubation period, convalescent phase, period of declineE) incubation period, acute phase, prodromal phase, convalescent phase, period of declineB) incubation period, prodromal phase, acute phase, period of decline, convalescent phaseD) prodromal phase, acute phase, incubation period, period of decline, convalescent phase30s
- Q12*** If you had to choose to be either a chronic carrier or an asymptomatic carrier, which would you choose and why?C) asymptomatic carrier because I wouldn't experience any symptomsA) chronic carrier because I would be infected but never show signs or symptomsE) asymptomatic carrier because after the initial symptomatic infection I would only experience symptoms from time to timeB) chronic carrier because I would only spread the infection when having symptomsD) asymptomatic carrier because I wouldn't spread the infection30s
- Q13***Of the following goals listed, which two statements best encompass the general goals of epidemiology? I. Isolate the infectious pathogen for study and vaccine creation II. describe the nature, cause, and extent of new or existing diseases in populations III. identify patient zero and how the initial infection occurred IV. intervene to protect and improve health in populations V. distribute vaccines so that future outbreaks do not occurC) I and IIIA) I and IIB) III and VD) II and IVE) III and IV30s
- Q14When is knowing the host and environmental factors that lead to a disease more important to saving lives than knowing the etiological causative agent?A) when the disease is spread through sexual contactE) when there is no cure for the diseaseD) when specific health factors within a person's control are particularly riskyC) when the host range is very largeB) when the source of infection is a particular geographical location30s
- Q15What are the three factors of the epidemiological triangle?B) survivability, length of acute phase, cultural factorsE) environmental factors, etiological agent, and host factorsC) pathogen type, host health, and geographic overlapD) vaccine use, disinfectant use, and hand-washing policyA) time from exposure to symptoms, access to transportation, quality of hospitals30s
