Safety And Infection Control Exam Questions And Answers
Infection Control/Chain of Infection - Answer Medical asepsis and infection control are
imperative to the prevention and dissemination of disease
For microorganisms to survive certain growth requirements must be met present -
Answer Proper nutrition; Oxygen; Temperature; Darkness; Moisture; pH
Infectious Agent - Answer microorganisms that are categorized into fungi, viruses,
bacteria, fungi, and parasites.
Reservoir host - Answer one becomes infected by the pathogen and also serves as a
source of transfer of pathogen.
There are five main types of mode of transmission: - Answer Contact: direct and
indirect; Droplet such as a sneeze; Airborne; Common vehicle; Vector borne, a living
organism that carries a disease from 1 infeected person to another
Stages of Infectious Disease - Answer There are five identifiable stages of infection.
Stage One - Answer The incubation stage is a period when the pathogen has time to
grow and establish itself in the body
Stage Two - Answer The prodromal stage is a period when the patient may commence
feeling unwell or weariness is taking over.
Stage Three - Answer The acute stage is where specific symptoms become obvious
Stage Four - Answer The declining stage is where the symptoms begin to fade
, Stage Five - Answer Convalescent stage is where the patient is recovering
Protective Mechanisms of the Body - Answer protective mechanisms built in to prevent
us from the entrance of pathogens and to help break the infection cycle. Protective
mechanism are as followed:
Skin - Answer protective barrier against the entrance of microorganisms
Mucous membranes - Answer Lines the nose, throat, respiratory and gastrointestinal to
protect invasion of infection
Mucus and cilia - Found in the nose and respiratory tract repel pathogens
Coughing and sneezing -Serve to propel pathogens from the body
Tears and sweats - Secretions that clear pathogens from the body
Urine and vaginal secretions are acidic - Pathogens cannot tolerate acid
Hydrochloric acid - Hydrochloric acid favors digestion and the acidic environment
arrests the development of pathagens
Label biohazard specimens Answer Biohazard specimens must be labeled accordingly
to prevent its rejection from the laboratory
Specimens must have the following identification information - Answer Patient's full
name and date of birth; Patient's admission number to the hospital - inpatient d; Social
security number - outpatient; Time and date of collection;
