Q

What is airborne transmission?

A

Airborne transmission involves spreading infectious agents through droplets or dust in the air. For example, sneezing can transmit diseases like the common cold or COVID-19.

Q

How can you prevent transmission of airborne pathogens?

A

Avoid covering your cough or sneeze with your hands. Instead, cough or sneeze into your elbow or use a tissue to minimize the spread of organisms.

Q

What is foodborne transmission?

A

Foodborne transmission occurs when food or water becomes contaminated with disease-causing organisms. Proper food handling, storage, and cleanliness help prevent this type of transmission.

Q

What is vector-borne transmission?

A

Vector-borne transmission involves the spread of infection by animals or insects that carry organisms from one person or place to another, such as fleas transmitting the bubonic plague.

Q

What is the role of the Occupational Safety and Health Administration (OSHA)?

A

OSHA develops and publishes guidelines to reduce hazards in the workplace and is responsible for enforcing these guidelines, including those related to bloodborne pathogens and infectious diseases.

Q

What are standard precautions?

A

Standard precautions are protective measures designed to prevent health care workers from coming into contact with objects, blood, body fluids, and other potential risks that could lead to exposure to germs.

17
Q

What should you do if you are exposed to an infectious disease?

A

You must notify your designated officer if you are exposed to an infectious disease.

18
Q

How can immunity to a disease be gained?

A

Immunity can be gained through vaccination or by recovering from an infection, which allows the body to recognize and repel the pathogen if it appears again.

19
Q

What is the difference between complete and partial immunity?

A

Complete immunity means lifelong protection against reinfection, while partial immunity protects against new infections but may not prevent reactivation of the original infection.

20
Q

Can the body become re-infected after developing immunity?

A

Yes, pathogens that remain in the body from a previous infection may cause reinfection if the immune system is weakened, as seen in diseases like tuberculosis.

21
Q

What is an example of an infection where immunity may not be effective?

A

HIV is an infection where the body struggles to mount an effective immune response, which can lead to AIDS.

22
Q

What does OSHA require for protection from occupational exposure to bloodborne pathogens?

A

OSHA requires employers to create an infection control plan and offer the hepatitis B vaccine to employees at no cost. Employees who decline must sign a waiver but may later decide to take the vaccine at the employer’s expense.

23
Q

What happens if an EMT is exposed to hepatitis B?

A

If exposed, the EMT will be tested for antibodies. If they have antibodies (due to previous vaccination), no treatment is needed. If they lack antibodies, they will receive hepatitis B immune globulin followed by a series of three hepatitis B immunization shots.

24
Q

Is there treatment to prevent hepatitis C after exposure?

A

No, there is no treatment available to prevent hepatitis C infection after exposure.

25
Q

What does “cover” mean in emt scene safety

A

Involves the tactical use of an impenetrable barrier for protection

26
Q

What does “concealment” mean in emt scene safety

A

Involves hiding behind objects to limit a persons ability to see you

27
Q

What are the stages of the body’s response to stress?

A

The stages are alarm response, reaction and resistance, followed by recovery or exhaustion if stress is prolonged. This is known as the general adaptation syndrome.

28
Q

What is the fight-or-flight response?

A

The fight-or-flight response is a physiological reaction where the endocrine and nervous systems trigger chemical and physical changes, preparing the body to either confront or flee from a stressor.

29
Q

What are some common physiological responses to stress?

A

Increased respirations, heart rate, and blood pressure; constricted venous vessels; dilated pupils; tensed muscles; increased blood glucose; perspiration; and decreased blood flow to the gastrointestinal tract.

30
Q

What is acute stress?

A

Acute stress reactions occur during a stressful situation, causing heightened focus and nervous energy. If unmanaged, it can lead to emotional and physical reactions that may overwhelm you.

31
Q

What is delayed stress?

A

Delayed stress reactions occur after a stressful event, where nervous energy continues to build, even after the crisis has passed.

32
Q

What is cumulative stress?

A

Cumulative stress happens after prolonged or excessive exposure to stress, making it harder to recover from each new stressful event. It can lead to physical and psychological symptoms like fatigue, irritability, and depression.

33
Q

What are some physical and psychological effects of cumulative stress?

A

Physical effects include fatigue, changes in appetite, gastrointestinal issues, and headaches. Psychological effects include depression, irritability, anxiety, and difficulty concentrating.

34
Q

What is critical incident stress?

A

Critical incident stress results from unusually severe or emotional events, such as mass-casualty incidents, traumatic deaths, or the injury or death of a coworker in the line of duty.

35
Q

What is posttraumatic stress disorder (PTSD)?

A

PTSD may develop after a psychologically distressing event, characterized by reexperiencing the event and overresponding to stimuli that recall it. Symptoms include depression, startle reactions, flashbacks, and dissociative episodes (e.g., amnesia of the event).

36
Q

What is critical incident stress management (CISM)?

A

CISM is a process designed to address acute stress situations and reduce the likelihood of PTSD. It involves confronting responses to critical incidents to help EMS personnel return to physical and emotional equilibrium.

37
Q

What are debriefing sessions in CISM?

A

Debriefing sessions occur 24 to 72 hours after a major incident, where participants express pent-up emotions. These sessions are led by CISM teams and should not be used for operational critiques.

38
Q

What is compassion fatigue?

A

Compassion fatigue, or secondary stress disorder, is the gradual loss of compassion over time, caused by caring for others who have experienced trauma. It differs from PTSD in that it is not caused by direct exposure to trauma.

39
Q

What are some symptoms of compassion fatigue?

A

Symptoms include high absenteeism, difficult relationships with colleagues, inability to work in teams, aggressive behavior toward patients, lack of empathy, negative attitudes toward work, and preoccupation with nonwork issues.
