DBT40013 Unit 3.3: Biological Hazard

What is the main aspect of bio-safety?

• Conducting a risk assessment on the infection and the disease

• Training employees on first aid

• Using personal protective equipment

• Implementing emergency response procedures

Answer explanation

Conducting a risk assessment on the infection and the disease is the main aspect of bio-safety.

What is the cause of disease in the Chain of Infection model?

• Portal of Exit

• Mode of Transmission

• Reservoir

• Agent

Answer explanation

The cause of disease in the Chain of Infection model is the Agent, which refers to the pathogen or microorganism responsible for causing the disease.

What is the reservoir in the Chain of Infection model?

• Where the agent must enter the new host

• Where the agent must be pathogenic

• Where the agent must be able to escape

• Where the agent must live and reproduce

Answer explanation

Where the agent must live and reproduce

What is the mode of transmission in the Chain of Infection model?

• Where the agent must move in the environment

• Where the agent must live and reproduce

• Where the agent must be able to escape

• Where the agent must be pathogenic

Answer explanation

The mode of transmission in the Chain of Infection model refers to where the agent must move in the environment, indicating how the infectious agent is spread from one host to another.

What is the susceptible host in the Chain of Infection model?

• Where the agent must be pathogenic

• Where the host is easily affected by the agent

• Where the agent must live and reproduce

• Where the agent must enter the new host

Answer explanation

The susceptible host in the Chain of Infection model is where the host is easily affected by the agent, making them vulnerable to infection.

What are Nosocomial Infections also known as?

• Community-acquired infections

• Hospital-acquired infections

• Travel-acquired infections

• Workplace-acquired infections

Answer explanation

Nosocomial Infections are also known as Hospital-acquired infections.

Which route of transmission involves insects and arthropods?

• Vector-Borne Transmission

• Airborne Transmission

• Direct Contact

• Indirect Contact

Answer explanation

The correct choice is Vector-Borne Transmission because this route of transmission involves insects and arthropods carrying and transmitting pathogens to humans or animals.

Which route of transmission occurs with microorganisms dispersed into the air?

• Vector-Borne Transmission

• Airborne Transmission

• Direct Contact

• Indirect Contact

Answer explanation

Airborne Transmission occurs when microorganisms are dispersed into the air.

What is the main focus of Working Safely with Biological Agents?

• Training employees on first aid

• Risk assessment on the infection and the disease

• Using personal protective equipment

• Implementing emergency response procedures

Answer explanation

The main focus of Working Safely with Biological Agents is risk assessment on the infection and the disease, ensuring proper understanding and management of potential hazards.

What is the interaction between Host, Agent, and Environment necessary for?

• To prevent contamination

• To organize events

• To cause disease or damage

• To identify control measures

Answer explanation

The interaction between Host, Agent, and Environment is necessary to cause disease or damage.
