Which of the following is a component of the chain of infection that involves the strength of the pathogen?

• Number of microorganisms

• Virulence/infectious agent

• Susceptible host

• Portal of entry

In a dental office, which mode of transmission occurs when a pathogen is spread through the air?

• Direct transmission

• Indirect transmission

• Airborne transmission

• Parenteral transmission

Identify the mode of transmission that involves the transfer of pathogens through a needle stick injury.

• Direct transmission

• Indirect transmission

• Airborne transmission

• Parenteral transmission

Which of the following is a method to prevent cross-contamination from the dental team to the patient?

• Using disposable gloves

• Sharing dental instruments

• Reusing masks

• Not washing hands

What is the role of maintaining aseptic conditions in a dental office?

• To increase the number of microorganisms

• To prevent disease transmission

• To make the environment more comfortable

• To reduce the cost of dental procedures

Which component of the chain of infection is directly affected by the immune status of an individual?

• Virulence/infectious agent

• Number of microorganisms

• Susceptible host

• Portal of entry

What is the primary purpose of identifying the portal of entry in the chain of infection?

• To determine the strength of the pathogen

• To identify how the pathogen enters the host

• To measure the number of microorganisms

• To assess the susceptibility of the host

Which mode of transmission involves the transfer of pathogens from one patient to another through contaminated instruments?

• Direct transmission

• Indirect transmission

• Airborne transmission

• Bloodborne transmission

How can a dental office prevent cross-contamination from the community to the dental office?

• By sterilizing dental instruments

• By using personal protective equipment

• By implementing proper waste disposal

• By increasing patient appointments

Which of the following is a bloodborne mode of transmission in a dental office?

• Airborne transmission

• Direct transmission
