QCM : Fundamentals of Infection Control — 9 questions

Explication

Infection control is defined as the policies and procedures implemented to prevent the spread of infectious diseases in healthcare and community environments. It involves practices like hand hygiene, use of PPE, and environmental cleaning to reduce pathogen transmission. The other options describe diagnostic methods, vaccine development, or sterilization techniques, which are related to infection prevention but do not encompass the broad concept of infection control as a set of policies and practices.

Explication

Ignaz Semmelweis is credited with pioneering hand hygiene practices in the 19th century, which significantly reduced puerperal fever. Joseph Lister contributed to antiseptics in surgery, but not specifically handwashing.

Explication

Ignaz Semmelweis is recognized as the 'Father of Hand Hygiene' because he demonstrated that handwashing with chlorinated lime solutions drastically reduced puerperal fever in obstetric clinics, establishing the importance of hand hygiene in infection control.

Explication

Joseph Lister developed antiseptic surgical methods in the 19th century using carbolic acid (phenol), greatly improving surgical outcomes. Semmelweis focused on hand hygiene, not antisepsis in surgery.

Explication

Classifying infections into types helps healthcare providers determine the most effective treatment and prevention strategies, as different pathogens require different approaches. For example, antibiotics are used for bacterial infections, antivirals for viral infections, antifungals for fungal infections, and antiparasitics for parasitic infections. This classification is essential for effective infection control and patient management.

Explication

The sheet states that about 1 in 10 patients worldwide acquire healthcare-associated infections, highlighting the global importance of infection control.

Explication

Ingestion of non-contaminated food is not a mode of transmission for infectious agents. Transmission modes include contact, droplet, airborne, and vector-borne routes.

Explication

Standard precautions are designed as universal measures to reduce infection risks in all settings, regardless of patient's infection status, covering practices like hand hygiene and PPE use.

Explication

A pathogen is any microorganism capable of causing disease, including bacteria, viruses, fungi, and parasites, but not terms like commensals or vectors which have different roles.
