INFECTION PREVENTION CERTIFICATION
EVALUATION 2026 CONTROL PRACTICES
QUESTIONS AND SOLUTIONS VERIFIED
GRADED A+
●● What are normal host defenses?
Answer: Normal host defenses include physical barriers, immune
responses, and the inflammatory response that protect against infection.
●● What is the difference between localized and systemic infection?
Answer: Localized infection is confined to a specific area, while
systemic infection affects the entire body.
●● What are Standard Precautions?
Answer: Standard Precautions are infection control practices applied to
all patients, regardless of diagnosis, to prevent transmission.
●● What is the most effective method to prevent infection?
Answer: Hand hygiene is the single most effective method to prevent
infection.
●● What are Transmission-Based Precautions?
, Answer: Transmission-Based Precautions are additional infection
control measures used for patients known or suspected to be infected
with highly transmissible pathogens.
●● What is the role of Personal Protective Equipment (PPE) in infection
control?
Answer: PPE protects health care workers from exposure to infectious
agents and is used based on anticipated exposure.
●● What factors increase a patient's risk for infection?
Answer: Factors include decreased immune defenses, exposure to health
care-associated pathogens, and invasive procedures.
●● What is colonization in the context of infection?
Answer: Colonization is the presence and growth of microorganisms
within a host without causing tissue invasion or damage.
●● What are common portals of exit for pathogens?
Answer: Common portals of exit include respiratory, gastrointestinal,
reproductive, urinary tracts, skin and mucous membranes, and blood.
●● What are the means of transmission for infections?
Answer: Means of transmission include direct contact, indirect contact,
airborne, and droplet transmission.
