HSC 300 EXAM 1 COMPLETE TEST PAPER
WITH CORRECT ANSWERS
◉ What are the normal defenses of the body against infection.
Answer: Normal defenses include skin, mucous membranes, cilia,
saliva, and normal flora.
◉ What are the stages of infection.
Answer: The stages include incubation, prodromal, illness, decline,
and convalescence.
◉ What characterizes colonization by pathogens.
Answer: Colonization is the presence and growth of microorganisms
within a host without tissue invasion or damage, often
asymptomatic.
◉ What differentiates an infection from colonization?.
Answer: Infection occurs when a pathogen invades tissues and
begins to grow, leading to symptoms.
◉ What are healthcare-associated infections (HAIs)?.
,Answer: HAIs are infections that occur after admission to a
healthcare facility due to invasive procedures, contaminated sources,
or breaks in infection control.
◉ What are some common examples of multidrug-resistant
organisms (MDROs)?.
Answer: Examples include MRSA (methicillin-resistant
Staphylococcus aureus) and VRE (vancomycin-resistant
enterococci).
◉ What are the modes of transmission for infections?.
Answer: Modes include contact, droplet, airborne, and vector-borne
transmission.
◉ What is the purpose of medical asepsis?.
Answer: Medical asepsis aims to control or eliminate infectious
agents through cleaning, disinfection, and sterilization.
◉ What are the signs of infection?.
Answer: Signs include erythema (redness), warmth, edema,
purulent discharge, and fever.
◉ What is the role of the inflammatory response?.
, Answer: The inflammatory response includes vascular/cellular
responses, fever, and exudate formation to combat infection.
◉ What factors influence a person's risk for infection?.
Answer: Factors include age, nutritional status, stress levels,
comorbidities, and disease processes.
◉ What precautions are taken to prevent the spread of infections?.
Answer: Precautions include hand hygiene, use of personal
protective equipment (PPE), and controlling portals of exit/entry.
◉ What is the significance of the incubation period?.
Answer: The incubation period is the time between contact with a
pathogen and the appearance of the first symptoms.
◉ What are the symptoms of a localized infection?.
Answer: Localized infections typically show symptoms such as
redness, swelling, and pain at the infection site.
◉ How do systemic infections differ from localized infections?.
Answer: Systemic infections affect the entire body and may present
with fever, fatigue, and widespread symptoms.
