BSNC 4000: PH Questions with Complete
Solutions
Primary level of prevention Correct Answer-Health promotion and
illness prevention
Secondary level of prevention Correct Answer-early detection,
screening, and management of disease
Tertiary level of prevention Correct Answer-restoration and
rehabilitation
Immunity Correct Answer-protection from disease
When do we develop innate immunity? Correct Answer-At birth and
before exposure
When do we develop adaptive immunity? Correct Answer-Vaccinations
and exposure
What does innate immunity respond to? Correct Answer-All pathogens
with an immediate response
What does adaptive immunity respond to? Correct Answer-Specific
pathogens to provide long term immunity due to memory
, What cells does adaptive immunity include? Correct Answer-B-cells and
T-cells
What do B-cells do? Correct Answer-Extracellular antibody production
What do T-cells do? Correct Answer-Destroy intracellular pathogens
What are helper T-cells? Correct Answer-Enhance immune response
What are regulatory T-cells? Correct Answer-Decrease immune
response to prevent self attack
What are cytotoxic T-cells? Correct Answer-Destroy infected cells
What is VDJ recombination? Correct Answer-B and T cells are
produced, and helper T-cells have a protein on them that require
differentiation into TH1 or TH2
What is TH1? Correct Answer-Works intracellularly to activate
cytotoxic T-cells = attack intracellular infected cells
What is TH2? Correct Answer-Works extracellular to activate B cells =
antibody production
