BIOS 242 CERTIFICATION EVALUATION
COMPLETE QUESTIONS AND SOLUTIONS
GRADED APLUS
●● nose, nasal cavity, pharynx, and uvula
Answer: components of the upper respiratory system
●● larynx, trachea, bronchi, alveoli, and diaphragm
Answer: components of the lower respiratory system
●● lower respiratory system
Answer: typically microorganisms are not present
●● upper respiratory system
Answer: colonized by many microorganisms, normal microbiome limits
growth of pathogens, and normal microbiome may be opportunistic
pathogens
●● pharyngitis
Answer: sore throat and difficulty swallowing and is often accompanied
by fever, malaise, and headache
,●● pharyngitis
Answer: complications include scarlet fever, rheumatic fever, and acute
glomerulonephritis occur in some cases
●● scarlet fever and rheumatic fever
Answer: antibodies react with cardiac tissue causing these secondary
infections after pharyngitis
●● when you have strep, antibodies bind and clump and get stuck in the
kidneys filtration system
Answer: why does acute glomerulonephritis occur after strep throat?
●● m protein
Answer: causes inhibition of complement component C3b, thereby
interfering with opsonization and lysis
●● hyaluronic acid capsule
Answer: may camouflage the bacterium from phagocytosis
●● streptokinases
Answer: enzymes that break down blood clots, presumably enable group
A streptoccci to spread rapidly through damaged tissues
, ●● C5a peptidase
Answer: an enzye that breaks down complement protein C5a, which is a
chemotactic factor.
●● pyrogenic toxins
Answer: stimulate leukocytes to release cytokines that in turn stimulate
fever, rash, and shock
●● streptolysins
Answer: lyse erythrocytes, leukocytes, and platelets
●● diptheria
Answer: sore throat, localized pain, and fever and the presence of a
pseudomembrane that can obstruct airways
●● diptheria
Answer: caused by corynebacterium diptheriae which produces diptheria
toxin
●● diptheria
Answer: spread via respiratory droplets or skin contact and diagnosis is
bases on presence of a pseudomembrane and treated with antitoxin and
antibiotic
