EXAM QUESTIONS AND CORRECT
ANSWERS
●● Identify role of DNA changes in congenital abnormalities.
Answer: Mutations in genes or chromosomal abnormalities
●● How does development disrupts congenital abnormalities?
Answer: Alterations of DNA
●● Describes factors that disrupt homeostasis and how disruptions affect
wellbeing.
Answer: (ex) Fluid and electrolyte shifts can cause n/v or dysrhythmias.
●● Explain RAAS
Answer: Renin-angiotensin-aldosterone system
1. Reduce blood flow causes kidneys to release renin
> produce angiotensin I > converts angiotensin I to angiotensin II >
vasoconstriction > release aldosterone > kidneys conserve sodium and
water > Result less water lost in urine and blood pressure maintained.
