WGU Pathophysiology D236 Exam 150 Questions with Correct Answers
1. Describe how your body responds to an infection.: T cells produce
cy- tokines, which stimulate B cells. B cells produce antibodies.
2. Identify role of DNA changes in congenital abnormalities.: Mutations
ingenes or chromosomal abnormalities
3. How does development disrupts congenital abnormalities?: Alterations
ofDNA
4. Describes factors that disrupt homeostasis and how disruptions
affectwellbeing.: (ex) Fluid and electrolyte shifts can cause n/v or
dysrhythmias.
5. Explain RAAS: Renin-angiotensin-aldosterone system
1. Reduce blood flow causes kidneys to release renin
> produce angiotensin I > converts angiotensin I to angiotensin II > vasoconstric-
tion > release aldosterone > kidneys conserve sodium and water > Result less
water lost in urine and blood pressure maintained.
6. DKA: increased anion gap, decreased HCO3
7. How do kidneys compensate for alkalosis: retain H and excrete HCO3
8. Untreated acidosis leads to an increase in which electrolyte?: Potassium
9. West Nile Virus: Transmitted through the bite of an infected mosquito. Severe
signs and symptoms; high fever, headache and stiff neck
10. Lyme disease: Tick-borne disease caused by the spirochete Borrelia burgdor-
feri.
11. Erythema infectiosum: a febrile upper respiratory illness in a child followed
by the sudden appearance of red, flushed cheeks, "fifth disease"
12. Obesity ad diabetes are risk factors for having a child with .: Spina
bifida
13. Trousseau's sign: arm/carpal spasm associated with hypocalcemia
14. Cause and sign of spina bifida: results from failure of neural tube to close.
sign - fluid filled sac on lower back.
, 15. hemophilia is more common in: males
16. Prenatal exposure to alcohol includes: ND-PAE, decreased brain function,
FAS
17. Connective vs muscle tissue disorders: Connective- RA, Scleroderma, Lu-
pus
