WGU Pathophysiology D236 Questions &
Answers 100% Correct!!
Describe how your body responds to an infection. - ANSWER-T cells produce cytokines, which
stimulate B cells. B cells produce antibodies.
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.
DKA - ANSWER-increased anion gap, decreased HCO3
How do kidneys compensate for alkalosis - ANSWER-retain H and excrete HCO3
Untreated acidosis leads to an increase in which electrolyte? - ANSWER-Potassium

porous, brittle, and easily fractured.
osteomalacia - ANSWER-disease marked by softening of the bone caused by calcium and vitamin D
deficiency
myoglobin - ANSWER-red pigment that stores oxygen in muscle cells
