WGU PATHOPHYSIOLOGY D236 EXAM
QUESTIONS WITH COMPLETE
SOLUTIONS.
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
West Nile Virus - ANSWER- Transmitted through the bite of an infected
mosquito. Severe signs and symptoms; high fever, headache and stiff neck

hemophilia is more common in - ANSWER- males
Prenatal exposure to alcohol includes - ANSWER- ND-PAE, decreased brain
function, FAS
Connective vs muscle tissue disorders - ANSWER- Connective- RA,
Scleroderma, Lupus
Muscle - MS, Muscular dystrophy, Myasthenia Gravia
Describe Lupus - ANSWER- Inflammatory disorder characterized by joint pain
and butterfly rash
Describe Myasthenia Gravis - ANSWER- It is an autoimmune disorder where
antibodies attack own Ach receptors. This causes weakness of skeletal
muscles over the course of the day, along with ptosis, double vision, and
difficulty swallowing.
dermatitis - ANSWER- inflammation of the skin
eczema - ANSWER- noninfectious, inflammatory skin disease characterized
by redness, blisters, scabs, and itching
decubitus ulcer - ANSWER- sore caused by lying down for long periods of
time
Fungal infections - ANSWER- superficial, localized skin conditions or deep
tissue infections caused by exposure to spores
may or may not be transmitted
