WGU Pathophysiology D236 questions and well stated answers
Describe how your body responds to an infection. - correct answer-T cells produce
cytokines, which stimulate B cells. B cells produce antibodies.
Identify role of DNA changes in congenital abnormalities. - correct answer-Mutations in
genes or chromosomal abnormalities
How does development disrupts congenital abnormalities? - correct answer-Alterations of
DNA
Describes factors that disrupt homeostasis and how disruptions affect wellbeing. - correct
answer-(ex) Fluid and electrolyte shifts can cause n/v or dysrhythmias.
Explain RAAS - correct 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 - correct answer-increased anion gap, decreased HCO3
How do kidneys compensate for alkalosis - correct answer-retain H and excrete HCO3
Untreated acidosis leads to an increase in which electrolyte? - correct answer-Potassium
West Nile Virus - correct answer-Transmitted through the bite of an infected mosquito.
Severe signs and symptoms; high fever, headache and stiff neck
,Lyme disease - correct answer-Tick-borne disease caused by the spirochete Borrelia
burgdorferi.
Erythema infectiosum - correct answer-a febrile upper respiratory illness in a child
followed by the sudden appearance of red, flushed cheeks, "fifth disease"

bifida
Trousseau's sign - correct answer-arm/carpal spasm associated with hypocalcemia
Cause and sign of spina bifida - correct answer-results from failure of neural tube to close.
sign - fluid filled sac on lower back.
hemophilia is more common in - correct answer-males
Prenatal exposure to alcohol includes - correct answer-ND-PAE, decreased brain function,
FAS
Connective vs muscle tissue disorders - correct answer-Connective- RA, Scleroderma,
Lupus
Muscle - MS, Muscular dystrophy, Myasthenia Gravia
Describe Lupus - correct answer-Inflammatory disorder characterized by joint pain and
butterfly rash
Describe Myasthenia Gravis - correct 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 - correct answer-inflammation of the skin
eczema - correct answer-noninfectious, inflammatory skin disease characterized by
redness, blisters, scabs, and itching
decubitus ulcer - correct answer-sore caused by lying down for long periods of time
Fungal infections - correct answer-superficial, localized skin conditions or deep tissue
infections caused by exposure to spores
may or may not be transmitted
benign neoplasm - correct answer-noncancerous growths, stationary, distinct borders
malignant neoplasm - correct answer-uncontrolled new tissue growth, irregular borders,
spreads
Osteoporosis - correct answer-The loss of bone mass often due to age, causing the bones
to become porous, brittle, and easily fractured.
osteomalacia - correct answer-disease marked by softening of the bone caused by
calcium and vitamin D deficiency
myoglobin - correct answer-red pigment that stores oxygen in muscle cells
Bursa - correct answer-fluid-filled sac that allows for easy movement of one part of a joint
over another
