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

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