WGU Pathophysiology D236 EXAM Questions &
Answers, Well Elaborated Already Verified Test
Verified solutions 2026
Describe how your body responds to an infection. - T cells produce cytokines, which stimulate B
cells. B cells produce antibodies.
Identify role of DNA changes in congenital abnormalities. - Mutations in genes or chromosomal
abnormalities
How does development disrupts congenital abnormalities? - Alterations of DNA
Describes factors that disrupt homeostasis and how disruptions affect wellbeing. - (ex) Fluid and
electrolyte shifts can cause n/v or dysrhythmias.
Explain RAAS - 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 - increased anion gap, decreased HCO3
How do kidneys compensate for alkalosis - retain H and excrete HCO3
Untreated acidosis leads to an increase in which electrolyte? - Potassium
West Nile Virus - Transmitted through the bite of an infected mosquito. Severe signs and
symptoms; high fever, headache and stiff neck
,Lyme disease - Tick-borne disease caused by the spirochete Borrelia burgdorferi.
Erythema infectiosum - a febrile upper respiratory illness in a child followed by the sudden
appearance of red, flushed cheeks, "fifth disease"
Obesity ad diabetes are risk factors for having a child with _____. - Spina bifida
Trousseau's sign - arm/carpal spasm associated with hypocalcemia
Cause and sign of spina bifida - results from failure of neural tube to close. sign - fluid filled sac
on lower back.
hemophilia is more common in - males
Prenatal exposure to alcohol includes - ND-PAE, decreased brain function, FAS
Connective vs muscle tissue disorders - Connective- RA, Scleroderma, Lupus
Muscle - MS, Muscular dystrophy, Myasthenia Gravia
Describe Lupus - Inflammatory disorder characterized by joint pain and butterfly rash
Describe Myasthenia Gravis - 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 - inflammation of the skin
, eczema - noninfectious, inflammatory skin disease characterized by redness, blisters, scabs, and
itching
decubitus ulcer - sore caused by lying down for long periods of time
Fungal infections - superficial, localized skin conditions or deep tissue infections caused by
exposure to spores
may or may not be transmitted
benign neoplasm - noncancerous growths, stationary, distinct borders
malignant neoplasm - uncontrolled new tissue growth, irregular borders, spreads
Osteoporosis - The loss of bone mass often due to age, causing the bones to become porous,
brittle, and easily fractured.
osteomalacia - disease marked by softening of the bone caused by calcium and vitamin D
deficiency
myoglobin - red pigment that stores oxygen in muscle cells
Bursa - fluid-filled sac that allows for easy movement of one part of a joint over another
Rickets - a vitamin D deficiency in children, resulting in soft bones
