WGU D236 Pathophysiology Exam (Latest 2023/ 2024
Update) Questions and Verified Answers| Grade A+
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"
Obesity ad diabetes are risk factors for having a child with _____. - Correct Answer ✔✔ - Spina 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
