WGU D236 Pathophysiology Exam Questions With 100%
Correct Answers | Verified | Latest Update 2026
How does your body respond to infection?
T-cells produce cytokines -> cytokines stimulate B cells -> B cells
produce antibodies
Role of DNA changes in congenital abnormalities
DNA changes can cause congenital abnormalities (Spina Bifida and ND-PAE)
RAAS (renin-angiotensin-aldosterone system)
reduced blood flow -> cause kidneys to release renin -> production of angiotensin I
-> angiotensin I converts to angiotensin II -> angiotensin II causes vasoconstriction
-> aldosterone is released -> Na+ and H2O are conserved -> reduced urinary
output which maintains fluid volume which helps maintain BP
DKA
- Increased anion gap
- Decreased HCO3
How do kidneys compensate for alkalosis?
- Retain H+
- Excrete HCO3
Untreated acidosis leads to an increase in which electrolyte?
Potassium
West Nile Virus
- Transmitted through the bite of an infected mosquito.
- Mild S/S: fever, headache and body ache, nausea and vomiting, rash to chest,
stomach, and back, neck soreness, swollen lymph gland
, - Severe S/S: high fever, headache and stiff
neck, confusion/disorientation, coma, seizures, muscle
weakness, numbness, paralysis, vision loss
Lyme disease
- Tick-borne disease
- Spirochete Borrelia burgdorferi
Erythema infectiosum
- Febrile URI in children
- Sudden onset of red/flushed cheeks
- Fifth Dz
Risk Factors for Spina Bifida
- Obesity
- Diabetes
- Maternal malnutrition (insufficient Folic Acid)
- Medications (Valproic Acid)
Troussea's sign
- Carpal Spasm induced by inflating a blood pressure cuff above the systolic
pressure for a few minutes
- Associated with hypocalcemia
Causes of Spina Bifida
- Exposure to alcohol
- Genetic predisposition/ethnicity
- Lack of folic acid
- Smoking
ND-PAE (neurobehavioral disorder associated with prenatal alcohol exposure)
