WGU Pathophysiology D236 Exam 2023 With verified Solutions

1. Describe how your body responds to an infection.: T cells produce cy- tokines, which stimulate B cells. B cells produce antibodies. 2. Identify role of DNA changes in congenital abnormalities.: Mutations in genes or chromosomal abnormalities 3. How does development disrupts congenital abnormalities?: Alterations of DNA 4. Describes factors that disrupt homeostasis and how disruptions affect wellbeing.: (ex) Fluid and electrolyte shifts can cause n/v or dysrhythmias. 5. Explain RAAS: Renin-angiotensin-aldosterone system 1. Reduce blood flow causes kidneys to release renin > produce angiotensin I > converts angiotensin I to angiotensin II > vasoconstric- tion > release aldosterone > kidneys conserve sodium and water > Result less water lost in urine and blood pressure maintained. 6. DKA: increased anion gap, decreased HCO3 7. How do kidneys compensate for alkalosis: retain H and excrete HCO3 8. Untreated acidosis leads to an increase in which electrolyte?: Potassium 9. West Nile Virus: Transmitted through the bite of an infected mosquito. Severe signs and symptoms; high fever, headache and stiff neck 10. Lyme disease: Tick-borne disease caused by the spirochete Borrelia burgdor- feri. 11.

Prenatal exposure to alcohol includes: ND-PAE, decreased brain function, FAS 17. Connective vs muscle tissue disorders: Connective- RA, Scleroderma, Lu- pus Muscle - MS, Muscular dystrophy, Myasthenia Gravia 18. Describe Lupus: Inflammatory disorder characterized by joint pain and butter- fly rash 19. 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. 20. dermatitis: inflammation of the skin 21. eczema: noninfectious, inflammatory skin disease characterized by redness, blisters, scabs, and itching 22. decubitus ulcer: sore caused by lying down for long periods of time 23. Fungal infections: superficial, localized skin conditions or deep tissue infec- tions caused by exposure to spores may or may not be transmitted 24. benign neoplasm: noncancerous growths, stationary, distinct borders 25. malignant neoplasm: uncontrolled new tissue growth, irregular borders, spreads 26. Osteoporosis: The loss of bone mass often due to age, causing the bones to become porous, brittle, and easily fractured. 27. osteomalacia: disease marked by softening of the bone caused by calcium and vitamin D deficiency 28. myoglobin: red pigment that stores oxygen in muscle cells 29. Bursa: fluid-filled sac that allows for easy movement of one part of a joint over another
