MIDTERM EXAM: NR507 / NR 507 ADVANCED

PATHOPHYSIOLOGY (LATEST UPDATES

STUDY BUNDLE WITH COMPLETE SOLUTIONS) | 100%

CORRECT | GRADE A - CHAMBERLAIN

Glomerulonephritis .....ANSWER.....The glomerular-capillaries can

trap blood-borne Ab & Ag-Ab complexes

- Causes: PRIMARY: infection, drugs, toxins, vascular disorders,

ischemia, immunologic responses, free radicals. SECONDARY:

DM, CHF, HIV, Lupus




Triggering event (infection)- Ag-Ab complex formation &

deposition in glomerulus- Activation of complement system &

WBC infiltration- Glomerular injury & leakage-

Proteinuria/hematuria- edema, increase creat, azotemia, oliguria

OR

,Page 2 of 29


after glomerular injury & leakage- Coagulation cascade

activation & FIbrin deposition- Decreased capillary perfusion-

decreased GFR- edema, increase creat, azotemia, oliguria

S1 .....ANSWER.....-Closing of mitral and tricuspid valve

- Beginning of systole

S2 .....ANSWER.....- Closure of the aortic and pulmonic valve

- End of systole

Valvular stenosis .....ANSWER.....the valve orifice is constricted

and narrowed, impeding the forward flow of blood and

increasing the workload of the cardiac chamber proximal to the

diseased valve. Intraventricular or atrial pressure increases in the

chamber to overcome resistance to flow through the valve.

Increased pressure causes the myocardium to work harder,

causing myocardial hypertrophy.

Aortic stenosis .....ANSWER.....- LV hypertrophy
