Question

1.  Which of the following choices would cause the greatest increase in GFR?  Show your work.

            a.  10% increase in glomerular blood hydrostatic pressure (BHP)

            b.  50% decrease in capsular hydrostatic pressure (CHP)

            c.  50 decrease in blood colloid osmotic pressure (BCOP)

            d.  50% constriction of both the afferent and efferent arterioles

2.

1. For each of the cases below, indicate whether there is an alkalosis or acidosis present.
2. For each case, indicate whether the cause is metabolic or respiratory.
3. For each case, indicate whether the condition is being compensated.
4. Fore each case, list 1 possible cause for the condition.

Case #1:

pH = 7.63

PCO2 = 11 mm Hg

HCO3- = 19.5 mEq/L

Case #2:

pH = 7.22

PCO2 = 30 mm Hg

HCO3- = 12.0 mEq/L

Answer 1

1). C). 50% decrease in bcop.

2). Case 1 : partially compensated , respiratory alkalosis. Eg : panic attacks .

case 2 : partially compensated metabolic acidosis . Eg : lactic acidosis .
