Q

what happens to the vessel when lesion at site?

A

vasoconstriction distal
vasodilation proximal

increased WBC to localized area of injury

vasodilation caused by prostacyclins and PGE2 to mobilize WBC to the site of injury

vasoconstriction caused by thromboxane and leukotrienes to prevent spread of infection to systemic

Q

What is anion gap?

A

normal 8-16
measure of plasma anions chloride and bicarb

lactic acid using up bicarb

Na - Cl + bicarb

anion gap =ketoacidosis, lactic acidosis, renal failure
non anion gap= mudd butt, renal tube acidosis, renal failure

Q

what ion inhibits presynaptic ach release and potentiates NDNMB?

how much do you reduce the dose?

A

hypermagnesemia

1/3 to 1/2

17
Q

the major extracellular cation responsible for osmotic pressure that maintains ECF volume?

A

sodium

18
Q

serum osmol equation?

A

2 times sodium plus glucose divided by 18

19
Q

when ECF volume increases the kidneys increase sodium excretion. What is the MOA?

A

ANP promotes sodium excretion
BNP promotes sodium excretion
Renal vasodilation promotes NaCl and H2O excretion

20
Q

when ECF volume decreases the kidneys increase sodium retention. What is the MOA?

A

RAAS promotes Na retention

B1 kidney, renin, granular cells, sodium reten

Whats your name
Let me talk to you

A 
Let me buy you a drink
