Fluids and Sodium II (theilman)

NOT

hyponatremia is _______ about the sodium

hyponatremia

its a free water intoxication

5% dextrose

What fluid is equivalent to free water?

1000 mL

How much free water is in dextrose 5%?

500 mL

How much free water is in 0.45% NaCl?

0.

How much free water is in lactated ringers?

0

How much free water is in 0.9% NaCl?

-2,331

How much free water is in 3% NaCl?

lactated ringers

fluid destroyed to be similar to electrolytes in the blood

car wrecks with loss of blood

When do you use lactated ringers?

normal saline

-hyperkalemic

-metabolic acidosis

2 Na + 2K + Glucose + Urea

What is the equation for calculated osmolarity?

mEq

mmol is equal to _________

fluid restriction

What is the 1st line tx for chronic hyponatremia SIAD?

bolus 3% NaCl

What is the guidelines tx of choice for acute or symptomatic hyponatremia with severe symptoms?

continuous infusion 3% NaCl

What is the guidelines tx of choice for acute or symptomatic hyponatremia with moderate symptoms?

(Na IV - Na S) / (TBW + Volume IV)

What is the equation for a change in serum sodium concentration after an IV bolus?

osmotic demyelination syndrome

Complication of aggressive correction of HYPOnatremia can cause blood enphanomenon and death

NO

Can you give hypertonic saline in a small vein?

IV central venous catheter

How should you admin hypertonic saline?

increase sodium by no more than 0.5 mEq/L/hr

What is the goal of an increase in sodium with hypertonic saline?

thiazide induced hyponatremia

-thiazides block sodium reabsorption in distal tubules -> sodium lost

-decreased blood volume stimulates ADH release -> free water retained

correct sodium and increase circulating volume

What is the goal with thiazide induced hyponatremia?
