ACID BASE BLUH

Question 1

Total body water makes up what % of total body weight in healthy non-obese animals?

Answer 1

60%

Question 2

Thirst and renal output are controlled by what?

Answer 2

effective circulating volume

Question 3

What is ECV influenced by?

Answer 3

Blood volume, arterial blood pressure, arterial resistance, and delivery of blood to volume receptors.

Question 4

What is the best indicator for increased total body water?

Answer 4

Body weight dummy

Question 5

What is the difference between osmolality and osmolarity?

Answer 5

Osmolality: # of solute particles / unit weight of solution
Osmolarity: # of solute particles / unit volume of solution

Question 6

What contributes to osmolality?

Answer 6

2(Na+K) + (Glucose/18) + (BUN/2.8)

Question 7

What is the difference between osmolality and tonicity?

Answer 7

Tonicity does not include BUN in the equation

Question 8

T/F Urea is an effective osmole

Answer 8

FALSE; it freely crosses the ECF and ICF. Does not contribute to tonicity.

Question 9

What causes a decreased osmolar gap?

Answer 9

You jack ass. Does not occur.

Question 10

What causes hyperosmolality?

Answer 10

Hypernatremia; increased BUN and glucose may cause this

Question 11

T/F PCO2 = TCO2

Answer 11

FALSE; PCO2 is from blood gas, while TCO2 is from chemistry

Question 14

T/F PO2 reflects the total O2 carried in the blood

Answer 14

FALSE; Most O2 is bound to Hgb

Question 15

A low PO2 =

Answer 15

hypoxemia

Question 16

PCO2 is what? What does it measure?

Answer 16

Partial pressure of CO2
