Answer 5

critical value <4500 - late shock

>11000-infection

Question 6

shock Hgb

Answer 6

<12

- decrease blood loss

Question 7

shock Hct-3

Answer 7

<35%

• decrease blood loss
• increase dehydration and hemoconcentration

Question 8

ABG pH-2

Answer 8

<7.35- decrease late shock, metabolic acidosis due to lactic acidosis
>7.45- increase early dhock, respiratory alkalosis due to hyperventilation

Answer 10

<80 -decreased w hypoxemia, may indicate pulmonsry edema or ARDS

Question 11

ABG HCO3

Answer 11

<22- decreased in late shock, metabolic acidosis cuased by hypoxia
