1

What is the normal value for:
pH

7.4
(7.35-7.45)

2

What is the normal value for:
PaCO2

40 mm hg
(35-45)

3

What is the normal value for:
PaO2

97 mm Hg
(80-100)

4

What is the normal value for:
HCO3-

24 mEq/L
(22-26)

5

What pH level indicates acidosis?

< 7.4

6

What pH level indicates alkalosis?

> 7.4

7

What ABG values indicate Respiratory Acidosis?

HIGH PaCO2, LOW pH
- PaCO2 > 45 mm Hg
- pH < 7.4

*Respiratory = high and low are OPPOSITES direction

8

What ABG values indicate Respiratory Alkalosis?

LOW PaCO2, HIGH pH
- PaCO2 < 45 mm Hg
- pH > 7.4

*Respiratory = high and low are OPPOSITES direction

9

What ABG values indicate Metabolic Alkalosis?

HIGH HCO3-, HIGH pH
- HCO3- > 24 mm Hg
- pH > 7.4

*Metabolic = high and low are SAME direction

10

What ABG values indicate Metabolic Acidosis?

LOW HCO3-, LOW pH
- HCO3- < 24 mm Hg
- pH < 7.4

*Metabolic = high and low are SAME direction

11

What is the normal value for:
Hematocrit

3.5-.45

12

What is the normal value for:
Hemoglobin

12-16

13

What is the normal value for:
Total Cholesterol

<200 mg/dL

14

What is the normal value for:
LDL Cholesterol

< 100 mg/dL

15

What is the normal value for:
HDL Cholesterol

> 40 mg/dL
(> or = 60 mg/dL is high and good!)

16

What is the normal value for:
Tryglyceride

< 150 mg/dL

17

What do Alpha Adrenergic Antagonist Agents do?

- Reduce peripheral vascular tone
- Dilate arterioles and veins
- Dec BP

18

What do Angiotensin-Converting Enzyme (ACE) Inhibitors do?

Dec BP and afterload

19

What do Angiotensin II Receptor Antagonist Agents do?

- Limit vasoconstriction
- Stimulate vascular tissue

20

What do Anticoagulant Agents do?

Inhibit platelet aggregation and thrombus formation

21

What do Antihyperlipidemia Agents (Stains) do?

- Inhibit enzyme action in cholesterol synthesis
- Break down low density lipoproteins
- Dec trigylceride
- Inc HDL

22

What do Antithrombotic (Antiplatelet) Agents do?

Inhibit clot formation

23

What do Beta Blockers do?

- Dec myocardial oxygen demand
- Dec HR and contractility

24

What do Calcium Channel Blocker Agents do?

- Dec myocardial contraction
- Dec vasodilation
- Dec O2 demand of heart

25

What do Diuretic Agents do?

Inc excretion of sodium and urine

26

What do Nitrates do?

Dec ischemia through (muscle relaxation and dilation of peripheral vessels)

27

What do Positive Inotropic Agents do?

Inc force & velocity of contraction

28

What do Thrombolytic Agents do?

Break down clots

29
