Answer 4

*

Question 5

Normal PH is…

Answer 5

7.35-7.45

Question 6

Homeostasis maintains

Answer 6

a delicate balance of acids and bases (alkaline).

Question 7

PH of less than 7.35 =

Answer 7

Acidosis

Question 8

Acidosis can be caused by…

Answer 8

too much acid or too little base in bloodstream.

Question 9

PH of greater than 7.45 =

Answer 9

Alkalosis

Question 10

Alkalosis can be caused by…

Answer 10

too much alkaline (base) or too little acid in the bloodstream.

Question 11

What does Carbon Dioxide (CO2) create with combined with water?

Answer 11

Carbonic Acid

Question 12

Carbon Dioxide is the ___________ evaluator.

Answer 12

Respiratory

Question 13

Normal Partial Pressure exerted by PaCO2 is…

Answer 13

35-45

Question 14

As the carbonic acid levels in the blood raise, so does the acidity levels and the PH Lowers.

Answer 14

*

Question 15

Bicarbonate is the _________ evaluator.

Answer 15

Metabolic

Question 16

When bicarb levels increase the PH rises and ________________ ______________ develops.

Answer 16

Metabolic alkalosis

Question 17

Metabolic Alkalosis can be caused by

Answer 17

Prolong periods of vomiting or use of diuretics (emesis and urine are acidic).

Question 18

Decreasing levels of bicarb causes PH to drop and leads to __________ ________.

Answer 18

Metabolic Acidosis

Question 19

Metabolic acidosis can result from

Answer 19

diarrhea or renal disease.

Question 20

Alkalosis vs Acidosis

Respiratory = Opposite
Alkalosis: PH is up, PCO2 is down
Acidosis: PH is down, PCO2 is up

(PCO2 = the partial pressure of carbon dioxide)

Answer 20

*

Question 21

Alkalosis vs Acidosis

Metabolic = Equal
Alkalosis: PH is up, HCO3 is up
Acidosis: PH is down, HCO3 is down

(HCO3 = Bicarbonate)

Answer 21

*

Question 22

ABG = Arterial Blood Gases what do they do

Answer 22

Measure oxygenation and carbon dioxide levels

Question 23

Assess ABGs with…

Answer 23

Radial artery, sometimes femoral. Can use aterial line if in place.

Question 24

ABGs are drawn by

Answer 24

assessing the artery, drawing blood into a hepranized syringe, holding pressure for 5 mins following procedure.
