Week 2 Acid Base And Shock

Question 1

The symbol used to indicate H+ ion concentration is

Answer 1

Ph

Question 2

Bases have what

Answer 2

Have lower concentration of H+ ions

Bases will take away or bind will H+ ions from a solution decreasing acidity

Question 3

What is the main buffer system

Answer 3

Carbonic acid/ bicarbonate system In the renal tubular fluid

Others are ammonia phosphate
Substances: protein hemoglobin

Question 4

Is a gas that forms carbonic acid when combined with water

Answer 4

Carbon dioxide

Question 5

The body maintain acid base balance by

Answer 5

Respiratory control of carbon dioxide
Buffers
Renal regulation of bicarbonate

Question 6

Hyperventations release what to decrease the risk of what

Answer 6

Co2

Acidosis

Question 7

Carbonic acid breaks into what

Answer 7

H20 & Co2

Through exhalation , slow shallow breaths increase extra cellular fluid activity

Question 8

S/S of acid base balance

Answer 8

Anxiety confusion seizure SOB

Question 9

COPD pts have what kind of levels and what is it due to ?

Answer 9

+co levels and normal ph that is due to renal compensation

Question 10

Hyperventilation cause respiratory?

Answer 10

Alkalosis

Question 11

With metabolic the body retains to much what or loses what

Answer 11

H+

Bicarbonate ions

Question 12

Metabolic acidosis leads to what because lungs try to compensate by getting rid of what therefore decreasing what and increasing what

Answer 12

Hyperventilation
CO2
PaCO2
ph

Question 13

What is the definition of shock

Answer 13

A syndrome characterized by inadequate tissue perfusion resulting in impaired cellular metabolism

Question 14

Hypovolemia shock occurs when

Answer 14

Blood volume has decreased resulting in decreased o2 and nutrients to tissue

Dehydration, 3rd spacing

Question 15

What are the 3 caused disorders of distributive shock

Answer 15

Anaphylaxis ,septic, neurogenic

Question 16

Anaphylaxis shock is a and does what

Answer 16

Severe allergic reaction

Leads to airway obstruction

Question 17

Septic shock is a and caused by

Answer 17

Systemic inflammatory response to sepsis caused by bacterial infections eschericha coli, staph

Question 18

Neurogenic shock is caused

Answer 18

After to the head or spinal cord resulting disruption to nerve resulting in vasodilation

Question 19

Obstructive shock is and caused by

Answer 19

Interference of circulation of blood In/out of the heart caused by cardiac tamponade , tension Pneumothorax
The actual heart muscle is unhealthy
Associated w/ CHF MI

Question 20

What are the stages of shock

Answer 20

Compensation.
Decompensation
Irreversible

Question 21

Compensation stage

Answer 21

B/p (initiating stimulus) increase HR TPR

Renin angiotensin activation

Question 22

Decompensation stage

Answer 22

Unresolved process
Failure of compensatory mechanism
Hypoxia decrease myocardial contractibility permeability capillary

Question 23

Irreversible stage

Answer 23

Decrease co
Irreversible tissue n organ damage
Death

Question 24

What is disruptive shock

Answer 24

Increase blood dilation , fluid pools in dependent areas , increase capillary permeability

Question 25

Acids have what

Answer 25

Degree of concentration of H+ ions in a solution
Higher the concentration of free H+ ions the more acidic
And some acidic substances readily real ease H+ ions
