1
Q

Normal cellular metabolism can be defined as ?

A

Aerobic

2
Q

When cells undergo normal metabolism in the body, which byproduct(s) is/are formed?

A

Heat, carbon dioxide, water

3
Q

Under normal circumstances, carbon dioxide is excreted from the body through the ?

A

Lungs

4
Q

The patient in anaerobic metabolism is deficient in/of

A

Oxygen

5
Q

A patient’s brain cells are undergoing anaerobic metabolism. As a result, those cells…

A

Are becoming dysfunctional in an environment that is increasingly acidic

6
Q

A patient’s lungs are full of fluid and cannot transfer oxygen to the blood. As a result, she is undergoing anaerobic metabolism. She has a decreased level of consciousness with a patent upper airway and inadequate respirations. Her pulse is rapid and weak. Which prehospital treatment would best address this situation ?

A) positive-pressure ventilation w/ supplemental oxygen

B) insertion of a nasal airway and delivery of oxygen through a nasal cánula.

C) High concentration oxygen through a nonrebreather face mask

D) administration of one tube of oral glucose by the EMT

A

A) positive-pressure ventilation w/ supplemental oxygen

7
Q

What happens after a cell in anaerobic metabolism breaks down glucose and creates energy in the form of adenosine triphosphate (ATP) ?

A

Lactic acid is formed

8
Q

For cells to undergo the process of aerobic metabolism, the cells require…?

A

Oxygen and Glucose

9
Q

Failure of the sodium-potassium pump can result in ?

A

Cellular damage, swelling, and rupture

10
Q

Perfusion is best described as:

A

Delivery of essential products and nutrients to the cell for its use

11
Q

A patient is hemorrhaging internally within his colon, which in turn is affecting his perfusion to the cells of his body. Aside from the bleeding, the patient has no other problems. In this scenario, the problem preventing adequate perfusion would be??

A

Decreased blood volume

12
Q

What is required for normal perfusion to occur?

A

Adequate breathing, sufficient number of red blood cells and sufficient heart function.
