EMS 105 EXAM 3 QUESTIONS WITH 100%
CORRECT ANSWERS.
1) Normal cellular metabolism can be defined as:
A) Oxygenated
B) Aerobic
C) Glycolytic
D) Anaerobic
B
2) When cells undergo normal metabolism in the body, which byproduct(s) is (are)
produced?
A) Heat, carbon dioxide, and water
B) Lactic acid
C) Protein, carbon dioxide, and water
D) Adenosine monophosphate
A
3) Under normal circumstances, carbon dioxide is excreted from the body through the:
A) Kidneys
B) Urinary tract
C) Lungs
D) Sweat ducts
C
4) The patient in anaerobic metabolism is deficient in/of:
A) Glucose (sugar)
B) Protein
C) Lactic acid
D) Oxygen
D
,5) 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
B) Have too much adenosine triphosphate to function properly
C) Are producing elevated quantities of carbon dioxide (CO2) as a result of aerobic
metabolism
D) Cannot make any energy in the form of ATP due to a lack of glucose
A
6) 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) High-concentration oxygen through a nonrebreather face mask
B) Administration of one tube of oral glucose by the EMT
C) Positive pressure ventilation with supplemental oxygen
D) Insertion of a nasal airway and delivery of oxygen through a nasal cannula
C
7) What happens after a cell in anaerobic metabolism breaks down glucose and creates
energy in the form of adenosine triphosphate (ATP)?
A) Oxygen and water are created
B) Lactic acid is formed
C) Carbon dioxide and water are formed
D) Electrolytes in the cell become balanced
B
8) For cells to undergo the process of aerobic metabolism, the cells require:
A) Water and oxygen
B) Sugar (glucose) and protein
C) Adenosine triphosphate (ATP) and lactic acid
D) Oxygen and glucose
, D
9) Failure of the sodium-potassium pump can result in:
A) Accumulation of acidic wastes
B) Excess amounts of sodium outside the cell
C) Large amounts of potassium inside the cell
D) Cellular damage, swelling, and rupture
D
10) Perfusion is best described as:
A) Availability of oxygen in the lungs for movement into the blood
B) An adequate number of white blood cells to carry oxygen to the cells
C) Delivery of essential products and nutrients to the cell for its use
D) Exchange of oxygen and carbon dioxide between the lungs and blood
C
11) A patient is hemorrhaging internally within his colon, which in turn is impairing
perfusion to the cells of his body. Aside from the bleeding, the patient has no other
problems. In this scenario, the problem impairing adequate perfusion would be:
A) Decreased blood volume
B) Inability to get oxygen to the alveoli
C) Poor myocardial pump function
D) Inadequate ventilation to eliminate carbon dioxide
A
12) What is required for normal perfusion to occur?
A) Airway patency, proper amounts of carbon dioxide, and adequate glucose levels
B) Adequate breathing, sufficient numbers of red blood cells, and sufficient heart function
C) Intact breathing, an ample number of red blood cells, and body temperature of 98.6°F
D) Patent airway, sufficient breathing, high amounts of glucose, and good heart function
B
