Chapter 11 Egans Test

Enter the letter for the matching Answer
incorrect
1.
Alveolar partial pressure of carbon dioxide (PACO2)
incorrect
2.
IN theory V/Q imbalance should cause a rise in PACO2. However many patients who are hypoxemic because of a V/Q imbalance have a low or normal PaCO2. What does this suggest?
incorrect
3.
What does impaired CO2 removal by the lungs cause?
incorrect
4.
Alveolar capillary membrane
incorrect
5.
Gas movement between lungs and tissues occure by?
incorrect
6.
A decrease in RR is less common but may be present with respiratory center depression as in?
incorrect
7.
What is the alveolar air equation formula?
incorrect
8.
How to find the total oxygen content of blood?
incorrect
9.
What 3 things can result from ishemia?
incorrect
10.
What is the diffusion gradient for oxygen?
incorrect
11.
In pulmonary diffusion PvCO2 is how many mm Hg?
incorrect
12.
Hypoxia
incorrect
13.
Acidosis does what to 2,3-DPG?
incorrect
14.
What is an example of dysoxia?
incorrect
15.
Increased 2,3 DPG concentrations shift the HbO2 curve to the? Promoting what?
incorrect
16.
What are some factors other than HbO2 curve that affect oxygen unloading and loading?
incorrect
17.
Any disorder that lowers alveolar ventilation relative to metabolic need impairs?
incorrect
18.
Does carbon dioxide diffuse faster or slower across the alveolar-capillary membrane than oxygen? Why?
incorrect
19.
Conditions that cause an decrease in Hb affinity for oxygen cause a shift to the?
incorrect
20.
In pulmonary diffusion PvO2 is how many mm HG?
A.
anaerobic metabolism, metabolic acidosis, eventual death of tissue
B.
normal atomospheric inspired partial pressure (PIO2) of 159 mm Hg to a low point of 40 mm Hg or less in the capillaries
C.
cyanide poisoning. It disrupts intracellular system preventing cellular use of oxygen
D.
varies directly with the body's production of CO2 and inversely alveolar ventilation
E.
blood pH, body temp, erythrocyte concentration of certain organic phosphates, variations in the structure of Hb, chemical combinations of Hb with substances other than O2
F.
46 mm Hg
G.
right. Oxygen unloading
H.
PAO2= FIO2*(PB -47)-(PACO2/0.8)
I.
when oxygen delivery falls short of cellular needs
J.
V/Q imbalances have a greater effect on oxygenation than on carbon dioxide removal.
K.
the barrier to gaseous diffusion in the lung
L.
hypercapnia and respiratory acidosis
M.
40 mm Hg
N.
20 times faster. Because of its much higher solubility in the plasma.
O.
right.
P.
lowers the level of DPG and a greater affinity of Hb for O2.
Q.
total oxygen content of bloo equals the sum of that dissolved and chemically combined with Hb
R.
carbon dioxide removal
S.
simple diffusion
T.
drug overdose
Type the Answer that corresponds to the displayed Question.

What is the difference between the arterial and venous oxygen contents?
incorrect
22.
What factor is used to convert VCO2 from STPD to BTPS?
incorrect
23.
Neural control mechanisms and increased work of breathing prevent decreases in PaCO2 much below?
incorrect
24.
In order for oxygen to diffuse into and out of the lung and tissues, O2 and carbon dioxide must move through....
incorrect
25.
At the tissues, temperature changes are directly related to?
incorrect
26.
A low pH shifts a curve to the?
incorrect
27.
Normal range for cardiac output
incorrect
28.
Carbon dioxide hasa the capacity to chemically cobine with free amino groups of protein molecules forming a?

29.
process of getting O2 into the body for tissue utilization and removal of CO2 into the atmosphere
incorrect
30.
SaO2=[HbO2 / Total Hb]*100
