if the test is negative, evaluate the other hand or brachial site.
-
The hand has collateral blood flow when the hand flushes within 10-15 seconds.

All of the above.
Question 5

-
PaO2, PaCO2, CaO2, and PvO2
-
pH, PaCO2, PvO2, and HCO3
-
pH, PaCO2, HCO3, and BE
-
pH, BE, PaO2, and CaO2
Question 6
Question
Oxygen is mainly dissolved in the blood while a smaller portion is transported bound to Hgb.
Answer
- True
- False
Question 7
Question
What is the normal range for PaO2 in arterial blood?
Answer
-
80-180 mmHg
-
60-90 mmHg
-
80-100 mmHg
-
65-85 mmHg
Question 8
Question
What factors determine PaO2?
Answer
-
PB (760 mmHg)
-
age
-
FiO2
-
PAO2
-
all of the above
Question 9
Question
What happens to your PaO2 as you age over 60 years?
Answer
-
every year over 60 = drop of 1 mmHg
-
every year after 60 = gain of 1 mmHg
-
every year after 60 = drop of .5 mmHg
-
PaO2 won't change when you age over 60 years.
Question 10
Question

60-79 mmHg: mild
40-59 mmHg: moderate
<40 mmHg: severe

Answer
-
low pH
-
gas dissolving in blood
-
collapsed lung
-
V/Q mismatching
Question 12
Question
The normal value of oxygen saturation is 97% instead of 100% since the normal anatomic shunt is 3%.
Answer
- True
- False
Question 13
Question
The normal value of oxygen saturation is 97% instead of 100% because the normal anatomic shunt is 3%
Answer
- True
- False
Question 14
Question
True SaO2 can be determined only from a co-oximeter.
Answer
- True
- False
Question 15
Question
Identify the correct statements about 2,3 DPG.
I. found in leukocytes
II. Aids in reducing affinity of oxygen & releases it to the cells
III. Increases levels found in patients with anemia.
IV. Decreased levels found in fetal blood.
Answer
-
I
-
II and III
-
I, II, IV
-
II, III, IV
Question 16
Question
Describe how changes in PaO2 affect5 SaO2.
Answer
-
PaO2 changes over 80 mmHg = minimal changes in SaO2
-
PaO2 changes over 80 mmHg = significant changes in SaO2
-
PaO2 changes below 80 mmHg = minimal changes in SaO2.
-
PaO2 changes below 80 mmHg = significant changes in SaO2.
