accurate detailed solutions || ||
Which of the following statements is true concerning capillary blood gas sampling versus
|| || || || || || || || || || || || ||
arterial blood gas analysis? || || ||
A.
||
Capillary pH will be lower than the arterial pH || || || || || || || ||
B.
||
Capillary PO2 will be lower than the arterial PO2 || || || || || || || ||
C.
||
Capillary PCO2 will be higher than the arterial PCO2 || || || || || || || ||
D.
||
Capillary HCO3 - will be higher than the arterial HCO3- - ✔✔Capillary PO2 will be lower
|| || || || || || || || || || || || || || || ||
than the arterial PO2

The functional residual capacity measured for a patient using the helium dilution technique
|| || || || || || || || || || || ||
is 3.0 L. The same patient is then tested in a body box and the result is 4.5 L. Which of the
|| || || || || || || || || || || || || || || || || || || || || || ||
following would account for the difference? || || || || ||
A.The patient has significant non-ventilated lung volume.
|| || || || || ||
B.There was a leak during the helium dilution procedure.
|| || || || || || || ||
C.The patient was switched in at an incorrect lung volume.
|| || || || || || || || ||
D.The patient did not pant correctly during the procedure. - ✔✔A.The patient has
|| || || || || || || || || || || || ||
significant non-ventilated lung volume. || || ||
- nonventilated lung volume- airtrapping
|| || || ||
, Calculate the approximate PAO2 for a healthy patient breathing 30% oxygen at sea level.
|| || || || || || || || || || || || ||
A.100 - 115 torr || || ||
B.120 - 135 torr || || ||
C.155 - 170 torr || || ||
D.210 - 225 torr - ✔✔C.155 - 170 torr
|| || || || || || || ||
Prior to performing spirometry, the respiratory therapist calibrates the spirometer using a
|| || || || || || || || || || || ||
3.0 L super syringe. The therapist records three volumes at 2.80 L, 2.80 L, 2.79 L. Based
|| || || || || || || || || || || || || || || || ||
upon the information obtained, the therapist should conclude that the spirometer is
|| || || || || || || || || || ||
|| 1. precise.
||
|| 2. accurate.
||
|| 3. free from artifacts.
|| || ||
|| 4. leaking.
||
A.
1 and 3 only
|| || ||
B.
1 and 4 only
|| || ||
C. ||
2 and 3 only
|| || ||
D. ||
2 and 4 only - ✔✔1 and 4 only
|| || || || || || || ||
The respiratory therapist observes a patient in the ICU and notes that there is an increase in
|| || || || || || || || || || || || || || || ||
the patient's respiratory rate and depth of breathing. The therapist also notices that the
|| || || || || || || || || || || || || || ||
patient's breath has a fruit-like aroma. This would most likely be associated with
|| || || || || || || || || || || ||
A.
