,C. Prone position
D. Supine position
Answer>>

position.

Question>> 3
While performing ACLS on a patient who is in complete
cardiac arrest, the physician orders arterial blood gas
analysis. The RT is unable to palpate a radial pule. BP is 25/5
mm Hg. The RT should:
A. Obtain blood from the femoral artery
B. Use venous blood for the blood gas analysis
C. Perform an Allen's test
D. Attempt a brachial artery puncture
Answer>>
A.

control ventilation. Which of the following positions would
be most helpful in promoting effective gas distribution and
preventing ventilator acquired pneumonia?

C. semi-Fowler's position

,D. Trendelenburg
Answer>>
C
For a patient who is in bed, or is not ambulatory, semi-
Fowler's position is the best position for gas distribution in
the lungs and therefore is most helpful in preventing
ventilator acquired pneumonia or VAP.

Question>> 5
A 38-year-old male presents in the emergency department
(ED) complaining of frequent vomiting. The following
laboratory data is available: Arterial blood gases pH 7.55
PaCO2 42 torrPaO2 85 torrHCO3- 31 mEq/LBE +7
mEq/LFIO2 0.21K+ 3.0
mEq/LCl- 95 mEq/LNa+ 135 mEq/L
Which of the following should the respiratory therapist
recommend?
A. administer NaCL
B. administer NaHCO3-
C. administer KCL
D. administer volume-expanding fluids
Answer>>
C.
This patient has a CO2 of 42 mmHg, which suggests
adequate ventilation. However, the high pH is associated
with alkalosis. Because the CO2 is normal, the cause of the
alkalosis must be metabolic in nature. One treatment for
metabolic alkalosis is to administer potassium chloride or
KCl.
