B) Puncture technique and sample acquisition

C) Storage and disposal of blood specimens and care of the puncture site

D) All the above

2) Indications for ABGs include:

A) Clinical presentation of normal ventilation, oxygenation, and acid-base status

B) Evaluate changes in therapy such as FiO2, applied PEEP, ventilator rate, or tidal volume changes

C) None of the above

D) A & B

3) If an ABG sample is contaminated with air:

A) The measured PO2 of the sample increases if the true value is less than 150 mmHg

B) The measured PO2 of the sample decreases if the true value is more than 150 mmHg

C) A & B

D) None of the above

4) The arterial blood can be obtained from several arteries, but the radial artery is usually chosen because of the:

A) Radial artery never causes puncture pain

B) Collateral blood flow to the hand via the ulnar artery
