Answer to Question 1

ANS: A
A chest X-ray is used most often to confirm the placement of the central venous pressure (CVP) catheter. Checking the centimeter mark may be deceiving because the catheter may be curling up inside a vessel. Ensuring the waveform is not always accurate because other values may be low enough to appear to be a CVP measurement. Due to arterial blood gas acid-base changes and oxygenation problems, the blood sample drawn may appear to be mixed venous, when in fact it is not.

Answer to Question 2

ANS: B
It usually takes several hours to days for an infection to develop, so infection would not occur during the insertion of the central venous pressure (CVP) catheter. Bleeding, pneumothorax, and vessel damage are all complications that may occur during the insertion of the catheter.
