Answer to Question 1

ANS: C
CVP assesses function of the heart's right side. It represents the amount of venous return and filling pressure of the right ventricle.

Answer to Question 2

ANS: A
Normal CVP readings range from 2 to 8 mm Hg and respiratory inspiration creates negative pressure. CVP may be monitored with a single-lumen or multilumen radiopaque catheter. A double- or triple-lumen Hickman or Broviac catheter is used most commonly.
