The nurse is caring for a patient with a left subclavian central venous catheter (CVC) and a left radial arterial line. Which assessment finding by the nurse requires immediate action?
a. A dampened arterial line waveform
b. Numbness and tingling in the left hand
c. Slight bloody drainage at subclavian insertion site
d. Slight redness at subclavian insertion site
B
Numbness and tingling in the left hand, which is the location of an arterial catheter, indicates possible neurovascular compromise and requires immediate action. A dampened waveform can indicate problems with arterial line patency but is not an emergent situation. Slight bloody drainage at the subclavian insertion site is not an unusual finding. Slight redness at the insertion site, while of concern, does not require immediate action.
