A child has a radial arterial line in place. The nurse assesses the distal fingertips as cool and pale. Which action is most appropriate based on these assessment findings?
A.
Apply warm, moist heat.
B.
Disconnect the device.
C.
Elevate the extremity.
D.
Notify the provider.
ANS: D
An invasive device within an artery can disrupt arterial blood flow to the distal tissues. The nurse should notify the provider so the arterial line can be moved, or possibly discontinued. Warm, moist heat will not increase perfusion that is disrupted mechanically. Elevating the extremity will decrease perfusion further. The nurse should not disconnect the device.
