Arterial Lines

Which of the following is not an indication for an arterial line?

• Hypotension

• ABG for a one-time draw

• Alternative IABP trigger

• Patient is on multiple vasoactive meds

Phlebostatic Axis

• 4th ICS, midaxillary line

• 3rd ICS, midaxillary line

• 4th ICS, anterior axillary line

• 3rd ICS, anterior axillary line

The most common cause of error in art line monitoring

• Accidental introduction of air into line

• Incorrect arterial line placement

• Failure to draw enough blood into the vamp

• Incorrect transducer level

What can a slurred dicrotic notch represent?

• Aortic valve closure

• Aortic valve stenosis

• Mitral valve stenosis

• Mitral valve closure

According to the Art Line Rule of 3s, at what rate should fluid be delivered into the line?

• 30ml/hr

• 3ml/min

• 3ml/hr

• 300ml/hr

How much pressure should your arterial line pressure bag be under?

• 100mmHg

• 200mmHg

• 300mmHg

• 400mmHg

You've just done a square wave test after zeroing your transducer. You should expect to see no more than ___ oscillations before returning to baseline.

• 2

• 3

• 4

• 5

You suspect an issue with your transducer. The DBP is being overestimated and the SBP is being underestimated. This indicates:

• Overdamping

• Underdamping

• Loss of Zero

• Noncompliant Tubing

An obstruction to the transducer will cause:

• Overestimated blood pressures

• Underestimated blood pressures

• Overestimated DBP and ununderestimated SBP

• Underestimated DBP and overestimated SBP

You notice the transducer is below the phlebostatic axis. What effect is this likely to have?

• Overdamping; the DBP will be overestimated and the SBP will be underestimated

• Overdamping: the DBP will be underestimated and the SBP will be overestimated

• Underdamping: the DBP will be overestimated and the SBP will be underestimated

• Underdamping: the DBP will be underestimated and the SBP will be overestimated
