Question 1.

A. Assess the timing on the following strip.

a. Early inflation and early deflation
b. Late inflation and late deflation
c. Correct inflation and late deflation
d. Late inflation and early deflation
e. Correct timing

B. Why does the timing look different on the first beat on the strip?

	a.	Some one was changing the timing.
	b.	The amplitude of that R wave was too small to be recognized and the pump triggered on the T wave.
	c.	The patient is being paced.
	d.	The arterial line is the problem.
	e.	It was an ectopic beat.

Question 2.

Assess the timing on the following strip.

a. Late inflation and correct deflation
b. Early inflation and correct deflation
c. Early inflation and early deflation
d. Correct inflation and late deflation
e. Late inflation and early deflation

Question 3.

The following strip was recorded from a patient post CABG. He had atrial and ventricular temporary pacing wires inserted during surgery.

A. What is wrong with the pacemaker?

	a.	The connections to the atrial and ventricular wires are reversed so that the ventricles are being paced first then the atria.
	b.	The pacemaker is functioning correctly.
	c.	The pacer is not sensing appropriately.
	d.	The pacer is not capturing.
	e.	The patient is not paced at this time.

B. Would AV Pace be an appropriate trigger selection.

	a.	Yes.
	b.	No. The second pacer spike (the potential trigger event) is after the QRS complex so timing could be an issue.

Question 4.

Is this a timing or a triggering problem?

a. Timing problem
b. Trigger problem

Question 5.

You are getting intermittent GAS LEAKAGE alarms on the pump. There is no evidence of blood in the tubing and all the connections seem tight. You notice what appears to be water in the drive line tubing.

What is the problem?

a. Ectopic beats.
b. The pump is timed wrong.
c. There is a trigger problem
d. The water in the drive line tubing is slowing down gas transition.
e. It is raining.

Question 6.

The following patient is in Cardiogenic Shock. A 40cc IAB was inserted yesterday. It is in the correct position per CXR. He is 6'4" and 131.5kg. His HR is 146, CI is 1.3, PCWP is 28 and SVR is 433. He is on Dobutrex at 20mcg/kg/min, Primacor at 20mcg/kg/min, Dopamine at 15mcg/kg/min, Levophed at 101mcg/kg/min and Heparin at 1000u/hr.

Why is diastolic augmentation less than systole?

	a.	There is a timing error.
	b.	He is dry and needs more volume.
	c.	His cardiac status is so poor that an IABP cannot provide adequate support and a VAD should be considered.
	d.	The IABP is mal functioning.
	e.	The sun is shining and the patient would rather be outside.

Question 7.

A. Assess the timing on the following strip.

a. Late inflation and early deflation
b. Correct inflation and early deflation
c. Early inflation and late deflation
d. Late inflation and late deflation
e. Early inflation and early deflation

B. Which trigger do you think is selected?

a. R - Wave
b. Peaks
c. AV Pace
d. Internal
e. Arterial Pressure

Question 8.

What is wrong with the arterial pressure line on the following strip?

	a.	AP line is dampened and needs to be flushed.
	b.	Transducer needs to be zero'd.
	c.	The IAB is too high and the tip of the arterial line is being occluded as it hits up against the aortic arch.
	d.	Nothing.
	e.	There is air in the pressure tubing.

Question 9.

Assess the timing on the following strip.

a. Correct timing
b. Late inflation and correct deflation
c. Early inflation and late deflation
d. Late inflation and early deflation
e. Correct inflation and early deflation

Question 10.

Assess the timing on the following strip.

a. Correct timing
b. Early inflation and late deflation
c. Early inflation and early deflation
d. Correct inflation and early deflation
e. Late inflation and early deflation
