Q

The ventricular walls are thicker than the atrial walls. Why would ventricular walls be thicker?

A

The Ventricles have a greater workload than the atria. They have to push blood out with great resistance, so they have to work harder. Because of this, they have thicker walls.

-Check the patients’ allergies

-Check patients kidney function

-Tell the patient about heat flashes as the catheter enters their chest.

-NPO 8-12 hours prior to the procedure

Q

Post-procedure of Cardiac Catheterization/Angiography involves putting pressure over the insertion site.

If the insertion was on the Radial artery, you want to apply pressure on it for “X” hours.

If the insertion was Femoral, you need to apply manual pressure for “X” minutes.

A Gel-patch will be typically applied to an insertion site for “X” minutes but will sometimes be left on for “X” hours.

A

Radial Artery insertion requires pressure for “2 hours.”

Femoral insertion requires pressure for 30 minutes.

Gel-patch typically stays on for 10 minutes, but will sometimes be left on for 24 hours.

97
Q

What should a nurse be assessing post-op in a patient that underwent a Cardiac Catheterization/Angiography?

A

-Check pulses
-Look for swelling and bruising.
(Some bruising is expected, but not excessive amounts.)

98
Q

If an ECG fails to evaluate AV nodes, or to assess for dysrhythmias, what would be the next diagnostic test used to assess for dysrhythmias, electrical cells firing, and AV node functioning?

a.) Electrophysiology
b.) Electroencephalography
c.) CT-scan
d.) Fluoroscopy

A

a.) Electrophysiology would be used to evaluate AV node function and to check for dysrhythmias if an ECG failed to do so.

99
Q

A nurse is educating a patient on proper procedure for an electrophysiology test. One of the roles of the nurse is to ensure the patient understands that there is an NPO order before the test that lasts for:

a.) 1-3 hours
b.) 4-6 hours
c.) 6-8 hours
d.) 12 hours
e.) 24 hours

A

c.) A patient should follow an NPO order of 6-8 hours before an Electrophysiology test.

100
Q

Cardiac mapping is a method used in Electrophysiology tests. From what you know about Electrophysiology tests and what they are for, what can you assume “Cardiac Mapping” is used for?

A

Cardiac mapping is used to locate arrythmias, show electrical cells firing (or not) and finding the AV and SA nodes.
