The client has just been started on disopyramide (Norpace). The client asks why they are getting so many ECGs. Which is the nurse's best response?

1. The prescriber believes these are necessary.
2. The medication can cause new dysrhythmias to occur.
3. Insurance companies are suggesting this helps with treatment.
4. I will call the prescriber for clarification.

Question 2

A client asks the nurse about having a pacemaker placed in the AV node. Which statement by the nurse best describes a pacemaker placed in the AV node?

1. This pacemaker will generate an electrical signal from the atria to the ventricles.
2. This pacemaker will generate an electrical signal from the sinoatrial node.
3. This pacemaker will generate a mechanical disruption of force to the entire heart.
4. This pacemaker will generate a force of contraction from the ventricles to the atria.

Answer to Question 1

2

Rationale 1:The prescriber is aware of the potential of new dysrhythmias or worsen existing ones and that is why the client is having repeated ECG.
Rationale 2:Sodium channel blockers have the potential to cause new dysrhythmias or worsen existing ones. Frequent ECGs should be obtained to identify them.
Rationale 3:Insurance companies do not suggest treatment plans.
Rationale 4:Calling the prescriber for clarification is incorrect.

Global Rationale: All the sodium channel blockers have the potential to cause new dysrhythmias or worsen existing ones; thus, frequent ECGs should be obtained.

Answer to Question 2

1

Rationale 1:The action potential of the sinoatrial (SA) node leaves and travels to the atria of the atrioventricular (AV) node, a small area of specialized fibers that lies in the wall separating the two atria. If the SA node malfunctions, the AV node has the ability to generate action potentials.
Rationale 2:The sinoatrial (SA) node or pacemaker of the heart will generate a new action potential approximately 75 times every minute under resting conditions.
Rationale 3:The client is asking about the AV node and not the mechanical disruption of force that doesn't exist.
Rationale 4:The force of contraction is the cardiac output.

Global Rationale: The action potential of the sinoatrial (SA) node leaves and travels to the atria of the atrioventricular (AV) node, a small area of specialized fibers that lies in the wall separating the two atria. If the SA node malfunctions, the AV node has the ability to generate action potentials.
