Understanding Pacemaker Rhythms Cardiac Review – Slides

 




CARDIOVASCULAR NCLEX QUIZ QUESTIONS

 

Question 1:  You begin your shift and assess an electrocardiogram rhythm strip. The P waves and QRS complexes are regular. The PR interval is 0.12 seconds, and the QRS complexes are 0.10 seconds. You notice a pacer spike prior to each p wave.The overall heart rate is 80 beats per minute. The nurse assesses the cardiac rhythm as:

A. Single Chamber Atrial Pacemaker

B. Normal Sinus Rhythm

C. Single Chamber Ventricular Pacemaker

D. Failure to Capture

 

Question 2: You begin your shift and assess an electrocardiogram rhythm strip. The P waves and QRS complexes are regular. The PR interval is not measurable, and the QRS complexes are 0.16 seconds. You notice a pacer spike prior to each Q wave.The overall heart rate is 80 beats per minute. The nurse assesses the cardiac rhythm as:

A. Single Chamber Atrial Pacemaker

B. Normal Sinus Rhythm

C. Single Chamber Ventricular Pacemaker

D. Failure to Capture

 

Question 3: True or False: Dual chamber pacemakers will exhibit pacer spikes only before the Q wave.

 

Question 4: Upon assess your patient’s ECG, you notice there is a failure to recognize the intrinsic rhythm resulting in a pacer spike falling close to another beat. This is called:

A. Failure to Sense – Undersensing

B. Failure to Sense – Oversensing

C. Failure to Capture

D. Dual Chamber Pacemaker

 

Question 5: Upon assess your patient’s ECG, you notice there is a P wave without a QRS complex after. You believe the pacemaker identified the P wave was an extra electrical activity causing the pacemaker not to fire. This is called:

A. Failure to Sense – Undersensing

B. Failure to Sense – Oversensing

C. Failure to Capture

D. Dual Chamber Pacemaker

 

Question 6: Upon assess your patient’s ECG, you notice there are pacer spikes without constant QRS complexes. You believe the pacemaker provided a stimulus but depolarization did not occur. This is called:

A. Failure to Sense – Undersensing

B. Failure to Sense – Oversensing

C. Failure to Capture

D. Dual Chamber Pacemaker
