1. The nurse is caring for a patient who is receiving an ECG. The nurse notes that leads I, II, and III differ from one another on the cardiac rhythm strip. Why is this?
2. A) The view of the electrical current changes in relation to the lead placement.
3. B) Conduction of the heart differs with lead placement.
4. C) Electrocardiogram (ECG) equipment has malfunctioned.
5. D) The circadian rhythm has changed.

 

Ans:  A

Chapter:  27

Client Needs:  D-4

Cognitive Level:  Analysis

Difficulty:  Moderate

Integrated Process:  Nursing Process

Objective:  2

Feedback:  Each lead offers a different reference point to view the electrical activity of the heart. The lead displays the configuration of electrical activity of the heart.

 

 

 

 

2. The nurse is analyzing a rhythm strip. What does the nurse look at to identify the resting state of the heart?
3. A) P wave
4. B) T wave
5. C) U wave
6. D) QRS complex

 

Ans:  B

Chapter:  27

Client Needs:  D-4

Cognitive Level:  Analysis

Difficulty:  Moderate

Integrated Process:  Nursing Process

Objective:  1

Feedback:  The T wave represents ventricular muscle depolarization, also referred to as the resting state.

 

 

 

 

3. The staff educator is teaching a class on conduction problems in the heart. The educator explains that in an adult patient who has damage to the electrical conduction of the ventricles of the heart, the nurse would expect to see changes in what?
4. A) P wave
5. B) T wave
6. C) QRS complex
7. D) U wave

 

Ans:  C

Chapter:  27

Client Needs:  D-4

Cognitive Level:  Analysis

Difficulty:  Moderate

Integrated Process:  Teaching/Learning

Objective:  3

Feedback:  The QRS complex represents the depolarization of the ventricles and, as such, the electrical activity of that ventricle.

 

 

 

 

4. An adult patient with third-degree AV block is admitted to your unit and placed on continuous cardiac monitoring. What rhythm characteristics will the EKG show?
5. A) PP interval and RR interval are irregular
6. B) PP interval equal to RR interval
7. C) Fewer QRS complexes than P waves
8. D) PR interval constant

 

Ans:  C

Chapter:  27

Client Needs:  D-4

Cognitive Level:  Analysis

Difficulty:  Difficult

Integrated Process:  Nursing Process

Objective:  4

Feedback:  In third-degree AV block, no atrial impulse is conducted through the AV node into the ventricles. As a result, there are impulses stimulating the atria and impulses stimulating the ventricles. Therefore, there are more P waves than QRS complexes due to the difference in the natural pacemaker (nodes) rates of the heart.

 

 

 

 

5. You are writing a plan of care for a patient with a cardiac dysrhythmia. What would be the most appropriate goal for the patient?
6. A) Maintain nutritional intake
7. B) Maintain fluid intake
8. C) Maintain cardiac output
9. D) Maintain social contacts

 

Ans:  C

Chapter:  27

Client Needs:  D-4

Cognitive Level:  Application

Difficulty:  Moderate

Integrated Process:  Communication and Documentation

Objective:  5

Feedback:  For patient safety, the most appropriate goal is to maintain cardiac output to prevent worsening complications as a result of decreased cardiac output.
