Chapter 25. Nursing Care of Patientswith Cardiac Dysrhythmias
After reviewing an electrocardiogram, the nurse determines that an electrical impulse
originated in a patient's sinoatrial node. What did the nurse see on this tracing?
1. An upright T wave
2. An inverted T wave
3. A positive P wave before a QRS complex
4. A negative P wave before a QRS complex
Page: 437 - answerANS: 3
Feedback
1 This wave does not indicate that the electrical impulse originated in the sinoatrial (SA)
node.
2 This wave does not indicate that the electrical impulse originated in the SA node.
3 A positive P wave before a QRS complex indicates that an electrical impulse
originated in the SA node.
4 This wave does not indicate that the electrical impulse originated in the SA node.
The nurse is reinforcing teaching for a patient who has a pacemaker. Which measure
should the nurse include when explaining how the pulse should be monitored?
1. Take radial pulse for 1 minute.
2. Take apical pulse for 1 minute.
3. Take jugular pulse for 30 seconds.
4. Take brachial pulse for 30 seconds.
Page: 451 - answerANS: 1
Feedback
1 Patients are taught to take a radial pulse, as it is easier to learn than an apical pulse,
for 1 minute and to report if it is five beats over or under the set pacemaker rate
2 It is difficult for a patient to learn how to take his or her own apical pulse.
3 This pulse point is difficult for the patient to learn.
4 This pulse point is difficult for the patient to learn.
The nurse is sitting at the desk watching the telemetry monitors and notes a patient's
rhythm suddenly shows asystole. Which action should the nurse take first?
1. Start cardiopulmonary resuscitation (CPR).
2. Document the rhythm as normal.
, 3. Prepare to administer adenosine (Adenocard).
4. Prepare the patient for cardioversion.
Page: 450 - answerANS: 1
Feedback
1 When the rhythm reads asystole, CPR is started immediately.
2 When the rhythm reads asystole, CPR is started immediately.
3 When the rhythm reads asystole, CPR is started immediately.
4 When the rhythm reads asystole, CPR is started immediately.
The nurse is caring for a patient receiving warfarin (Coumadin). Which finding would be
of most concern to the nurse?
1. The patient reports blood in the urine.
2. The patient reports nausea.
3. The patient's apical heart rate is 72 beats/min.
4. The patient has a dry cough.
Page: 447 - answerANS: 1
Feedback
1 Hematuria indicates the patient may be receiving too much Coumadin.
2 Nausea is not a priority.
3 The heart rate is normal.
4 Dry cough is not the most concerning effect.
A patient is diagnosed with ventricular fibrillation. For which emergency intervention
should the nurse anticipate preparing?
1. Defibrillation
2. Endotracheal intubation
3. Synchronized cardioversion
4. Cardiopulmonary resuscitation
Page: 450 - answerANS: 1
Feedback
1 Defibrillation is the best treatment for ventricular fibrillation to terminate it and increase
survival.
2 Endotracheal intubation will ensure oxygenation; however, it will not affect the lethal
heart rhythm.
3 Synchronized cardioversion is not indicated for this heart rhythm.
4 CPR may need to be started if defibrillation is not effective.
The nurse is reviewing the cardiac strip for a patient and notes the following: No
identifiable P waves, QRS complex measures 0.06 second and irregular, and heart rate
120 beats/min. The nurse should interpret this as which arrhythmia?
1. Normal sinus rhythm
