Ch. 36 Dysrhythmias Questions and Answers scored A To determine whether there is a delay in impulse conduction through the atria, the nurse will measure the duration of the patient's - ANS- P wave. The nurse needs to quickly estimate the heart rate for a patient with a regular heart rhythm. Which method will be best to use? - ANS- Use the 3-second markers to count the number of QRS complexes in 6 seconds and multiply by 10. A patient has a junctional escape rhythm on the monitor. The nurse will expect the patient to have a heart rate of _____ beats/minute. - ANS- 40 to 60 The nurse obtains a rhythm strip on a patient who has had a myocardial infarction and makes the following analysis: no visible P waves, P-R interval not measurable, ventricular rate 162, R-R interval regular, and QRS complex wide and distorted, QRS duration 0.18 second. The nurse interprets the patient's cardiac rhythm as - ANS- ventricular tachycardia. The nurse notes that a patient's cardiac monitor shows that every other beat is earlier than expected, has no visible P wave, and has a QRS complex that is wide and bizarre in shape. How will the nurse document the rhythm? - ANS- Ventricular bigeminy A patient has a normal cardiac rhythm and a heart rate of 72 beats/minute. The nurse determines that the P-R interval is 0.24 seconds. The most appropriate intervention by the nurse would be to - ANS- document the finding and continue to monitor the patient. A patient who was admitted with a myocardial infarction experiences a 45-second episode of ventricular tachycardia, then converts to sinus rhythm with a heart rate of 98 beats/minute. Which of the following actions should the nurse take next? - ANS- Prepare to give IV amiodarone (Cordarone) per agency dysrhythmia protocol. After the nurse gives IV atropine to a patient with symptomatic type 1, second-degree atrioventricular (AV) block, which finding indicates that the medication has been effective? - ANS- Increase in the patient's heart rate A patient with dilated cardiomyopathy has new onset atrial fibrillation that has been unresponsive to drug therapy for several days. The priority teaching needed for this patient would include information about - ANS- anticoagulant therapy. Which information will the nurse include when teaching a patient who is scheduled for a radiofrequency catheter ablation for treatment of atrial flutter? - ANS- The procedure will use electrical energy to destroy areas of the conduction system. After providing a patient with discharge instructions on the management of a new permanent pacemaker, the nurse knows that teaching has been effective when the patient states - ANS- "I won't lift the arm on the pacemaker side up very high until I see the doctor." Which intervention by a new nurse who is caring for a patient who has just had an implantable cardioverter-defibrillator (ICD) inserted indicates a need for more education about care of patients with ICDs? - ANS- The nurse assists the patient to do active range of motion exercises for all extremities. Which action should the nurse perform when preparing a patient with supraventricular tachycardia for cardioversion who is alert and has a blood pressure of 110/66 mm Hg? - ANS- Give a sedative before cardioversion is implemented. A 20-year-old has a mandatory electrocardiogram (ECG) before participating on a college soccer team and is found to have sinus bradycardia, rate 52. Blood pressure (BP) is 114/54, and the student denies any health problems. What action by the nurse is most appropriate? - ANS- Allow the student to participate on the soccer team When analyzing the rhythm of a patient's electrocardiogram (ECG), the nurse will need to investigate further upon finding a(n) - ANS- QRS interval of 0.14 second
