junctional Dysrhythmias
| Question | Answer |
|---|---|
| A 59-year-old patient arrives at the emergency department and with chest discomfort for the past 24 hours. An ECG reading shows a heart rate of 58, a regular rhythm with a normal QRS complex, and an inverted P wave on the fourth beat. | -- |
| Which conclusion can be made about the intrinsic pacemaker in this patient’s heart? | The impulse is coming from the AV node, because the SA node is either not functioning or the impulse is blocked. |
| A 65-year-old patient with a 20-year history of CAD receives an ECG that shows a variable PR interval with no relationship between the P wave and the QRS complex. The nurse notes which type of heart block? | Third-degree heart block |
| The nurse examines the patient’s ECG and notices that there is a junctional rhythm. Which area of the heart is controlling the heart rate? | AV node |
| A patient with a history of HF reports chest pain. An ECG shows a prolonged PR interval that remains constant on conducted beats. The QRS complex is 0.14 seconds. Which action does the nurse take for management of this patient? | Prepare the patient for insertion of a temporary pacemaker |
| A patient has the ECG strip shown here as most current in the chart and has been experiencing very low blood pressures. The nurse should expect to collaborate with the care team on which procedure for this patient? | Temporary pacemaker placement |
| A patient has blood pressure 88/56 and heart rate 33 bpm with the ECG strip shown here. After the appropriate care team members are notified, which intervention should be performed first? | Administer dopamine |
