Basic ECG interpretation
| Question | Answer |
|---|---|
| Which statement describes the role of the Purkinje fibers in the pathway of the normal cardiac cycle? | Conduction of impulses through the ventricles leading to ventricular muscle contraction |
| Which action results in the atria after firing of the sinoatrial (SA) node? | Contraction of the atria to move blood to the ventricles |
| Which physiologic process is responsible for repolarization of heart cells? | Movement of sodium out of the cell |
| The nurse is reviewing a patient’s ECG reading and notices artifact on the monitor. Which action should the nurse perform to identify the cause of the artifact? | Determine the condition of the conductive gel on the electrodes |
| A nursing student is discussing a rhythm strip with the faculty member. Which rationale explains a shortened QT interval? | A Faster heart rate |
| Using the R-R interval formula, the heart rate in the strip shown measures | 80 Beats per minute |
| The nurse obtains an ECG for a 53-year-old patient with chest pain. The nurse palpates a heart rate of 106. Which alteration in waveform should the nurse expect to see on the ECG tracing? | Short QT intervals |
| The nurse is caring for a patient with chest tightness and shortness of breath. The ECG tracing reports sinus tachycardia. Which additional finding should be expected? | Heart rate is 114 beats per minute |
| The nurse is providing patient education regarding bradycardia and its management. Further teaching is required if the patient makes which statement? | “My heart rate may be slower if I discontinue my calcium channel blockers.” |
| Patient reports no clinical signs or symptoms; HR is 80 bpm | Sinus rhythm |
| Patient reports exhaustion and episodes of fainting; HR is 50 bpm | Sinus Bradycardia |
| Patient reports being in extreme emotional stress; HR is 102 bpm | Sinus tachycardia |
| A patient calls the health care provider’s office reporting dizziness and fatigue. The patient started taking a beta blocker one week ago. The patient’s radial pulse is 52 bpm. Which instruction should the nurse give the patient? | “Consult your health care provider about stopping the beta blocker.” |
| A patient reports dizziness and dyspnea. On assessment, the patient’s heart rate is 130 bpm. An ECG indicates normal P-wave, PR interval, and QRS complex. | -- |
| The patient reports that the symptoms began shortly after an injury causing acute back pain. What is the priority intervention for this patient? | Administer pain medications as prescribed. |
| A patient presents with sinus tachycardia with a heart rate of 122. The patient also has pneumonia. Which assessment question should the nurse ask the patient first to identify the cause of the patient’s symptoms? | "Have you taken any over-the-counter medications since you became sick?" |
| A patient presents during a normal well-visit with a heart rate of 58 beats per minute. The patient is an avid runner and is currently training for a triathlon. All other vital signs are normal. | -- |
| Which statement indicates to the nurse the patient teaching is understood? | “I do not need to take any medications. My heart rate is expected because of my triathlon training.” |
