BAMC Tele Questions and Answers Already Passed What’s the difference between an artifact and a real event in telemetry monitoring? An artifact in telemetry is caused by external factors like patient movement or poor electrode contact, leading to false alarms, while a real event is an actual physiological change such as arrhythmia or ischemia. How can you distinguish between a PVC (premature ventricular contraction) and a normal beat on telemetry? A PVC typically occurs earlier than expected, has a wider and more distorted QRS complex, and may be followed by a compensatory pause, whereas a normal beat follows the regular rhythm and has a normal shape and timing. What should be done if a telemetry monitor shows a run of ventricular tachycardia? Ventricular tachycardia should be treated immediately as it can lead to life-threatening conditions. The provider should assess the patient’s stability, ensure the airway is open, and prepare for possible intervention like defibrillation. What is the role of telemetry in monitoring patients with atrial fibrillation? 2 Telemetry helps track the irregular rhythms and heart rate fluctuations in atrial fibrillation, providing real-time data to adjust medication or interventions, such as anticoagulants or rate- control drugs, to prevent complications like stroke. What factors can influence the accuracy of telemetry readings? Factors like electrode placement, skin condition, body movement, and electromagnetic interference can all impact the accuracy of telemetry readings, potentially leading to false alarms or missed detections of critical events. Why is a flatline (asystole) on telemetry considered a medical emergency? A flatline indicates no electrical activity in the heart, signaling asystole, which is a life- threatening emergency requiring immediate CPR and, potentially, advanced life support, to attempt resuscitation. How can telemetry assist in identifying early signs of myocardial infarction? Telemetry can detect characteristic changes in the heart's electrical activity, such as ST- segment elevation or T-wave inversion, which are key indicators of myocardial ischemia or infarction, prompting immediate action for intervention. What actions should be taken if a telemetry monitor shows sinus tachycardia? 3 Sinus tachycardia should be assessed for the underlying cause, such as fever, pain, hypovolemia, or stress. Treatment may involve addressing the cause, such as hydration, pain management, or adjusting medications. What can lead to artifact on a telemetry strip? Artifacts can be caused by poor electrode contact, patient movement, electrical interference from devices, or even muscle contractions, all of which can distort the telemetry readings and lead to false alarms. What does a T-wave inversion signify on a telemetry strip? T-wave inversion can indicate myocardial ischemia, electrolyte imbalances, or other heart- related issues. It may require further evaluation to determine the underlying cause and whether it necessitates intervention.
