PALS version A questions and answers already passed You are caring for a child who was resuscitated after a drowning event. The child is intubated and ventilated with 100% oxygen with equal breath sounds and exhaled CO2 detected. The heart rate is slow and the monitor shows sinus bradycardia. The skin is cool, mottled, and moist; distal pulses are not palpable and the central pulses are weak. Intravenous access has been established. The core temperature is 37.3oC. Based on the PALS bradycardia ...

Dysrhythmia - cORRECT sOLUTION Any disorder of the heart beat or heart rhythm. Cardiac output is impaired. Cellular oxygenation is then also impaired Electrical problem will definitely effect the mechanical but a mechanical problem may not effect the electrical. Explaining dysrhythmias - cORRECT sOLUTION -Classified to their site of origin -SA node atrial tissue, AV node, junctional tissue (tissue around AV node), and ventricular tissue -Caused by a disturbance in impulse formation ...

National Telemetry Association Cardiac Arrhythmia Exam Questions and Answers Rated A+ What is the definition of a cardiac arrhythmia? A cardiac arrhythmia is any irregularity in the normal rhythm of the heart, which can manifest as a faster, slower, or irregular heartbeat. How is atrial fibrillation different from ventricular fibrillation? Atrial fibrillation involves irregular electrical activity in the atria, often leading to a rapid and erratic heart rate. Ventricular fibril...
