QUIZ 2 GRC/PD 1st Rotation SPMC

A patient presents with an irregularly irregular heart rhythm and no distinct P waves on ECG. What is the arrhythmia

• Atrial fibrillation
• Supraventricular tachycardia
• Ventricular Fibrillation

• Ventricular tachycardia

What is the most likely arrhythmia and immediate treatment if a young adult suddenly develops a rapid heartbeat with regular narrow QRS complexes and no visible P waves?

• Ventricular tachycardia; immediate treatment: defibrillation.
• Atrial fibrillation; immediate treatment: beta-blockers.
• Torsades de Pointes; immediate treatment: MgSO4.

• Supraventricular tachycardia (SVT); immediate treatment: adenosine.

An ECG shows two consecutive wide, bizarre QRS complexes not preceded by P waves, followed by a pause

What is the immediate drug of choice for Torsades de Pointes?

A patient is unresponsive with ECG showing disorganized, chaotic electrical activity with no identifiable waves

Frequent and consecutive premature ventricular contractions (PVCs), especially in the setting of underlying heart disease or electrolyte imbalance, may lead to which life-threatening arrhythmia?

A patient suddenly collapses. The ECG monitor shows a chaotic, disorganized rhythm with no identifiable P, QRS, or T waves. What is the immediate life-saving intervention?

• Complete this ECG statement
  "Longer, longer, longer, drop — then you have a __________."

Which simple bedside assessment tool is commonly used to predict difficult intubation by evaluating mouth opening, tongue size, and visibility of the oropharynx?

What is the most reliable bedside method for confirming correct endotracheal tube placement?

• Capnography
• Listening for breath sounds
• Chest Xray

• Checking for chest rise
