A patient arrives in the emergency department for chest pain, lightheadedness, and shortness of breath (SOB). The cardiac monitor shows sinus rhythm with the presence of multifocal PVCs. Which order would the nurse question?
1. Oxygen at 4 L/min via nasal cannula
2. Morphine sulfate 2 mg IV
3. Atropine 0.5 mg IV
4. Amiodarone 300 mg IV
3
Rationale 1: Oxygen is indicated for shortness of breath.
Rationale 2: Morphine is administered for chest pain.
Rationale 3: Atropine would be questioned because atropine is the drug of choice for unstable bradycardia, not ventricular irritability.
Rationale 4: Amiodarone is the drug of choice to decrease ventricular irritability and multifocal PVCs.
