You hear an alarm on the central monitor and observe a patient with an abnormal rhythm. What is your first action?

• A. Check monitor settings
• B. Call the physician
• C. Document the event
• D. Assess your patient

Answer: (D)

Assessing the patient first is essential when you hear a monitor alarm with an abnormal rhythm. The monitor can alarm for real changes or for artifacts, lead issues, or transient nonpulsatile rhythms. By quickly evaluating the patient, you determine who needs immediate action and who may simply need a quick adjustment.

Start with a rapid bedside check: is the patient awake and responsive? Are they breathing adequately? Is there a pulse, and is it weak or strong? Look for signs of distress, chest pain, shortness of breath, diaphoresis, or alterations in color or mentation. At the same time, quickly inspect the leads and site connections to rule out loose or displaced leads that could create a false rhythm reading. If the patient is unstable—for example, hypotensive, confused, with chest pain, or showing poor perfusion—you follow your emergency protocol right away and call for help while implementing necessary measures (positioning, oxygen, CPR/defibrillation if indicated). If the patient appears stable, you can collaborate to verify the rhythm on the monitor and address lead issues or notify the physician as the next step. The priority is to confirm the patient's actual status before focusing on monitor adjustments or escalation.
