New Palpitations and Dizziness on a Nurse Triage Line
At 21:15, a 68-year-old woman calls a nurse triage line reporting a 2-hour history of 'fluttering' in her chest and dizziness when she stands. She has a history of hypertension, type 2 diabetes, and paroxysmal atrial fibrillation; she takes metoprolol, apixaban, and metformin. She denies chest pain, shortness of breath at rest, fainting, or vomiting. Her home blood pressure is 158/92, pulse 112 and irregular, temperature 98.4°F, and blood glucose 142 mg/dL. She lives alone, has a neighbor who can drive her, and says she does not want to 'bother' the emergency department. She has no fever, no calf pain, and no recent surgery. She is alert and oriented. The nurse must determine disposition and what to ask next.
1. What triage acuity and disposition are appropriate? Explain the reasoning.
Read the worked answer
This is not a home-care call. The combination of new or worsening palpitations, an irregular pulse of 112, dizziness on standing, age 68, and a cardiac history raises concern for atrial fibrillation with rapid ventricular response or another arrhythmia. The blood pressure is elevated rather than low, but dizziness suggests some hemodynamic effect. She is anticoagulated, which lowers stroke risk but does not eliminate it.
The appropriate disposition is same-day emergency department evaluation. Urgent care is a weaker choice because it may not have continuous cardiac monitoring or rapid access to ECG and electrolytes. A primary care visit the next morning is too delayed. She should not drive herself. A neighbor driving is acceptable only if she remains stable and the nurse confirms someone stays with her; if she worsens, EMS should be called. The reasoning is that arrhythmia risk can change quickly, and a normal temperature and glucose do not rule out a cardiac cause.
2. What additional questions and red flags would you screen for?
Read the worked answer
Ask whether this feels like her usual atrial fibrillation, when it started, and whether she has had similar episodes. Ask about medication adherence, especially missed metoprolol or apixaban. Screen for chest pain, shortness of breath, fainting or near-fainting, focal weakness, speech change, severe headache, bleeding, recent fall, fever, calf swelling, and thyroid symptoms. Ask about caffeine, alcohol, and stimulant use.
Red flags that change the plan to 911 include chest pain, dyspnea at rest, syncope, hypotension, altered mental status, stroke symptoms, severe bleeding, or a fall with injury. The reasoning is to separate a stable but urgent arrhythmia from a hemodynamically unstable or embolic event. A home ECG device reading, if available, is useful but does not replace evaluation.
3. What advice should the nurse give, including safety-netting?
Read the worked answer
Advise her not to drive herself. Arrange the neighbor to take her to the emergency department now, or call EMS if she feels worse while waiting. Tell her to continue her usual medications unless a clinician advises otherwise, and not to double-dose metoprolol. Bring a medication list and the home blood pressure and pulse readings. Confirm that someone will stay with her or that she has a way to call for help.
Safety-net clearly: if she develops chest pain, shortness of breath, fainting, one-sided weakness, trouble speaking, or severe bleeding, she should call 911 immediately. Do not wait until morning. If she refuses the emergency department, explain the risks in plain language, offer EMS, and document the refusal and the advice given. The reasoning is that a stable phone conversation can change, and the nurse must ensure the patient has a safe plan rather than only a recommendation.
