A patient arrives in the triage area with complaints of episodic heart palpitations, dizziness, and a fear of impending doom. They report a previous diagnosis of both mitral valve prolapse and generalized anxiety disorder. During an episode in the ED, after an unremarkable workup, which intervention should the nurse prioritize to both assess and manage the patient's current symptoms?
Administer a 12-lead ECG to look for potential arrhythmic events.
Provide the patient with a dose of aspirin while waiting for further test results.
Schedule an echocardiogram to assess the function of the patient's mitral valve.
Perform the Valsalva maneuver to observe changes in the patient’s symptoms.
