A client is admitted with uncontrolled atrial fibrillation with a rate between 120's-130's. IV heparin therapy is prescribed. In addition, the nurse prepares the client for a transesophageal echocardiogram (TEE). What does the nurse understand about this diagnostic study?

A. Complete the remainder of the assessment: While ongoing assessment is important, the rhythm strip shows atrial flutter, a potentially unstable arrhythmia, and the client is experiencing symptoms (nausea after breakfast) which could suggest compromised cardiac output. Completing the remainder assessment delays the necessary intervention.

B. Obtain an order for adenosine IV: Adenosine is typically used for stable supraventricular tachycardia (SVT), not for atrial flutter, as it may not terminate the rhythm. It may slow conduction enough to better visualize flutter waves, but initiating it without a provider's order or further evaluation is inappropriate.

C. Notify the physician of the symptoms: The client’s rhythm strip shows atrial flutter with a rapid ventricular response and the patient is experiencing nausea, which could indicate decreased perfusion or early decompensation. Immediately notifying the provider is the safest and most appropriate action for further evaluation and treatment planning.

D. Administer the prescribed ACE inhibitor: ACE inhibitors are used for blood pressure control or heart failure management, not for acute rhythm disturbances. Administering it would not address the current rhythm or symptoms and could worsen hypotension if cardiac output is compromised.

A. "All patients with this disorder have a genetic defect which causes it.": Restrictive cardiomyopathy is not primarily a genetic disorder. While there may be rare familial forms, most cases are acquired, often secondary to systemic diseases, making this statement inaccurate and misleading.

B. "There are many theories about its development but amyloidosis in your history is a probable cause.": This is the most accurate response. Restrictive cardiomyopathy is commonly associated with infiltrative diseases such as amyloidosis, hemochromatosis, and sarcoidosis, which impair ventricular filling due to stiff, non-compliant myocardium.

C. "You probably had a silent heart attack which caused this disorder.": Silent myocardial infarctions can contribute to ischemic cardiomyopathy, typically leading to dilated, not restrictive, changes in the myocardium. They are not a primary cause of restrictive cardiomyopathy.

D. "Your long-standing hypertension caused this disorder.": Chronic hypertension more commonly leads to left ventricular hypertrophy and may contribute to diastolic heart failure, but it is not a typical cause of restrictive cardiomyopathy.
