AF Patient Assessment & Clinical Evaluation 2

Question 1

A patient with known AF presents with a resting heart rate of 128 bpm. Which clinical finding would most suggest rate control is inadequate?

Accepted Answer

Exertional dyspnea and fatigue at minimal activity

Answer

Symptoms of dyspnea and fatigue at minimal exertion indicate that the ventricular rate is inadequate controlled and is impairing cardiac output.

Question 2

When performing a structured clinical assessment for a new AF patient, which historical element is MOST critical for guiding anticoagulation decisions?

Accepted Answer

Prior stroke or transient ischemic attack

Answer

Prior stroke or TIA is a strong independent risk factor for thromboembolic events in AF and adds points to the CHA₂DS₂-VASc score.

Question 3

A 70-year-old man with AF, hypertension, and diabetes presents for evaluation. His CHA₂DS₂-VASc score is 4. What is the recommended next step?

Accepted Answer

Initiate oral anticoagulation

Answer

A CHA₂DS₂-VASc score ≥2 in men warrants oral anticoagulation to reduce stroke risk.

Question 4

During auscultation of a patient with AF, the examiner notes an irregularly irregular rhythm. Which additional physical finding best supports hemodynamic compromise?

Accepted Answer

Hypotension and diaphoresis

Answer

Hypotension and diaphoresis indicate hemodynamic instability, which may require urgent rate control or cardioversion.

Question 5

Which medication class used in the assessment workup of AF can cause the condition as a side effect?

Accepted Answer

Thyroid hormone supplementation

Answer

Excessive exogenous thyroid hormone can precipitate AF by increasing adrenergic tone and atrial automaticity.
