NRNP 6566 Week 3 Knowledge Check Quiz Q&A • Question 1 Mrs. Franklin is a 68-year-old woman with long-standing, persistent AF being managed with rhythm control on dofetilide. She also has type 2 diabetes mellitus (T2DM), hypertension, and a myocardial infarction 3 years ago. What is her CHADS2 and CHA2DS2-VASc score? How would you interpret those scores in deciding on treatment for Mrs. Franklin? Correct Answer: CHADS2 score=2 (HTN, T2DM) A score of greater than 2 is considered high risk for stroke. CHA2DS2-VASc score=5 (age 65, female, HTN, T2DM, coronary artery disease [CAD]) A score of greater than 2 is considered high risk for stroke. Many patients are hesitant to begin anticoagulation due to the expense and inconvenience. However, after understanding that a 4% annual risk for stroke (if the CHA2DS2-VASc Score is 4) equates to 40% risk over 10 years, patients are more willing to comply. • Question 2 A 58-year-old male complains of a galloping heart rate and shortness of breath.
