Question : When a murmur is first heard, it is important to determine if it is due to a pathological condition or benign. For an experienced practitioner, it is always easy to determine the cause of a murmur merely by listening to the sound. Is this statement true or false? Student Answer: True False (This statement is false: for an experienced practitioner, it is always easy to determine the cause of a murmur merely by listening to the sound) -514937575 MultipleChoice 85 True 0 -514937575 MultipleChoice 85 Question 39 . Question : Maintenance of an Isometric ST-segment during exercise is the response of? Student Answer: A normal heart (Maintenance of an Isometric ST-segment during exercise is the response of a normal heart. ) Hypo profusion An abnormal heart CAD Question 40 . Question : The goal of self-management is to specifically do what? Student Answer: Engage patients in their own care (The goal of self- management is to engage patients in their own care.) Engage insurance providers in patient care Engage providers in patient care Engage government in greater involvement in patient care -514937573 MultipleChoice 52 True 0 -514937573 MultipleChoice 52 Question 41 . Question : Your 56-year old patient presents with bradycardia with a rate of 55 and first degree AV block. The patient is hemodynamically stable and is not experiencing any syncope or chest pain. History includes previous myocardial infarction. Home medications include beta blockers, daily aspirin. Lab work is non-significant for electrolyte imbalance. You decided to treat this patient for the arrhythmia to prevent future destabilization. From the choices below, which might be the appropriate first measure to consider? Student Answer: Add digitalis to control the heart rate Consult cardiologist immediately for guidance Discontinue Beta Blocker and replace with another therapy if necessary (The appropriate first measure to consider is to discontinue the beta blocker and replace with another therapy if necessary.)
