d. hepatomegaly. - correct-answer-Pulmonary congestion with dyspnea
A middle-aged patient has a follow up visit for a recorded blood pressure of
162/96 mm Hg taken 3 weeks ago. The patient has nosignificant past medical
history and takes no medications, but smokes 1 1/2 packs of cigarettes per day,

º protecting the heart from further ischemia.
º decreasing myocardial oxygen demands.
º reducing heart rate and blood pressure.
º activating the parasympathetic system. - correct-answer-Decreasing myocardial
oxygen demands

º Sinus bradycardia
º Third-degree heart block
º Junctional tachycardia - correct-answer-Ventricular escape rhythm
ºA ventricular escape rhythm originates in the Purkinje fibers, has a rate of 15 to
40 beats/minute, and is characterized by a wide QRS complex.
The majority of tachydysrhythmias are believed to occur because of
º triggered activity.
º enhanced automaticity.
º defective gap junctions.
º reentry mechanisms. - correct-answer-Reentry mechanisms
ºReentry is a complex process in which a cardiac impulse continues to depolarize
in a part of the heart after the main impulse has finished its path.
The prevalence of high blood pressure is higher in
