Fisdap Cardiology Exam 100% Solved
Where are Beta 1 receptors found? -CORRECT ANS-Heart and Kidneys
Stimulation of Beta 1 receptors result in an increase of what? -CORRECT ANS-Heart: Inotropy,
Chronotropy, Dromotropy
Kidneys: Renin-Angiotensin-Aldosterone System = Vasoconstriction = Increase blood pressure
Which node is located at the junction of the superior vena cava and the right atrium, is typically supplied
by the Right Coronary artery, and fires at a rate of 60-100 bpm. -CORRECT ANS-SA Node
Atrial depolarization characterized by smooth, round, upright deflection less than 0.11 secs long and less
than 2.5mm tall is referred to as what on the ECG? -CORRECT ANS-P wave
Carvedilol (Coreg)
Metropolol (Lopressor)
Atenolol (Tenormin)
Propranolol (Inderal)
Bisoprolol (Zebeta)
Acebutolol (Sectral)
Comolol (Brevibloc) -CORRECT ANS-Beta Blockers - used for blood pressure and cardiac problems
Epinephrine
Norepinephrine
Vasopressin
Dopamine
Phenylephrine
Dobutamine -CORRECT ANS-Vasopressors
, The middle of phase 3 to beginning of phase 4 in the cardiac cycle where cardiac cells are partially
refractory and partially repolarized and certain cells can be depolarized in response to electrical
stimulus. -CORRECT ANS-Relative Refractory Period
(Partial flush of the toilet)
Starlings Law -CORRECT ANS-When end diastolic volume increases, stroke volume increases as well.
(When more blood is in the ventricles, the cardiac muscle stretches like rubber band and creates more
forceful contraction)
Intrinsic Rate for Ventricles (Purkinje Fibers) -CORRECT ANS-20-40
Intrinsic Rate for AV Junction -CORRECT ANS-40-60
Treatment for Beta Blocker Overdose -CORRECT ANS-Glucagon: 1-5mg IV/IO (1st Line Drug)
Calcium Chloride: 500mg - 1g IV/IO
Why do we give Nitro for chest pain?
Class
MOA
Indications -CORRECT ANS-Nitrate Vasodilator and Antianginal
Relaxes vascular smooth muscle = vasodilation and venous pooling which Reduces Preload/Afterload
and Dilates Coronary Arteries which increases myocardial perfusion.
Cardiac Chest Pain
Acute Pulmonary Edema
