Fisdap Cardiology Exam
Where are Beta 1 receptors found? Correct Answer: Heart and Kidneys
Stimulation of Beta 1 receptors results in an increase of what? Correct Answer: 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 Answer: 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 Answer: P wave
Carvedilol (Coreg)
Metropolol (Lopressor)
Atenolol (Tenormin)
Propranolol (Inderal)
Bisoprolol (Zebeta)
Acebutolol (Sectral)
Comolol (Brevibloc) Correct Answer: Beta Blockers - used for blood pressure and cardiac problems
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 Answer: Relative Refractory Period
(Partial flush of the toilet)
Starlings Law Correct Answer: 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 Answer: 20-40
Intrinsic Rate for AV Junction Correct Answer: 40-60
Treatment for Beta Blocker Overdose Correct Answer: Glucagon: 1-5mg IV/IO (1st Line Drug)
, Calcium Chloride: 500mg - 1g IV/IO

Indications Correct Answer: Nitrate Vasodilator and Antianginal
Relaxes vascular smooth muscle = vasodilation and venous pooling which Reduces Preload/Afterload
and Dilates Coronary Arteries which increases myocardial perfusion.

Pulse Ox, O2, Monitor vitals for embolism.
Do not massage affected limb.
The pressure gradient that drives coronary blood pressure.
The difference between aortic diastolic pressure and left ventricular end diastolic pressure that perfuses
the coronary arteries. Correct Answer: Coronary Perfusion
Tachycardia, Difficulty Breathing, Diminished Lung Sound, Pulse Quality Changes, and unequal chest rise
are early signs and symptoms of? Correct Answer: Tension Pneumothorax
Air is entering the pleural space but cannot escape. Positive pressure ventilation can make it worse.
Criteria for Unstable Dysrhythmia Correct Answer: Ischemic Chest Pain
ALOC
Hypotension/Hypovolemia
Signs of Shock
Acute Heart Failure
Restriction of of cardiac contraction, falling cardiac output, and shock as a result of pericardial fluid
accumulation are characteristics of? Correct Answer: Cardiac Tamponade
