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

Atenolol (Tenormin)
Propranolol (Inderal)
Bisoprolol (Zebeta)
Acebutolol (Sectral)
Comolol (Brevibloc) Correct Answer: Beta Blockers - used for blood pressure and cardiac problems
Epinephrine
Norepinephrine
Vasopressin
Dopamine
Phenylephrine
Dobutamine Correct Answer: 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 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 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

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
