FISDAP READINESS, FISDAPReadiness Exam/807 Q’s and A’s
Where are Beta 1 receptors found? - -Heart and Kidneys
-Stimulation of Beta 1 receptors result in an increase of what? - -Heart:
Inotropy, Chronotropy, Dromotropy
Kidneys: Renin-Angiotensin-Aldosterone System = Vasoconstriction =
Increase blood pressure

right atrium, is typically supplied by the Right Coronary artery, and fires at a
rate of 60-100 bpm. - -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? - -P wave
-Carvedilol (Coreg)
Metropolol (Lopressor)
Atenolol (Tenormin)
Propranolol (Inderal)
Bisoprolol (Zebeta)
Acebutolol (Sectral)
Comolol (Brevibloc) - -Beta Blockers - used for blood pressure and cardiac
problems
-Epinephrine
Norepinephrine
Vasopressin
Dopamine
Phenylephrine
Dobutamine - -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. - -Relative Refractory
Period
(Partial flush of the toilet)
-Treatment for Beta Blocker Overdose - -Glucagon: 1-5mg IV/IO (1st Line
Drug)
,Calcium Chloride: 500mg - 1g IV/IO
-Swelling of affected limb, pain and tenderness, inflammation/redness, warm
to touch on affected limb, pain on dorsiflexion (Homan Sign) are all signs of?
- -DVT
-Treatment of DVT - -Supportive Care, Position of Comfort, Establish IV,
Cardiac Monitor, 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. - -Coronary Perfusion
-Tachycardia, Difficulty Breathing, Diminished Lung Sound, Pulse Quality
Changes, and unequal chest rise are early signs and symptoms of? - -
Tension Pneumothorax
Air is entering the pleural space but cannot escape. Positive pressure
ventilation can make it worse.
-Criteria for Unstable Dysrhythmia - -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? - -Cardiac
Tamponade
-Hypotension, SOB, Lightheadedness, Chest Pain, Syncope, Palpitations,
Extremity Swelling, and Muffled heart sounds are signs and symptoms of? - -
Cardiac Tamponade
-Indications for Dopamine - -Cardiogenic Shock
Distributive Shock after fluids
Hemodynamically significant Hypotension
Symptomatic Brady (2nd Line drug)
-AHA Guidlines for Terminating CPR efforts in field(4) - -Arrest was not
witnessed
,No bystander CPR was administered
ROSC was not achieved after complete
ALS care in the field
No shocks were administered
-Time frame that starts at the patient contact by EMS and ends with
definitive therapy of catheter passing through lesion of coronary vessel. - -
EMS-to-Balloon-Time
-Time from patient entering ED to catheter passing through lesion of
coronary vessel. - -Door-to-balloon-time
-Time from patient entering ED to fibrinolytic therapy administration. - -
Door-to-needle-time
-Time frame for door-to-balloon - -<90mins
-Time frame for door-to-needle - -<30mins
-Principle symptom of Coronary Artery Disease or Acute Coronary Syndrome
that occurs when supply of O2 is to the myocardium is insufficient to meet
demand and cells become ischemic? - -Angina Pectoris
-Chest pain that occurs at rest and is caused by coronary artery vasospasm?
Risk for Dysrhythmia, MI, Heart Block and Death - -Prinzmetal Angina (PA)
-Which electrolyte flows into cardiac cells to initiate depolarization? - -
Sodium (Na+)
-Which electrolyte flows out of cardiac cells to to initiate repolarization? - -
Potassium (K+)
-Which electrolyte plays a major role in depolarization of pacemaker cells to
maintain depolarization and myocardial contractility? - -Calcium (Ca++)
-Which electrolyte stabilizes cell membrane and acts in concert with K+ and
opposes actions of Ca++? - -Magnesium (Mg++)
-Hypokalemia results in? - -increased myocardial irritability
-Hyperkalemia results in? - -decreased automaticity/conduction
-Hypocalcemia results in? - -decreased contractility and increased irritability
, -Hypercalcemia results in? - -Increased contractility
-Hypomagnesemia results in? - -decreased conduction
-Hypermagnesemia results in? - -increased myocardial irritability
-Four properties of the Cardiac Conduction System - -Excitability - cells
respond to electrical impulse
Conductivity - cells pass impulse to one another
Automaticity - hearts ability to generate its own electrical impulse
Contractility - hearts ability to contract when stimulated
-Affects of RCA occlusion in terms of the SA node ischemia? - -SA node
becomes ischemic = slower firing rate (<60-100) or cease fire completely
causing another automaticity foci to take over such as AV (40-60) or Purkinje
(20-40).
-Which electrolytes are responsible for depolarization? - -Sodium and
Calcium influx
