Mrs. Jones is pulseless and has a rhythm with visible P waves, narrow QRS complexes associated with P waves, and a rate of 130 beats/min on the cardiac monitor. Which of the following would best describe the rhythm?
Pulseless electrical activity
The patient with a pacemaker shows a spike that is not followed by a QRS. This is called:
Failure to capture
The hemodynamic effects of a fast heart rate may be caused in part by:
decreased ventricular filling time and increased myocardial oxygen consumption
In order for a diagnosis of wandering atrial pacemaker (multifocal atrial rhythm) to be made, the rhythm must have:
a heart rate of at least 100 bpm, a varying PR interval, at least three configurations of P wave
The release of the electrical charge in a cardioversion is synchronized by the ____ wave.
Paddle placement for anterior defibrillation:
second intercostal space, right sternal border and fifth intercostal space, left midclavicular line
The patient is diagnosed with abrupt onset of supraventricular tachycardia (SVT). Which of the following medications has a short half-life and is recommended to treat symptomatic SVT?
The initial treatment of a client with bradycardia (HR 40 bpm), a BP of 84/50, and frequent PVC's is:
Atropine 0.5 to 1mg IV push
A 74-year-old woman is admitted to the coronary care unit with an inferior wall myocardial infarction. She develops symptomatic bradycardia with premature PVC's every third beat (trigeminy). You prepare to administer
The drug of choice for patients with frequent ventricular ectopy (dysrhythmias) is:
A patient has been successfully converted from V-tach with a pulse to a sinus rhythm. Upon further assessment it is noted that she is hypotensive. The appropriate treatment for her hypotension may include:
Dopamine infusion, Normal saline infusion
A patient is admitted to the CCU with bradycardia and 39 bpm with frequent PVC's. Upon assessment you note that she's lethargic and has complained of dizziness for the past 12 hrs. Which of the following treatments are acceptable treatments for symptomatic bradycardia?
Atropine, Epinephrine, Transcuteaneous pacemaker
Which code drugs can be given safely through an endotracheal tube?
Atropine, Epinephrine, Vasopressin
Which of the following statements about defibrillation are correct?
Early defibrillation (if warranted) is reommended before other actions, It's not necessary to synchronize the defibrillation shocks, Paddles/patches can be placed anteriorly and posteriorly on the chest
The nurse is caring for a patient in the early stages of septic shock. The patient is slightly confused and flushed, with bounding peripheral pulses. Which hemodynamic values is the nurse most likely to assess?
Low systemic vascular resistance and high cardiac output
The nurse is caring for a patient admitted with severe sepsis. Vital signs assessed by the nurse include BP: 80/50, HR: 120, Resp: 28, Temp:102 Degrees F, and a right arterial pressure of 1mmHg. Assuming Physician orders, which intervention should the nurse carry out first?
Isotonic fluid challenge
Used to treat high BP and heart failure; causes dry cough, loss of taste, proteinuria, hyperkalemia; End in: PRIL
Angiotensin II Receoptor Blocker
Vasodilates arterioles by blocking the effects of Angiotensin II, enhance RENAL clearance of sodium and water; Treats high BP; causes URI, insomnia, visual changes, GI/GU effects
Calcium Channel Blockers
Relaxes smooth muscle to provide vasodilation and affects cardiac muscle to reduce HR and SV; Used for Angina, Dysrhythmias, HTN; causes fluid retention, rash/flush, light-headedness
Increases the excretion of sodium and water and controls high BP and fluid retention; Used for edema associated with HF, HTN, Renal impairment (Furosemide); Cause hearing loss/tinnitus and electrolyte disturbances
Lowers BP by dilating peripheral blood vessels, reducing peripheral resistance; Used for Raynaud's disease, HTN; Causes orthostatic hypotension, fainting
Reduce the workload of the heart by blocking the sympathetic conductance at the beta receptors of the SA node and myocardial cells, thus decreasing the force of contraction and causing a reduction in HR; Used for HTN, Angina, Dysrhythmias, MI; Ending: OLOL; Causes bradycardia, increased cholesterol and glucose levels
Type of diuretic; Used for edema caused by HF and pregnancy, HTN, Diabetes insipidus; (Chlorothiazide, Chlorthalidone, Hydrochlorothiazide); Causes Electrolyte disturbances, lethargy (too much can lead to coma)
hormone that causes vasoconstriction (which makes the BP higher)
hormone that vasoconstricts; causes the release of aldosterone from adrenal cortex (which causes body to hold on to fluids)
For V-Fib, V-Tach, Rapid atrial dysrhythmias; Use for cardiac arrest IV push; SLOWS THE HR
Treats SVT's; SLOWS THE HR (in AV node) may cause asystole for 15 seconds
Treats symptomatic bradycardia/pulseless electrical activity; Speeds up HR (sa and av node) IV push; causes tachycardia; if it doesn't work do transcutaneous pacing
Used for frequent Ventricular ectopy (dysrhythmias)
Thickest, most muscular section of the heart
Where does the Right Coronary Artery perfuse to?
Right Atrium, Right Ventricle, Posterior Left Ventricle
Where does the Left Coronary Artery perfuse to?
Anterior/Lateral walls of Left Ventricle, Apex of Left Ventricle, Left Atrium
Blood flow through Coronary Arteries and Heart?
Coronary Veins (with CO2 & waste)-->Coronary Sinus--->Right Atrium
Where are the Right and Left Coronary Arteries Located?
They branch off the Aorta
Tricuspid and Mitral Valve closing
Pulmonary and Aortic Valves closing
Class III antiarrhythmic drug?
What electrolyte is VERY potent?
B-type Natriuretic Peptide; Neurohormone secreted by the heart in response to Ventricular expansion (high levels may suggest HF)
Inflammation of the wall of a vein with associated thrombosis, often occurring in the legs during pregnancy
ANTIARRHYTHMIC; Strengthens contractions of hearts, slows conduction of Atria to Ventricles (used for A-Fib, A-flutter, A-Tachy); cardiac glycoside (0.8-2.0) Make sure HR is above 60bpm; make sure kidney and liver are functioning
Used for HF, irregular HR; helps circulation, pumps stronger, relieves swelling (cardiac glycoside)
What procedure can be done for Angina?
S/S of Digoxin toxicity?
Nausea, light-headedness, VISUAL CHANGES (yellow, green auras)
Pericardial friction rub, CHEST PAIN, fast/trouble breathing, orthopnic position
Notify doctor if output is less than 500mL in 24 hour period (any signs of infection)
Inflammation of heart muscle, bad cardiac output, tachy pulse, gallops, enlarged heart
When matching a donor to a recipient for a heart transplant what should be considered?
Same blood type, heart, and body size (Assess for fever, rejection, give immunosuppressant)
Thrombolitics vs. antiplatelets, anticoagulant
Thrombolitics blow up blood clots, antiplatelets/anticoagulant prevent clot from happening
T wave is what?
Repolarization (filling back up with blood)
QRS is what?
Ventricular depolarization (contraction)
Atria can't fill with blood and HR is over 350
When patient has neurogenic shock, what physiologic changes occur?
Sympathetic Nervous System fails
