Question 1: Troponin earliest increase, peak and return to normal

Answer:

3-4 hours, peaks in 4-24 hrs and returns to normal 1-3 weeks

Question 2: Medications to treat ventricular dysrhythmias

Answer:

Lidocaine, Beta blockers, amiodarone (drug of choice for v-tac)

Question 3: What drug(s) do you use for Asystole

Answer:

Epinephrine, and atropine

Question 4: Cardiac Tamponade S/S

Answer:

Life threatening need stat interventions. S/S fullness within the chest, substantial or ill defined pain.sob, massive JVD, falling systolic blood pressure, narrowing pulse pressure, rising venous pressure (increased JVD) and distant heart sounds

Question 5: Narrowing pulse pressure would be seen in which patient

Answer:

Tamponade, also massive JVD

Question 6: The drug used to Chemicaly Cardiovert SVT is

Answer:

Adenosine Question 7: CVP normal value:Wedge pressure:PAP

Answer:

CVP:0-4 Wedge pressure:8-15 PAP 20-30/5-15

Question 8: Right Heart Failure (chronic condition)

Answer:

JVD, Dependent Edema, right upper gastric pain(Right heart handles systemic blood return)

Question 9: Left Heart Failure

Answer:

Bibasilar fine crackles, dyspnea, tachycardia, S3 and S4 heartsounds,fatigue, hemoptysis, non-productive cough, cool pale skin, PMI displaces toward the left anterior axillary line Question 10: Aortic Regurgitation: S/S

Answer:

Forceful heartbeats in head and neck, arterial pulsations that are visible or palpable at the carotid or temporal arteries. Exertional dyspnea, fatigure, progressive s/s of left ventricular failure includie breathing difficulties, orthopnea, PND.

Question 11: Rhumatic Fever

Answer:

Caused by strep Question 12: IF there is a P-wave, the rhythm will be one of theses Sinus Rhythms:

Answer:

Sinus Rhythm: Normal Sinus Rhythm, Sinus Bradycardia or Sinus Tachycardia

Question 13: Cardiac Tamponade treatment

Answer:

pericardiocentesis, pericardiotomy (pericardial window)

Question 14: Calcium Channel Blockers

Answer:

Slows heartrate and decreases strength of contraction which decreases workload of heart. Relaxes blood vessels decreasing BP and increases coronary artery perfusion

Question 15: hypokalemia wave form changes

Answer:

U uaves after the T Question 16: Determine the Rate:

Answer:

60-100 (NSR or AJR)<60 (SB, or JR)> 100 (ST or JT)

Question 17: Nitroglycerin

Answer:

Reduces oxygen consumption to devrease ischemia and relieve pain. Vasodialator mainly in veins and reduces blood return to heart and preload is reduced. May cause a significant drop in cardiac output and B/P if pt is hypovolemic at higher doses.

Question 18: PR Interval = .12-.20 = (3 to 5 little boxes)

Answer:

= Sinus Rhythm, Sinus Brady, Sinus Tach Question 19: CABG:

Answer:

70% occlusion (60% if in the Left main). artery must me patent beyond the occlusion. Use greater saphenous vein, lesser saphenous, chephalic and basilic veins.

Question 20: S/S of Infective Endocarditis

Answer:

Osler's nodes (red, painful nodules on the fingers and toes) splinter hemorrhages, fever, diaphoresis, hoint pain, weakness, abdominal pain, new murmur, Janeway's lesions (small, hemorrhagic areas on fingers, toes, ears, and nose)

Question 21: PR Interval = <.12 (less than 3 little boxes)

Answer:

= Junctional Rhythm, nextlook at rate

Question 22: Irregular Rhythms

Answer:

A-flutter, Sinus Arrhythmia, 2 degree or 3 degree heart block, A-fib

Question 23: Nursing Diagnosis related to CABG

Answer:

Fear, Deficient knowledgeIneffective cardiac tissue perfusion, Decreased cardiac output, Impaired gas exchange, Risk for imbalanced fluid volume, Disturbed sensory perception, Acute pain, Ineffective tissue perfusion, Ineffective thermoregulation

Question 24: Endocarditis Infective Risk factors

Answer:

Risk factors: heart valve prosthesis, hx of heart disease (mitral valve prolapse), chronic dibilitatin disease, IV drug abuse and immunosuppression

Question 25: When do you cardiovert

Answer:

When you have a pulse

Question 26: Regular QRS =

Answer:

0.06-0.10

Question 27: 12 Lead EKG

Answer:

ST elevation indicates immediate myocardial injury. ST depressions indicate myocardial ischemia. Q wave forms several days after a myocardial infarction, U wave is a sign of hypokalemia.

Question 28: hypomagnesium

Answer:

Torsades de pointes
