EXAM QUESTIONS WITH 100% CORRECT
ANSWERS
Risk of nitroprusside administration on a patient with renal failure is? - Answer- Cyanide
toxicity.
A patient with new frequent multi-focal PVCs. Recovering from flu 2 weeks ago. What
diagnostic test is done, and what did the patient develop? - Answer- Echocardiogram.
Developed dilated cardiomyopathy from viral myocarditis.
Management of cardiogenic shock and how to decrease left ventricular workload -
Answer- Increase myocardial oxygen delivery.
Maximizing cardiac output and decreasing left ventricular workload.
Administer afterload reducers like vasodilators and improve contractility with positive
inotropic agents.
Descending aortic dissection signs/symptoms. - Answer- Descending aortic dissection
manifests with pain radiating down the back, abdomen, or legs.
Aortic valve replacement with a development of new atrial fibrillation and ventricular
heart rate of 100. What medication to administer? - Answer- Administer beta-blocker.
Digoxin, beta-blocker and calcium channel blockers are used to treat atrial dysrhythmia.
Which type of dysrhythmia is common following open-heart surgery? - Answer- Atrial
dysrhythmia.
If bleeding is in pericardial sac, what must be ruled out? - Answer- If bleeding is in
pericardial sac, cardiac tamponade must be ruled out.
Oxygen reperfusion injury - Answer- Oxygen promotes systemic vasodilation and is the
source of toxic metabolites and had been associated with poor outcomes.
Carotid artery stenosis risk factors, signs and symptoms, and priority intervention. -
Answer- Risk factors are Hypertension, Obesity, Diabetes, and hyperlipidemia.
, Signs/symptoms are transient blindness in one eye, memory loss, numbness in the
face, headache, and dizziness.
Carotid artery duplex would confirm it's presence.
Anterior Wall MI on EKG would show what? Papillary muscle rupture on an Pulmonary
Artery Occlusive pressure waveform readings look like what? - Answer- V2, V3, V4, V5:
ST segment elevation.
Large, Giant, elevated V-waves.
After a CABG and mediastinal chest tube in place, what are the signs of an acute
bleed? What is the priority intervention? - Answer- Warm bloody drainage.
Return to the OR Stop the bleeding.
cardiac tamponade occurs when what infiltrates the pericardial sac? - Answer- Blood or
fluid.
Cardiac Tamponade s/s - Answer- JVD, narrow pulse pressure, hypotension (on
inspiration), muffled heart sounds.
Chest heaviness, tachycardia, tachypnea, decreased cardiac output, decreased stroke
volume.
Afib to WPW syndrome is common. What does the ECG show in WPW? - Answer-
Short PR interval.
Inverted T waves seen in WPW.
INR 5-10 and uncontrolled bleeding treatments. What to administer? - Answer- Fresh
frozen plasma or prothrombin complex concentrate.
Signs of instability for possible cardioversion - Answer- Hypotension.
Mental status changes.
Chest pain.
SOB.
Crackles.
Cold clammy skin.
Monomorphic ventricular tachycardia and hyperkalemia treatment? - Answer- Calcium
to prevent ventricular fibrillation.
Calcium stabilizes cardiac heart tissues.
Idiopathic cardiomyopathy signs and symptoms - Answer- SOB, 4+ edema, O2%
decreases, EF <40% or less, lack of energy, S3 and S4 heart sounds.
