Ultimate Questions and Answers
1. If bleeding is in pericardial sac, what must be ruled out? - Answer: If bleeding is in pericardial
sac, cardiac tamponade must be ruled out.
2. Oxygen reperfusion injury - Answer: Oxygen promotes systemic vasodilation and is the source of
toxic metabolites and had been associated with poor outcomes.
3. 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.
4. 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.
5. 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.
, 6. 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.
7. A fib to WPW syndrome is common. What does the ECG show in WPW? - Answer: Short PR
interval.
Inverted T waves seen in WPW.
8. INR 5-10 and uncontrolled bleeding treatments. What to administer? - Answer: Fresh frozen
plasma or prothrombin complex concentrate.
9. Signs of instability for possible cardioversion - Answer: Hypotension.
Mental status changes.
Chest pain.
SOB.
Crackles.
Cold clammy skin.
10. Monomorphic ventricular tachycardia and hyperkalemia treatment? - Answer: Calcium to
prevent ventricular fibrillation.
Calcium stabilizes cardiac heart tissues.
11. Idiopathic cardiomyopathy signs and symptoms - Answer: SOB, 4+ edema, O2% decreases, EF
<40% or less, lack of energy, S3 and S4 heart sounds.
12. Signs of pulmonary edema - Answer: HTN.
Heart failure with EF 15%.
S3 heart sounds.
