Barron's CCRN 1."high dose" dopamine causes vasoconstriction and (C) Increase afterload: What is the primary hemodynamic effect of: Dopamine >10 mcg/kg/min (A)Increase preload (B)Decrease preload (C)Increase afterload (D)Decreased afterload (E)Increase contractility (D)Decrease contractility 2.Pulmonary HTN and cor pulmonale;
Mitral, aortic, or tricuspid insufficiency: What causes the S3 sound?
3.during diastole: When are coronary arteries perfused?
4.S3 heart sound: What may you hear before crackles when a patient
is going into heart failure?
5.Variant or Prinzmetal's Angina: What is this called?
Unstable angina with transient ST segment elevation Can occur at rest or may be cyclic (occurring at the same time daily) troponin negative Can be precipitated by nicotine, coke, or ETOH
6.RCA, inferior LV: There are changes in leads II, III, aVF....what type of
MI? 1 / 4
2 / 18
7.LAD, anterior LV: There are changes in leads V1, V3 V3, V4
8.circumflex, lateral LV: There are changes in leads V5, V6, I, aVL
9.Low lateral LB: There are changes in leads V5, V6 2 / 4
3 / 18
10.high lateral LB: There are changes in leads I aVL
11.RCA, posterior LV: There are changes in leads V1 and V2
12.RCA, right ventricular infarct: There are changes in leads V3R, V4R
13.Marked ELEVATION of troponin/CK-MB: due to miocardial stunning
when vessel opens
reperfusion arrhythmias: VT, Vfib, accelerated idioventricular rhythm (due to
stunning) resolution of ST segment deviations
Chest pain relief: What are some signs of reperfusion following
fibrinolytic treat- ment of a STEMI?
14.contact the physician. Could be coronary artery re-occlusion/stent
throm- bosis.: Your patient just had a percutaneous coronary
intervention (PCI) (stenting) less than 24 hours ago:
He is experiencing unrelenting chest pain, his EKG shows ST elevation.What should you do? What could be happening?
15.retroperitoneal bleeding is most likely. Give fluids/blood: Your patient
just had a percutaneous coronary intervention (PCI) (stenting) less
than 24 hours ago:
He is experiencing sudden low severe back pain and becomes hypotensive. What is happening?
16.>1 (get by dividing ankle pressure by brachial pressure on the
same side): what is a normal ankle-brachial index (ABI)?
17.do not elevate the affected extremity, it will decrease perfusion
Put bed in reverse trendelenburg: Your patient has PAD and just had a
bypass graft. How should you care for the extremity? How should the HOB be?
18.torsades: prolonged QT can lead to what deadly rhythm?
