Card Set Information
CCRN cardiac review
What are the three most common causes of Metabolic Acidosis?
ARF, Lactic Acidosis & DKA
Why is diastolic BP so important?
It shows what the capillary blood flow is.
What is pulse pressure a measurement of?
Left ventricular performance
What is the renal dose of Dopamine?
Trick question- there is no renal dose. 2.5mcgs is a vasodilating dose.
What happens to HR and ECG in a RCA- IWMI(Inferior wall MI)?
Bradycardia and Heart block
What determines Ventricular Function?
Preload, Contractility and Afterload
What should you think when you hear a S3 heart sound?
Emergency- patient if volume overloaded
What should you think when you hear a S4 heart sound?
Every person who has a MI will have this sound but it can only be heard when the patient is in SR
What is normal PA pressure?
What is the normal Wedge(PWCP)?
What is normal CO?
What is normal CI?
What is normal CVP?
What determines SVO2?
CO/CI, H&H, Oxygenation and Metabolic Demand
What leads should be monitored?
Lead II and MCL1 or V1
Why should you monitor 2 leads?
Location and "p"wave analysis
What ECG changes appear in Hypokalemia?
Flat T wave with prominent U wave, ST segment flattening, Prolonged QT interval and ST segment depression
What ECG changes appear in hyperkalemia?
>5.5- tall, narrow, peaked Twaves
>6.5- QRS widens
>8- Wide QRS and P wave barely visable
What is the treatment for Hyperkalemia?
Remove= Kayexelate or HD
Shift K= insulin and D50, NaHCO and Ca
The calcium is given to protect the heart
What ECG changes appear in hypocalcemia?
Prolonged QT and Prolonged ST segment
Torsades de Pointes
What ECG changes appear in hypercalcemia?
agonal or asystole
Shortened QT and ST segment
What ECG changes appear in hypomagnesaemia?
Torsades de Pointes
-broad, flattened Twave
What ECG changes appear in hypermagnesaemia?
agonal to asystole
-PR, QT prolonged
What is CAD?
Flow limiting lesions
What is the number 1 risk factor for CAD?
What are the clinical manifestations of CAD?
HF, Angina, Unstable Angina, AMI, Sudden death
What are the functions of an IABP?
Increases coronary perfusion
So in increases myocardial oxygen supply and decreased demand
What is an absolute contraindication for an IABP?
What do you monitor for with an IABP?
What are the 6 P's of the vascular assessment?
On an ECG what leads show an inferior MI?
II, III, and AVf
How is a STEMI diagnosed?
Clinical presentation, ECG, enzymes
What does ST elevation in all leads mean?
What are the clinical presentations of Left Ventricular failure?
Tachypnea, dyspnea, orthopnea, PND
Left sided S3
What are the clinical presentations of Right ventricular failure?
Heave at sternum
Anorexia, nausea, vomiting, abd pain
Right sided S3
What is the management of an Aortic aneurysm?
Repair- stent or surgical
What does a ST segment depression show?
What does an ST segment elevation show?
Current of injury
