Flashcards in Test 1 Deck (45)
Normal Cardiac Output (CO)
End diastolic VOLUME that stretches the right or left ventricle of the heart
PRESURE/RESISTANCE against which the heart must work to eject blood during systole
Muscle function presence
Normal Cardiac Index (CI)
Mean Central Venous Pressure (CVP) in right atria
(2 x diastolic + systolic)/3
Phlebostatic axis is where?
4th intercostal space, midaxillary line
Dicrotic Notch on wave form represents:
Closing of aortic valve
Pulmonary Artery Catheter (AKA Swan Ganz) measures:
Left heart pressures
Pulmonary artery diastolic pressure (PAD, PAOP) represents pressure on which side of the heart?
Pulmonary artery systolic pressure (PAS) represents pressure on which side of the heart?
What causes increased CVP?
Over-hydration, HF, positive pressure breathing (anything ventilator related)
What causes decreased CVP?
Hypovolemia, negative pressure breathing (retractions while breathing)
Normal Pulmonary Artery Pressure
Right ventricular pressure
Normal PAOP (Wedge pressure)
What is the clutching of the chest accompanied with chest pain called?
Name and describe the three types of angina
Crescendo: pain with minimal exertion, no enzyme change
Variant (Prinzmetal): caused by vasospasm
What is the clinical difference between Non-ST-segment elevation ACS and Non-ST-segment elevation MI?
There is a presence of cardiac enzymes in NSTEMI (troponin-death of cardiac tissue).
What is the difference between a STEMI and NSTEMI?
-Clot has fully occluded coronary artery
-ST segment elevation
-Elevated enzymes (super high)
-Clot has partially occluded
-No ST segment elevation
What arrhythmia is common with right coronary artery occlusion?
Name 6 nursing interventions for decreased cardiac perfusion:
O2, ASA, morphine, NTG, continuous EKG, anxiety reduction
What are supportive therapies for post-MI hypothermic Tx?
Labs- Potassium (hypokalemia is treated)
Shivering- use of paralytics to prevent
How do you know TPA has worked?
-Arrhythmias (Vtach, PVCs, Idioventricular)
-CK levels increase ("washout")
PCA complications (8)
Allergic reactions, arrhythmias, CA rupture, re-occlusion, bleeding in groin area, CVA, renal issues (due to contrast dye), oversedation
