| Question | Answer |
|---|---|
| What is the pathway of blood flow through the Heart? | SVC/IVC, R Atrium, tricuspid, R Vent, pulmonic valve, pulmonic artery, Lungs, Pulmonic vein, L atrium, L Vent, aortic valve, aorta, body, SVC/IVC |
| What is the order of valves in the heart? | Tricuspid, Pulmonic, Mitral, Aortic (TPMA) |
| What is the order of heart sounds? | Aortic (R 2nd), Pulmonic (L 2nd), Tricuspid (L 4th), Mitral-Apex-Apical (L 5th) |
| Where are S1 and S2 heard? | 4th and 5th intercostal space (easier to hear if pt is on their L side) |
| If pt has heart damage where can the sounds be heard best? | Laterally |
| What is preload? | The Amt of blood return to the heart (mostly R side) |
| What is after load? | the pressure in aorta and peripheral artery that the L Vent has to pump against to get blood out of heart to body. Increased BP is added resistance that L Vent has to pump against. |
| If you increase the volume going back to heart (preload) what does that due to workload? | Increases work load |
| What can Increased BP lead to in terms of the heart? | CHF and PE- if you increase after load this decreases CO and wears out heart muscle. |
| What is the formula for CO and what affects it? | SV=HRxSV -tissue perfusion -changes dep on bodes needs (if your HR inc then your SV with inc and then your CO will inc) -HR (if D or I too much CO drop) -BV (less volume less CO) -D contractibility (meds, MI, Muscle Dz) |
| What is SV? | amt of blood pumped out of vent with each heartbeat |
| Left Ventricle equals... | CO (cardiac output) |
| What happens to CO if you Increase after load? | Decrease (too much pressure to pump against) |
| What are some complications of Decreased CO? | - chest pain, wet lungs, SOB, cold/clammy skin, D UO, D peripheral P -Bradycardia (D HR) is ok if CO is still functioning well (can't have any of above sx) -NO CO = PULSELESSNESS/V-Tach/V-Fib |
| What is ANGINA? | Decreased BF to myocardium that leads to ischemia or necrosis -Can be stable (know factors/tx) or unstable (unknown factors/tx) |
| What is ISCHEMIA? | -Temporary pain and pressure in chest usually caused by CAD -Pain is caused by D O2 usually do to EXERTION -Tx: REST and NITRO |
| How does NITRO work? | -Dilation of Veins and Arts (D pre/after which D workload on Heart) -Dilation of Coronary Art (I BF to heart muscle brings O2 & stops pain) -1 q 5 min x3 ( if this doesn't work go to ER) will D BP but should go back up-never leave pt until stabilized |
| How do BB work? | -Antihypertensive - slows HR and D contractibility -D workload which D CO -Blocks Beta receptors on heart that accept catacholemines (NE, Epi) |
| How do CCB work? | -antihypertensive -dilate Coronary Art (more O2 goes to heart muscle) |
| Why do ASA's help with ANGINA? | prevents blood from sticking together in case they are actually having an MI (chewable is best bc it works fast) -stops clot from forming 81-325mg |
| What are some NSG MGT for ANGINA? | -NO isometric exercises (no strenuous exercises on test!!) -NO caffeine/drugs/overeating/smoking (Increases HR) -wait 2 hrs after eating to exercise -avoid Temp extremes -NItro propholaticly (will be dizzy bc D BP, have pt sit down SAFETY) |

| What does MYOGLOBIN do? | -not specific to dx ACS/MI/Unstable Angina -GOOD to R/O ACS/MI/Unstable Angina -Increases w/in 1 hr, peaks at 12 hrs |
| What major ARRHYTHMIA can lead to sudden DEATH? | V-Fib (No CO bc tissue is dead so it can't be perfused) -DEFIB the V-FIB |
| What are some TX for V-FIB? | -1st DEFIB -2nd Epi (vasopressor) -3rd Amiodorone (antiarrythmic- used when resistant to tx, can be given to prevent 2nd) or Lidocaine (D irritability of heart) -TOXICITY = ANY NEURO CHANGES |
| Tx of MI? | -Oxygen -ASA (165-325mh) -NITRO -MORPHINE (if pain not relieved by Nitro) -HOB UP -FIBRENOLYTIC (breaks up clot blocking BF to heart muscle) |
