Types of acute coronary syndrome (ACS) - Answer ST-elevation ACS: acute chest pain and persistent (>20 mins) ST-segment elevation. Most develop ST-elevation myocardial infarction (STEMI). Non-ST-elevation ACS: acute chest pain without persistent ST-segment elevation. - unstable angina: normal troponin levels as no necrosis (although occasionally there can be minor rises in troponin signifying increased risk of subsequent cardiac events). - non-ST-elevation myocardial infarction (NSTEMI...

What is UA? - Answer Unstable Angina, a type of ACS -chest pain, with no cardiac enzymes -no or transient ischemic ECG changes (ST depression, T wave inversion) Treat: GAP-BAS What is NSTEMI? - Answer Non-ST Elevated Myocardia Infarction, a type of ACS (Heart Attack/Blockage) -chest pain with positive cardiac enzymes (troponin I/T) -no or transient ischemic ECG changes (ST depression, T wave inversion) Treat: GAP-BAS What is STEMI? - Answer ST-Elevated Myocardial Infarction...

Which descriptions of chest pain would be associated with ACS? - Answer - Pain that may be intermittent - Pain that feels like pressure, squeezing, tightness, aching or heaviness - Pain that radiates to one or both arms - Pain lasting longer than 3 to 5 minutes A patient presents to the ED with s/sx suggestive of ACS. The 12-lead ECG shows T-wave inversion < 2 mm. To which clinical category would you assign this patient? - Answer Low- or intermediate-risk NSTE-ACS Which condition...

Rutherford's Gold Foil Experiment - Answer proposed that atoms consist of a tiny, massive, positive nucleus surrounded by electrons nucleus - Answer contains all the positive charge and nearly all the mass of the atom James Chadwick - Answer discovered the neutron cathode rays - Answer move from negative electrode to positive electrode (like electrons in a voltaic cell) Thompson's Cathode Ray Experiment - Answer discovery of the electron (also the discovery that atoms are...

When naming carboxylic acids - Answer find the longest continuous carbon atom chain contianing the carboxylic acid group What is the prefix in carboxylic acids? - Answer -oate To name an ester, - Answer identify the alkyl group that is in the 'alcohol' portion of the molecule and name it; then identify the acid part of the molecule. The ester is named with the alkyl part first, and the acid part is named as a carboxylate. The terms ortho, meta, and para are used when benzene der...
