Study Notes
- Diagnostic tests for heart conditions: Cardiac Enzymes, Electrocardiogram (ECG), Stress Tests, Echocardiogram, Nuclear Scans, Invasive Studies (Cardiac Catheterization)
- Cardiac Enzymes: proteins and enzymes released into the blood by damaged cardiac cells, help identify recent Myocardial Infarction (MI), examples include Creatinine Kinase, Lactic Dehydrogenase, Troponins I and T, Myoglobin
- ECG: measures the graphic recording of electrical activity of the heartbeat, each beat an electrical impulse travels through the heart
- Stress Tests: measure the heart’s electrical activity during exercise, blood oxygen level, blood pressure, and heart rate monitored, patient exercises for 10-15 minutes
- Echocardiogram: uses sound waves to view the heart and blood flow, provides a graphic outline of the heart, hand-held wand provides pictures of the heart’s valves and chambers, evaluating the pumping action of the heart
- Nuclear Scans: uses radioactive substances to see structures and function in the body, detects Myocardial Damage, special camera detects radioactivity, small amount of radioactive material administered before test
- Cardiac Catheterization: long, thin tube (catheter) inserted into an artery or vein, threaded through the blood vessel to the heart, provides structural abnormalities, risk of bleeding around the puncture, abnormal heart rhythms, blood clots, infection, allergic reaction to dye, stroke, heart attack, perforation of a blood vessel
- Nursing Considerations: Allergy to Shellfish or Iodine, NPO prior to procedure, consent, routine pre-op procedures, maintain bedrest until fully awake, lie flat up to 8 hours, prevent swelling, bruising, bleeding, apply pressure to incision to prevent bleeding and promote healing, monitor vital signs, pedal pulses, check for hemorrhage
- Diagnostic Blood Studies: Complete Blood Count, Coagulation Studies, Blood Cultures, Erythrocyte Sedimentation Rate, Lipid Profile.
