Janice (Cardiac) Flashcards
(15 cards)
Detects defects in the intrinsic thromboplastin system. Used to monitor anticoagulant/heparin therapy.
PTT (partial thromboplastin time)
List some risk factors to reduce future heart problems:
high blood pressure, high cholesterol, obesity and overweight, smoking, controlling diabetes
A heart attack caused when a blood clot suddenly forms, completely blocking an artery in the heart. This can result in damage that covers a large area of the heart and extends deep into the heart muscle. The priority in treating this type of heart attack is to open the artery quickly, saving as much heart muscle as possible.
STEMI
Dietary Approaches to Stop Hypertension. This includes foods low in saturated fats, total fat, and cholesterol. A diet high in fruits, vegetables, and low-fat dairy products. Keeping sodium intake to <1500mg (approx. 2/3 teaspoon) per day. Aim for 25-50 grams of fibre per day. Keeping a diary of eating habits allows the patient to identify where he/she can start making changes. What diet is being explained?
DASH
Whats the equation for cardiac output?
Stroke Volume X Heart Rate
_____ is the depolarization of the ventricles
QRS complex
An isoenzyme found in cardiac muscle. It increases in 4-6 hours after chest pain occurs and begins to decline in 12-24 hours.
Creatine kinase-MB (CK-MB)
Has an extraordinarily high specificity for myocardial cell injury. They elevate sooner and remain elevated longer than many of the other enzymes that represent myocardial injury.
Troponin T
What are some risk factors for type 2 diabetes?
Obesity, High glucose levels, high bp, genetics, Lack of exercise.
In the pancreas, ____ cells detect the high glucose levels and respond by secreting insulin.
Beta
Test taking about 15 minutes, patient isn’t to smoke, drink or take beta blocker for at least 2 hours prior to test. Test is done using a treadmill or stationary bike to increase patients heart rate until goal is reached or chest pain experienced. Monitoring the patients BP, HR, and Breathing.
Stress Test
A test that checks how your heart is functioning by measuring the electrical activity of the heart. With each heart beat, an electrical impulse (or wave) travels through your heart. This wave causes the muscle to squeeze and pump blood from the heart. By measuring how long the electrical wave takes to pass through your heart, your cardiologist can determine if the electrical activity is normal, fast or irregular. By measuring the amount of electrical activity passing through your heart, your cardiologist may be able to determine if your heart is enlarged or overworked.
ECG
If your patient ECG showed ventricular fibrillation, what would be the appropriate actions?
CPR, Defibrillation
What is the nurses responsibility with ECG’s?
- Setup
- Monitoring
- Recognition (Noticing rhythm)
- Intervention
- Education & Practice
Which is more common NSTEMI or STEMI?
STEMI
