- TIMI score
Answer: a prognostic tool for patients with unstabe angina or NSTEMI
Categorizes patient's risk of death and ischemic events & helps clinicians with therapeutic decision-making.
A point of one for each of the following:
1) apsirin use in the last seven days 2) ST changes of at least 0.5 mm on EKG 3) Elevated serum cardiac biomarkers 4) Age greater than 65 5) known CAD (coronary stenosis greater than or equal to equal to 50%) 6) At least two angina episodes within the last 24 hours
7) At least three risk factors for CAD such as: HTN, DM, current cigarette
smoker, family hx of premature CAD (CAD in male first-degree relative or father less than 55, or female first-degree relative or mother less than 65)

Answer: Severe burns, crush injuries, & renal failure.
5. Glasgow Coma Scale:
- What to do with a patient with a GCS of 8?
Answer: Intubation
- Thoracic injuries secondary to blunt chest
Answer: The plain CXR remains the standard initial diagnostic remains the
standard initial diagnostic study for the evaluation of chest trauma in a hemodynamically stable patient.CXR in blunt trauma patients are usually taken in the supine position initially until unstable spinal fractures have been ruled out. Then, it is important to get a PA view to appropriately evaluate for small hemothorax, pneumothorax o diaphragm injury.

Answer:
1) Volume expansion with IVF (0.45% NACl or 0.9% NaCl at 250-500 ml/hour) --Bolus anywhere from 2-4 liters of fluid prior to starting IV insulin 2) Check potassium levels is checked and replace as needed 3) An insulin drip will need to be started at 0.1 unit/kg/hour --after serum glucose 4) Check serum pH level to determine if bicarbonate is needed in the fluids 5) When serum glucose is at a reasonable level 200 mg/dL), the fluids should be changed to D5 0.45% NaCl & the insulin drip is weaned.
