   • They account for 87% of all strokes and are usually caused by an occlusion of an artery to a region of the brain.
   • They account for 50% of all strokes and are caused by an occlusion of a vein to a region of the brain.

    • AV block

Answer 1

1. The correct option is Headache and blurry vision . Acute coronary syndrome is an emergency condition in which there is an acute onset of myocardial infarction that causes myocardial ischemia . Signs and symptoms include :-

- chest pain

- pressure in the center of the chest

- shortness of breath

- indigestion

- nausea

- anxiety

- pain radiating to jaw, neck, shoulder ,left hand

- heartburn

- sweating

- lightheadedness

2. The correct option is Asystole

Indications of TCP :-

- hemodynamically unstable bradycardia (AMS, hypotension, s/s of shock)

- Bradycardia unresponsive to atropine therapy

- Unstable clinical condition likely due to the bradycardia

- For pacing readiness in the setting of AMI

- Bradycardia with symptomatic ventricular escape rhythms

- Used as bridge until transvenous pacer can be established

3. The correct option is abdominal tenderness.

5 serious signs and symptoms of unstable tachycardia are :-

- Hypotension

- Ischemic chest discomfort

- Acute heart failure

- signs of shock

- acutely altered mental status

4. The correct option is- they account for 80% of all strokes . Ischemic stroke is thrombotic and embolic . Accounts for 80-85% of strokes .
