Generally, on should keep his blood pressure under control.
Factors responsible for increase in blood pressure like, tension, anger should be kept at bay.
As for as diet is concerned, diet low in salt and low in fats and high in fruits and vegetables should be given to stroke patient.
Third part of question first aid
at home, these patients should be immediately shifted to ER,at home, try to maintain his /her airway by opening his mouth and keeping his tongue forward, not allowing it to fall back.
Not feeding him anything orally at home.
Transport him/her to hospital in lateral position.
