The blood pressure is usually high when blood leaves the small arteries and enters the capillaries.
A blood transfusion - is giving a patient a quantity of blood to replace any that's been lost though an accident or injury. A small sample of the patient's blood is analysed to determine the blood group & type. This is 'cross-matched' with blood of the same type stored at the hospital. A unit (or 'bag') of blood is hung above the patient from a metal stand, and a needle leading from the bag is inserted into a vein in the patient. A combination of gravity, and the patient's heartbeat drains the blood from the bag into the body. The bag is replaced when empty or the donation is stopped once the patient's blood pressure returns to normal.

Yes it does cause a small rise in blood pressure.
Petechiae are small red spots on a patient's skin due to a blood clotting disorder.
EMT's need to be prepared for the unexpected. Small clues in a patient's history can make a huge difference in their care. A patient with a headache could be having a migraine, a stroke, an impending seizure, or a thousand other ailments. Knowing what problems the patient has encountered in the past helps the EMT to narrow down the possibilities of what is wrong. A patient regularly taking Excedrine (R) Migraine might be having another migraine. A patient who historically has high blood pressure but is out of their medication could be at a high risk for a fatal stroke. A typically healthy patient with extremely low blood pressure could be at risk of shock or cardiac arrest, whereas an elderly patient whose blood pressure is normally high but is currently "textbook normal" could be suffering from a multitude of issues. What is normal for one patient is deadly for another; the patient's history helps to figure this out.
