No worries
Life Support is fine for her, then.
However, that is SEVERE hypertension - she not only has severe diastolic hypertension, but systolic hypertension. For blood pressure that high I actually would recommend that she DOES get blood pressure medication, if only until it comes back down to even mild hypertension.
Stress can cause an increase in blood pressure. So can "white coat syndrome". I recommend getting it checked again in about a week or something - if you can, on a daily basis first thing, resting for about a week, and note any fluctuations.
If her blood pressure is really that high without another cause, then she will have to be careful when exercising - if she uses this to try and increase her fitness to decrease her blood pressure.
