Welcome to Healthcare Magic
You probably haven't understood the BP measurement. 150/48mmHg indicates that the SYSTOLIC BP is 150 and the DIASTOLIC BP is 48. They both are different measurements and not the same. Anyways, her systolic BP is above range, it should be within 140 and her diastolic BP is lower, as it should be above 60. Proper fluid management would help in this provided she has no heart disease
. Consult her Doctor and see if her BP is picking well after treatment.
