Hello mercury manometer is always more accurate than the digital one....BP readings may vary with postures...anxiety...stress...physical activity let her check her BP continuously in morning and evening for 3 to 4 days even after this if the BP readings are more she has to be started with antihypertensive consult physician for further evaluation and treatment I hope this helps to solve your problem.
