I am a Student nurse in NZ.
We have learnt that the expected range for blood pressure was 100-130/60-90 mmHg.
When I took my clients blood pressure (86 y.o), I got systolic pressure as 170. When I said this was a bit high (she is a previous doctor), she said that was expected, and that systolic should be 100 + clients age. My clinical lecturer agreed that it wasnt too high,
Is this correct?
