How to to put together this function below

[Pat Miller]

How put together this formula to determine if my blood pressure is in normal
range:

If =<120 return "Normal"
If between 121 and 139 return "Pre-hypertension"
If between 140 and 159 return "Stage One"
If greater than or equal to 160 "Stage Two"

Thanks in advance.

One way:

=LOOKUP(A1,{0,"Normal";121,"Pre-hypertension"; 140,"Stage One"; 160,
"Stage 2"})

=IF(A1<121,"Normal",IF(A1<140,"Pre-hypertension",IF(A1<160,"Stage One","Stage
Two")))
