Rationale 1: There are some specific guidelines set forth by the National Institutes of Health that can be used to classify a client's blood pressure as "normal," "prehypertension," "stage I hypertension," and "stage II hypertension.".
Rationale 2: A normal blood pressure is actually less than 120 (systolic) and less than 80 (diastolic).
Rationale 3: A client with prehypertension will have a blood pressure of 120–139 (systolic) and 80–89 (diastolic).
Rationale 4: This is an accurate response. The client with stage II hypertension will have a blood pressure greater than or equal to 160 (systolic) and greater than or equal to 100 (diastolic).
