Prenatal clients are routinely monitored for early signs of pregnancy-induced hypertension (PIH).

(A) These blood pressure changes reflect only an 8 mm Hg systolic and a 5 mm Hg diastolic increase, which is insufficient for blood pressure changes indicating PIH. (B) These blood pressure changes reflect a decrease in systolic pressure of 8 mm Hg and diastolic pressure of 2 mm Hg; these values are not indicative of blood pressure increases reflecting PIH. (C) The definition of PIH is an increase in systolic blood pressure of 30 mm Hg and/or diastolic blood pressure of 15 mm Hg. These blood pressures reflect a change of 26 mm Hg systolically and 18mm Hg diastolically. (D) These blood pressures reflect a change of only 8 mm Hg systolically and 8 mm Hg diastolically, which is insufficient for blood pressure changes indicating PIH.
