Normal systolic blood pressure (BP) for a 4-year-old child is approximately
a. 72 mm Hg. c. 88 mm Hg.
b. 84 mm Hg. d. 92 mm Hg.
C
To determine the normal systolic BP in a child over the age of 1 year, you would use the following formula: 80 + (2 ? age in years). For a 4-year-old child, normal systolic BP would be computed as: 80 + (2 ? 4) = 80 + 8 = 88 mm Hg. Normal diastolic BP is generally two-thirds of the systolic BP.
