What would be considered normotension in a pediatric patient based on the mathematical equation SBP ≥ 90mmHg + (2xage)?

SBP of 100mmHg in a 5-year-old
SBP of 110mmHg in a 6-year-old
SBP of 120mmHg in a 8-year-old
SBP of 130mmHg in a 7-year-old

The correct answer is: SBP of 110mmHg in a 6-year-old

To determine whether the systolic blood pressure (SBP) is classified as normotension in a pediatric patient, the mathematical equation used is SBP ≥ 90 mmHg + (2 x age). For a 6-year-old, the calculation would be as follows: 1. Calculate the required SBP: - Age = 6 years - 90 mmHg + (2 x 6) = 90 + 12 = 102 mmHg. 2. Now, evaluate the SBP options against this threshold: - A SBP of 110 mmHg in a 6-year-old exceeds the calculated normotension threshold of 102 mmHg, indicating that this value is indeed normotensive for this age group. This means that a SBP of 110 mmHg in a 6-year-old falls within the acceptable range and accurately reflects a healthy blood pressure reading for a child of that age. The other options either do not fall within the appropriate threshold when calculated according to the given equation, or their values result in pressures that are not typical for their respective ages. Thus, the selected option reinforces an understanding of pediatric normotension based on age-specific calculations.
