Explanation

In children aged 1-13 years, hypertension is defined as a blood pressure (BP) at or above the 95th percentile for their age, sex, and height.
For a 6-year-old child, the 95th percentile for systolic BP is approximately 108-109 mmHg and for diastolic BP is 69-70 mmHg.
A BP of 120/80 mmHg is significantly above this 95th percentile threshold.
Specifically, 120/80 mmHg meets the criteria for Stage 2 Hypertension, which is defined as a BP reading ≥95th percentile + 12 mmHg.

Option A: While a systolic pressure of 112 mmHg is above the 95th percentile (~108 mmHg) and thus qualifies as Stage 1 Hypertension, 120/80 mmHg represents a more severe and definitive case of hypertension (Stage 2). In 'best answer' questions, the most pronounced example is often correct.
Option B: A blood pressure of 90/60 mmHg is below the 90th percentile for a 6-year-old, which is considered a normal reading.
Option C: A blood pressure of 110/58 mmHg is generally considered 'Elevated Blood Pressure' (prehypertension) for a 6-year-old, as it falls between the 90th and 95th percentiles. It indicates a need for monitoring but is not yet classified as hypertension.

Clinical Relevance

Nursing practice connection: Use the key finding related to Pediatric Hypertension to guide bedside assessment, documentation, and the next nursing action.
Accurate BP measurement in children is crucial and requires using a cuff with a bladder width that is 40% of the arm circumference and a length that covers 80-100%.
A diagnosis of hypertension in a child requires elevated readings on at least three separate occasions to rule out transient elevations due to stress or activity (white coat hypertension).
Unlike in adults, where primary (essential) hypertension is common, hypertension in young children (especially severe cases) often points to an underlying secondary cause, such as kidney disease, coarctation of the aorta, or an endocrine disorder, which requires thorough investigation.

How to Approach the Question

First, identify the key information in the question: the patient is a 6-year-old child, and the question is about identifying a hypertensive blood pressure.
Recall that blood pressure standards for children are different from adults and are based on age, sex, and height percentiles.
Remember the general definition of pediatric hypertension: a blood pressure reading at or above the 95th percentile for that child.
Mentally estimate or recall the approximate normal and hypertensive values for a school-aged child. A normal systolic BP is around 100-105 mmHg.
Evaluate each option against this knowledge. 90/60 is normal. 110/58 and 112/60 are borderline or mildly elevated. 120/80 is significantly higher than the expected normal range.
Select the option that most clearly and definitively represents hypertension for this age group, which is 120/80 mmHg, corresponding to Stage 2 hypertension.
