Hypertension in children — branching viva

Branching viva from the school health check with an elevated blood pressure, through the confirmation rule and the ambulatory study, the primary-versus-secondary stratification, the target-organ screen and the lifestyle-versus-drug decision, to the child who arrives in the emergency department with hypertensive encephalopathy and demands controlled intravenous reduction.

Prompt

You are the paediatric registrar in the outpatient clinic and the emergency department. The examiner asks you to assess three children: an eight-year-old found to have an elevated blood pressure at a routine check; a six-year-old with stage 2 hypertension, proteinuria and a small scarred kidney on ultrasound; and a twelve-year-old who presents with headache, visual disturbance and a blood pressure of 170/110 mmHg. The examiner releases information in stages.

Stem 1 — Eight-year-old with an elevated blood pressure at a routine check (5 minutes)

An eight-year-old girl has a blood pressure of 118/76 mmHg at her eight-year check, between the 90th and 95th percentile for her age, sex and height. The practice nurse asks you what to do. ^[1]

Branch A (examiner): How do you classify this reading, and what is the confirmation rule before you label her hypertensive? ^[1]

Branch B (examiner): What role does ambulatory blood pressure monitoring play here, and how does it distinguish white-coat from masked hypertension? ^[5] ^[3]

Branch C (examiner): If her three repeat readings and her ambulatory study are normal, what lifestyle advice still applies, and how often would you re-screen her? ^[7]
