Procedural consent, preparation and child-life support — branching viva
Branching viva on procedural consent, preparation and child-life support: the consent-permission-assent framework and the Appelbaum capacity domains, the structured preparation conversation by developmental age, the bedside comfort bundle (topical anaesthesia, oral sucrose as absolute volume, breastfeeding, comfort positioning and distraction), the fear-tension-pain cycle, the restraint-versus-comfort-position distinction, the doctrine of necessity, and the management of needle fear and vasovagal episodes.

Opening (warm-up)
Examiner: A four-year-old needs intravenous cannulation for antibiotics on the ward. The team plans to hold her down. Walk me through your approach. [1]
Candidate: Before any needle, I run a four-question bedside assessment — who decides, what the child understands, what her current state is, and whether this procedure is right for her now. For consent, I take parental permission from the person with parental responsibility and layer in developmentally appropriate assent from the four-year-old, using the AAP consent-permission-assent framework; I document the basis on which I am acting. For preparation, because she is a preschool child, I prepare 30 to 60 minutes before with play and a simple, honest, concrete sequence — I show the equipment on a doll, use short concrete words like squeeze and cold, never say it will not hurt, and offer a real choice only where one genuinely exists. I would not hold her down: that is restraint, not a comfort position, and for a non-emergency procedure the least-restrictive alternative is the right approach. [1] [3]
