Pediatric Patient, Adult-Sized Effort: When to Stop
You are a physiotherapist covering a pediatric ward. A 7-year-old child (weight 22 kg) with a recent lower-limb fracture is referred for mobilization. The order reads 'mobilize as tolerated.' On standing, the child becomes pale, reports dizziness, and their heart rate rises from 96 to 148 bpm over about a minute; respiratory rate rises from 22 to 34, and they are clinging to your arm. The child's mother is anxious and says, 'The doctor said he must walk today or he'll get weak.' A colleague is available but is treating another child. You have a pulse oximeter and a chair within two steps.
1. What do you do in the next 60 seconds, and what findings drive your decision?

Stop and make the child safe.
- Seat the child immediately in the chair within reach and stay with them; do not continue to 'push through.'
- Assess: recheck HR, RR, SpO2, color, and level of responsiveness; ask about dizziness, chest pain, and how they feel. Pale skin plus dizziness plus a jump from 96 to 148 bpm and RR 22 to 34 in a 7-year-old is an abnormal exercise response, not normal effort.
- Consider causes: pain, fear/anxiety, dehydration, orthostatic intolerance, or a medical complication. The recent fracture and immobilization also raise the question of other causes the medical team should assess.
- Call for help if symptoms do not settle quickly with rest, or if SpO2 falls, the child becomes drowsy, or the tachycardia persists.
- Do not resume mobilization until the child is back to baseline and the medical team has been informed.
Justification: 'as tolerated' means the child's tolerance sets the limit. A heart rate near 150 with pallor and dizziness in a 7-year-old is a stop signal, and the safe default is to halt, assess, and escalate rather than to satisfy the parent's expectation.
2. The mother insists the child must walk today. How do you respond while maintaining the therapeutic relationship?

Acknowledge, explain, redirect.
- Acknowledge her concern: 'I understand you're worried about weakness - that's a real concern and we will keep working on it.'
- Explain in plain language: 'Right now his heart rate and breathing are much higher than they should be, and he's pale and dizzy. Pushing him now could make him faint or fall. We stop, let him recover, and tell the doctor.'
- Offer a plan, not a refusal: short, frequent, assisted transfers or seated exercises once he recovers, and a review of the order with the medical team.
- Involve the team: ask the treating doctor to speak with the mother about the plan and the reason for today's change.
- Document the conversation and the mother's concerns.
Why: the goal is not to win the argument but to keep the mother engaged with a safe plan. Explaining the physiological reason and giving a concrete next step is more effective than citing policy.
3. What do you document and report, and to whom?
Read the worked answer
Document:
- Baseline and event vitals (HR 96→148, RR 22→34), pallor, dizziness, and the time course.
- That mobilization was stopped, the child was seated, and the response to rest.
- The mother's request and the education given.
- The plan (hold mobilization, medical review, reassess).
Report to:
- The treating physician/medical team promptly - an abnormal response to mobilization in a child warrants assessment.
- The nurse in charge of the child.
- The child's record and, if the unit uses one, an incident/clinical deterioration note.
Why: the value of the case is in closing the loop - stopping is necessary but not sufficient; the medical team must know so they can determine whether the response reflects pain, anxiety, dehydration, or something more serious.
