In a child with a ventriculoperitoneal shunt, which vital-sign combination is most concerning for shunt obstruction and increased intracranial pressure?

In a child with a ventriculoperitoneal shunt, which vital-sign combination is most concerning for shunt obstruction and increased intracranial pressure?

• A. Blood pressure 120/72 mm Hg; pulse 76; respirations 18
• B. Blood pressure 140/92 mm Hg; pulse 58; respirations 8
• C. Blood pressure 110/70 mm Hg; pulse 90; respirations 16
• D. Blood pressure 90/60 mm Hg; pulse 120; respirations 20

Answer: (B)

Recognizing signs of increased intracranial pressure from a shunt problem hinges on the Cushing response. When ICP rises, the body often elevates the systolic blood pressure to sustain cerebral perfusion, while the heart rate slows and breathing becomes slow and shallow due to brainstem effects. This combination—high systolic BP, slow pulse, and reduced respirations—is a red flag for serious ICP elevation from shunt obstruction. The vitals with a systolic around 140 and diastolic 92, a pulse of 58, and respirations of 8 match this pattern, making it the most concerning finding. It signals imminent brain injury risk and requires urgent evaluation and management. Other patterns here are more compatible with normal physiology or different processes and do not indicate the same level of ICP concern.
