A nurse is caring for a group of clients on a pediatric unit.Which of the following clients is most at risk for insufficient vascular perfusion?

The correct answer is D. A school-age child who is in a spica cast.Choice A rationaleAn adolescent with a urinary tract infection (UTI) is not at high risk for insufficient vascular perfusion. UTIs primarily affect the urinary system and do not typically impact vascular perfusion.Choice B rationaleA toddler receiving intravenous fluids is not at high risk for insufficient vascular perfusion. IV fluids help maintain hydration and vascular volume, supporting adequate perfusion.Choice C rationaleA preschooler with otitis media (ear infection) is not at high risk for insufficient vascular perfusion. Otitis media affects the middle ear and does not typically impact vascular perfusion.Choice D rationaleA school-age child in a spica cast is at high risk for insufficient vascular perfusion. The cast can restrict blood flow, leading to complications such as compartment syndrome, which requires immediate medical attention.
