A 2-year-old boy is in the hospital outpatient department for observation after falling out of his crib and hitting his head. The nurse calls the…

A rectal temperature of 102°F (38.9°C) is a significant fever and a critical finding in a child being observed for a head injury. Hyperthermia following a traumatic brain injury (TBI) can indicate central nervous system involvement, such as hypothalamic dysregulation, or the onset of an infection. Importantly, fever increases the brain's metabolic rate, which can exacerbate secondary brain injury and worsen neurological outcomes. This change in condition warrants immediate notification of the physician for further assessment and intervention to manage the fever and investigate its cause.

A. Evidence of perineal irritation: This finding is unrelated to the primary diagnosis of a head injury and is not an urgent concern in this context.

B. Pulse fell from 102 to 96: This is a minor fluctuation within the normal resting pulse rate range for a 2-year-old (approximately 70-110 beats/min) and is not clinically alarming.

C. Pulse increased from 96 to 102: Similar to the decrease, this slight increase is well within the normal pulse rate range for a toddler and is not a significant finding.

In the chapter on pediatric neurologic dysfunction, the text emphasizes that hyperthermia is a common complication of cerebral insults and must be managed to prevent increased cerebral metabolism (Chapter 28, p. 839).

The guidelines state that "hyperthermia should be avoided and treated aggressively" in pediatric TBI patients, highlighting its significance in worsening outcomes (Section: Temperature Control, p.

This university-affiliated clinical care guideline specifies frequent monitoring of vital signs, including temperature, with parameters for physician notification. A temperature >38.5°C (101.3°F) is typically a trigger for intervention and notification, making 102°F a critical value to report (Section: Nursing Care, Monitoring).
