📚 Pediatric Fever Management — full study notes
The cheat sheet above is your quick recall card. These notes go deeper — what it is, what to do first, what must be reported, and what to teach.
Fever is a common, usually protective response to infection rather than a disease itself. Management focuses on the child's comfort and hydration, not on normalizing the number. Key principle: a fever in an infant under 3 months is a medical emergency requiring immediate evaluation, regardless of how well the baby appears.
🔑
Key points
Understand these first
Fever is generally a temperature of 100.4 F (38 C) or higher; the route used affects the reading.
Any fever in an infant under 3 months (rectal temp 100.4 F or higher) is a red flag requiring urgent medical evaluation.
Antipyretics are dosed by weight: acetaminophen every 4-6 hours and ibuprofen (only for children over 6 months) every 6-8 hours.
Aspirin is contraindicated in children due to the risk of Reye syndrome.
Febrile seizures are usually benign, brief, and self-limited, most common between 6 months and 5 years.
Fever increases fluid losses, so maintaining hydration is a priority.
✅
Nursing priorities
What to do, in order
Measure temperature with an age-appropriate, accurate method and document the route.
Administer weight-based antipyretics for comfort and reassess effect.
Encourage frequent fluids and monitor intake/output and hydration status.
Dress the child lightly and keep the room comfortable; avoid bundling.
Assess overall appearance, activity, and signs of serious infection rather than fixating on the number.
🚩
Red flags — report now
Escalate immediately
Fever in an infant under 3 months requires immediate evaluation for serious infection (sepsis, meningitis).
Never give aspirin to a child or teen with a febrile/viral illness (Reye syndrome risk).
Stiff neck, petechial or purpuric rash, lethargy, difficulty breathing, or a seizure lasting over 5 minutes is an emergency.
Do not sponge a child with cold water or alcohol; it causes shivering, vasoconstriction, and toxicity.

Labs & values
Numbers to know
WBC: 5,000-15,000/mm3 in children (elevated with bacterial infection)
Blood cultures and urinalysis for fever workup in young infants

Patient teaching
What patients must know
Use a weight-based dose with the device that comes with the medication; do not dose by age alone.
Offer fluids often and watch for dehydration: fewer wet diapers, dry mouth, no tears.
Do not alternate or double up antipyretics without provider guidance, and never use aspirin.
Seek care for a fever in a baby under 3 months, a fever over 5 days, or a child who appears very ill, difficult to wake, or has trouble breathing.
