Topic Card

Pediatric Dehydration - "Small body, fast fluid loss"

Children, especially infants, can lose fluid quickly and crash faster than adults.

What the NCLEX Wants You to Know

  • Priority: urine output, behavior, mucous membranes, and perfusion.
  • Common trap: assuming crying means hydration is okay. Tearless crying can be dehydration.

Causes

  • Vomiting
  • Diarrhea
  • Fever
  • Poor feeding
  • Burns
  • Hot environment

Signs & Symptoms by Body System

  • Behavior: sleepy, irritable, weak cry
  • Fluid clues: dry mouth, no tears, sunken fontanel in infant
  • Perfusion: fast pulse, cool skin, delayed cap refill, fewer wet diapers

Lab Value + Danger Zone

Watch electrolytes and urine concentration. Danger zone: no wet diaper for 8 hours, lethargy, or poor perfusion.

Nursing Actions - In Priority Order

  1. Assess airway/breathing if ill-appearing
  2. Check weight, I&O, mucous membranes, cap refill
  3. Report lethargy or low urine
  4. Give oral rehydration or IV fluids as ordered
  5. Teach small frequent sips

Patient Teaching

  • Count wet diapers.
  • Use oral rehydration solution as directed.
  • Seek help for lethargy or no urine.

Memory Trick

WET = Wet diapers, Energy, Tears.

NCLEX-Style Challenge

An infant with diarrhea has no wet diaper for 8 hours. What is the priority?

Answer: Assess hydration/perfusion and report promptly; prepare ordered rehydration.

Compare

How to compare this topic: Ask what is high vs low, expected vs dangerous, stable vs unstable, and PN task vs RN/provider task.
