Semester 3

๐ŸงธPediatrics

Tiny humans, enormous consequences, zero margin for error.

Peds is not 'small adult med-surg.' Kids compensate beautifully and then crash without warning. This semester is about developmental milestones, weight-based everything, and recognizing the quiet kid who is actually in trouble.

Real talk about this course

  • โ€ขMilestones will be tested to the month. Learn them in blocks, not individually.
  • โ€ขEvery dose is weight-based. Every single one. Safe-dose-range questions are guaranteed.
  • โ€ขRespiratory failure is the number one cause of pediatric arrest. Kids arrest from breathing, not hearts.
  • โ€ขThe parent's report matters. 'He's just not acting right' is clinical data.

Grade savers ๐Ÿ‘‘

  • A quiet, listless child is sicker than a screaming one.
  • Hypotension in a child is a LATE and pre-arrest sign.
  • Never palpate the abdomen of a child with suspected Wilms tumor.
  • Count a pediatric respiratory rate for a full minute, before you touch them.

Milestones in blocks

Trying to memorize month by month is a losing game. Anchor points work.

Memory trick

2 mo: social smile. 4 mo: rolls front to back. 6 mo: sits with support, first solids, stranger anxiety starts. 9 mo: crawls, pincer grasp emerging. 12 mo: walks, 1โ€“3 words, triples birth weight. 2 yr: 2-word phrases, runs, half of adult height. 3 yr: tricycle, 3-word sentences.

Age = number of words. Two years, two words. Three years, three words. You're welcome.

Respiratory distress vs failure in kids

The difference between 'watch closely' and 'call the code.'

Memory trick

Distress: retractions, nasal flaring, grunting, tachypnea, tripod position. Failure: bradycardia, decreased effort, silent chest, altered LOC, cyanosis. Grunting in an infant is an emergency sign โ€” it's their own PEEP.

A tired baby who stops working to breathe is not improving. Get help.

Dehydration assessment

Most common peds admission and most common exam topic.

Memory trick

Best indicators: weight loss, urine output (infant <1 mL/kg/hr is low), capillary refill, sunken fontanel, absence of tears, mucous membranes. Weight is the gold standard โ€” 1 kg lost = 1 L lost.

Immunization schedule anchors

They will ask which vaccine is due at which visit.

Memory trick

Birth: Hep B. 2/4/6 mo: DTaP, IPV, Hib, PCV, rotavirus. 12โ€“15 mo: MMR, varicella, Hep A. Live vaccines (MMR, varicella) are avoided in immunocompromised kids and pregnancy.

Classic peds conditions with tells

Peds exams are built around signature findings.

Memory trick

Barking seal cough + stridor = croup (humidity, racemic epi, steroids). Drooling + tripod + no cough = epiglottitis (do NOT inspect the throat, prep for airway). Currant jelly stool + sausage mass = intussusception. Olive mass + projectile vomiting in a 4-week-old = pyloric stenosis. Strawberry tongue + high fever โ‰ฅ5 days = Kawasaki (IVIG, aspirin โ€” the one time kids get aspirin).

Drooling child who won't lie down? Hands off that throat. Nothing in the mouth.

Safe dose range math

Free points once, lost points forever if you skip the practice.

Memory trick

Convert pounds to kg (รท2.2), multiply by the low and high mg/kg/day, divide by the number of doses, compare with what's ordered. If the ordered dose falls outside the range, you hold and clarify.

'It's close enough' is not a nursing intervention in peds.

Pain and communication by age

Assessment tools are testable and age-specific.

Memory trick

FLACC: infants/nonverbal. FACES (Wong-Baker): 3+ years. Numeric 0โ€“10: about 7โ€“8+ years. Toddlers fear separation; preschoolers fear body harm and think illness is punishment; school-age want control; teens fear loss of independence and peer identity.

Car seats and safety by stage

Anticipatory guidance is a guaranteed teaching question.

Memory trick

Rear-facing until at least age 2 (or max height/weight of the seat), back seat until age 13. Infants sleep alone, on their back, in a bare crib. No honey before 12 months (botulism). No whole cow's milk before 12 months.
