6.2 Last-Week Review Map

6.2 Last-Week Review Map

The final week is for consolidation, not new material. Build the week around a high-yield integrated review of the facts the CPN tests most often, then drill them under timing. Start with your weakest high-weight blueprint domain (Assessment, Health Promotion, Management/Planning of Care, or Professional Role/Responsibilities), then move to mixed sets so you practice switching domains the way the real exam forces you to.

Vital-sign norms by age (memorize the trend)

The pattern is the exam answer: heart rate and respiratory rate fall with age; blood pressure rises with age. Tachypnea or tachycardia in an infant can be the earliest sign of distress before blood pressure drops, because children compensate well until they crash.

Exam trap: a respiratory rate of 50 is normal for a newborn but a red flag for a 10-year-old. Always index the number to the age in the stem.

Immunization schedule highlights

The most-tested vaccine facts cluster at predictable ages. Live vaccines (MMR, varicella) are not given before 12 months and are contraindicated in significant immunosuppression and pregnancy. Mild illness without fever is not a reason to defer; a true egg allergy is no longer a contraindication to MMR.

Developmental milestones (high-yield anchors)

Dosing and nutrition anchors: 4-2-1 fluid rule (4/2/1 mL/kg/hr by weight tier); convert lb to kg by dividing by 2.2; whole cow's milk begins at 12 months (not before, due to renal solute load and GI bleeding/iron-deficiency risk); transition to reduced-fat milk at age 2. Most-tested conditions to refresh: bronchiolitis/RSV, asthma, croup vs. epiglottitis, otitis media, gastroenteritis/dehydration, febrile seizures, sickle cell crisis, type 1 diabetes/DKA, and isolation precautions.

A calm week structure

• Day 7-5: weakest high-weight domain + the tables above
• Day 4-3: mixed timed 50-item sets, tag misses by domain and cause
• Day 2: error-log rules, calculations, immunization and vitals tables
• Day 1: logistics, light table review, sleep — no new resources

Most-tested conditions: the one-line cram

For each high-yield condition, drill the single fact the CPN most likely tests rather than the whole disease. These are the recognition cues and priority actions that recur across stems.

• Bronchiolitis/RSV: infants under 2; supportive care, nasal suctioning, hydration, oxygen — not routine antibiotics. Apnea risk in young infants.
• Croup vs. epiglottitis: croup = barky cough, stridor, viral, treat with cool mist/racemic epi and steroids; epiglottitis = drooling, tripod, toxic — do not examine the throat, keep the child calm, prepare for airway.
• Asthma: a quiet chest after wheezing signals worsening obstruction, not improvement.
• Febrile seizures: common 6 months-5 years, usually benign; protect airway, do not restrain, time the seizure.
• Gastroenteritis/dehydration: assess by weight loss, mucous membranes, cap refill, urine output; oral rehydration first for mild-moderate.
• Sickle cell vaso-occlusive crisis: hydration, oxygen, and prompt analgesia (often opioids) — pain is real, treat it.
• Type 1 diabetes/DKA: priority is fluids then insulin; watch potassium during correction.
• Otitis media: common after URI; amoxicillin first-line when antibiotics indicated.

Pain assessment scales by age

Match the tool to the developmental stage — a frequent exam distractor is using a self-report scale on a preverbal child.

Calculation and safety quick refresh

Keep the math reflexes warm: kg = lb ÷ 2.2; weight-based dose = mg/kg × kg, always checked against the safe maximum; maintenance fluids by 4-2-1. Safety-priority frameworks the exam rewards: ABCs and assessment-before-intervention on "first/priority" items, family-centered care on cultural items, and age-appropriate teaching (toddlers: time-out ~1 minute per year of age; whole milk at 12 months; rear-facing car seat to at least age 2). End the week confident in the tables, not anxious about edge cases.
