Clinical teaching and practical ideas for your next study session.
When a Teen Mentions Pain Pills: Build an Adult-Controlled Safety Plan
If a teen’s mention of pain pills raises concern for suicide, a vague promise to lock up medications is not enough. Learn to build and verify a caregiver-led plan that makes medicines inaccessible while keeping suicide-risk assessment in view.
How Oxygen Toxicity Disrupts Lung Development in Preterm Infants
Why can life-saving oxygen contribute to BPD? Follow the mechanism from reactive oxygen species to inflammatory injury, impaired alveolar septation, and altered pulmonary vascular growth—while keeping oxygen toxicity in its proper, multifactorial context.
Neonatal Oxygenation Index: Why PaO₂ Needs Ventilator Context
The same PaO₂ can reflect very different degrees of respiratory failure depending on FiO₂ and mean airway pressure. Learn how oxygenation index puts arterial oxygenation in support context—and why it cannot identify the cause.
Normal Initial Skeletal Survey: Why Repeat Imaging Matters
A negative first skeletal survey describes what was visible on that study—not necessarily every injury. Learn how timing, fracture type, and image quality shape the decision to repeat imaging.
Food Allergy and Asthma: Use the Risk Flag Without Overcalling It
Asthma is a classic risk flag in fatal food-anaphylaxis teaching, not an individual prediction. Learn what it changes after stabilization: asthma-control review, reaction recognition, and epinephrine readiness.
Pediatric Status Asthmaticus: Avoid Both Fluid Depletion and Overload
Fluid decisions in severe pediatric asthma are not a choice between routine boluses and automatic restriction. Separate resuscitation, deficit replacement, and maintenance—and do not mistake elevated ADH for SIADH.
Acyclovir Resistance in Children: Why Valacyclovir May Fail
Viral thymidine kinase activates acyclovir—and creates a resistance weak point. Learn why switching to valacyclovir may not help persistent pediatric HSV.
Persistent Fever After Pediatric UTI: When Acute Ultrasound Matters
Persistent fever during pediatric UTI treatment is a reassessment signal, not a diagnosis. Learn when acute renal-bladder ultrasound may uncover a complication—and how that differs from imaging after recovery.
Pediatric Hypoglycemia: What to Draw Before Dextrose—and What Can Wait
The critical-sample decision is about timing: which blood and urine tests are most useful while glucose is low, which can follow, and when treatment must come first.
Ketotic Hypoglycemia in Children: What High β-Hydroxybutyrate Can—and Can’t—Tell You
A high β-hydroxybutyrate level with suppressed insulin identifies a ketotic response to hypoglycemia, not its cause. Learn what the pattern supports, what it cannot rule out, and which parts of the child’s history change the next decision.
Why Pediatric Septic Arthritis Can Destroy Cartilage So Quickly
The key mechanism is a neutrophil-rich host response that drives protease-mediated cartilage damage. Follow the cascade to understand why prompt sampling, antibiotics, and source-control planning matter.
After an Abnormal Direct Bilirubin: Why a Normal Ultrasound Does Not Clear the Infant
At 2–4 weeks, a direct bilirubin ≥1 mg/dL is an urgent consultation signal, not a biliary-atresia diagnosis. Learn why stool color, GGT, bilirubin trends, and ultrasound refine the differential without safely ending the evaluation.
