Emergency & Airway Dynamics
While an adult's heart rate spikes when they're in severe trouble, a sick infant's heart rate dropping below 60 BPM with poor perfusion is so dangerous it requires starting this immediately.
What is CPR (or chest compressions)?
The normal resting heart rate range for a healthy infant is much higher than an adult's, typically ranging between these two numbers.
What is 120 to 160 beats per minute?
While a viral rash stays in one spot for days, these allergic welts are famous for rapidly changing shape and moving to different parts of the body within 24 hours.
What are hives (or urticaria)?
You should never give honey to a baby under 1 year old because their immature gut allows bacterial spores to grow and release a toxin that causes this "floppy" condition.
What is infant botulism?
Unless an exception applies, a person legally transforms into an autonomous adult instantly gaining the exclusive right to make their own medical decisions at this age milestone.
What is 18 years old (or the age of majority)?
Unlike adults who usually crash from a primary heart problem like a heart attack, pediatric cardiac arrest is almost always the end result of a failure in this system.
What is the respiratory system (or progressive respiratory failure / hypoxia)?
While an adult normally breathes 12 to 20 times per minute, a healthy newborn's normal baseline respiratory rate is much faster, sitting in this range.
What is 30 to 60 breaths per minute?
Thick, purulent, foul-smelling nasal discharge coming from only one nostril in a toddler is a major clue for this physical issue.
What is a nasal foreign body?
Toddlers who chug more than 24 ounces of cow's milk a day often develop pale skin and severe fatigue because milk fills them up and blocks the absorption of this vital mineral.
What is iron (causing "milk anemia")?
Healthcare professionals and teachers are legally classified as these, meaning they are required by law to report suspected child abuse directly to Child Protective Services
What are mandated reporters?
To deliver an EpiPen correctly during a severe anaphylactic reaction, the auto-injector must be pressed firmly into the anterolateral aspect of this specific muscle for a full 3 seconds.
What is the thigh (or vastus lateralis / outer thigh)?
When performing otoscopy on an infant or toddler under 3 years old, you pull the pinna (outer ear) in these two directions to straighten the ear canal.
What is down and back?
Despite having "worm" in its name, Ringworm is actually caused by this type of organism, meaning antibiotics will do absolutely nothing to treat it.
What is a fungus (or fungal infection)
Giving plain water to a baby under 6 months old is dangerous because their immature kidneys can't handle it, potentially causing seizures from this electrolyte drop.
What is hyponatremia (or low sodium)?
Parents give legal consent for a 10-year-old's surgery, but ethical practice requires getting the child's explicit agreement, which is known as this.
What is assent?
Statistically, this body structure is the most common cause of soft-tissue upper airway obstruction in an unconscious or sedated pediatric patient.
What is the tongue?
In a child experiencing severe fluid loss or shock, cool hands and feet combined with a capillary refill time taking longer than this specific duration indicates peripheral blood vessels are tightly constricted.
What is 2 seconds?
An active middle ear infection (Acute Otitis Media) usually features deep ear pain, fever, and this specific physical appearance of the tympanic membrane on otoscopy.
What is bulging (or a bulging eardrum)?
Bulimia nervosa patients who purge frequently are at risk for sudden, fatal heart rhythms because vomiting drains the body of this specific electrical electrolyte
What is potassium (hypokalemia)?
Under the Mature Minor Doctrine, older teenagers can often give their own legal consent for mental health, substance abuse, and this type of sensitive healthcare without parents.
What is reproductive health (or STIs / contraception)?
While adult asthmatics struggle primarily with bronchospasm, pediatric asthma is a complex lower airway triad that combines muscle constriction with these two additional pathophysiological processes.
What are airway inflammation and mucus hypersecretion (or mucus plugging)?
Because an infant's head accounts for up to 20% of their total body surface area and skin insulation is thin, infants rely heavily on metabolizing this specialized fat to generate heat.
What is brown fat?
Ear infections are way more common in toddlers than adults because their Eustachian tubes are much flatter, sitting at this near-horizontal angle.
What is 10 degrees?
Unlike Anorexia, this restrictive eating disorder causes severe food avoidance due to texture sensory issues or fear of choking, without any concern about body weight.
What is ARFID (Avoidant/Restrictive Food Intake Disorder)?
The "diagnostic triad" of Abusive Head Trauma consists of brain swelling, bleeding in the back of the eyes, and this type of bleeding beneath the skull.
What is a subdural hematoma?
