Pediatric nursing is the care of children from infancy to adolescence. The specialty's founding claim — that children are not small adults — is so familiar it has stopped being heard, which is unfortunate, because it is literally true and is the reason the specialty exists.
What actually differs
Dosing. Almost everything is calculated per kilogram, against a weight that changes, in patients whose margin for error is small. Weight-based dosing is the single largest source of medication error risk in pediatrics, which is why independent double checks, standardized concentrations, and dosing limits are more pervasive here than anywhere except oncology.
Physiology. Children compensate for illness efficiently and then decompensate abruptly. A child with a normal blood pressure may be in profound shock; the falling blood pressure is a late finding, not an early one. Recognizing the earlier signs — tachycardia, capillary refill, mental status, work of breathing — is the specialty's core assessment skill.
Development. A two-year-old, a seven-year-old, and a fifteen-year-old with the same diagnosis need completely different explanations, preparation, and consent processes. Assessment depends on knowing what is normal for the age.
Consent and autonomy. Parents consent for young children; adolescents have a growing legal voice, and confidentiality rules for adolescent care around sexual health, substance use, and mental health vary by state and put the nurse between a teenager and a parent regularly.
The family is part of the unit of care. Parents stay, participate, and are frequently the source of the most important assessment information — a parent saying this is not how my child usually behaves outranks most vital signs.
Where the work happens
Children's hospitals and pediatric units; pediatric intensive care; pediatric emergency care; pediatric oncology and haematology; pediatric surgery and perioperative care; children with medical complexity and technology dependence, in hospital and at home; primary care and specialty clinics; schools; and pediatric home health and hospice.
Two nearby fields are separate specialties: newborn intensive care, and school nursing. See neonatal nursing and school nursing.
The demographics of pediatric inpatient care have shifted. Straightforward childhood illness is increasingly managed at home or in ambulatory settings, so the children who are admitted are disproportionately those with chronic and complex conditions — technology-dependent children, survivors of prematurity and of childhood cancer, and children with severe neurological impairment.
Certification
The Pediatric Nursing Certification Board is the specialty's principal certifying body.
CPN — certified pediatric nurse, the registered nurse credential. Eligibility requires either 1,800 hours in a pediatric nursing specialty within the past 24 months, or five years as a registered nurse in pediatric nursing with 3,000 pediatric hours in the last five years including 1,000 in the past 24 months.
CPNP-PC and CPNP-AC — pediatric nurse practitioners in primary and acute care, each requiring at least 500 supervised direct clinical hours in the relevant setting during the graduate programme.
PMHS — a mental health credential for pediatric and family nurse practitioners and pediatric clinical nurse specialists who provide mental health care to children and adolescents.
Emergency and oncology have their own pediatric credentials from their respective boards. See emergency nursing and oncology nursing.
Adolescent mental health
The single largest change in pediatric nursing over the past decade has been the volume of children presenting in mental health crisis. Emergency departments and pediatric units board adolescents waiting for psychiatric beds that do not exist, in rooms not designed for it, staffed by nurses whose training is medical. It is now a routine part of general pediatric nursing rather than a psychiatric subspecialty. See psychiatric-mental health nursing.
What the work costs
Pediatric nurses report high satisfaction and a specific kind of difficulty. Children who are seriously ill or dying, families in crisis, suspected abuse and the mandatory reporting that follows, and long relationships with chronically ill children who eventually die — these accumulate. See nurse burnout and nursing ethics.
California's regulation sets one licensed nurse to four patients or fewer on pediatric units.
