CPedN(C) - Pediatric Nursing key terms

A measurable increase in body size or mass, such as weight, length, or head circumference, tracked over time on standardized charts to confirm a child is progressing as expected.

The progressive gain in physical, cognitive, language, and social skills that lets a child do more complex things over time. It is assessed by milestones rather than by size alone.

A skill most children can perform by a certain age, such as sitting unsupported or using two-word phrases. Nurses use them to detect delay early and to teach parents what to expect next.

A ranking that shows where a child's measurement falls compared with peers of the same age and sex. Clinicians watch the trend across visits more closely than any single plotted point.

Proactive teaching that prepares caregivers for the next stage of a child's growth, such as starting solids or childproofing. It is delivered at well visits before problems arise.

A scheduled preventive visit for a well child that combines physical examination, screening, immunizations, growth and development review, and caregiver education tailored to the child's age.

The recommended timing and sequence of vaccines for each age, including catch-up rules for children who are late. Nurses verify status at every encounter and document lot and site.

A sign or symptom that signals possible serious disease or delay and requires prompt escalation rather than routine follow-up, such as loss of previously gained milestones or persistent poor feeding.

An approach that treats the family as the child's constant partner in care, honoring their preferences, culture, and expertise while the health team provides information and support.

A working alliance in which the nurse shares information openly, negotiates goals with the family, and supports the caregiver's role in comforting and decision-making for the child.

Purposeful conversation using open questions, reflection, and age-appropriate language to help a child or caregiver express feelings and understand care. It avoids false reassurance and judgment.

Distress a young child shows when parted from a primary caregiver, peaking in toddlerhood and intensifying during hospitalization. Strategies include rooming-in and consistent caregivers.

A rapid first impression built from appearance, work of breathing, and circulation to the skin. It is completed in seconds before touching the child and guides urgency of the full assessment.

A numeric score calculated from vital signs and behavior that flags a hospitalized child whose condition may be deteriorating, prompting earlier review by the care team.

Normal ranges for heart rate, respiratory rate, and blood pressure that change with age, with infants normally breathing and beating faster than adolescents. Values must be judged against age norms.

A validated tool matched to the child's age and ability, such as a faces scale for preschoolers or a behavioral scale for infants, used to score and reassess pain after intervention.

Calculating a medication dose from the child's weight in kilograms, since pediatric doses are usually expressed per kilogram. Weight must be confirmed and the result checked against safe maximums.

The published minimum and maximum amount of a drug considered effective and tolerable for a given weight or age. Nurses verify the ordered dose falls inside it before giving.

A drug carrying heightened risk of serious harm when misused, such as insulin, opioids, or concentrated electrolytes. These require independent double-checks and standardized administration.

A structured comparison of all medicines a child actually takes, including over-the-counter and herbal products, against new orders at admission, transfer, and discharge to prevent errors.

Instruction that confirms a caregiver can measure, give, and store a child's medicine correctly, including timing, missed doses, side effects to report, and use of an oral syringe rather than a spoon.

Increased effort of breathing shown by retractions, nasal flaring, grunting, or tachypnea. It can progress to failure, so the nurse reassesses frequently and escalates early.

Use of pulse oximetry to estimate how much hemoglobin is carrying oxygen. Trends and the child's work of breathing matter more than a single reading in pediatric care.

Delivery of aerosolized medication, such as a bronchodilator, through a mask or mouthpiece into the lungs. Nurses monitor response, heart rate, and side effects during and after.

A structural abnormality of the heart or great vessels present at birth. Signs include poor feeding, cyanosis, and poor weight gain; care focuses on growth, oxygenation, and infection prevention.

A deficit of body water often caused by vomiting, diarrhea, or fever. Signs include dry mucous membranes, reduced urine output, and sunken eyes; severity guides oral or intravenous rehydration.

The amount of fluid a child needs daily to replace normal losses, commonly estimated by weight using a standard formula. It is adjusted for fever, illness, and ongoing losses.

Giving small, frequent amounts of an electrolyte solution by mouth or feeding tube to correct mild to moderate dehydration. It is preferred when the child can tolerate enteral intake.

Excess fluid in the body causing weight gain, edema, and breathing difficulty. Nurses weigh daily, monitor intake and output, and watch for crackles, especially in children with heart or kidney disease.

Inadequate weight gain or growth in a child that may stem from medical, feeding, or psychosocial causes. Care includes careful measurement, feeding assessment, and family support.

Age-specific safety teaching given to caregivers, such as car seat use, water supervision, safe sleep, and poison storage, delivered before the child is likely to attempt the hazard.

Placing infants on their back on a firm, flat surface with no loose bedding or soft objects to reduce suffocation and sudden infant death risk. Room-sharing without bed-sharing is advised.

Rapid sorting of patients by urgency so the sickest are treated first. Pediatric triage accounts for age-specific signs and for a child who may look well while deteriorating quickly.

Use of play, drawing, or medical props to help a child express fears, prepare for procedures, and regain a sense of control. It is matched to the child's developmental stage.

Confidential questioning of teens about mood, safety, substance use, and sexual health, conducted with the caregiver absent when appropriate, so honest answers and timely referral are possible.

Permission for treatment given by a parent or legal guardian after receiving risks, benefits, and alternatives, with the child's agreement sought at a developmentally appropriate level.

Protecting a teen's health information within legal limits, while explaining what will and will not be shared with caregivers so trust and safety are both maintained.

Verifying identity using two independent identifiers, such as name and date of birth, before giving medication or performing a procedure, and never relying on room or bed number.
