Maternal & Child Health Nursing: Pediatric Nursing and Developmental Milestones

Comprehensive vocabulary flashcards covering neonatal assessments, pediatric physical and cognitive growth, and developmental milestones from the Maternal & Child Health Nursing course notes.

APGAR Score

A standardized scoring method developed by Dr. Virginia Apgar in $1952$ used to report the clinical status of a newborn infant immediately after birth and assess the need for resuscitation; evaluated at $1\,\text{minute}$ and $5\,\text{minutes}$ after birth across five categories scored $0$, $1$, or $2$ points each.

Silverman-Andersen Retraction Scoring

An assessment tool that evaluates neonatal respiratory distress based on five clinical signs (upper chest movement, lower chest retractions, xiphoid retractions, nares dilation, and expiratory grunt), where a score of $0-3$ indicates mild distress, $4-6$ indicates moderate distress, $> 6$ indicates impending respiratory failure, and $10$ indicates severe respiratory distress.

Post-term Infant

A newborn born after the $41^{\text{st}}\,\text{week}$ of pregnancy; these infants often present with dry, cracked, leatherlike skin, an absence of vernix, decreased or meconium-stained amniotic fluid, long fingernails, polycythemia, and hypoglycemia.

Preterm Infant

A live-born neonate delivered before the completion of the $37^{\text{th}}\,\text{week}$ of gestation, traditionally characterized by a birth weight of less than $2{,}500\,\text{g}$.

Newborn Screening (NBS)

The procedure of collecting blood drops from a newborn's heel onto a specialized collection card, typically between $24\,\text{and}\,48\,\text{hours}$ after birth, to perform biochemical testing for detectable heritable conditions.

Congenital Hypothyroidism

An endocrine disorder marked by insufficient production of thyroid hormones in a newborn, which can lead to intellectual disability and stunted physical growth if not identified and treated early.

Phenylketonuria (PKU)

An inherited inborn error of metabolism where the child lacks the ability to metabolize the amino acid phenylalanine, resulting in toxic accumulation that can cause irreversible brain damage.

Congenital Adrenal Hyperplasia (CAH)

A group of inherited disorders of the adrenal glands caused by a deficiency in an enzyme necessary to produce vital hormones, placing the infant at risk of a life-threatening adrenal crisis.

Glucose-6-Phosphate Dehydrogenase (G6PD) Deficiency

An inherited enzymatic deficiency involving red blood cells that can cause acute hemolytic anemia when babies are exposed to certain stressors or substances.

Galactosemia

An inborn error of metabolism marked by the inability to convert galactose into glucose, which can lead to severe organ damage or death if breast milk or lactose-containing feedings are not withheld.

Maple Syrup Urine Disease (MSUD)

An inherited defect in amino acid metabolism causing an inability to process specific dietary proteins, leading to ketoacidosis, a characteristic sweet maple odor in the urine, and fatal complications if untreated.

Small for Gestational Age (SGA)

A neonate whose birth weight is below the $10^{\text{th}}\,\text{percentile}$ on an intrauterine growth curve for that specific gestational age, typically caused by intrauterine growth restriction (IUGR).

Large for Gestational Age (LGA)

An infant whose birth weight plots above the $90^{\text{th}}\,\text{percentile}$ on an intrauterine growth chart for that gestational age (also termed macrosomia).

Thermoregulation

The physiological process of balancing heat production with heat loss to keep an infant's core body temperature within normal limits.

Brown Fat

A specialized, vascular adipose tissue found in mature newborns—principally concentrated in the intrascapular area, thorax, and perineum—that rapidly produces heat by increasing cellular metabolism.

Meconium

The newborn's initial stool passed within $24\,\text{hours}$ of birth; it is odorless, tar-like, sticky, and blackish-green, composed of swallowed amniotic fluid, mucus, lanugo, vernix, and intestinal secretions.

Transitional Stool

The loose, greenish stool passed on the $2^{\text{nd}}\,\text{or}\,3^{\text{rd}}\,\text{day}$ of life as the neonate transitions from passing meconium to digested milk stools.

Acrocyanosis

A benign, normal peripheral cyanosis causing bluish discoloration of the hands and feet in neonates during the initial $24\,\text{to}\,48\,\text{hours}$ following birth.

Harlequin Sign

A transient, harmless vasomotor event where an infant positioned on their side shows a sharp vertical midline demarcation with deep redness on the dependent side and blanching or pallor on the upper side.

Vernix Caseosa

A white, cheese-like lipoprotein substance covering the newborn's skin that functions as a protective lubricant and moisture barrier in utero.

Lanugo

Very fine, soft downy hair covering the shoulders, upper arms, forehead, ears, and back of a term infant, which normally sheds completely by $2\,\text{weeks}$ of life.

Mongolian Spots

Benign, slate-gray or bluish macular areas of hyperpigmentation typically found over the sacral or gluteal regions and extremities of newborns.

Milia

Tiny, pinpoint white sebaceous cysts resulting from unopened sebaceous glands, usually located across the bridge of the nose or cheeks of neonates, disappearing spontaneously within $3-4\,\text{weeks}$.

Erythema Toxicum

A benign, self-limiting neonatal rash with scattered papules and surrounding erythema (flea-bite rash) that emerges during the first $4\,\text{days}$ of life up to $2\,\text{weeks}$ of age.

Caput Succedaneum

Edematous swelling of the scalp occurring over the presenting part of the fetal head from pressure during labor; it crosses cranial suture lines and reabsorbs spontaneously within a few days.

Cephalohematoma

A subperiosteal collection of blood over a cranial bone resulting from the rupture of periosteal capillaries during birth; it is strictly limited by cranial suture lines and requires several weeks to resolve.

Craniotabes

Localized thinning and soft indentations of the cranial bones, typically induced by prolonged pressure of the fetal skull against the maternal pelvis in utero, which resolves without intervention over several months.

Nevus Flammeus

A flat, dark red or purplish vascular malformation (port-wine stain) caused by mature dilated capillaries, commonly presenting on the face or thighs, that does not blanch or fade with age.

Strawberry Hemangioma

An elevated, bright red cutaneous vascular tumor formed by immature capillaries that expands during infancy before progressively regressing by around $7\,\text{years}$ of age.

Anterior Fontanelle

The diamond-shaped junction (bregma) located between the frontal and parietal bones that normally ossifies and closes between $12\,\text{and}\,18\,\text{months}$ of age.

Posterior Fontanelle

The triangular membranous space (lambda) situated between the parietal and occipital bones of the infant cranium that closes between $2\,\text{and}\,3\,\text{months}$ of life.

Cryptorchidism

A condition in male infants where one or both testes fail to descend into the scrotal sac.

Witch's Milk

A thin, serous breast secretion produced by male or female neonates due to circulating maternal estrogen, resolving within approximately $1\,\text{week}$ as hormones clear.

Moro Reflex

An infantile primitive startle reflex where a sudden noise or loss of support prompts symmetrical extension and abduction of the arms and legs, followed by adduction into an embrace posture, fading by $4\,\text{to}\,5\,\text{months}$.

Rooting Reflex

A primitive reflex triggered by touching or stroking the cheek near the mouth, causing the neonate to turn their head toward the stimulus; disappears by around the $6^{\text{th}}\,\text{week}$ of life.

Extrusion Reflex

A protective oral motor reflex where an infant automatically thrusts their tongue outward when food or foreign substances touch the anterior tongue, fading around $4\,\text{months}$ of age.

Babinski Reflex

A neonatal neurological reflex elicited by stroking the outer edge of the sole upward in an inverted 'J' curve, which causes the toes to hyperextend and fan outward; normal until at least $3\,\text{months}$ of age.

Trunk Incurvation Reflex

A reflex tested in a prone infant by stroking downward along the paravertebral border, causing the infant to flex the trunk and swing their pelvis toward the touched side.

Negativism

A normal behavioral phase during the toddler years where children consistently say 'no' to assertions and commands as they establish independence and separate identity.

Genu Valgus

Electra Complex

A psychoanalytic developmental concept describing a preschool girl's emotional attachment and attraction toward her father.

Bruxism

Involuntary grinding or clenching of the teeth, which can manifest in preschool-age children as an outlet for tension or stress.

Decentering

Secondary Stuttering

A language disfluency involving repetition and prolongation of syllables or words that emerges during early childhood after fluent speech had previously been established.

Malocclusion

An abnormal dental alignment where the upper and lower teeth fail to meet properly, arising from genetic variations, premature tooth loss, or habits like thumb-sucking.

Hazing

A structured form of bullying involving humiliating, demeaning, or dangerous initiation rituals that prospective members are forced to perform to join clubs, teams, or organizations.

Pharming

The illicit adolescent practice of misusing prescription and over-the-counter medications taken from home medicine cabinets, often resulting in accidental toxic overdoses.
