1. Normal in infants; abnormal after age 2.
2. Persistence beyond 1-2 years indicates neurologic disorder.
3. Extensor plantar response.
7: chadwicks sign
Correct Answer: Cervix is purple/blue (hyperemia from increased blood flow).

3. Breastfeeding: 10-15 minutes per side.
10: what is the placental hormone
Correct Answer: Human placental lactogen (hPL).
1. hPL modifies maternal metabolism to support fetal growth.
2. Acts as growth hormone, causes insulin resistance.
3. Also human chorionic gonadotropin (hCG) is placental hormone.
11: growth refers to
Correct Answer: Physical size (measurable changes in height, weight, head circumference).
1. Quantitative change.
2. Measured with growth charts.
3. Reflects nutritional status, health.
, 12: development refers to
Correct Answer: Chronological process (maturation of skills and abilities).
1. Qualitative change.
2. Follows predictable sequences (cephalocaudal, proximodistal).
3. Milestones assessed at each well-child visit.
13: atraumatic care
Correct Answer: Therapeutic delivery of care for children and families, prevents physical stressors and
separation of families, promotes sense of control.
1. Minimize fear, pain, separation.
2. Family-centered care model.
3. Use distraction, child life specialists.

Correct Answer: 7.5 lbs (3400g), 20 inches (50 cm).
1. Birth weight doubles by 6 months, triples by 1 year.
2. Length increases by 50% at 1 year.
3. Head circumference growth reflects brain growth.
15: CDC growth charts important facts
Correct Answer: Only Americans, does not include very low birth weights.
1. WHO growth charts are international standard.
2. CDC charts for children 2-20 years.
3. Special charts for preterm infants, specific conditions.
16: uterus is a
Correct Answer: Muscle (hollow, pear-shaped organ).
1. Myometrium is muscular layer for contractions.
2. Increases size dramatically during pregnancy.
3. Size of small pear pre-pregnancy larger than grapefruit at term.
