  1. Which fontanelle in a newborn typically closes last, around 18–24 months of age?

    Answer: Anterior fontanelle

    The anterior (front) fontanelle is the largest and closes last, usually between 18 and 24 months.

  2. A newborn's skin is covered at birth by a waxy protective coating called:

    Answer: Vernix caseosa

    Vernix caseosa is the white, cheese-like protective coating that covers the newborn's skin at birth.

  3. What is the normal resting heart rate range for a newborn (0–1 month)?

    Answer: 100–160 bpm

    Newborn heart rates normally range from 100 to 160 beats per minute.

  4. The primary structural difference between a child's trachea and an adult's trachea is that the child's trachea is:

    Answer: Shorter, narrower, and more flexible

    A child's trachea is shorter, narrower, and more pliable than an adult's, making positioning during massage critical.

  5. Which reflex, present at birth, causes an infant to turn its head toward a stimulus touching its cheek?

    Answer: Rooting reflex

    The rooting reflex helps infants locate the nipple for feeding by turning the head toward tactile stimulation on the cheek.

  6. In pediatric massage, why is a child's liver considered more vulnerable to pressure than an adult's?

    Answer: It extends lower below the rib cage and is proportionally larger

    A child's liver is proportionally larger and extends further below the costal margin, making it more susceptible to direct pressure.
