The guide contains 200 questions in total, structured sequentially across
five distinct developmental modules spanning the entire human lifespan.
Module 1: Prenatal Development, Infancy, and
Toddlerhood (Questions 1–50)
Question 1
A researcher is studying the effects of a specific chemical agent on
embryonic development. The agent is introduced during the third week post-
,conception, precisely during gastrulation. Which of the following
developmental milestones will most likely be directly disrupted by this
timing?
A. Cleavage of the zygote into a blastocyst
B. Implantation of the blastocyst into the uterine wall
C. Differentiation of the three primary germ layers
D. Formation of the mature placental barrier
* Correct Answer: C
* Rationale: Gastrulation occurs during the third week of prenatal
development and is characterized by the migration and differentiation of
cells to form the three primary germ layers: ectoderm, mesoderm, and
endoderm. Cleavage and implantation occur earlier (weeks 1–2 during the
germinal period), and the placenta continues to mature well into the
embryonic and fetal periods.
Question 2
A newborn infant presents with low birth weight, microcephaly, a smooth
philtrum, a thin upper lip, and structural cardiac defects. The mother admits
to consuming substance X frequently during the first trimester. Based on
these distinct phenotypic features, substance X is most likely:
A. Nicotine
B. Alcohol
C. Cocaine
D. Methamphetamine
* Correct Answer: B
* Rationale: The clinical presentation describes the classic craniofacial
dysmorphology associated with Fetal Alcohol Spectrum Disorders (FASD),
including a smooth philtrum, thin vermilion border of the upper lip,
,microcephaly, and growth restrictions. Nicotine is strongly linked to low birth
weight and prematurity but not these specific facial dysmorphisms.
Question 3
During a routine clinical assessment of a 2-month-old infant, the nurse
practitioner drops a medical file onto the examination table unexpectedly.
The infant responds by symmetrically abducting and extending the arms,
opening the hands, and then drawing the arms back toward the midline in an
embracing motion. This response is an example of which primitive reflex?
A. Babinski reflex
B. Rooting reflex
C. Moro reflex
D. Tonic neck reflex
* Correct Answer: C
* Rationale: The Moro reflex, or startle reflex, occurs in response to a sudden
loss of support or a loud noise, causing the infant to abduct/extend the arms
and then adduct them in a guarding posture. It typically disappears by 4 to 6
months of age. The Babinski involves toe fanning, rooting involves turning
toward a perioral tactile stimulus, and tonic neck is the "fencing" posture.
Question 4
An infant who is 8 months old is observed during a play session. The infant
accidentally drops a rattle over the edge of the highchair. Instead of crying or
losing interest immediately, the infant leans forward and actively looks over
the edge to locate the fallen object. According to Jean Piaget’s cognitive-
developmental theory, this behavior signifies the emergence of:
A. Primary circular reactions
B. Mental combinations
C. Object permanence
D. Conservation of mass
, * Correct Answer: C
* Rationale: Object permanence is the understanding that objects continue to
exist even when they cannot be observed through sight, hearing, or touch.
According to Piaget, this begins to develop during the sensorimotor substage
4 (around 8–12 months). Circular reactions are repetitive body movements,
and conservation does not emerge until early/middle childhood.
Question 5
During Mary Ainsworth’s Strange Situation paradigm, a 12-month-old infant
exhibits severe distress when the mother exits the room. Upon the mother's
return, the infant approaches her demanding to be picked up but
simultaneously squirms, kicks, and pushes away angrily, refusing to be
comforted by her proximity. This behavior is characteristic of which
attachment style?
A. Secure attachment
B. Avoidant attachment
C. Resistant/Ambivalent attachment
D. Disorganized/Disoriented attachment
* Correct Answer: C
* Rationale: Insecure resistant/ambivalent attachment is characterized by
intense distress upon separation and a combination of proximity-seeking
behaviors mixed with angry, resistant rejection upon reunion. Secure infants
are easily comforted, avoidant infants ignore the parent, and disorganized
infants display confused, contradictory, or fearful behaviors.
Question 6
A pediatrician assesses a healthy 18-month-old child and notes that the
toddler can successfully stack a tower of four blocks, scribble spontaneously
with a crayon, and use a spoon with minimal spilling. These developmental
achievements fall primarily under which domain?
