Chapter 32: developmental influences Flashcards
- What is the term for head-to-tail direction of growth?
a. Cephalocaudal
b. Proximodistal
c. Mass to specific
d. Sequential
ANS: A
The first pattern of development is in the head-to-tail, or cephalocaudal, direction. The head end of the organism develops first and is large and complex, whereas the lower end is smaller and simpler, and development takes place at a later time. Proximodistal, or near-to-far, is the second pattern of development. Limb buds develop before fingers and toes. Postnatally, the child has control of the shoulder before achieving mastery of the hands. Mass to specific is not a pattern of development. In all dimensions of growth, a definite, sequential pattern is followed.
- Which refers to those times in an individual’s life when he or she is more susceptible to positive or negative influences?
a. Sensitive period
b. Sequential period
c. Terminal points
d. Differentiation points
ANS: A
Sensitive periods are limited times during the process of growth when the organism will interact with a particular environment in a specific manner. These times make the organism more susceptible to positive or negative influences. The sequential period, terminal points, and differentiation points are developmental times that do not make the organism more susceptible to environmental interaction.
- If an infant weighed 3 kg at birth, how much would he or she be expected to weigh at age 1 year?
a. 6
b. 9
c. 12
d. 15
ANS: B
In general, birth weight triples by the end of the first year of life. For an infant who was 3 kg at birth, 9 kg would be the anticipated weight at the first birthday. A weight of 6 kg is below what one would anticipate, and weights of 12 and 15 kg are above what would be expected for an infant with a birth weight of 3 kg.
- How does the onset of the pubertal growth spurt compare in girls and boys?
a. It occurs earlier in boys.
b. It occurs earlier in girls.
c. It is about the same in both boys and girls.
d. In both boys and girls it depends on their growth in infancy.
ANS: B
Girls seem to be more advanced in physiological growth at all ages than boys. There does not appear to be a relation to growth during infancy.
- How is a child’s skeletal age best determined?
a. Assessment of dentition
b. Assessment of height over time
c. Facial bone development
d. Radiographs of the hand and wrist
ANS: D
The most accurate measure of skeletal age is radiological examinations of the growth plates. These are the epiphyseal cartilage plates. Radiographs of the hand and wrist provide the most useful screening to determine skeletal age. Age of tooth eruption varies considerably in children, so it would not be a good determinant of skeletal age. Assessment of height over time will provide a record of the child’s height, not skeletal age. Facial bone development does not reflect the child’s skeletal age, which is determined by radiographic assessment.
- Trauma to which site can result in a growth problem for children’s long bones?
a. Matrix
b. Connective tissue
c. Calcified cartilage
d. Epiphyseal cartilage plate
ANS: D
This is the area of active growth. Bone injury at the epiphyseal plate can significantly affect subsequent growth and development. Trauma or infection can result in deformity. The matrix, connective tissue, and calcified cartilage are not areas of active growth. Trauma at these sites will not result in growth problems for the long bones.
- Which is true about lymphoid tissues such as lymph nodes?
a. They reach adult size by age 1 year.
b. They reach adult size by age 13.
c. They reach half their adult size by age 5.
d. They are twice their adult size by age 10 to 12.
ANS: D
Lymph nodes grow rapidly and reach adult size at approximately age 6 years. They continue growing until they reach maximal development at age 10 to 12 years, which is twice their adult size. A rapid decline in lymph node size occurs until they reach adult size by the end of adolescence.
- Which is true about the basal metabolic rate (BMR) in children?
a. It is reduced by fever.
b. It is slightly higher in boys than it is in girls at all ages.
c. It increases with the age of the child.
d. It decreases as the proportion of surface area to body mass increases.
ANS: B
The BMR is the rate of metabolism when the body is at rest. At all ages, the rate is slightly higher in boys than it is in girls. The rate is increased by fever. The BMR is highest in infancy and then is closely related to the proportion of surface area to body mass. As the child grows, the proportion decreases progressively to maturity.
- A mother reports that her 6-year-old child is highly active and irritable. She has irregular habits and adapts slowly to new routines, people, or situations. According to Chess and Thomas, which temperament category best describes this child?
a. Easy child
b. Difficult child
c. Slow-to-warm-up child
d. Fast-to-warm-up child
ANS: B
This is a description of a difficult child, who compose about 10% of the population. Negative withdrawal responses are typical of this type of child, who requires a more structured environment. Mood expressions are usually intense and primarily negative. These children exhibit frequent periods of crying and often violent tantrums. Easy children are even-tempered, regular, and predictable in their habits. They are open and adaptable to change. Approximately 40% of children fit this description. Slow-to-warm-up children typically react negatively and with mild intensity to new stimuli and adapt slowly with repeated contact. Approximately 10% of children fit this description. Fast-to-warm-up children is not one of the categories identified by Chess and Thomas.
- By the time children reach their twelfth birthday, which should they have developed a sense of according to Erikson?
a. Identity
b. Industry
c. Integrity
d. Intimacy
ANS: B
Industry is the developmental task of school-age children. By age 12 years children engage in tasks that they can carry through to completion. They learn to compete and cooperate with others, and they learn rules. Identity versus role confusion is the developmental task of adolescence. Integrity and intimacy are not developmental tasks of childhood.
- The predominant characteristic of the intellectual development for children ages 2 to 7 years is egocentrism. What best describes this concept?
a. Selfishness
b. Self-centredness
c. A preference for playing alone
d. Inability to put oneself in another’s place
ANS: D
According to Piaget, a child this age is in the preoperational stage of development. Children interpret objects and events not in terms of their general properties but in terms of their own relationships to them. This egocentrism does not allow children in this age group to put themselves in another’s place. Selfishness, self-centredness, and preferring to play alone do not describe the concept of egocentricity.
- The nurse is observing parents playing with their 10-month-old daughter. What should the nurse recognize as evidence that the child is developing object permanence?
a. The child looks for the toy parents hide under the blanket.
b. The child returns the blocks to the same spot on the table.
c. The child recognizes that a ball of clay is the same when flattened out.
d. The child bangs two cubes held in her hands.
ANS: A
Object permanence is the realization that items that leave the visual field still exist. When the infant searches for the toy under the blanket, it is an indication that she has developed a sense of object permanence. Returning blocks to the same spot on a table is not an example of object permanence. Recognizing a ball of clay is the same when flat is an example of conservation, which occurs during the concrete operations stage from 7 to 11 years of age. Banging cubes together is a simple repetitive activity characteristic of developing a sense of cause and effect
- Which is a characteristic of the preoperational stage of cognitive development?
a. Thinking is logical.
b. Thinking is concrete.
c. Reasoning is inductive.
d. Generalizations can be made.
ANS: B
Preoperational thinking is concrete and tangible. Children in this stage of development cannot reason beyond the observable, and they lack the ability to make deductions or generalizations. Increasingly logical thought, inductive reasoning, and the ability to make generalizations are characteristic of the concrete operations stage of development that takes place from 7 to 11 years of age.
- Which behaviour is most characteristic of the concrete operations stage in cognitive development?
a. Progression from reflex activity to imitative behaviour
b. Inability to put oneself in another’s place
c. Increasingly logical and coherent thought processes
d. Ability to think in abstract terms and draw logical conclusions
ANS: C
During the concrete operations stage of development, which occurs approximately between the ages of 7 and 11 years, increasingly logical and coherent thought processes occur. This is characterized by the child’s ability to classify, sort, order, and organize facts to use in problem-solving. The progression from reflex activity to imitative behaviour is characteristic of the sensorimotor stage of development. The inability to put oneself in another’s place is characteristic of the preoperational stage of development. The ability to think in abstract terms and draw logical conclusions is characteristic of the formal operations stage of development.
- According to Kohlberg, children develop moral reasoning as they mature. What characteristic is most descriptive of the preschooler’s stage of moral development?
a. Obeying the rules of correct behaviour is important.
b. Showing respect for authority is important behaviour.
c. Behaviour that pleases others is considered good.
d. Actions are determined good or bad in terms of their consequences.
ANS: D
Preschoolers are most likely to exhibit characteristics of Kohlberg’s preconventional level of moral development. During this stage they are culturally oriented to labels of good or bad, right or wrong. Children integrate these concepts based on the physical or pleasurable consequences of their actions. Obeying rules of correct behaviour, showing respect for authority, and knowing behaviour that pleases others are characteristic of Kohlberg’s conventional level of moral development.
