Chapter 03: Developmental and Genetic Influences on Child Health Promotion Hockenberry: Wong’s Essentials of Pediatric Nursing, 10th Edition

1. An infant gains head control before sitting unassisted. The nurse recognizes that this is which type of development? a. Cephalocaudal b. Proximodistal c. Mass to specific d. Sequential ANS: A The pattern of development that is head-to-tail, or cephalocaudal, direction is described by an infant’s ability to gain head control before sitting unassisted. 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 another 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 specific 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. DIF: Cognitiv
