The nursing instructor is conducting a class on the development of an infant. The instructor determines the class is successful when the students correctly illustrate which as the proximodistal development in an infant?

Walk for several steps, then learns to run.

Roll over, then learns to follow an object with the eyes.

Imitate speech-like sounds, then learns to speak a language.

Kick and wave the arms, then learns to grasp the foot and pull it to the mouth.

Answer and Explanation

The Correct Answer is D

Choice A reason: Walking then running is a gross motor sequence, not proximodistal, which progresses from central to peripheral control. Arm waving to foot grasping shows this pattern, making this incorrect, as it does not illustrate the infant’s proximodistal development in the instructor’s class.

Choice B reason: Rolling over precedes eye tracking, but proximodistal development involves motor control from trunk to extremities. Arm waving to foot grasping better illustrates this, making this incorrect, as it does not reflect the central-to-peripheral progression of infant motor development in the lesson.

Choice C reason: Imitating sounds to speaking is linguistic, not proximodistal, which focuses on motor control from core to limbs. Arm waving to foot grasping demonstrates this pattern, making this incorrect, as it does not represent the physical developmental sequence taught in the infant development class.

Choice D reason: Kicking and arm waving involve trunk and proximal muscles, while grasping the foot uses distal control, illustrating proximodistal development. Students choosing this show understanding, aligning with infant motor development principles, making it the correct example for a successful class on infant development.

Correct Answer is C

Explanation

Choice A reason: Interesting textures may intrigue older infants but can overwhelm new eaters, risking rejection. Bland foods are better tolerated initially, making this less suitable and incorrect compared to the nurse’s focus on foods infants accept best when introducing solids in the class.

Choice B reason: Well-heated foods risk burns and aren’t preferred by infants, who tolerate room-temperature or slightly warm foods. Bland flavors are more acceptable, making this incorrect, as it doesn’t address the taste preference infants respond to best when starting solid foods in the diet.

Choice C reason: Bland foods are gentle on infants’ sensitive palates, encouraging acceptance when introducing solids. This aligns with pediatric nutrition guidelines for transitioning diets, making it the correct factor for the nurse to highlight in teaching parents about starting solid foods for infants.

Choice D reason: Thickened foods may pose choking risks or be hard to swallow for new eaters. Bland foods are more readily accepted, making this incorrect, as it doesn’t prioritize the flavor profile infants respond to best when introducing solid foods in the parent education class.

A. The enzymes secreted by the child’s liver and pancreas are much greater in amount than in the adult. B. The speed with which food passes through the gastrointestinal tract in the child is much slower than in the adult. C. The child’s gastrointestinal system is fully matured when the child is born. D. The child cannot break down and use complex carbohydrates in the same way the adult can.

Correct Answer is D

Explanation

Choice A reason: Children’s liver and pancreatic enzyme levels are not greater than adults’ but are sufficient for age-specific needs. Complex carbohydrate digestion is limited in children due to immature enzymes, making this inaccurate and incorrect compared to the carbohydrate metabolism difference in pediatric gastroenterology.

Choice B reason: Food passes through a child’s gastrointestinal tract faster, not slower, due to shorter intestines and higher motility. Limited complex carbohydrate digestion is the key difference, making this incorrect, as it misrepresents the speed of pediatric gastrointestinal transit compared to adults.

Choice C reason: The child’s gastrointestinal system is not fully mature at birth; it develops over years, particularly in enzyme function. Inability to digest complex carbohydrates reflects this immaturity, making this incorrect compared to the accurate statement about carbohydrate metabolism limitations in children.

Choice D reason: Children have limited ability to break down complex carbohydrates due to immature digestive enzymes, like amylase, compared to adults. This aligns with pediatric gastroenterology evidence, making it the most correct statement about the child’s gastrointestinal system development and function in digestion.
