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.
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 A
Explanation
Choice A reason: Milk is not a perfect food, as excessive intake in babies can displace iron-rich foods, causing iron-deficiency anemia. This misconception overlooks milk’s low iron content, making it the correct choice for a false statement compared to accurate causes discussed among nurses.
Choice B reason: Children struggle to get enough iron in early years due to rapid growth and limited dietary sources, a true statement. Milk as a perfect food is the misconception, making this correct and incorrect for identifying a false belief about iron-deficiency anemia in children.
Choice C reason: Economic problems contribute to malnutrition, including iron deficiency, by limiting access to nutritious foods, a valid point. The milk misconception directly misleads about dietary causes, making this accurate and incorrect compared to the false statement about milk’s role in anemia prevention.
Choice D reason: Caregivers’ lack of nutrition knowledge can lead to inadequate iron intake, a true cause of anemia. The milk statement is the misconception, as it wrongly promotes milk over iron sources, making this correct and incorrect for identifying the false belief in the discussion.
Correct Answer is C
Explanation
Choice A reason: Fever and stuffy nose are not reliable indicators of teething and may signal illness. Genetic variation explains delayed eruption in an 8-month-old, making this misleading and incorrect for addressing the mother’s anxiety about her baby’s lack of teeth in the phone consultation.
Choice B reason: Requiring x-rays if no teeth erupt by 9 months is premature, as teeth can appear up to 12 months normally. Genetic factors reassure without unnecessary tests, making this alarmist and incorrect for responding to the mother’s dentition concerns about her 8-month-old baby.
Choice C reason: Tooth eruption varies genetically, with some babies teething later (up to 12 months) without issue. This explanation reassures the mother about her 8-month-old’s delayed dentition, aligning with pediatric dental norms, making it the correct information to alleviate her anxiety effectively.
Choice D reason: Stating teeth should erupt by 8-10 months is inaccurate, as normal eruption can occur up to 12 months. Genetic variability better addresses the mother’s concern, making this incorrect, as it risks heightening anxiety with a rigid timeline for the baby’s tooth eruption.
