Parents of a 6-month-old infant ask the nurse why it is necessary to offer iron-rich formula to their child.
What is the correct response?
"The infant has ineffective digestive enzymes.”.
"The infant has exhausted maternal iron stores.”.
"The infant has a limited ability to produce red blood cells.”.
"The infant has a need for iron to support dentition.”. .
The Correct Answer is B
Choice A rationale:
"The infant has ineffective digestive enzymes" (Choice A) is not the primary reason for offering iron-rich formula to a 6-month-old infant. While infants may have limited digestive enzymes, the primary reason for introducing iron-rich foods or formula at this age is related to their iron stores being depleted, not enzyme function.
Choice B rationale:
Choice B is the correct answer because at around 6 months of age, an infant's iron stores received from the mother during pregnancy start to deplete. Breast milk, which is often the sole source of nutrition for infants, may not provide sufficient iron to meet their growing needs. This is why it's important to introduce iron-rich foods or formula at this stage to ensure the infant continues to receive an adequate supply of this essential mineral.
Choice C rationale:
"The infant has a limited ability to produce red blood cells" (Choice C) is not the primary reason for introducing iron-rich formula. While iron is essential for red blood cell production, the primary concern at this stage is the depletion of iron stores from the mother.
Choice D rationale:
"The infant has a need for iron to support dentition" (Choice D) is not a valid explanation for introducing iron-rich formula to a 6-month-old infant. Iron is not primarily related to the development of teeth, and this statement does not address the key nutritional needs of the infant at this age.

Correct Answer is A
Explanation
Choice A rationale:
Setting the table with paper plates. A 5-year-old child is typically capable of performing simple tasks that contribute to household chores. Setting the table with paper plates is an age-appropriate task for a 5-year-old because it involves basic motor skills and helps teach them responsibility. Paper plates are safe and do not require handling sharp objects or potentially harmful substances.
Choice B rationale:
Scrubbing out the sink with cleanser. Scrubbing out the sink with cleanser is not an appropriate task for a 5-year-old child. It involves the use of potentially harmful cleaning products and may require them to handle sharp or abrasive objects. This task exceeds the developmental capabilities and safety considerations for a child of this age.
Choice C rationale:
Washing the dirty knives. Washing dirty knives is a task that involves handling sharp objects and potentially hazardous items. It is not an appropriate task for a 5-year-old child due to the safety risks involved. This task requires a level of fine motor skills and responsibility that is beyond what a child of this age can reasonably handle.
Choice D rationale:
Carrying glasses from the table to the sink. Carrying glasses from the table to the sink is a task that can be appropriate for a 5-year-old child. It does not involve handling sharp objects or dangerous chemicals, and it contributes to basic household chores. However, supervision is essential to ensure the child's safety and prevent accidents. .
Correct Answer is A
Explanation
Choice A rationale:
The pincer grasp is the coordination of the index finger and thumb to pick up small objects. It is a developmental milestone that typically occurs around 9-12 months of age. This behavior indicates that the infant has developed the ability to use the pincer grasp to manipulate objects. It is an essential skill for fine motor development and is a positive sign of the child's motor skills progressing.
Choice B rationale:
Prehension ability refers to the general ability to grasp objects but does not specifically describe the pincer grasp. While the infant is displaying a form of prehension by picking up cereal, the pincer grasp is a more specific and advanced skill.
Choice C rationale:
A grasp reflex is an automatic and involuntary response to touch, and it is typically present in newborns but should disappear as the infant develops. The behavior described in the question is not a grasp reflex, as it involves a deliberate use of the index finger and thumb.
Choice D rationale:
The parachute reflex is a protective reflex that appears later in infancy and involves extending the arms when the infant feels like they are falling. It is not relevant to the described behavior of picking up cereal with the fingers.
