The nurse observes a 10-month-old infant using her index finger and thumb to pick up pieces of cereal.
What does this behavior indicate the infant has developed?
The pincer grasp.
Prehension ability.
A grasp reflex.
The parachute reflex.
The Correct Answer is A
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.

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 D
Explanation
The correct answer is Choice D: 4 times the birth weight.
Choice A rationale:
A toddler at this age is expected to have a weight gain that results in being about 4 times their birth weight, so 2.5 times is less than expected.
Choice B rationale:
While 3 times the birth weight indicates significant growth, it is still not the typical expected weight gain for a 3-year-old.
Choice C rationale:
Doubling the birth weight is expected within the first few months of life, not at 3 years old.
Choice D rationale:
By the age of 3, children are generally expected to weigh about four times their birth weight, reflecting normal growth and development.
