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:
Push-pull toys are suitable for a 3-year-old because they promote physical activity and coordination. These toys help children develop their motor skills and provide a fun way for them to engage with their environment. Push-pull toys are age-appropriate and safe for toddlers.
Choice B rationale:
A large construction set may have small parts that could be a choking hazard for a 3-year-old. It's essential to select toys that do not pose such risks and are developmentally appropriate. Therefore, this choice is not the most appropriate toy for a 3-year-old.
Choice C rationale:
A small pet, such as a goldfish, is not an appropriate toy for a 3-year-old. Pets are living creatures that require care and attention. Introducing a pet to a young child should be a well-considered decision made by the family and not seen as a toy choice.
Choice D rationale:
A board game is typically too complex for a 3-year-old to fully enjoy and understand. Board games often require following rules, taking turns, and using fine motor skills that may not be well-developed in a child of this age. Therefore, it is not the most appropriate choice.
Correct Answer is D
Explanation
Choice A rationale:
Offering a variety of items to choose from to stimulate the toddler's mind is a good practice, but it doesn't necessarily encourage independence. It provides opportunities for exploration and learning but doesn't directly promote decision-making and self-sufficiency.
Choice B rationale:
Allowing the child to determine their own daily routine can be challenging and may not always be practical. It's important to strike a balance between independence and structure to ensure the child's safety and well-being.
Choice C rationale:
Setting the routine herself but discussing with her toddler how he or she would have done it differently is a reasonable approach, but it may not always lead to increased independence. It can be a step in the right direction but doesn't directly encourage independence in decision-making.
Choice D rationale:
Offering the child a choice between two items is an effective way to encourage independence. It allows the toddler to make decisions and feel a sense of control over their choices, fostering a sense of independence and autonomy. This approach is often used in parenting to promote decision-making skills in toddlers. .
