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 C
Explanation
Choice A rationale:
Educationally oriented play might be suitable for some children, but for a child with moderate intellectual deficiency, focusing on education may not be the most appropriate choice. These children often have developmental delays, so it's important to consider their mental age rather than chronological age when planning activities. Tailoring play to their cognitive abilities can be more effective in promoting their development.
Choice B rationale:
Exercise for leg and arm muscles is a beneficial form of physical activity, but it may not be the most appropriate choice when caring for a child with moderate intellectual deficiency. While physical activity is essential for overall health, it should be combined with play that stimulates cognitive and social development, which is better achieved through age-appropriate play adjusted to their mental age.
Choice D rationale:
Involving a child with moderate intellectual deficiency in contact sports and aggressive physical activities with other children can be unsafe and may not suit their cognitive and physical abilities. These activities may lead to injuries or frustration for the child. It's crucial to focus on play that matches their cognitive level and promotes social and emotional development.
Correct Answer is C
Explanation
On average, most infants triple their birth weight by their first birthday. However, it’s important to note that growth rates can vary widely among different babies due to factors such as genetics and nutrition. Regular check-ups with a healthcare provider can help ensure that an infant’s growth is on track.
