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:
If a 16-month-old child is unable to climb steps, it may not be a significant cause for concern at this age. Climbing steps is a complex motor skill that children typically develop later in toddlerhood.
Choice B rationale:
Preferring finger feeding at 16 months is not necessarily a cause for concern. Many children continue to use finger feeding even when they have started using utensils. This can be part of their developmental process.
Choice C rationale:
A 16-month-old child not walking independently is a significant concern. By this age, most children should be taking their first independent steps or showing signs of readiness to walk. Delayed independent walking can be a sign of developmental issues, and it is essential to address this with a healthcare provider.
Choice D rationale:
Limited to single words is also a developmental milestone concern, but it may not be as immediate a concern as not walking independently. Many children develop language skills at different rates, and limited vocabulary at 16 months may not be as alarming as a delay in motor skills like walking.
Correct Answer is C
Explanation
Choice A rationale:
Allowing the child to read in his room until he falls asleep may not be the most appropriate choice in this situation. While reading can be a calming bedtime activity, it might not address the underlying issue of establishing a consistent bedtime routine. Additionally, letting a child read until they fall asleep could lead to irregular sleep patterns.
Choice B rationale:
Tiring out the child with physical activity before bedtime might seem like a good idea to promote sleep, but it's not always effective for all children. Physical activity close to bedtime may have the opposite effect, making the child more alert and active. It's essential to focus on a combination of calming activities and a consistent bedtime routine.
Choice D rationale:
Allowing the child to put himself to bed when he is tired can lead to inconsistent sleep patterns and may not be suitable for a young child. Children thrive on routine and structure, and it's important to establish a bedtime routine that provides a sense of security and predictability. Allowing a child to decide when to go to bed can disrupt this routine.
