When does the posterior fontanelle close?
3 to 6 months.
6 to 9 months.
9 to 12 months.
2 to 3 months.
The Correct Answer is D
The correct answer is D. 2 to 3 months.
Choice A rationale:
The posterior fontanelle does not close within 3 to 6 months of birth. This timeframe is too long for the typical closure of the posterior fontanelle.
Choice B rationale:
Similarly, the posterior fontanelle does not close within 6 to 9 months of birth. This period is beyond the usual closure time for the posterior fontanelle.
Choice C rationale:
The posterior fontanelle does not close within 9 to 12 months of birth. This timeframe is significantly longer than the typical closure period for the posterior fontanelle.
Choice D rationale:
The posterior fontanelle typically closes within 2 to 3 months of birth. This is the correct timeframe for the closure of the posterior fontanelle.

Correct Answer is C
Explanation
Choice A rationale:
Speaking in 2-word sentences is not a developmental milestone expected in a 9-month-old infant. Language development typically involves babbling, imitating sounds, and understanding simple commands at this age.
Choice B rationale:
Beginning to use a spoon rather sloppily is also not a typical milestone for a 9-month-old. Infants at this age are just starting to explore solid foods and are more likely to use their hands for self-feeding.
Choice C rationale:
Creeping along the floor is an appropriate developmental milestone for a 9-month-old. This crawling or creeping motion is a precursor to crawling and walking. It's a sign of motor development and exploration.
Choice D rationale:
Grasping objects with a palmar grasp is a skill that infants typically develop at a much younger age, usually within the first few months of life. By 9 months, they should have progressed to a more refined pincer grasp.
Correct Answer is A
Explanation
Choice A rationale:
Young children often understand that other people die, but do not equate it with themselves. Young children typically begin to grasp the concept of death, but they often don't fully understand it in the same way adults do. Their understanding of death tends to be more external, and they may not relate it to themselves. The nurse's response should be guided by this understanding because it helps in communicating with and supporting children when they encounter the death of a loved one. By recognizing that children may not see death as an immediate threat to themselves, the nurse can provide age-appropriate explanations and reassurance, addressing the child's concerns and fears. It's crucial to be sensitive to the child's emotional state and offer comfort and support as needed.
Choice B rationale:
Children can understand the concept of a higher being much like adults can. While children may have some understanding of the concept of a higher being, their understanding is often simpler and less abstract than that of adults. It's important for the nurse to acknowledge a child's spirituality and beliefs when discussing death, but it's not the primary understanding that guides the nurse's response. The primary focus should be on the child's understanding of death itself and how it may affect them or their loved ones.
Choice C rationale:
The children's response will depend entirely on whether they have been acquainted with death before this. While prior exposure to death may influence a child's response, it is not the sole determining factor. Even children who have not experienced death before may still have various emotional reactions when a loved one dies. The nurse should approach each child individually, taking into consideration their unique experiences and emotions rather than relying solely on past exposure to death.
Choice D rationale:
Children are unlikely to notice their grandmother's absence if no one reminds them. This choice is not an appropriate understanding to guide the nurse's response. Children are likely to notice the absence of a loved one, especially a grandmother, regardless of whether someone reminds them. They may not fully understand the implications of death, but they will notice the change in their daily life and routines. It is essential to support and communicate with them during this period rather than assume they won't notice the absence.
