A nurse is explaining to parents how the central nervous system of a child differs from that of an adult. Which statement accurately describes these differences?
The brain of a term infant weighs less than half of the weight of the adult brain.
The infant has 150 mL of CSF compared with 50 mL in the adult.
Coordination and fine motor skills develop as myelinization of peripheral nerves progresses.
Papilledema is a common manifestation of ICP in the very young child.
The Correct Answer is A
The statement that accurately describes the difference between the central nervous system (CNS) of a child and an adult is option A. The brain of a term infant weighs less than half of the weight of the adult brain. The brain undergoes significant growth and development during childhood and continues to develop until early adulthood. At birth, the brain is only a fraction of its adult weight, and it continues to grow and mature over time.
infant has 150 mL of cerebrospinal fluid (CSF) compared with 50 mL in the adult in (option B), is incorrect. The volume of CSF in the CNS is not a significant difference between children and adults.
coordination and fine motor skills develop as myelination of peripheral nerves progresses in (option C), is an incorrect statement. Myelination is an ongoing process that occurs throughout childhood and contributes to the development of coordination and fine motor skills.
papilledema is a common manifestation of increased intracranial pressure (ICP) in the very young child in (option D), is not correct. Papilledema refers to swelling of the optic disc and is not commonly seen in very young children. Signs of increased ICP in young children may present differently compared to adults and can include altered mental status, irritability, vomiting, and changes in vital signs.

Correct Answer is C
Explanation
The most important factor in determining the rate of fluid replacement in a dehydrated child
is urine output. Urine output is a crucial indicator of renal perfusion and hydration status.
Monitoring urine output allows healthcare professionals to assess the child's response to fluid
replacement therapy and adjust the rate accordingly.
The type of dehydration in (Option A) is incorrect. The type of dehydration, is important in
determining the appropriate fluid composition for rehydration but does not directly dictate the
rate of fluid replacement.
The child’s weight in (Option B) is incorrect. The child's weight, is considered when
calculating the maintenance fluid requirements, but it does not solely determine the rate of
fluid replacement for dehydration.
Serum potassium level in (Option D) is incorrect. The serum potassium level, is important to
monitor in a dehydrated child, especially in cases of severe dehydration, as electrolyte
imbalances may occur. However, it is not the most important factor in determining the rate of
fluid replacement. Fluid replacement is primarily guided by assessing the child's hydration
status through parameters such as urine output and clinical assessment.
Correct Answer is C
Explanation
Upper extremity fractures in children commonly occur as a result of falls. Children are more prone to falls due to their developing motor skills, balance, and coordination. They may fall from playground equipment, bicycles, or simply while running or playing.
While sports injuries (Option A) can also lead to upper extremity fractures, falls are generally the most common cause in children.
Physical abuse (Option B) is an unfortunate possibility in some cases, but it is important to approach the assessment without assuming abuse as the cause without appropriate evidence or disclosure.
Upper extremity fractures resulting from automobile crashes (Option D) are less common in children compared to falls or sports injuries, although they can occur in severe accidents.
It is always important for the nurse to assess the child's history, obtain a detailed account of the injury, and consider any additional signs or indications that may suggest non-accidental trauma if appropriate.
