A boy who has fractured his forearm is unable to extend his fingers. The nurse knows that this
may indicate damage to the epiphyseal plate.
is normal following this type of injury.
may indicate compartment syndrome.
may indicate fat embolism.
The Correct Answer is C
Compartment syndrome is a condition that can occur following an injury, such as a fracture, where there is increased pressure within a closed space (compartment) in the body. In the case of a forearm fracture, swelling and increased pressure within the compartment can lead to compression of the nerves and blood vessels, resulting in symptoms such as pain, numbness, and decreased function of the affected muscles.
The inability to extend the fingers suggests impairment of the extensor muscles, which are innervated by the radial nerve. If the radial nerve is compressed or injured due to compartment syndrome, it can result in a loss of function in the muscles it innervates, leading to the inability to extend the fingers.
damage to the epiphyseal plate in (option A) is incorrect because it, is not related to the inability to extend the fingers. The epiphyseal plate is the growth plate in long bones, and damage to it would typically affect bone growth rather than finger extension.
, stating that it is normal following this type of injury in (option B), is incorrect. Inability to extend the fingers is not a normal or expected finding after a forearm fracture. It suggests a potential complication or underlying issue.
fat embolism in (option D) is incorrect because it, is unlikely to cause an inability to extend the fingers. Fat embolism occurs when fat globules from a broken bone enter the bloodstream and can lead to respiratory and neurological symptoms, but it would not specifically cause an isolated loss of finger extension.

Correct Answer is A
Explanation
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 B
Explanation
These symptoms are indicative of hypoglycaemia, which occurs when the blood sugar levels drop too low. Providing a source of fast-acting carbohydrates, such as orange juice, can quickly raise the child's blood sugar levels and alleviate the symptoms.
Administering insulin (Option A) is incorrect because it is not appropriate in this situation because it would further lower the child's blood sugar levels.
Offering water (Option C) is incorrect because it would not effectively address the low blood sugar.
Glucagon (Option D) is incorrect because it is typically used in severe cases of hypoglycaemia when the child is unconscious or unable to swallow, and it requires a prescription. In this case, providing orange juice is the safest and most appropriate initial intervention. However, it is important to seek medical attention and inform the child's healthcare provider about the incident.
