What is the most important factor in determining the rate of fluid replacement in the dehydrated child?

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.

A change in status that should alert the nurse to increased intracranial pressure (ICP) in a child with a head injury is confusion and altered mental status. As intracranial pressure increases, it can affect brain function and lead to neurological changes, including confusion, disorientation, irritability, decreased level of consciousness, or other alterations in mental status. These changes indicate that the brain is being compressed and compromised, and immediate intervention is required.

Option B, increased diastolic pressure with narrowing pulse pressure in (option B) is incorrect because it, can be a sign of increased ICP, but it is not specific to head injuries and can be influenced by other factors such as pain, anxiety, or systemic conditions. It is important to consider the overall hemodynamic status of the child and assess for additional signs and symptoms of increased ICP.

irregular, rapid heart rate in (option C), can be a sign of increased ICP, but it is not specific to head injuries and can be influenced by other factors such as pain, anxiety, or other medical conditions. Assessment of heart rate should be considered along with other signs and symptoms of increased ICP.

rapid, shallow breathing, in (option D) can be a sign of increased ICP, but it is not specific to head injuries and can be influenced by other factors such as pain, anxiety, or respiratory conditions. Respiratory assessment should be considered along with other signs and symptoms of increased ICP.
