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
Intussusception is a medical condition where a portion of the intestine telescopes into an adjacent section, causing an obstruction. This obstruction can affect the normal passage of stool through the intestine.
In intussusception, the obstructed intestine can lead to the development of blood and mucus within the stool, giving it a characteristic appearance described as "currant jelly." The stool may contain a combination of blood, mucus, and faecal matter, resembling the colour and consistency of currant jelly.
loose, foul-smelling stools in (option) is incorrect because it, is not specific to intussusception and can be associated with various gastrointestinal conditions.
hard stools positive for guaiac in (option C) is incorrect because it, is not typical of intussusception. Hard stools and positive guaiac test results are more commonly associated with constipation or other conditions affecting the lower gastrointestinal tract.
ribbon-like stools, in (option D) is incorrect because it may be seen in conditions like colorectal cancer or other obstructive disorders. However, it is not a specific characteristic of intussusception.
In the context of intussusception, the presence of "currant jelly" stools is considered a significant sign and should prompt immediate medical attention. Intussusception is a medical emergency and requires prompt diagnosis and treatment.

Tonic-clonic seizures in (option D) also known as grand mal seizures, is incorrect because itinvolves a combination of muscle rigidity (tonic phase) and jerking movements (clonicphase).
Therefore, based on the description provided, the behaviour of staring into space ischaracteristic of B. Absence seizures. It is important for the child to be evaluated by ahealthcare professional for an accurate diagnosis and appropriate management of theirseizures.
