Which statement is accurate concerning a child's musculoskeletal system and how it may be different from an adult's?
Their bones have less blood flow.
Growth occurs in children as a result of an increase in the number of muscle fibres.
Infants are at greater risk for fractures because their epiphyseal plates are not fused.
Because soft tissues are resilient in children, dislocations and sprains are less common than in adults.
The Correct Answer is C
Infants and children have open growth plates, also known as epiphyseal plates, at the ends of
their long bones. These plates are responsible for bone growth and are not fully fused until
the child reach skeletal maturity. Due to the presence of open growth plates, infants and
children are more prone to fractures because their bones are still developing and are less
dense than those of adults.
Their bones have less blood flow in (Option A) is incorrect because cchildren’s bones
actually have a greater blood flow compared to adults. This increased blood flow supports the
rapid growth and development of bones in children.
Growth occurs in children as a result of an increase in the number of muscle fibers in (option
B) is incorrect because ggrowth in children occurs primarily due to the elongation and
thickening of existing muscle fibres, not an increase in their number. This option inaccurately
suggests that children's muscles increase in fibber count to facilitate growth.
Because soft tissues are resilient in children, dislocations and spirals are less common than in
adults in (Option D is) incorrect. While soft tissues may be more resilient in children, it does
not mean that dislocations and sprains are less common than in adults. In fact, children's
ligaments and joint structures are still developing and may be more susceptible to injuries
such as sprains and dislocations compared to adults.

Correct Answer is C
Explanation
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 C
Explanation
Hydrocephalus refers to a condition characterized by an abnormal accumulation ofcerebrospinal fluid (CSF) within the ventricles of the brain. In infants, hydrocephalus cancause the head to enlarge rapidly as a result of the increased pressure exerted by theaccumulatingfluid.Thisisknownas"rapidheadgrowth."Theincreasedintracranialpressurecanlead to irritabilityand poorappetite in infants.
The distended scalp veins are another common sign of hydrocephalus. As the fluidaccumulates,itputs pressureon thebloodvessels inthe brain,causingtheveinsin thescalptobecome morevisible and distended.
Cerebral palsy in (option A) is incorrect because is a neurological disorder that affects bodymovementandmusclecoordination,butitdoesnottypicallypresentwithrapid headgrowthordistended scalp veins.
Syndrome of inappropriate antidiuretic hormone (SIADH) in (option B) is incorrect becauseitisacondition characterized byexcessivesecretionofantidiuretichormone,leadingtofluidimbalance, but it does not usually cause rapid head growth or distended scalp veins. Reye'ssyndrome (D) is a rare condition that primarily affects the liver and brain, and it does nottypicallypresent with rapid headgrowthor distended scalp veins.
Therefore, based on the signs described, hydrocephalus (C) is the most likely disorder in thiscase.Itisimportantto seekmedicalattentionpromptlyforaproperdiagnosisand appropriatemanagementofhydrocephalus in infants.
