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
When caring for a child with an open fracture, the nurse should carefully assess for signs and symptoms of infection. An open fracture refers to a fracture where the bone is exposed through the skin, creating a direct pathway for microorganisms to enter and cause infection. Infection is a significant concern in open fractures and can lead to serious complications if not identified and treated promptly. Signs of infection may include increased pain, swelling, redness, warmth, purulent drainage, fever, or systemic signs of infection such as elevated white blood cell count.
Osteoarthritis in (option A) is incorrect because it, is not an immediate concern in the care of a child with an open fracture. Osteoarthritis refers to degenerative joint disease that typically develops over time and is not directly related to the acute management of an open fracture.
epiphyseal disruption in (option B) is incorrect because it, refers to an injury involving the growth plate (epiphyseal plate) that can affect bone growth and development. While it is a potential concern in fractures that involve the growth plate, it is not specific to open fractures and may not be an immediate priority in the initial assessment of an open fracture.
periosteum thickening in (option D) is incorrect because it, may occur in response to injury and fracture healing, but it is not specifically associated with open fractures and is not a primary focus in the initial assessment of an open fracture.
Correct Answer is C
Explanation
Hypoglycaemia is characterized by low blood sugar levels. In children, symptoms of hypoglycaemia can vary, but irritability is a common sign. Other signs and symptoms of hypoglycaemia in children may include sweating, trembling, pale skin, hunger, weakness, confusion, and dizziness.
Normal sensorium and serum glucose greater than 160 mg/dL in (Option A) is incorrect because a normal sensorium (normal level of consciousness) and a serum glucose level greater than 160 mg/dL would not be indicative of hypoglycaemia.
Urine positive for ketones and serum glucose greater than 300 mg/dL in (Option B) is incorrect because it describes characteristics of hyperglycaemia (high blood sugar levels) rather than hypoglycaemia. Positive urine ketones and a serum glucose level greater than 300 mg/dL are commonly seen in diabetic ketoacidosis, a complication of high blood sugar levels in diabetes.
Increased urination and serum glucose less than 120 mg/dL in (Option D) is incorrect because it describes increased urination and a serum glucose level less than 120 mg/dL. While a serum glucose level less than 120 mg/dL could indicate hypoglycaemia, increased urination is not a typical sign of hypoglycaemia. Increased urination may be seen in conditions such as diabetes mellitus when blood sugar levels are consistently high.
