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 A
Explanation
The nurse's best response to the parents of a 10-year-old child newly diagnosed with type 1
diabetes mellitus, who are concerned about the child's continued participation in soccer, is to
reassure them that it is generally safe for the child to play sports such as soccer unless the
weather is too hot.
Regular physical activity, including participation in sports, is generally encouraged for
children with type 1 diabetes as long as certain precautions are taken. It is important for the
child to have a well-managed diabetes management plan in place, which may include
monitoring blood sugar levels before, during, and after physical activity, adjusting insulin
doses as necessary, and having appropriate snacks available to maintain blood sugar levels.
Option B, suggesting the swim team as an alternative to soccer, may be a viable option if the
child or parents prefer swimming or if the child has specific concerns related to soccer.
However, it is not the best response to the parents' concern about the child's continued
participation in soccer.
Option C, recommending an extra carbohydrate snack before soccer practice, is a valid
suggestion to help maintain the child's blood sugar levels during physical activity. However,
it should be part of a comprehensive diabetes management plan and not the sole response to
the parents' concern.
Option D, encouraging intellectual activity rather than participation in sports, is not
appropriate as physical activity is generally beneficial for children with type 1 diabetes, as
long as appropriate precautions are taken.
Correct Answer is D
Explanation
In this scenario, the child's increased urination after a serious motor vehicle crash may
indicate a potential issue with fluid balance. Monitoring the child's intake and output is the
priority action for the nurse. This involves accurately measuring and recording the fluids the
child consumes (intake) and the fluids the child eliminates through urine, sweat, and other
sources (output). By closely monitoring the child's intake and output, the nurse can assess the
child's fluid status and identify any abnormalities or imbalances that may require further
intervention.
Restrict dietary sodium intake in (option A) is incorrect because restricting dietary sodium
intake, may be necessary in certain situations, such as if the child has a known sodium
imbalance or hypertension. However, it is not the priority action in this scenario.
Assess the daily serum sodium level in (option B) is incorrect because assessing the daily
serum sodium level, is important to evaluate the child's electrolyte balance. However, it is not
the priority action compared to monitoring the child's intake and output.
Weigh the child daily in (option C) is incorrect because weighing the child daily, is a useful
measure to assess changes in fluid balance. However, it is not the priority action in this
scenario compared to monitoring the child's intake and output, which provides real-time
information on fluid balance.
