The nurse is explaining Tanner staging to an adolescent and mother. Which statement best describes Tanner staging?
Staging of puberty based on the initiation of primary sexual characteristics
Predictable stages of puberty based on primary and secondary sexual characteristics
Staging of puberty based on the initiation of menarche and nocturnal emissions
Predictable stages of puberty that are based on chronologic age
The Correct Answer is B
The statement that best describes Tanner staging is option B. Tanner staging is a system used
to classify and assess the progression of puberty based on the development of both primary
and secondary sexual characteristics. It provides a framework for evaluating the physical
changes that occur during puberty, such as breast development in females, testicular
enlargement in males, pubic hair growth, and other secondary sexual characteristics. The
Tanner staging system includes several stages that represent the sequential progression of
puberty in individuals.
staging of puberty based on the initiation of primary sexual characteristics in (option A) is not
correct because it, does not encompass the full scope of Tanner staging, as it does not
consider the progression of secondary sexual characteristics.
staging of puberty based on the initiation of menarche (the onset of menstruation) and
nocturnal emissions, in (option C) is not correct. While menarche and nocturnal emissions are
significant events that occur during puberty, they do not encompass the entire Tanner staging
system, which involves a broader range of physical changes.
predictable stages of puberty based on chronologic age, in (option D) is not correct. Tanner
staging is based on the progression of physical changes and sexual maturation, rather than
being solely determined by chronological age. Puberty can vary in onset and duration among
individuals, making chronological age an unreliable indicator of pubertal development.

Correct Answer is C
Explanation
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
The most important factor in determining the rate of fluid replacement in a dehydrated child
is urine output. Urine output is a crucial indicator of renal perfusion and hydration status.
Monitoring urine output allows healthcare professionals to assess the child's response to fluid
replacement therapy and adjust the rate accordingly.
The type of dehydration in (Option A) is incorrect. The type of dehydration, is important in
determining the appropriate fluid composition for rehydration but does not directly dictate the
rate of fluid replacement.
The child’s weight in (Option B) is incorrect. The child's weight, is considered when
calculating the maintenance fluid requirements, but it does not solely determine the rate of
fluid replacement for dehydration.
Serum potassium level in (Option D) is incorrect. The serum potassium level, is important to
monitor in a dehydrated child, especially in cases of severe dehydration, as electrolyte
imbalances may occur. However, it is not the most important factor in determining the rate of
fluid replacement. Fluid replacement is primarily guided by assessing the child's hydration
status through parameters such as urine output and clinical assessment.
