At what age is sexual development in boys and girls considered to be precocious?

The most appropriate statement by the nurse to a 15-year-old whose friend has mentioned suicide is option A. The statement acknowledges the seriousness of the situation and emphasizes the importance of taking the friend's threat seriously. It also highlights the need for immediate help and intervention. Suicide threats should never be dismissed or taken lightly, and it is crucial to involve professionals who can provide appropriate support and assistance.

"Tell your friend to come to the clinic immediately," in option B is incorrect because places the responsibility solely on the 15-year-old to relay the message to their friend, which may not be the most effective or timely approach.

"If your friend mentions suicide again, get your friend some help," in (option C) is incorrect because it does not address the urgency of the situation. Waiting for the friend to mention suicide again before acting may lead to potential harm.

"You need to gather details about your friend's suicide plan," is incorrect because places the responsibility on the 15-year-old to gather information about the friend's suicidal intentions. While understanding the situation and obtaining relevant details is important, the immediate priority is ensuring the friend's safety and seeking professional help.

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.
