What is the best nursing action when a child with type 1 diabetes mellitus is sweating, trembling, and pale?

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 anatomy of the urinary tract can influence the susceptibility to urinary tract infections (UTIs). In the case of young girls, their urethra is shorter compared to adult females, which increases the likelihood of bacteria reaching the bladder. The shorter urethra provides a shorter distance for bacteria to travel from the outside of the body to the bladder, making it easier for bacteria to enter and cause an infection.

Prostatic secretions in males in (option A) is incorrect because they are not directly related to the increased susceptibility to UTIs. Prostatic secretions can, however, contribute to conditions like prostatitis, which is an inflammation of the prostate gland that can be associated with urinary symptoms and sometimes bacterial infections.

Frequent emptying of the bladder in (option C) is incorrect because it is generally considered a healthy practice as it helps to flush out any potential bacteria in the urinary tract. It does not predispose the urinary tract to infection.

Increased fluid intake in (option D) is incorrect because it is generally encouraged to maintain proper hydration and urinary tract health. It can help to flush out bacteria from the urinary system, reducing the risk of infection.

While these factors may have implications for urinary tract health, the specific factor that predisposes the urinary tract to infection, particularly in young girls, is the short urethra (B).
