Which factor predisposes the urinary tract to infection?
Prostatic secretions in males
Short urethra in young girls
Frequent emptying of the bladder
increased fluid intake
The Correct Answer is B
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).

, scoliosis in (option D), refers to an abnormal sideways curvature of the spine, typically in an "S" or "C" shape. It is different from kyphosis, which primarily affects the thoracic spine and results in a rounded upper back.
Correct Answer is D
Explanation
The first sign of pubertal change seen with boys is testicular enlargement. This is known as testicular or scrotal growth and is one of the earliest physical signs of puberty in boys. Testicular enlargement is followed by other changes such as the growth of pubic hair, penile growth, voice deepening, and facial hair growth.
voice deepening in (option A) is incorrect because it, typically occurs after testicular enlargement and is associated with the growth and development of the larynx during puberty.
scrotal enlargement in (option B) is incorrect because it, may occur simultaneously or shortly after testicular enlargement as part of overall genital growth during puberty.
, facial hair growth in (option C) is incorrect because it, is a later sign of pubertal development in boys and typically occurs after the initial testicular enlargement and growth of pubic hair.
