When is it generally recommended that a child being treated for acute streptococcal pharyngitis may return to school?

The correct answer is choice A. Wearing cotton underpants.

Choice A rationale:

Wearing cotton underpants is the recommended option to prevent urinary tract infections (UTIs) in young girls. Cotton underpants allow better air circulation, which helps to keep the perineal area dry. This reduces the growth of bacteria and prevents moisture buildup, which are crucial in preventing UTIs. Synthetic fabrics can trap moisture and create a conducive environment for bacterial growth, increasing the risk of UTIs.

Choice B rationale:

Limiting bathing as much as possible is not an appropriate recommendation for preventing UTIs. Hygiene is essential to prevent UTIs, and regular bathing is part of maintaining cleanliness. Overly limiting bathing can lead to poor hygiene practices and may not significantly prevent UTIs, as they are often caused by factors beyond bathing frequency.

Choice C rationale:

Increasing fluids and decreasing salt intake can be beneficial for overall health but may not directly prevent UTIs. While staying hydrated is important for maintaining urinary health, simply increasing fluids and reducing salt intake might not be sufficient to prevent UTIs. Hygiene practices and proper perineal care play a more significant role in preventing UTIs.

Choice D rationale:

Cleansing the perineum with water after voiding is a good hygiene practice, but it alone may not be enough to prevent UTIs. While maintaining cleanliness is crucial, using water to cleanse the perineum after voiding should be combined with other practices, such as wearing cotton underpants and proper wiping techniques, to effectively prevent UTIs.

The correct answer is choice C. Crohn's disease.

Choice A rationale:

Ulcerative colitis is a chronic inflammatory disease that primarily affects the colon and rectum, causing continuous areas of inflammation and ulcers. It does not involve any part of the GI tract from mouth to anus as stated in the question.

Choice B rationale:

Meckel's diverticulum is a congenital condition where a small pouch forms in the lower part of the small intestine. It is not characterized by a chronic inflammatory process involving various parts of the GI tract.

Choice C rationale:

Crohn's disease is a chronic inflammatory disorder that can affect any part of the gastrointestinal tract from mouth to anus. It commonly causes inflammation, ulceration, and narrowing of the affected segments of the intestines. This inflammation can lead to a range of symptoms including abdominal pain, diarrhea, and weight loss. The question accurately describes Crohn's disease.

Choice D rationale:

Irritable bowel syndrome (IBS) is a functional gastrointestinal disorder characterized by abdominal pain or discomfort and changes in bowel habits. It is not associated with chronic inflammatory processes or ulceration as seen in Crohn's disease.
