(From external source) Which of the following practices can help prevent gastroenteritis?

Choice A rationale:

Chest X-ray is not appropriate for identifying the causative agent of gastroenteritis. It primarily helps visualize lung and chest conditions.

Choice B rationale:

Blood culture is used to detect bacterial or fungal infections in the bloodstream, not specifically for identifying the causative agent of gastroenteritis.

Choice C rationale:

Stool analysis is the most suitable diagnostic test for identifying the specific causative agent of gastroenteritis. It can detect pathogens, such as bacteria, viruses, and parasites, in the stool sample.

Choice D rationale:

Urinalysis is not the most appropriate test for identifying the causative agent of gastroenteritis. It is used to assess kidney function and detect urinary tract infections.

Choice A rationale:

Hypertension and tachycardia are not typical signs of dehydration. Dehydration often leads to decreased blood volume, resulting in hypotension and tachycardia as the body tries to compensate for the fluid loss.

Choice B rationale:

Bradycardia and pale skin are not consistent with dehydration. Dehydration usually leads to an increased heart rate (tachycardia) as the body attempts to maintain circulation despite decreased fluid levels.

Choice C rationale:

Increased urine output is not indicative of dehydration. Dehydration typically leads to decreased urine output (oliguria) as the body conserves fluid in response to the loss.

Choice D rationale:

Dry mucous membranes and sunken eyes are classic signs of dehydration. When fluid intake is insufficient, the body conserves water by reducing saliva and other secretions, resulting in dry mucous membranes. Sunken eyes can occur due to decreased fluid volume and loss of tissue turgor.
