A client with gastroenteritis is experiencing dehydration. The nurse should monitor for which signs of dehydration?
Hypertension and tachycardia.
Bradycardia and pale skin.
Increased urine output.
Dry mucous membranes and sunken eyes.
The Correct Answer is D
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.

Correct Answer is C
Explanation
Choice A rationale:
Salmonella and Campylobacter are known to cause bacterial gastroenteritis, but they typically do not produce enterotoxins that specifically cause watery diarrhea. Instead, they often cause more inflammatory types of diarrhea.
Choice B rationale:
Shigella and Yersinia can also cause bacterial gastroenteritis, but their mechanisms of causing diarrhea are different from enterotoxin production. Shigella is known to cause bloody diarrhea, while Yersinia can lead to abdominal pain and fever.
Choice C rationale:
Vibrio cholerae produces the cholera toxin, which leads to watery diarrhea by increasing chloride secretion and inhibiting sodium absorption in the intestines. Clostridium perfringens can produce enterotoxins that lead to watery diarrhea and abdominal cramps.
Choice D rationale:
While E. coli can cause gastroenteritis, it usually produces Shiga toxins that lead to bloody diarrhea (as seen in E. coli O157:H7), or it may cause inflammation and not typically result in watery diarrhea. C. difficile is known for causing antibiotic-associated diarrhea and colitis, but it's not primarily associated with watery diarrhea.
Correct Answer is ["A","B","E"]
Explanation
Choice A rationale:
Vital signs are crucial to assess the child's overall condition and the severity of gastroenteritis. Elevated heart rate and decreased blood pressure may indicate dehydration.
Choice B rationale:
Travel history is important to identify potential sources of infection or exposure, which can help determine appropriate treatment and infection control measures.
Choice C rationale:
Urinary output can be monitored to assess the child's hydration status. Decreased urine output may indicate dehydration.
Choice D rationale:
Blood glucose level, while relevant in some medical conditions, is not a primary consideration in the assessment of gastroenteritis.
Choice E rationale:
Skin turgor reflects the degree of dehydration. Poor skin turgor may indicate significant fluid loss.
