A client asks a nurse about the use of vitamin C to prevent urinary tract infection. The nurse states that the function of vitamin C is to:

Flush the bladder with antioxidants.

Acidify the urine.

coli from adhering to the bladder wall.

Coat the bladder lining.

Answer and Explanation

The Correct Answer is B

Choice A rationale

While antioxidants can benefit overall health, they do not specifically target the urinary tract or provide the mechanism needed to prevent urinary tract infections.

Choice B rationale

Vitamin C (ascorbic acid) can acidify the urine, creating a less hospitable environment for bacteria, including those causing urinary tract infections (UTIs).

Choice C rationale

Preventing E. coli adhesion to the bladder wall is a specific function of other substances like cranberry juice, not vitamin C. Therefore, this choice does not align with vitamin C's function.

Choice D rationale

Coating the bladder lining is not a known function of vitamin C. Other medical treatments or substances would be needed for this purpose, making this choice incorrect.

Correct Answer is C

Explanation

Choice A rationale

Hemoglobin levels indicate general blood health but do not directly reflect nutritional status or TPN effectiveness.

Choice B rationale

Serum calcium levels reflect calcium metabolism, not overall nutritional status or the effectiveness of TPN.

Choice C rationale

Pre-albumin levels provide a sensitive indicator of nutritional status and protein synthesis, showing TPN effectiveness in improving nutrition.

Choice D rationale

Cholesterol levels can be influenced by various factors and do not specifically reflect the effectiveness of TPN in improving nutritional status. .

A. Fecal-smelling breath. B. Severe abdominal distention. C. Weakness, weight loss, and anorexia. D. High-pitched tinkling bowel sounds. E. Intense thirst.

Correct Answer is ["A","B","D"]

Explanation

Choice A rationale

Fecal-smelling breath is a symptom of small intestine obstruction due to bacterial fermentation of trapped food, which produces a foul odor that can be detected on the breath.

Choice B rationale

Severe abdominal distention occurs in small intestine obstructions because of the accumulation of gas and fluids proximal to the obstruction site, leading to a noticeable increase in abdominal girth.

Choice C rationale

Weakness, weight loss, and anorexia are more characteristic of chronic gastrointestinal conditions rather than acute small intestine obstruction. These symptoms develop over a longer period and are not acute manifestations.

Choice D rationale

High-pitched tinkling bowel sounds are a typical finding in small intestine obstruction. They occur due to increased peristaltic activity proximal to the obstruction site as the intestines attempt to move the obstructed contents.

Choice E rationale

Intense thirst is not a primary manifestation of small intestine obstruction. While dehydration can occur, it is not specific to small intestine obstruction and can be a result of many other conditions.
