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 D

Explanation

Choice A rationale

This statement is confrontational and does not provide clear boundaries or expectations for acceptable behavior.

Choice B rationale

Asking about medications does not address the inappropriate behavior and may further escalate the situation.

This response is defensive and may provoke further aggression from the client.

Choice D rationale

This statement acknowledges the client's feelings while clearly setting a boundary for unacceptable behavior, promoting a safe environment.

A. Triple lumen subclavian catheter inserted to the right subclavian area. B. Double lumen PICC inserted above the antecubital fossa. C. A small bore nasogastric tube inserted into the right nare. D. A 22-gauge peripheral IV inserted to the dorsum of the left hand. E. An 18-gauge peripheral IV inserted to the left forearm.

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

Explanation

Choice A rationale

A triple lumen subclavian catheter provides a reliable, large-bore central line for infusing TPN, ensuring safe and efficient nutrient delivery to meet metabolic needs.

Choice B rationale

A double lumen PICC line inserted above the antecubital fossa is suitable for TPN infusion, providing central venous access with reduced infection risk compared to peripheral lines.

Choice C rationale

A nasogastric tube is used for feeding into the stomach or intestine, not for TPN, which requires central venous access to avoid phlebitis and ensure adequate nutrient delivery.

Choice D rationale

A 22-gauge peripheral IV is not appropriate for TPN, as peripheral lines are more prone to phlebitis and cannot support the high osmolarity of TPN solutions.

Choice E rationale

An 18-gauge peripheral IV is better than a 22-gauge, but peripheral lines in general are not ideal for TPN due to risks like phlebitis and inadequate nutrient delivery.
