ATI RN Fundamentals 2023 Exam 3 | Nurselytic

Correct Answer: B

Rationale: The correct answer is B: Keep the collection bag below bladder level. This is important to prevent backflow of urine into the bladder, reducing the risk of catheter-associated urinary tract infections. Keeping the collection bag below bladder level ensures continuous drainage and minimizes the risk of bacterial contamination. This practice maintains a unidirectional flow and prevents retrograde movement of bacteria from the collection bag back into the bladder.

Choice A is incorrect because disconnecting the drainage tube for irrigation increases the risk of introducing bacteria into the urinary system.

Choice C is incorrect because using a size 20 French catheter is not directly related to preventing catheter-associated urinary tract infections.

Choice D is incorrect because allowing the drainage bag to fill completely increases the risk of bacterial growth and infection.
