The management of indwelling urinary catheters requires strict adherence to evidence-based practices to prevent catheter-associated urinary tract infections. This scenario involves applying knowledge of aseptic technique, mechanical drainage patency, and the prevention of bacterial colonization within the urinary system.

Choice A rationale

Regular irrigation increases the risk of introducing pathogens into the sterile urinary tract by breaking the closed drainage system. Irrigation is only indicated for obstructions, such as blood clots, to maintain necessary catheter patency.

Choice B rationale

Daily perineal care should be performed with soap and water rather than antiseptic solutions. Antiseptics can irritate the urethral meatus and disrupt normal flora, potentially increasing the risk of bacterial overgrowth and subsequent infection.

Choice C rationale

Maintaining a prompt and unobstructed flow of urine is vital. Kinks or twists cause urine stasis, which allows bacteria to migrate upward into the bladder, significantly increasing the risk of developing a urinary tract infection.

Choice D rationale

Catheters should only be replaced based on clinical indications, such as obstruction or infection, not on a fixed schedule. Frequent, unnecessary changes increase the risk of urethral trauma and the introduction of exogenous microorganisms.

Pyloric obstruction involves a mechanical blockage at the stomach outlet, leading to the accumulation of gastric contents. Knowledge of gastrointestinal decompression and the therapeutic purpose of nasogastric tubes in managing increased intragastric pressure and preventing emesis is required here.

Choice A rationale

Pyloric obstruction causes gastric stasis and distension because contents cannot enter the duodenum. Nasogastric intubation provides decompression by removing accumulated secretions and gas, which relieves pressure, prevents vomiting, and reduces the risk of aspiration in the client.

Choice B rationale

Providing nutrition via tube feeding is contraindicated in pyloric obstruction. Because the outlet of the stomach is blocked, any enteral formula introduced would accumulate in the stomach, worsening distension and significantly increasing the risk of reflux or aspiration.

Choice C rationale

While gastric pH can be measured via a nasogastric tube, it is not the primary therapeutic rationale for tube placement in a client with a mechanical obstruction. Decompression is a critical intervention to ensure safety and comfort.

Choice D rationale

Administering oral medications through a nasogastric tube is ineffective during an obstruction. The medication cannot pass the pylorus to be absorbed in the small intestine, and it adds volume to an already overfilled and pressurized stomach.
