Rationale: The correct answer is to change the administration set every 72 to 96 hours. This practice helps reduce the risk of infection by preventing the build-up of bacteria in the tubing. Changing the set too frequently (choices A, B, and C) may increase the chances of contamination and infection without providing additional benefits. Therefore, the LPN should follow the guideline of changing the administration set every 72 to 96 hours to maintain the client's safety during the continuous intravenous normal saline infusion.

Emptying the urinal contents into the 24-hour collection container (Choice C) assumes prior knowledge on the client's part and skips the critical step of ensuring comprehension. Discarding the contents of the urinal (Choice D) is incorrect and wasteful since the urine is necessary for the 24-hour collection process.

Choice D is incorrect because athlete's foot is caused by a fungal infection, not lice.
