It would lower the pH, raise the acidity of the water, and it would kill off a lot of marine life if it got too high. As species begin to die their predators follow, and this could cause mass extinction.
She could use a control to compare her data to and make sure it is cleaner. Ex. Use the old detergent on ten shirts and then use the new detergent on another ten shirts. She would then compare the shirts she did each detergent on and come up with her conclusion.

The correct answer is that "further teaching on skin care is necessary". This patient is using tepid water to cleanse the area as well as applying ice three times a day. The nurse should educate the patient that the extremes of temperatures are not necessary and should be avoided such as warm to hot water as well as cold water or even ice. Cold water or ice will constrict blood vessels in the area and can produce tissue necrosis by ischemia. Warm to hot water can scald the skin (if hot enough) and even promote the redness as warm water dilates blood vessels.
