Step-by-step explanation:
The question regarding the time required to scrub the arm of a donor who is sensitive to iodine does not have enough context to provide a definitive answer. However, typically, antiseptic scrub times with an alternative to iodine (such as chlorhexidine or alcohol-based solutions for individuals with iodine sensitivity) should follow the specific product's instructions. Generally, antiseptic scrubs can range from 30 seconds to 3 minutes, depending on the protocol and product being used. It is important for health professionals to be aware of the individual's sensitivities and to select the appropriate antiseptic agent that provides effective disinfection while ensuring patient safety.
Regarding the increase in urine output after drinking a large glass of water, it usually starts within about 30 minutes as the body begins to process the fluids that have been ingested.
