Step-by-step explanation:
The question concerning the duration for which a stump should be elevated to prevent post-operative swelling requires specific medical guidelines for a proper answer. It is essential to follow the surgeon's or physiotherapist's recommendations. In general, elevating the stump can indeed help reduce swelling by aiding venous return and lymphatic drainage. Common advice would be to elevate the limb above the level of the heart for 30 minutes every couple of hours. However, this can vary based on individual cases and the specifics of the surgery, so it's important to adhere to personalized medical advice.
In relation to the reference question about urine output after drinking water: Upon drinking a large glass of water, the body will typically start to increase urine output within 30 minutes to 60 minutes. This is the time it takes for water to be absorbed into the bloodstream, filtered by the kidneys, and then processed into urine.
