Document Summary
Random facts: if you bring the serum na up too quickly, the na will act as an osmotic agent to draw water out of the cell. A rate of 50ml/hr is pretty slow , so this would be ok. A rate of 200ml/hr is really fast. : if your pt is npo, look at how long they have been npo and what type of iv fluid she"s been receiving. The sugar in the blood stream acts as an osmotic agent and will pull water into the cell. The hypothalamus senses dehydration and makes the pt very thirsty so they"ll drink a lot of water and secret adh. This will cause the serum na to drop: every 100 increase in glucose cause the na to drop by 2. The high bs involved with dka is pulling the water out of the cells so the pt is extremely dehydrated.
