Checking the patency of the nasogastric tube
A nasogastric tube is used after surgery to decompress the stomach and limit tension on the suture line. As another means of limiting pressure on the suture line, oral feedings should not be implemented in the immediate postoperative period when the nasogastric tube is in place. Vomiting indicates obstruction of the nasogastric tube; this is why the initial action should be to check the patency of the tube. It is too soon for signs of infection to occur.

Answer:
Explanation: glutamate and glycine (or D-serine) bind to it, and when activated it allows positively charged ions to flow through the cell membrane. The NMDA receptor is very important for controlling synaptic plasticity and memory function. The NMDAR is a specific type of ionotropic glutamate receptor.
Simpson's Diversity Index is a measure of diversity. In ecology, it is often used to quantify the biodiversity of a habitat. It takes into account the number of species present, as well as the abundance of each species.
In the Simpson index, p is the proportion (n/N) of individuals of one particular species found (n) divided by the total number of individuals found (N), Σ is still the sum of the calculations, and s is the number of species.
