Answer:
The client
Step-by-step explanation:
We can consider that primary information is nothing more than the source of the information, ie the exact place where all other necessary information will be taken. Based on this, we can state that if the nurse wants to update the client's health history, she will have to look for the client's necessary information, because she is the one who knows the new data that needs to enter her health history. With this, we can conclude that the customer represents the primary information, as it will be the source of all necessary information.
