The Client Asks the Nurse Why She Needs to Continue

The client asks the nurse why she needs to continue using table salt because her prescribed lithium (Carbolith) is a salt. What is the best response by the nurse?

A) "The amount is not important; just increase your table salt if you notice signs of lithium (Carbolith) toxicity."
B) "Salt is very important to avoid lithium (Carbolith) toxicity, but not as important as drinking 1 to 1.5 L of water per day."
C) "You must continue to use salt to avoid lithium (Carbolith) toxicity. If you use sea salt, you don't need as much."
D) "You must use table salt or your kidneys will retain lithium (Carbolith) ; and you will become toxic."
