administer the next dose of lithium when it is due
observe the client for confusion and slurred speech
Numbers 1, 2, and 5 are correct.
Lithium has a narrow therapeutic range of 0.6 to 1.2 mEq/L. A level of 2.2 mEq/L indicates moderate toxicity. The nurse should notify the health care provider immediately, as severe toxicity can cause tonic-clonic seizures, coma, or death. Treatment typically involves administering IV fluids to dilute the concentration of the medication, holding the medication, and possible hemodialysis in severe cases. The client may exhibit signs of toxicity such as confusion, slurred speech, and severe diarrhea. A mechanical soft diet will not treat the toxicity. The nurse would hold the next dose and prepare to draw lab work, including lithium and electrolyte levels, BUN and creatinine, and a CBC.
