单选题 An elderly client's lithium level is 1.4 mEq/L. She complains of diarrhea, tremors, and nausea. The nurse's first action is to

A、 hold the lithium (Lithobid) and notify the physician.
B、 reassure the client that these are normal adverse effects.
C、 administer another lithium dose.
D、 discontinue the lithium.

【正确答案】 A

【答案解析】The client has symptoms of lithium toxicity. Therefore, her lithium should be held and the physician notified immediately. These aren't normal adverse effects, and administering another dose would increase the toxic effects. A nurse can't discontinue a medication without a physician's order.
