Final answer:
Lithium is an element with 3 protons and electrons. If the level of Lithium is higher than normal, a nurse should assess for symptoms of toxicity, notify the healthcare provider, and monitor the patient's levels.
Step-by-step explanation:
Lithium is an element with an atomic number of 3, meaning it has 3 protons and 3 electrons. In a neutral atom, those 3 electrons are distributed in the first and second energy levels.
If the level of Lithium in the body is higher than normal, the nurse should take action. This may include assessing the patient for symptoms of Lithium toxicity such as vomiting, tremor, confusion, or drowsiness. The nurse should also notify the healthcare provider and closely monitor the patient's Lithium levels to prevent further complications.
