To prevent the occurrence of Lithium (Eskalith) toxicity, the nurse should teach the client to maintain adequate intake of
Chloride and sodium
Water and vitamins
Sodium and water
Potassium and water
The Correct Answer is C
Choice A rationale: Both sodium and chloride are important for fluid balance but chloride has no effect on the blood lithium levels.
Choice B rationale: sodium has an effect on the blood lithium levels by competing with lithium for reabsorption in the kidneys but vitamins do not influence the lithium levels in blood.
Choice C rationale: dehydration increases the risk of lithium toxicity since it will result in oliguria hence increasing the risk of lithium toxicity since the drug is primarily excreted in urine. Sodium and lithium compete for reabsorption in the kidneys, so low sodium levels can increase lithium retention and lead to toxicity. Therefore, the client should maintain an adequate intake of sodium and water to prevent dehydration and sodium loss and to keep the lithium level within the therapeutic range.
Choice D rationale: water has an influence on blood lithium levels since adequate intake minimizes the risk of toxicity by increasing the drug’s excretion in urine.
However, potassium does not compete with lithium for reabsorption.

Explanation
Choice A rationale: this is a type of delusion involving the misinterpretation of random events as having personal significance or reference.
Choice B rationale: flight of ideas refers to a disordered thinking process involving rapid shifts from one topic to another. The client’s speech is often incoherent and difficult to follow.
Choice C rationale: this is a type of memory distortion involving the fabrication of stories or details to fill the gaps in an individual’s memory. Usually occurs in conditions such as dementia, substance abuse, and brain damage.
Choice D rationale: this refers to the repetition of the same word, phrase, or action over and over without being able to stop or switch to something else. Occurs in conditions such as schizophrenia, brain injury, or a stroke.

Correct Answer is D
Explanation
Choice A rationale: this may imply that the client is not cooperating and may make them feel guilty thus discouraging any further communication which may be useful in generating a treatment plan for the patient.
Choice B rationale: assuming that the client has completed her conversation is incorrect since it is an opportunity to explore the client’s feelings and thoughts that may be missed.
Choice C rationale: this is not the best action since it may interrupt the client’s natural process of reflection and expression while pressuring him/her to respond to the questions asked.
Choice D rationale: remaining silent and being attentive to the client’s nonverbal communication shows respect for the client’s pace and readiness to speak.
Furthermore, it demonstrates the nurse’s presence and their support.
