The nurse should monitor the temperature of the environment of a client who becomes easily agitated, with awareness that increased temperatures sometimes may cause the client to become:

Choice A rationale: Clozapine has no effect on a patient’s blood pressure levels. However, blood pressure monitoring for all patients is crucial but the temperature is more relevant for a patient on clozapine.
Choice B rationale: Clozapine has no effect on an individual’s respiratory rate hence in this case it is not the priority vital sign to monitor.
Choice C rationale: Clozapine use does not cause pain. Furthermore, pain is not a vital sign.
Choice D rationale: One of the side effects of clozapine is agranulocytosis hence this predisposes the patient to infections which may manifest with fever. Therefore, it is important to monitor the patient’s temperature while on treatment.

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.
