Choice A rationale: Increased sensitivity to light is a possible side effect of some antipsychotic medications, but it is not necessarily caused by flickering lights.
Choice B rationale: aggression is a symptom of schizophrenia but is not directly triggered by flickering lights.
Choice C rationale: over-stimulation is not caused by flickering lights but can instead be caused by excessive sensory input.
Choice D rationale: Flickering lights may trigger or worsen these hallucinations by creating sensory illusions or distortions, for instance, a client may see shadows, shapes, or colors that are not there.

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.
