Common problems in a therapeutic relationship include all of the following except

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.

Choice A rationale: Abstract thinking involves the ability to think conceptually and comprehend concrete concepts such as proverbs.
Choice B rationale: Memory assesses the client’s ability to recall previously experienced or learned information and is not directly assessed by the client's ability to follow a written command.
Choice C rationale: General knowledge refers to the ability of a client to answer questions on common topics and facts and is not assessed by the client's response to a written command.
Choice D rationale: The ability to follow a written command, such as "Please raise your left hand," assesses the client's ability to read and understand written instructions.
