A client in the mental health unit has a history of Asthma. Which axis would the nurse document this information?

Choice A rationale: The therapeutic range of lithium is generally considered to be 0.6-1.5 mEq/L. However, some patients may require higher or lower levels depending on their individual response to the medication and their clinical condition. Lithium has a narrow therapeutic range hence the blood level of the drug should be closely monitored to minimize the risk of toxicity and sub-therapeutic effects.
Choice B rationale: 0.1-0.5 is too low hence the drug will provide sub-optimal effects thus providing inadequate mood stabilization.
Choice C rationale: 0.2-0.5 is too low hence the drug will provide sub-optimal effects thus providing inadequate mood stabilization.
Choice D rationale: 0.4-1.6 the lower limit is too low and may result in sub-therapeutic effects while the upper limit is too high and increases the risk of lithium toxicity which can manifest as nausea, vomiting, tremors, seizures, and death in severe cases.

Choice A rationale: An observation is a factual statement of what the nurse sees, hears, feels, or smells.
Choice B rationale: This is because the nurse is interpreting the client's behavior and not describing it objectively.
Choice C rationale: subjective data is information that the client tells the nurse, such as feelings, perceptions, or opinions.
Choice D rationale: Objective data is information that the nurse obtains through physical examination, tests, or measurements.
