What is the therapeutic range of Lithium (Eskalith)?
0.6-1.5
0.1-0.5
0.2-0.5
0.4-1.6
The Correct Answer is A
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.

Explanation
Choice A rationale: this response is dismissive of the patient’s feelings and concerns and does not acknowledge the patient’s reality and perspective. It implies that the patient is overreacting and may make the client feel judged and ignored.
Choice B rationale: this response is intrusive and prescriptive since the patient’s reasons and preferences are not considered. it assumes that the patient has a husband and that they have a good relationship together which may not be the case.
Choice C rationale: this response is accusatory and confrontational while implying that the patient’s behavior was wrong and unacceptable. Furthermore, it focuses on the past rather than the present or the future which is relevant in this case. It also makes the patient feel guilty and ashamed which may impair their ability to open up hence ineffective care.
Choice D rationale: This response is empathic and validating. It reflects the patient's feelings and shows understanding and compassion. It does not judge or minimize the patient's emotions, and it invites the patient to share more if they wish. This response could make the patient feel heard, supported, and respected.
Choice E rationale: this response encourages the patient to open up and express their thoughts and feelings. This makes the patient feel valued and empowered thus allowing them to share their feelings at their own pace.
