A patient is prescribed 150 mg/day of Lithium, divided into two equal doses. How much Lithium should be given per dose?
150 mg.
75 mg.
50 mg.
100 mg.
The Correct Answer is B
Choice A reason: Giving 150 mg in one dose would mean the full daily dose is administered at once, not divided as ordered.
Choice B reason: The total daily dose is 150 mg. Dividing this into two equal doses means 150 ÷ 2 = 75 mg per dose.
Choice C reason: Fifty mg per dose would only total 100 mg per day, which is below the prescribed dose.
Choice D reason: One hundred mg per dose would total 200 mg daily, which exceeds the prescribed 150 mg/day.

Correct Answer is D
Explanation
Choice A reason:Asking the client why he thinks the pain isn’t from hiking may come across as dismissive and could heighten his anxiety. It does not address his concerns constructively or facilitate a medical evaluation to determine the cause of the pain.
Choice B reason:Reassuring the client that bone cancer is unlikely without a medical evaluation is inappropriate, as it may minimize his concerns and delay necessary assessment. The nurse should avoid making diagnostic assumptions without provider input.
Choice C reason:Suggesting genetic testing is premature without a medical evaluation to determine if the pain warrants such testing. The client’s pain is likely related to hiking, and a provider’s assessment should guide any further diagnostic steps.
Choice D reason:Explaining that a provider will evaluate the client and determine the next steps is the most appropriate action. This response validates the client’s concerns, ensures a professional assessment of the knee pain, and provides a clear path forward without making assumptions about the cause.
Correct Answer is D
Explanation
Choice A reason: SSRIs do not increase norepinephrine levels; that is the action of SNRIs or other antidepressant classes.
Choice B reason: SSRIs do not inhibit serotonin production; instead, they work by blocking reuptake, leading to increased serotonin availability.
Choice C reason: SSRIs do not lower dopamine levels; this would worsen mood symptoms rather than improve them.
Choice D reason: SSRIs block serotonin reuptake in presynaptic neurons, which increases serotonin availability in the synaptic cleft and helps elevate mood.
