A patient with bipolar disorder, mania, relapsed after discontinuing lithium. The health care provider prescribes lithium 600 mg BID and olanzapine (Zyprexa) 10 mg BID. What is the rationale for addition of olanzapine to the lithium regime? It will:

Correct Answer: B

Rationale: The correct answer is B: bring hyperactivity under rapid control. Olanzapine, an atypical antipsychotic, is commonly used in the acute treatment of mania due to its ability to rapidly control symptoms like hyperactivity. Lithium, on the other hand, is used for long-term mood stabilization in bipolar disorder. The addition of olanzapine helps address the acute manic symptoms while lithium works on the long-term management. Choices A and C are incorrect as olanzapine does not minimize lithium's side effects or potentiate its antimanic action. Choice D is incorrect as olanzapine is typically used for acute symptom management, not for long-term control of hyperactivity.

Correct Answer: A

Rationale: The correct answer is A: Reduced anxiety. GABA is an inhibitory neurotransmitter in the brain that helps reduce neuronal excitability. By potentiating its action, the medication would enhance its calming effect, resulting in reduced anxiety. Choice B (Enhanced memory) is incorrect as GABA primarily affects anxiety and not memory. Choice C (Disorganized thinking) is incorrect as GABA's role is not related to cognitive processes. Choice D (Sensory perceptual alterations) is incorrect as GABA modulation does not typically lead to changes in sensory perception.

Correct Answer: A

Rationale: The correct answer is A because it provides the patient with appropriate education on how to manage the dizziness related to orthostatic hypotension, a common side effect of antidepressants. Changing positions slowly and dangling feet can prevent sudden drops in blood pressure upon standing. Choice B is incorrect as stopping driving may not be necessary, and napping may not directly address the dizziness. Choice C is incorrect as it dismisses the patient's symptoms and does not provide practical advice on managing the dizziness. Choice D is incorrect as abruptly stopping the medication without consulting the doctor can be dangerous and does not address the underlying issue of orthostatic hypotension.

Correct Answer: D

Rationale: The correct answer is D: Nonopioid analgesic, such as indomethacin (Indocin). Given the ankle injury, nonopioid analgesics like indomethacin are appropriate for managing pain as they target inflammation and reduce pain without the risk of opioid-related side effects. Synthetic opioids (A) and opium alkaloids (B) are not typically indicated for mild to moderate pain like an ankle twist. Opioid antagonists (C) like naloxone are used to reverse opioid overdose, not for pain relief. In this case, the nonopioid analgesic is the most suitable choice for managing the player's pain effectively.

Correct Answer: C

Rationale: The correct answer is C: Salami and Swiss cheese sandwich. This is because salami and Swiss cheese are high in tyramine, which can cause a hypertensive crisis in patients taking MAOIs due to their inhibitory effect on monoamine oxidase. Orange juice (A) does not contain tyramine. Fried eggs over-easy (B) and biscuits with honey (D) are also safe choices as they do not contain high levels of tyramine. Therefore, the need for additional teaching is indicated by the selection of foods high in tyramine like salami and Swiss cheese.
