What should be considered when assessing the effectiveness of the dosage of Valium a patient has been receiving for six months?

Correct Answer: A

Rationale: The correct answer is A: Potential for tolerance/dependence exists - doses may need to be increased. When assessing the effectiveness of Valium dosage, it's crucial to consider tolerance and dependence because long-term use can lead to reduced efficacy, necessitating dose adjustments. This is important for ensuring the patient receives the optimal therapeutic benefit. Gastrointestinal disturbances (B) and sexual dysfunction (C) are potential side effects of Valium but are not directly related to assessing dosage effectiveness. Selective serotonin reuptake inhibitors (D) are a different class of medications and not relevant to evaluating Valium dosage.

Correct Answer: A

Rationale: The correct answer is A because tricyclic antidepressants have numerous side effects such as dry mouth, constipation, weight gain, and sedation. These side effects can be intolerable for patients, leading to poor adherence. Choices B, C, and D are incorrect because while tricyclic antidepressants can have interactions with other medications, cause cardiac problems, and be lethal in overdose, these factors alone do not fully explain why they are infrequently used compared to other antidepressant options. The primary reason for their limited use lies in their significant side effect profile.

Correct Answer: A

Rationale: The correct answer is A: Monoamine oxidase inhibitors (MAOIs). MAOIs work by inhibiting the enzyme monoamine oxidase, which is responsible for breaking down serotonin and norepinephrine. By inhibiting this enzyme, MAOIs increase the availability of serotonin and norepinephrine in the brain, leading to improved mood. Incorrect choices: B: Explosive occipital headache - This choice is irrelevant to the question and does not relate to antidepressants or neurotransmitter availability. C: Polyuria - This choice is a symptom related to excessive urination and does not pertain to antidepressants or neurotransmitter metabolism. D: Selective serotonin reuptake inhibitors (SSRIs) - While SSRIs also increase serotonin levels, they do so by blocking the reuptake of serotonin, not by inhibiting enzymes that metabolize serotonin and norepinephrine.

Correct Answer: A

Rationale: The correct answer is A: GI upset. Divalproex is known to cause gastrointestinal (GI) upset as a common side effect, including symptoms like nausea, vomiting, and diarrhea. This is due to its irritant effect on the stomach lining. B: Headache - While headache can be a side effect of some medications, it is not a common side effect of Divalproex. C: Dizziness - Dizziness can occur as a side effect of Divalproex, but it is less common compared to GI upset. D: Weight gain - Weight gain is a known side effect of Divalproex, but it is not as common as GI upset. Weight gain typically occurs over time with long-term use.
