During an initial assessment interview, the client reports using an herbal product to help manage his depression after his recent heart attack. The nurse demonstrates an understanding of the greatest risk of injury these circumstances pose to the client when asking:

Correct Answer: B

Rationale: Rationale for Correct Answer (B): - The correct answer is B because the greatest risk of injury in this scenario is potential bleeding complications due to the use of herbal products. - Herbal products can interact with medications, including anticoagulants, increasing the risk of bleeding. - Asking about difficulty stopping bleeding helps assess for potential adverse effects of the herbal product on clotting factors. - This question directly addresses a specific risk associated with herbal product use in the context of a recent heart attack. Summary of Incorrect Choices: - Choice A is incorrect because while quality control issues may be a concern with herbal products, it is not the most immediate risk in this case. - Choice C is incorrect as it focuses on the source of the recommendation rather than the client's health risks. - Choice D is incorrect as it does not address the potential physical harm related to herbal product use after a heart attack.

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: Block manifestations: Tremors. Beta blockers and alpha-2 receptor agonists are used in patients with anxiety to block physical manifestations such as tremors. Beta blockers reduce the physical symptoms of anxiety by blocking the effects of adrenaline on the body, including tremors. Alpha-2 receptor agonists also help reduce physical symptoms by decreasing the release of norepinephrine. Palpitations (B), tachycardia (C), and sweating (D) are also physical symptoms of anxiety, but beta blockers and alpha-2 receptor agonists primarily target tremors in this context.

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.
