After teaching a group of nursing students about the neurobiologic theories of depression, the instructor determines the need for additional teaching when the students identify which neurotransmitter as playing a role?

Correct Answer: A

Rationale: The correct answer is A: Gamma-amino butyric acid (GABA). GABA is not typically associated with the neurobiologic theories of depression. Norepinephrine, serotonin, and dopamine are neurotransmitters commonly implicated in depression. GABA is known for its role in anxiety disorders, not depression. Therefore, the need for additional teaching is identified when students select GABA as playing a role in depression.

Correct Answer: B

Rationale: The correct answer is B because gender identity disorders involve distress related to the individual's assigned sex. This is a key characteristic as individuals with this disorder experience a strong and persistent discomfort with their biological sex. Choice A is incorrect as it refers to sexual orientation rather than gender identity. Choice C is incorrect as it describes a different disorder called paraphilic disorders. Choice D is incorrect as it pertains to sexual dysfunctions rather than gender identity disorders. Therefore, the instructor would include discomfort about one's assigned sex when discussing gender identity disorders to accurately educate the students.

Correct Answer: B

Rationale: The correct answer is B: Ineffective Health Maintenance related to homelessness. This is the priority nursing diagnosis because the client's foot infection needs immediate attention to prevent complications. Ineffective Health Maintenance addresses the client's inability to manage health and seek medical care, which is crucial in this case. A: Social Isolation is not the priority as the client is receiving regular care and interaction in the mobile clinic. C: Chronic Low Self-Esteem may be a concern but is not as urgent as addressing the foot infection. D: Imbalanced Nutrition is not directly related to the client's current issue of a foot infection.

Correct Answer: B

Rationale: The correct answer is B: Prescribe psychotropic medication. Advanced practice nurses, such as psychiatric nurse practitioners, have prescriptive authority to prescribe medications in psychiatric settings. This intervention requires advanced knowledge and specialized training. Conducting mental health assessments (A) and establishing therapeutic relationships (C) are within the scope of practice for staff nurses and do not require advanced practice credentials. Individualizing nursing care plans (D) is also a standard nursing practice that does not necessarily require advanced practice training. In summary, prescribing psychotropic medication is the additional intervention that an advanced practice nurse would perform in a psychiatric unit, distinguishing their role from that of a staff nurse.

Correct Answer: B

Rationale: The correct answer is B: Rice with black beans. This choice is correct because it is a high-fiber, plant-based meal that is low in protein, which is important for a client with hepatic encephalopathy. Rice and black beans provide complex carbohydrates and fiber, aiding in ammonia detoxification without increasing protein intake. The other choices are incorrect because: A: A sandwich and milkshake are high in protein and may exacerbate hepatic encephalopathy. C: Cottage cheese and tuna lettuce are high in protein, which can lead to increased ammonia production. D: Three-egg omelette with low-sodium ham is high in protein, which is not recommended for clients with hepatic encephalopathy.
