On the basis of current knowledge of neurotransmitter effects, a nurse anticipates that the treatment plan for a patient with memory difficulties may include medications designed to do what?
Decrease dopamine at receptor sites
Inhibit GABA production
Prevent destruction of acetylcholine
Increase dopamine sensitivity
The Correct Answer is C
Choice A reason: Decreasing dopamine is used for disorders like schizophrenia, where excess mesolimbic dopamine causes hallucinations. Memory difficulties, often linked to Alzheimer’s, involve cholinergic deficits, not dopamine excess. Reducing dopamine could worsen cognition by disrupting reward and attention pathways, making this approach scientifically inappropriate for memory issues.
Choice B reason: Inhibiting GABA production is irrelevant for memory. GABA regulates neural inhibition, and its reduction could increase excitability, worsening conditions like seizures. Memory deficits, particularly in dementia, stem from reduced acetylcholine in the hippocampus, not GABA, making this option misaligned with the neurobiology of memory impairment.
Choice C reason: Preventing acetylcholine destruction, via cholinesterase inhibitors, enhances cholinergic activity in the hippocampus and cortex, critical for memory in conditions like Alzheimer’s. Low acetylcholine levels impair neural signaling, causing memory deficits. This approach directly addresses the neurochemical basis of memory difficulties, making it scientifically appropriate for treatment.
Choice D reason: Increasing dopamine sensitivity is relevant for disorders like Parkinson’s, not memory deficits. Dopamine affects motivation and movement, not memory, which relies on acetylcholine in the hippocampus. Enhancing dopamine could disrupt cognitive balance, worsening memory without addressing the cholinergic deficits central to memory impairment.

Correct Answer is B
Explanation
Choice A reason: Active suicidality, linked to severe serotonin deficits, requires inpatient hospitalization for constant monitoring to ensure safety. Partial hospitalization is insufficient for acute risk, as it lacks 24-hour supervision, making this patient inappropriate for this less intensive care setting.
Choice B reason: Agoraphobia and panic episodes, driven by norepinephrine surges, benefit from partial hospitalization’s structured psychoeducation and therapy. Relaxation techniques reduce amygdala hyperactivity, supporting outpatient management with daily support, making this patient suitable for partial hospitalization’s intensive, non-residential treatment.
Choice C reason: Stable lithium levels indicate controlled bipolar disorder, not requiring partial hospitalization. Regular follow-up manages neurotransmitter balance, suitable for outpatient care. Partial hospitalization is for active symptoms, not stable patients, making this an incorrect referral choice.
Choice D reason: Alcohol use concerns suggest outpatient substance abuse programs, not partial hospitalization. While dopamine reward pathways are involved, partial hospitalization targets acute psychiatric symptoms, not substance issues alone, making this patient unsuitable for this level of care.
Correct Answer is A
Explanation
Choice A reason: Interventions, like offering snacks, address identified problems (e.g., forgetting to eat) to meet nutritional needs. This action targets physiological deficits, potentially linked to cognitive impairments from low acetylcholine in dementia, ensuring adequate caloric intake to support brain function and overall health in the care plan.
Choice B reason: Planning/goals outline desired outcomes, not specific actions. Forgetting to eat, possibly due to frontal lobe dysfunction, requires goals like “maintain adequate nutrition.” Interventions, not goals, specify actions like offering snacks, making this section incorrect for the statement’s placement in the care plan.
Choice C reason: Assessment involves data collection, like observing eating patterns, not actions like offering snacks. Forgetting to eat may reflect cognitive deficits, but assessment identifies the problem, not solutions. This section precedes interventions, making it an incorrect location for the described statement.
Choice D reason: Diagnosis identifies problems, like “impaired nutrition” due to cognitive deficits, not specific actions. Offering snacks is an intervention to address the diagnosis, not the diagnosis itself. This section is incorrect for the statement, which belongs in the intervention phase of the care plan.
