Question 9
Regular
A nurse should assess a patient taking a medication with anticholinergic properties for inhibition of what function?
Correct!
Incorrect
The correct answer is: A
Rationale
A nurse should assess a patient taking a medication with anticholinergic properties for inhibition of the parasympathetic nervous system. Anticholinergic medications block acetylcholine, leading to reduced parasympathetic activity which can affect bodily functions such as digestion, heart rate, and salivation, thus requiring careful monitoring of the patient’s responses and symptoms related to these functions.
B: Sympathetic nervous system Anticholinergic medications specifically target the parasympathetic nervous system, leaving the sympathetic nervous system largely unaffected. This distinction is crucial in understanding their pharmacological action and effects.
C: Reticular activating system The reticular activating system is primarily involved in regulating wakefulness and sleep cycles, not directly influenced by anticholinergic medications. Their action focuses on autonomic functions rather than arousal mechanisms.
D: Medulla oblongata The medulla oblongata controls vital autonomic functions such as breathing and heart rate. Anticholinergic effects primarily influence peripheral parasympathetic responses rather than central autonomic centers like the medulla oblongata.

Question 10
Regular
The therapeutic action of monoamine oxidase inhibitors (MAOIs) blocks neurotransmitter reuptake, causing what effect?
Correct!
Incorrect
The correct answer is: A
Rationale
Increased concentration of neurotransmitters in the synaptic gap.
Monoamine oxidase inhibitors (MAOIs) prevent the breakdown of neurotransmitters, leading to their accumulation in the synaptic gap. This elevated concentration enhances neurotransmission, contributing to improved mood and cognitive function, which is the desired therapeutic effect of these medications.
B: Decreased concentration of neurotransmitters in serum. This option contradicts the MAOIs' function, as they lead to increased, not decreased, levels of neurotransmitters, thus misrepresenting their therapeutic action.
C: Destruction of receptor sites. This choice misinterprets the mechanism of MAOIs, as they do not destroy receptor sites; rather, they influence neurotransmitter levels without directly affecting receptor integrity.
D: Limbic system stimulation. While MAOIs affect mood, this option inaccurately suggests direct stimulation of specific brain regions, ignoring the broader impact on neurotransmitter availability and overall synaptic activity.

Question 22
Regular
A patient's partner, who is a chemist, asks a nurse how serotonin reuptake inhibitors (SSRIs) lift depression. What response will the nurse provide?
Correct!
Incorrect
The correct answer is: B
Rationale
SSRIs make more serotonin available at the synaptic gap. This mechanism enhances serotonin levels in the brain, effectively alleviating depressive symptoms by improving neurotransmitter signaling and promoting mood elevation.
A: Destroys increased amounts of neurotransmitters. SSRIs do not destroy neurotransmitters; instead, they inhibit their reuptake, allowing for prolonged action and availability at the synaptic junction.
C: Increases production of acetylcholine and dopamine. SSRIs specifically target serotonin reuptake and do not directly influence the production of acetylcholine or dopamine in the brain.
D: Blocks muscarinic and ?┬▒??-norepinephrine receptors. SSRIs primarily focus on serotonin reuptake inhibition and do not block muscarinic or norepinephrine receptors, which are involved in different pharmacological pathways.

Question 23
Regular
A patient has taken many conventional antipsychotic drugs over the years. The health care provider, who is concerned about early signs of tardive dyskinesia, prescribes risperidone. A nurse planning care for this patient understands what fact about second-generation antipsychotics?
Correct!
Incorrect
The correct answer is: D
Rationale
Second-generation antipsychotics produce fewer motor side effects. This characteristic makes them particularly suitable for patients at risk for tardive dyskinesia, as they minimize the potential for exacerbating these adverse effects.
A: They are less costly. Cost does not define the efficacy or safety profile of second-generation antipsychotics, which are often more expensive than conventional options yet provide essential therapeutic benefits.
B: They have a higher potency. Second-generation antipsychotics are typically considered to have lower potency compared to some first-generation drugs, which may lead to fewer side effects rather than higher effectiveness.
C: They are more readily available. Availability can vary by region and specific formulations, so it cannot be assumed that second-generation antipsychotics are universally more accessible than their conventional counterparts.

Question 24
Regular
The laboratory report for a patient taking clozapine indicates the patient is experiencing agranulocytosis. The nurse should implement which intervention first?
Correct!
Incorrect
The correct answer is: A
Rationale
Report the laboratory results to the health care provider.
Prompt reporting of agranulocytosis is crucial, as it poses a significant risk for serious infection. The health care provider must be informed immediately to adjust treatment plans and ensure patient safety effectively.
B: Give the next dose of the medication as prescribed. Administering clozapine during agranulocytosis can exacerbate the condition, increasing the risk of complications rather than addressing the urgent need for medical intervention.
C: Administer aspirin and force fluids. Aspirin does not address the underlying issue of agranulocytosis and could lead to further complications, while force fluids alone cannot mitigate the immediate health risks involved.
D: Repeat the laboratory tests. Repeating tests delays critical intervention and does not address the urgency of the situation; immediate action is required based on existing lab results indicating agranulocytosis.
Correct Answer: A

Question 25
Regular
A nurse administering psychotropic medications should be prepared to intervene when giving a drug that blocks the attachment of norepinephrine to ?┬▒??-receptors because the patient may experience what effect?
Correct!
Incorrect
The correct answer is: C
Rationale
C: Orthostatic hypotension can occur when norepinephrine attachment to α-receptors is blocked, leading to reduced vascular tone and impaired blood pressure regulation, causing dizziness or fainting upon standing.
A: Increased psychotic symptoms might arise from other factors but are not directly linked to blocking norepinephrine at α-receptors, which primarily affects blood pressure rather than psychosis.
B: Severe appetite disturbance could be a side effect of different psychotropic medications but is not specifically associated with blocking norepinephrine's attachment to α-receptors, which primarily influences cardiovascular functions.
D: Hypertensive crisis is typically related to excessive norepinephrine activity, not blocking its attachment to α-receptors, which would lead to decreased blood pressure rather than an acute hypertensive episode.

Question 26
Multiple Choice
A nurse prepares to administer an antipsychotic medication to a patient diagnosed with schizophrenia. Additional monitoring of the medication's effects and side effects will be most important if the patient is also diagnosed with which health problem? (Select all that apply.)
Correct!
Incorrect
The correct answer is: A,D,E
Rationale
A: Parkinson disease, D: Epilepsy, E: Diabetes. Monitoring is critical for these conditions as antipsychotic medications can exacerbate movement disorders, increase seizure risk, or affect glucose metabolism, leading to severe health complications in affected patients.
B: Graves' disease. This condition primarily affects thyroid function and metabolism, showing no direct correlation with the effects or side effects of antipsychotic medications requiring additional monitoring.
C: Osteoarthritis. While this condition causes joint pain and mobility issues, it does not interact significantly with antipsychotic medications, thus not necessitating enhanced monitoring of their effects or side effects.

Question 27
Multiple Choice
The spouse of a patient diagnosed with schizophrenia asks, 'Which neurotransmitters are more active when a person has schizophrenia?' The nurse's response will focus on which neurotransmitters? (Select all that apply.)
Correct!
Incorrect
The correct answer is: D,E
Rationale
Dopamine and norepinephrine are more active when a person has schizophrenia. Elevated levels of these neurotransmitters contribute significantly to the symptoms associated with the disorder, particularly psychosis and mood disturbances.
A: GABA Reduced GABA activity is often linked to schizophrenia, but it does not represent increased activity. Thus, it plays a different role than the neurotransmitters mentioned in the context.
B: Substance P This neurotransmitter is involved in pain perception and has limited direct association with schizophrenia. Its activity does not align with the primary neurotransmitter changes observed in this condition.
C: Histamine While histamine is involved in various brain functions, it does not exhibit increased activity in schizophrenia. Its role is less relevant compared to dopamine and norepinephrine in this context.

Question 28
Multiple Choice
An individual is experiencing problems associated with memory. Which cerebral structures are most likely to be involved in this deficit? (Select all that apply.)
Correct!
Incorrect
The correct answer is: A,C,D
Rationale
The prefrontal cortex, temporal lobe, and parietal lobe are most likely involved in memory deficits. These structures play crucial roles in processing, storing, and retrieving memories, essential for cognitive function.
B: Occipital lobe Primarily associated with visual processing, the occipital lobe does not directly contribute to memory functions, making it less relevant in this context of memory issues.
E: Basal ganglia While the basal ganglia are important for motor control and procedural learning, they do not directly govern memory processes, limiting their involvement in memory deficits.
