Question 1

Newer or &#34;atypical&#34; antipsychotics are often preferred because:&#10;A)they bind more effectively to dopamine receptors in the basal ganglia.&#10;B)they offer a greater chance of curing schizophrenia.&#10;C)they are less expensive than traditional agents.&#10;D)they have a reduced risk of causing motor side effects.&#10;E)they are available without prescription.

Accepted Answer

Atypical antipsychotics have a reduced risk of causing motor side effects, such as tardive dyskinesia, compared to traditional agents.

Question 2

Antipsychotic drugs can result in the production of abnormal movement patterns known as:&#10;A)intra-articular symptoms.&#10;B)extrapyramidal symptoms.&#10;C)spinocerebellar symptoms.&#10;D)dorsal column symptoms.&#10;E)malignant hyperthermia.

Accepted Answer

Antipsychotic drugs can result in extrapyramidal symptoms, which are abnormal movement patterns such as muscle stiffness, tremors, and involuntary muscle movements. It is important to monitor for these symptoms and adjust treatment as necessary to minimize their impact on the patient's quality of life.

Question 3

Tardive dyskinesia is often the most feared motor side effect of antipsychotic drugs because:&#10;A)it is associated with muscle atrophy.&#10;B)it is associated with osteoporosis.&#10;C)it can cause cardiac dysrhythmias.&#10;D)it can cause peripheral neuropathies.&#10;E)it may be irreversible.

Accepted Answer

Tardive dyskinesia is often irreversible, which means that the symptoms may persist even after the antipsychotic medication is discontinued. This can be a major concern for patients and healthcare providers, as it can significantly impact quality of life.

Question 4

Patients taking relatively high doses of the more potent antipsychotics may experience catatonia,stupor,rigidity,tremors,and fever.These symptoms comprise a serious disorder known as:&#10;A)Horner' syndrome.&#10;B)Brown-Sequard syndrome.&#10;C)Charcot' syndrome.&#10;D)neuroleptic malignant syndrome.&#10;E)general adaptation syndrome.

Accepted Answer

The symptoms listed, including catatonia, stupor, rigidity, tremors, and fever, are all indicative of neuroleptic malignant syndrome (NMS), a serious and potentially fatal disorder that can occur in patients taking high doses of potent antipsychotics. Treatment for NMS includes discontinuing the antipsychotic medication and providing supportive care.

Question 5

Schizophrenia appears to be caused primarily by an overactivity of _______ pathways in certain parts of the brain,such as the limbic system.&#10;A)dopamine&#10;B)acetylcholine&#10;C)norepinephrine&#10;D)5-hydroxytryptamine (serotonin)&#10;E)gama-amino butyric acid (GABA)

Accepted Answer

Although all of the neurotransmitters listed have been implicated in schizophrenia, the overactivity of dopamine pathways in certain parts of the brain is currently believed to be the primary cause of the disorder.

Question 6

Antipsychotics are often used in Alzheimer disease and other cases of dementia:&#10;A)to improve cognition and memory.&#10;B)to improve balance.&#10;C)to help control aggression and agitation.&#10;D)to increase vomiting and diarrhea.&#10;E)none of the above

Accepted Answer

Antipsychotics are often used in Alzheimer's disease and other cases of dementia to help control aggression and agitation. They can be effective in reducing symptoms of agitation, delusions, and hallucinations but should be used with caution due to their potential for side effects.

Question 7

Antipsychotic drugs are _____ receptor ______.&#10;A)dopamine;agonists&#10;B)dopamine;antagonists&#10;C)acetylcholine;agonists&#10;D)acetylcholine;antagonists&#10;E)5-hydroxytryptamine;agonists

Accepted Answer

Antipsychotic drugs are dopamine receptor antagonists, meaning they block the action of dopamine in the brain. This is why they are often used to treat conditions such as schizophrenia, which is characterized by an overactive dopamine system.

Question 8

All of the following motor side effects are associated with antipsychotic drugs EXCEPT:&#10;A)spasticity.&#10;B)tardive dyskinesia.&#10;C)pseudoparkinsonism.&#10;D)akathisia.&#10;E)dystonia.

Accepted Answer

Spasticity is not typically associated with antipsychotic drugs. The other motor side effects listed are commonly seen with these medications.
