Which of the following best describes dystonia?
Restlessness and unable to sit still.
Muscle spasms on the face, eyes, neck, and tongue.
Tongue rolling and lip smacking.
Tremors at rest, bradykinesia, and shuffling gait.
The Correct Answer is B
A. Restlessness and unable to sit still. This describes akathisia, a movement disorder characterized by an intense feeling of restlessness, often seen as a side effect of antipsychotic medications.
B. Muscle spasms on the face, eyes, neck, and tongue. Dystonia is characterized by sudden, involuntary muscle contractions, often affecting the face, neck (torticollis), eyes (oculogyric crisis), tongue, and jaw. It is a common extrapyramidal side effect (EPS) of antipsychotic medications, particularly first-generation antipsychotics.
C. Tongue rolling and lip smacking. These are hallmark symptoms of tardive dyskinesia, a late-onset movement disorder caused by long-term use of dopamine-blocking agents. It involves involuntary, repetitive movements of the mouth, face, and limbs.
D. Tremors at rest, bradykinesia, and shuffling gait. These symptoms are characteristic of Parkinsonism, an extrapyramidal side effect of dopamine-blocking medications. It mimics Parkinson’s disease and includes rigidity, tremors, and slow movements.

Correct Answer is C
Explanation
A. Lurasidone (Latuda) is a second-generation (atypical) antipsychotic, not a third-generation antipsychotic. It primarily blocks dopamine (D2) and serotonin (5-HT2A) receptors and is used to treat schizophrenia and bipolar depression.
B. Cariprazine (Vraylar) is a third-generation antipsychotic, functioning as a partial dopamine (D2/D3) and serotonin (5-HT1A) receptor agonist. It is used for schizophrenia, bipolar disorder, and major depressive disorder (MDD) adjunctive treatment.
C. Haloperidol (Haldol) is a first-generation (typical) antipsychotic, not a third-generation antipsychotic. It works by strongly blocking D2 receptors, leading to a high risk of extrapyramidal symptoms (EPS) but lower metabolic side effects compared to atypical antipsychotics.
D. Aripiprazole (Abilify) is a third-generation antipsychotic, known for its partial dopamine (D2) agonist properties. It has a lower risk of EPS and metabolic side effects compared to second-generation antipsychotics and is used for schizophrenia, bipolar disorder, and adjunctive treatment in depression.
Correct Answer is C
Explanation
A. Meaningless rhythm of words. This describes word salad, a disorganized speech pattern where words are strung together without logical connection, often seen in schizophrenia or severe psychosis.
B. Roundabout. This refers to circumstantial speech, where an individual provides excessive, unnecessary details before eventually arriving at the main point. This is commonly seen in mania, obsessive-compulsive disorder (OCD), or cognitive impairment.
C. Made-up words. Neologisms are newly invented words or phrases that have no meaning to others but may carry personal significance to the individual. This is frequently observed in schizophrenia, psychotic disorders, or neurological conditions like aphasia.
D. Repeating of another's words. This describes echolalia, a speech disturbance where a person repeats words or phrases spoken by others, often seen in autism spectrum disorder (ASD), schizophrenia, or catatonia.
