All of the following are second generation antipsychotics except
haloperidol (Haldol)
ziprasidone (Geodon)
risperidone (Risperdal)
olanzapine (Zyprexa)
The Correct Answer is A
A. Haloperidol (Haldol) is a first-generation (typical) antipsychotic that primarily blocks dopamine (D2) receptors. It is associated with a higher risk of extrapyramidal side effects (EPS), including dystonia, akathisia, and tardive dyskinesia, compared to second-generation antipsychotics.
B. Ziprasidone (Geodon) is a second-generation (atypical) antipsychotic that blocks both dopamine (D2) and serotonin (5-HT2A) receptors. It has a lower risk of EPS but can cause QT prolongation, requiring ECG monitoring in patients with cardiac conditions.
C. Risperidone (Risperdal) is a second-generation antipsychotic with dopamine and serotonin antagonism. It is effective for schizophrenia, bipolar disorder, and irritability in autism but has a higher likelihood of prolactin elevation and EPS at higher doses.
D. Olanzapine (Zyprexa) is a second-generation antipsychotic known for its high risk of metabolic side effects, including weight gain, diabetes, and dyslipidemia. It has a lower risk of EPS compared to first-generation antipsychotics.

Correct Answer is B
Explanation
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. Nagasaki Anxiety Scale. There is no recognized Nagasaki Anxiety Scale used in clinical practice for diagnosing anxiety disorders.
B. Vanderbilt Anxiety Scale. The Vanderbilt Assessment Scale is primarily used for ADHD screening in children, not for anxiety disorders. It evaluates symptoms of inattention, hyperactivity, and impulsivity, along with comorbid behavioral issues.
C. Hamilton Anxiety Scale. The Hamilton Anxiety Rating Scale (HAM-A) is a widely used diagnostic tool for assessing the severity of anxiety symptoms. It evaluates somatic and psychological symptoms of anxiety, such as tension, fears, insomnia, and autonomic disturbances. It is commonly used in clinical and research settings to monitor treatment response.
D. Jarrad and Cesar Anxiety Scale. There is no known Jarrad and Cesar Anxiety Scale in psychological or psychiatric diagnostic testing, making it an invalid option for anxiety assessment.
