Final answer:
The behavior of 'standing on one foot for 15 minutes' is consistent with catatonic schizophrenia, which is characterized by abnormal motor behavior such as immobility or peculiar movements.
Step-by-step explanation:
Behavior consistent with catatonic schizophrenia includes marked motor abnormalities such as staying in a single posture for a long time, which is a sign of the disorder. The behavior described in the option c. Stands on one foot for 15 minutes is characteristic of catatonic schizophrenia. This condition can show up as immobility, excessive motor activity that is not influenced by external stimuli, extreme negativism or mutism, peculiar movements, echolalia, or echopraxia. The other options provided, such as talking excitedly, being suspicious of staff, or having delusions about an animal, might be relevant to other types of schizophrenia but do not specifically point to catatonia. Neuroleptic drugs are typically prescribed for schizophrenia, which help in reducing agitation, aggression, and symptoms such as hallucinations and delusions. These drugs can also facilitate more responsive and communicative behavior in withdrawn patients.
