Final answer:
The client's belief that their internal organs have turned to stone is a somatic delusion, which is a subtype of delusions commonly seen in schizophrenia where the person believes something abnormal is happening to their body.
Step-by-step explanation:
The client's statement 'my internal organs have turned to stone' is an example of a somatic delusion. This is a type of delusion where a person has an unfounded belief that something highly abnormal is happening to their body. In the context of schizophrenia, this might manifest as a belief that one's internal organs are turning into something else, as is the case with this client.
It's important to note that this kind of delusion differs from others such as persecutory delusions (where a person believes that others are plotting against them), grandiose delusions (where a person believes they hold special power or importance), or referential delusions (where a person believes that ordinary events or people carry special personal significance).
