When the nurse addresses questions to an adult client who is depressed, the client's responses are delayed. Which intervention should the nurse include in the client's plan of care?

A. Involving the client in a daily exercise program may be beneficial for depression but does not directly address the issue of delayed responses during questioning. B. Asking the client to describe her depression may be helpful for assessment purposes but does not address the immediate need of dealing with delayed responses. C. Spending time sitting in silence with the client allows the nurse to provide a supportive presence without pressure for immediate responses, which can be helpful for a client experiencing depression-related delays in communication. D. Observing for signs of possible psychosis is important but may not be indicated solely based on delayed responses; other symptoms would need to be present to warrant this concern.
