Final answer:
The nurse should leave the client's room and return later in the day.
Step-by-step explanation:
The nurse should choose option d. Leave their clients room and return later in the day.
When a client with newly diagnosed type 1 diabetes mellitus (DM) reacts negatively to learning self-administration of insulin injections, it is important for the nurse to respect the client's wishes. The client may be feeling overwhelmed or anxious about the diagnosis and may need some time alone to process the information.
The nurse should leave the client's room and return later in the day to continue the teaching when the client is more receptive. It is crucial to establish a trusting and supportive relationship with the client, addressing their concerns and fears about insulin injections, and ensuring they understand the importance of insulin as a lifesaving drug for managing their condition.
