Final answer:
The nurse should instruct the client to avoid crowds and individuals with infections to reduce the risk of exposure to harmful pathogens.
Step-by-step explanation:
The nurse should plan to include the instruction to avoid crowds and individuals with infections in the discharge teaching for the client receiving chemotherapy and experiencing bone marrow suppression. This is because bone marrow suppression can lead to a weakened immune system, making the client more susceptible to infections. Avoiding crowds and individuals with infections can help reduce the risk of exposure to harmful pathogens.
