Final answer:
The nurse should inform the patient about the potential risks of refusing a blood transfusion, while respecting their religious beliefs.
Step-by-step explanation:
The nurse should respond with option (b) 'I respect your beliefs, but I must inform you that refusing a blood transfusion could have serious consequences for your health.'
It is important for the nurse to respect the patient's religious beliefs, but it is also their duty to inform the patient about the potential risks associated with refusing a blood transfusion. The nurse should explain that a ruptured appendix can lead to severe bleeding and a blood transfusion may be necessary to save the patient's life.
The nurse can also offer to arrange a visit from a spiritual advisor to help the patient make a decision about their care, as mentioned in option (c).
