Final answer:
The primary concern for a Jehovah's Witness client is blood transfusion consent due to their religious prohibition against transfusions. While organ donation, dietary restrictions, and pain management are important, blood transfusion poses the most immediate concern.
Step-by-step explanation:
A client who is a Jehovah's Witness may have specific health care needs related to their beliefs. The concern that the nurse should have for planning care is a) Blood transfusion consent. Jehovah's Witnesses typically refuse blood transfusions due to their religious beliefs, which can impact medical care decisions, especially in situations where a transfusion might be considered a standard treatment. While discussing organ donation, dietary restrictions, or pain management options are also important aspects of holistic care, the most immediate and potentially life-threatening concern would often be the client's non-consent to blood transfusions.
Regarding organ transplants, blood relatives are often preferred as organ donors because they are more likely to be compatible, reducing the risk of rejection. The role of immunosuppression in transplantation is crucial, as it involves medication to dampen the recipient's immune response to avoid rejection of the new organ. However, this is not directly related to the specific care concerns for a Jehovah's Witness client.
