To determine the blood types that are compatible with a patient who has B+ blood type, we need to consider the following rules of blood transfusion compatibility based on ABO and Rh blood group systems:

1. ABO Compatibility:
- Blood type B can donate to B and AB.
- Blood type B can receive from B and O.

2. Rh Compatibility:
- Rh+ can receive from Rh+ and Rh-.
- Rh+ cannot donate to Rh-.

Given the patient has B+ blood type:

- B and O Compatibility: Since the patient has B type blood, they can receive blood from donors with B and O type blood.
- Rh+ and Rh- Compatibility: Since the patient is Rh+, they can receive from both Rh+ and Rh- donors.

Combining these rules:

- The patient can receive blood from B+ and B- (B type can give to B and by Rh factor).
- The patient can also receive blood from O+ and O- (O type can give to any ABO group and by Rh factor).

Therefore, the compatible donor blood types for a patient with B+ blood type are:

- B+
- B-
- O+
- O-

So, the donor's blood type for a patient with B+ must be:

- B+
- B-
- O+
- O-
