Which of the following blood tests should be performed before a blood transfusion?
- A. Prothrombin and coagulation time
- B. Blood typing and cross-matching
- C. Bleeding and clotting time
- D. Complete blood count (CBC) and electrolyte levels
Correct Answer: B
Rationale: Before administering a blood transfusion, it is crucial to perform blood typing and cross-matching to ensure compatibility between the donor's blood and the recipient's blood. This process helps prevent adverse reactions such as transfusion reactions, which can be life-threatening. Prothrombin and coagulation time, bleeding and clotting time, as well as CBC and electrolyte levels are important tests in other clinical contexts, but for blood transfusions, blood typing and cross-matching are essential to ensure patient safety.
