Question:
A patient with Hb 7 was to be transfused with 2 packs of blood. The first pack was transfused in 2 hours after which vitals were stable and then the transfusion of the next pack was staed . But suddenly the patient develops breathlessness and hypeension. What can be the cause of this sudden reaction?

Options:
A. transfusion related circulatory overload (TACO)
B. allergic reaction to transfused blood
C. transfusion related acute lung injury (TRALI)
D. transfusion related acute renal failure'

[2025-10-02T00:39:05.546638] [PI reasoning] **Assessing transfusion reactions**

I'm working through a multiple-choice question regarding a patient who received a blood transfusion. After the first unit, everything was stable, but after starting the second unit, the patient developed breathlessness and hypertension. This points to TACO, which matches the symptom profile: dyspnea and high blood pressure due to volume overload, especially in vulnerable patients. TRALI could also be a consideration, but it usually presents with hypotension. Allergic reactions present differently, so they’re less likely here.
