A patient receives a large volume of blood products and develops tingling around the mouth, muscle twitching and a prolonged QT interval. Which complication should the nurse suspect?
Correct answer: A. Citrate-related hypocalcaemia
- A. Citrate-related hypocalcaemia
- B. Acute hypernatremia
- C. Transfusion-associated hyperkalaemia
- D. Dilutional hypermagnesemia
Explanation
Citrate used to preserve blood binds ionised calcium, and rapid or massive transfusion can produce hypocalcaemia. Perioral tingling, muscle twitching and QT prolongation are important signs requiring prompt reporting and monitoring.

About IV Fluids and Blood Transfusion
IV therapy covers crystalloid and colloid fluids, electrolyte replacement, maintenance and resuscitation fluids, infusion equipment and complications such as infiltration, phlebitis, fluid overload and electrolyte imbalance. Blood transfusion content includes compatibility, cross matching, administration precautions and recognition of haemolytic, febrile and allergic reactions, distinct from ordinary IV fluid reactions.
