A patient receiving intravenous magnesium replacement becomes drowsy and has markedly reduced deep tendon reflexes. Which action has priority?
Correct answer: B. Stop or slow the infusion and assess respirations
- A. Continue the infusion and reassess in one hour
- B. Stop or slow the infusion and assess respirations
- C. Encourage oral fluids and apply a warm blanket
- D. Place the patient upright and offer a high-potassium meal
Explanation
Reduced reflexes and drowsiness can indicate magnesium toxicity, which may progress to respiratory depression. The infusion is stopped or slowed according to protocol, and breathing is assessed because airway and breathing take priority.

Blood transfusion content includes compatibility, cross matching, administration precautions and recognition of haemolytic, febrile and allergic reactions, distinct from ordinary IV fluid reactions.
