Extract:


Question 1 of 5

The child with iron poisoning is given IV deferoxamine mesylate (Desferal). Following administration, the child suffers hypotension, facial flushing, and urticaria. The initial nursing intervention would be to:

Correct Answer: B

Rationale: The IV line should not be discontinued because other IV medications will be needed. Stop the medication and begin a normal saline infusion. The child is exhibiting signs of an allergic reaction and could go into shock if the medication is not stopped. The line should be kept opened for other medication. Taking vital signs and reporting to the physician is not an adequate intervention because the IV medication continues to flow. Assessing urinary output and, if it is 30 mL an hour, maintaining current treatment is an inappropriate intervention owing to the child's obvious allergic reaction.
