A 3-year-old child ingested approximately 20 tablets of iron that were prescribed to the child's mother. The medication that the nurse will prepare to reverse iron is:
 
  1. fomepizole (Antizol).
  2. pyridoxine (vitamin B6).
  3. deferoxamine (Desferal).
  4. sodium bicarbonate.

Question 2

A client is diagnosed with acute poisoning of acetylsalicylic acid (aspirin). The nurse knows that ion trapping will be the therapy of choice for this medication and prepares to:
 
  1. Insert a nasogastric tube for lavage.
  2. Provide supportive therapy.
  3. Hang a bag of 100 mL normal saline solution with 100 units regular insulin adjusted to the client's rising blood glucose levels.
  4. Administer sodium bicarbonate and furosemide (Lasix) intravenously.

Answer to Question 1

Correct Answer: 3
Rationale 1: Fomepizole (Antizol) is not the antidote for iron overdose.
Rationale 2: Pyridoxine (vitamin B6) is not the antidote for iron overdose.
Rationale 3: Deferoxamine (Desferal) is the antidote for iron overdose.
Rationale 4: Sodium bicarbonate is not the antidote for iron overdose.
Global Rationale: Deferoxamine (Desferal) is the antidote for iron overdose. The remaining drugs do not have this indication.

Answer to Question 2

Correct Answer: 4
Rationale 1: This procedure is not used in ion trapping.
Rationale 2: Supportive therapy is not a part of ion trapping.
Rationale 3: This treatment would be used for hypoglycemia, not for ion trapping.
Rationale 4: Forced alkaline diuresis may be used to increase the excretion of acidic drugs like salicylates. A diuretic such as furosemide along with IV sodium bicarbonate makes the urine more alkaline.
Global Rationale: Forced alkaline diuresis may be used to increase the excretion of acidic drugs like salicylates. A diuretic such as furosemide along with IV sodium bicarbonate makes the urine more alkaline. The remaining procedures are not part of ion trapping.
