A postpartum client who is actively breastfeeding is scheduled for therapeutic sodium iodide I 131. Which action is the priority?
1Stop and clarify I 131 because lactation is contraindicated and a feeding plan is required.✓ Correct answer
2Proceed after one feeding and discard expressed milk only until the next routine clinic visit.
3Administer the dose immediately after breastfeeding to limit radioiodine exposure to the infant.
4Place radiation shielding around the breast pump and continue the usual feeding schedule.
Explanation
Therapeutic sodium iodide I 131 is contraindicated during lactation; breastfeeding cessation and postpartum restrictions require advance counseling and a clear alternative feeding plan.
Quick answer Prevent radioiodine exposure through lactation.
Why this is correct The label requires breastfeeding or pumping cessation before therapy and states breastfeeding must not resume for the remainder of the postpartum period after administration.
Easy analogy or mental picture Think of medication safety as a control panel: identify the dangerous signal, change the correct control, and verify the response.
Memory hook Cue, action, response, reassessment.
NCLEX decision rule Choose the action that prevents the most immediate medication-related harm while preserving the continuing indication.
Why the other choices are wrong Options that delay escalation, ignore a contraindication, or change therapy without authorization do not close the safety loop.
