Which technique helps minimize systemic absorption when administering ophthalmic drops to a child?

• A. Apply pressure to the lacrimal punctum for 1 minute after administration
• B. Immediately rub the eyes after instillation
• C. Have the child look upward and keep eyes open for 5 minutes
• D. Wipe watery discharge with a tissue

Answer: (A)

The technique to minimize systemic absorption is to occlude the tear drainage after giving the drops. Pressing gently on the inner corner of the eye where the lacrimal puncta are located blocks the nasolacrimal ducts temporarily, reducing drainage into the nasal mucosa and thus limiting how much of the drug gets absorbed systemically. Holding this pressure for about a minute keeps more medication in the eye to work locally and lowers the chance of systemic side effects, which is especially important in children. Rubbing the eyes after instillation doesn’t prevent absorption and can spread the medication or irritate the eye. Having the child look upward with eyes open doesn’t seal off drainage paths. Wipeing away discharge removes residue but doesn’t affect how much drug enters systemic circulation.
