A nurse is administering timolol eye drops to a client who has glaucoma. Which of the following actions should the nurse take?
A. Protect the distal portion of the eyedropper using clean technique.
Sterile technique should ideally be used when handling the distal portion of the eyedropper to prevent introducing pathogens into the eye, as the eye is a sensitive area susceptible to infection.
B. Wipe the eye from the outer canthus to the inner canthus before instillation.
When cleaning the eye, it is recommended to wipe from the inner canthus to the outer canthus to avoid bringing contaminants from the outer area closer to the tear duct, which reduces the risk of infection.
C. Apply pressure to the bridge of the nose after administration.
Applying pressure to the bridge of the nose is ineffective for preventing systemic absorption of the medication. Instead, pressure should be applied to the inner canthus (the nasolacrimal duct area) for about 1-2 minutes after instillation.
D. Drop prescribed amount of medication into the conjunctival sac.
The correct technique for administering eye drops involves placing the prescribed number of drops into the conjunctival sac, not directly onto the cornea, as this can cause irritation and discomfort. Administering drops into the conjunctival sac allows for better absorption of the medication.
