A nurse administers pilocarpine eye drops. The nurse instructs the patient to press on the nasolacrimal duct for 30 seconds because the medication can have some systemic side effects, such as affecting the heart rate. Explain the rationale for pressing
on the nasolacrimal duct.
What will be an ideal response?
The nasolacrimal duct connects the eye to the nasal cavity. Applying pressure to the nasolacrimal duct prevents the drug from traveling from the eye to the nasal mucosa and general circulation, where it may affect heart rate.
