Final answer:
The correct action for the nurse to take after administering timolol eyedrops to a client with glaucoma is to press the nasolacrimal duct to minimize systemic absorption of the medication.
Step-by-step explanation:
After instilling timolol eyedrops for a client who has glaucoma, the nurse should take the following action: Press a nasolacrimal duct. This action is advised to minimize systemic absorption of the medication, which can reduce the risk of systemic side effects. By applying light pressure to the nasolacrimal duct (also known as the tear duct), which is located at the inner corner of the eye near the nose, the nurse helps to prevent the eye drops from draining into the nasal passage and then into the bloodstream. It's a simple step that can be quite important for enhancing the medication efficacy and client safety.
