A middle aged adult client reports a sudden onset of seeing flashing lights and floating spots. Which is the best nursing action?

Rationale: A. Initiate a referral for ophthalmic evaluation as soon as possible: Sudden onset of flashing lights and floaters may indicate retinal detachment or a retinal tear, which are ophthalmic emergencies. Prompt evaluation by an eye specialist is critical to prevent permanent vision loss. B. Advise the client to maintain normal activities, but avoid contact sports until the spots resolve: Continuing normal activities without urgent evaluation could delay treatment for a potentially serious retinal condition, increasing the risk of vision loss. C. Tell the client to apply warm, moist compresses and notify the healthcare provider (HCP) if there is no improvement: Warm compresses do not treat retinal tears or detachment. Waiting for symptoms to resolve can result in permanent damage. D. Instruct the client to rest, and report to the emergency department (ED) if eye pain develops: Retinal detachment may occur without pain, so waiting for pain to develop before seeking care is unsafe and may lead to irreversible vision loss.
