What major eye problem are clients most likely at increased risk for if a first-degree relative has it? glaucoma A middle-aged client reports difÏculty in reading. Which action by the nurse is appropriate to test the near visual acuity using a Jaeger reading card instruct the client to hold the chart 14 inches from the eyes0:0201:14 A nurse performs the Snellen test (distance) on a client and obtains these results: OD 20/40, OS 20/30. What conclusion can the nurse make in regards to the client's vision based on these results? The larger the bottom number the worse the visual acuity.

The nurse notices that the client squints when signing the consent for treatment form and holds the paper close to the face. What should the nurse do next?
