Which assessment finding would be most consistent with presbyopia? ## 보기 1. Inability to see distant objects clearly while near vision remains intact 2. Difficulty focusing on close objects while distant vision remains relatively unaffected **✔ 정답** 3. Complete loss of peripheral vision with central vision preserved 4. Sudden onset of severe eye pain with halos around lights **정답: 2** ## 해설 Presbyopia is an age-related loss of lens flexibility, causing difficulty focusing on close objects while distant vision remains normal. Other options describe myopia, peripheral vision loss, or acute conditions like glaucoma. ## 심화 해설 Understanding Presbyopia Presbyopia is an age-related, gradual loss of the eye's ability to focus on close objects. The underlying mechanism is a progressive hardening of the crystalline lens, which reduces its elasticity and impairs accommodation—the process by which the lens changes shape to focus on near objects. This is distinct from refractive errors like myopia, which affects distance vision. Analysis of Assessment Findings The client's report of difficulty seeing objects clearly at close range is the hallmark symptom of presbyopia. In a 65-year-old client, this is an expected physiological change. The most consistent assessment finding would be that their difficulty is specific to near vision tasks, while their ability to see distant objects remains relatively unaffected. This occurs because the rigid lens can no longer increase its convexity sufficiently to refract light from near objects onto the retina, whereas the flatter configuration needed for distance vision is still passively maintained. Why Other Options Are Incorrect - **Inability to see distant objects clearly while near vision remains intact** describes myopia (nearsightedness), a refractive error typically caused by an elongated eyeball or excessively curved cornea, not age-related lens hardening. - **Complete loss of peripheral vision with central vision preserved** is a classic late finding in chronic open-angle glaucoma, resulting from progressive damage to the optic nerve, and is not related to the accommodative mechanism of the lens. - **Sudden onset of severe eye pain with halos around lights** is a hallmark of acute angle-closure glaucoma, a medical emergency caused by a sudden blockage of aqueous humor drainage, leading to a rapid increase in intraocular pressure. This presentation is acute and painful, completely unlike the gradual, painless blurring of presbyopia. Clinical Context from Current Research The progression of presbyopia is strongly age-dependent, but research also explores contributing lifestyle factors. A study measuring near add power in over 6000 individuals found that presbyopia progresses throughout life and its severity can be influenced by modifiable behaviors [1]. This highlights that while age is the primary driver, a comprehensive nursing assessment should also consider lifestyle elements when evaluating a client's visual complaints and planning health education. The core pathophysiology, however, remains the gradual loss of lens accommodation, which directly explains why option 2 is the most consistent assessment finding [1].References (research sources) - [1]Drinking Habit Could Exacerbate the Progression of Presbyopia in Men.Research articleAyaki M, Hanyuda A, Negishi K. (2026) · DOI: 10.2147/opto.s603879 ## 임상 시나리오 Clinical Guide to Presbyopia AssessmentDifferentiating age-related near vision loss from other ocular disorders The hallmark of presbyopia is a gradual, bilateral difficulty focusing on close objects, typically beginning after age 40. Distance vision remains relatively unaffected because the rigid lens can still maintain a flatter configuration for far focus. During a visual assessment, use a near-vision chart (e.g., Jaeger card) held 14 inches away. The client may unconsciously move the chart farther back to compensate. This is distinct from myopia, where distance vision is primarily impaired. CautionDo not confuse presbyopia with sudden vision changes. Acute angle-closure glaucoma presents with sudden severe eye pain, halos around lights, and requires immediate referral. Chronic open-angle glaucoma causes gradual peripheral vision loss, not central near-vision blur. ## 핵심 개념 - **Presbyopia** — Age-related, gradual loss of the eye's ability to focus on close objects due to hardening of the crystalline lens and reduced elasticity. - **Accommodation** — The process by which the eye's lens changes shape to focus on near objects; impaired in presbyopia. - **Myopia** — Nearsightedness; a refractive error where distant objects appear blurry, typically caused by an elongated eyeball or excessive corneal curvature. - **Glaucoma (Chronic Open-Angle)** — A condition characterized by progressive optic nerve damage, often presenting with gradual loss of peripheral vision. - **Crystalline Lens** — The transparent structure behind the iris that focuses light on the retina; its progressive hardening causes presbyopia. ## 같은 주제 문제 - [A nurse is conducting a visual assessment on a 65-year-old client who reports difficulty s…](https://mymerci.kr/pages/nclex_q.php?qn_id=541537) - [A nurse is conducting a vision assessment on a 58-year-old client who reports difficulty s…](https://mymerci.kr/pages/nclex_q.php?qn_id=541539) - [A nurse is conducting a visual assessment on a 65-year-old client with diabetes mellitus. …](https://mymerci.kr/pages/nclex_q.php?qn_id=541540) --- More free questions: [기출문제](https://mymerci.kr/) _학습 참고용입니다. 실제 임상은 최신 지침과 소속 기관 프로토콜을 따르세요._
