Final answer:
A client with a detached retina is most likely to report severe eye pain as a symptom, which aligns with option a from the question.
Step-by-step explanation:
A nurse assessing a client with a detached retina should expect the client to report symptoms that are characteristic of this condition. A detached retina can cause various visual disturbances, including the sensation of a veil or curtain over the field of vision, a sudden increase in floaters, which are small specks or cobwebs that drift through the field of vision, and flashes of light.
Among the options provided, the symptom that a client is most likely to report is a decrease in peripheral vision, not an improvement. Therefore, option b, 'Improved peripheral vision', is incorrect. Option c, 'Decreased floaters', is the opposite of what is typically experienced. Option d, 'Decreased intraocular pressure', is not directly associated with a detached retina, as the condition does not necessarily affect intraocular pressure. Excessive intraocular pressures are more associated with glaucoma. Therefore, option a, 'Severe eye pain,' is the most likely symptom a client with a detached retina might report.
