Which nursing intervention is the most appropriate to implement for a client who experiencing weight loss due to nausea caused by chemotherapy?

A. Automatically switching to liquid nutrition without assessing the client’s tolerance and needs may not be the most appropriate first step. It’s important to consider the client’s preferences, nutritional requirements, and overall ability to tolerate different types of food.
B. This is a highly appropriate and commonly recommended intervention for clients experiencing nausea and weight loss due to chemotherapy. Small, frequent meals can help manage nausea better than large meals and ensure a more consistent intake of calories and nutrients.
C. Eating one large meal per day is generally not advisable for clients with nausea, as it can exacerbate feelings of fullness and discomfort. Large meals may increase nausea and make it more difficult for the client to consume adequate nutrients. Small, frequent meals are generally better tolerated and more effective for managing nausea and ensuring consistent nutrient intake.
D. Inserting a nasogastric (NG) tube and administering tube feedings is a more invasive measure and is usually considered only if oral intake is severely compromised and other interventions have been ineffective. Tube feedings are appropriate for clients who cannot meet their nutritional needs through oral intake due to severe nausea, vomiting, or other conditions.

A. Loss of peripheral vision is a hallmark sign of primary open-angle glaucoma. In POAG, increased intraocular pressure causes damage to the optic nerve, leading to a gradual loss of peripheral vision. This vision loss is often subtle and progresses slowly, making it difficult for individuals to notice until the condition is advanced.

B. Opacity of the lens is characteristic of cataracts, not glaucoma. Cataracts involve the clouding of the eye's natural lens, which leads to blurred vision and difficulties with seeing clearly, particularly in bright light. While cataracts and glaucoma can occur simultaneously, opacity of the lens is not indicative of POAG.
C. Decrease in color perception can be associated with various eye conditions, including age-related macular degeneration (AMD) and certain types of retinal diseases. While it can occur in glaucoma as the disease progresses, it is not the primary or most characteristic sign of POAG.
D. Pain and purulent discharge are more associated with acute conditions such as conjunctivitis (pink eye) or an eye infection, rather than primary open-angle glaucoma. POAG typically presents without pain or discharge, as it is a chronic condition with a gradual onset of symptoms.
