Correct Answer: C

Rationale: Vitamin C aids in the absorption of iron by enhancing the body's ability to absorb non-heme iron, which is found in plant-based foods. This vitamin helps convert iron into a form that is more easily absorbed in the intestines. Choices A, B, and D are incorrect because fiber, Vitamin A, and oxalates can actually inhibit the absorption of iron. Fiber can bind to iron and reduce its absorption, Vitamin A does not directly enhance iron absorption, and oxalates found in some foods like spinach and rhubarb can also hinder iron absorption.

Correct Answer: C

Rationale: The correct recommendation for managing gastroesophageal reflux disease is to avoid eating within 3 hours of bedtime. This helps prevent acid reflux by allowing food to digest before lying down. Choices A, B, and D are incorrect. Limiting fluid intake not related to meals is not a standard recommendation for managing GERD. Chewing on mint leaves may worsen symptoms as mint can relax the lower esophageal sphincter, allowing stomach acid to flow back up. Seasoning foods with black pepper does not specifically help manage GERD.

Correct Answer: B

Rationale: The nurse should recommend brewed iced tea as it generally contains less caffeine compared to other choices. Lemon-lime soda, diet cola, and chocolate milk all contain caffeine, which can contribute to sleep disturbances. Lemon-lime soda and diet cola are carbonated beverages that typically contain caffeine unless specified as caffeine-free. Chocolate milk also contains caffeine due to the cocoa content. Therefore, brewed iced tea is the most suitable choice to reduce caffeine intake and improve sleep quality.

Correct Answer: A

Rationale: Soybeans are a good source of high-quality protein. They contain all the essential amino acids needed by the body. Grains, legumes, and green vegetables do not provide as much high-quality protein as soybeans. Grains and legumes are good sources of protein but may lack some essential amino acids, while green vegetables generally have lower protein content compared to soybeans.

Correct Answer: C

Rationale: In pre-dialysis end-stage kidney disease, reducing intake of foods high in potassium is crucial as impaired kidney function can lead to potassium buildup in the blood, which can be dangerous. High potassium levels can cause irregular heartbeats and even cardiac arrest. Therefore, advising the client to reduce potassium-rich foods is essential to prevent complications. Choices A, B, and D are incorrect. Increasing dietary phosphorus, eliminating foods high in protein, or increasing sodium-containing foods are not appropriate recommendations for a client with pre-dialysis end-stage kidney disease as they can exacerbate the condition.
