Which dietary instruction should the nurse provide to help improve the client's condition? ## 보기 1. Increase consumption of red meat and liver 2. Include dark green leafy vegetables and citrus fruits in daily meals **✔ 정답** 3. Take iron supplements with vitamin C 4. Consume dairy products and fortified cereals with vitamin B12 **정답: 2** ## 해설 Dark green leafy vegetables and citrus fruits are rich in folate, essential for treating folate-deficiency anemia. Other options address iron or B12 deficiencies, not folate. ## 심화 해설 Understanding Folate-Deficiency Anemia Folate-deficiency anemia is a type of megaloblastic anemia characterized by the production of abnormally large, immature red blood cells. This occurs because folate is a vital micronutrient required for DNA synthesis and cell division. When folate is lacking, the rapidly dividing cells in the bone marrow cannot mature properly, leading to ineffective erythropoiesis and symptoms such as fatigue and pallor. The condition is often preventable through adequate dietary intake, as the human body cannot synthesize folate and relies on external sources [1,2]. Why the Correct Answer is Option 2 The nurse should instruct the client to include dark green leafy vegetables and citrus fruits in their daily meals. This is the most direct and effective dietary intervention for correcting a primary folate deficiency without introducing other nutritional variables that do not address the root cause. - Dark green leafy vegetables (such as spinach, kale, and broccoli) are naturally rich sources of dietary folate. Folate from whole foods is a superior strategy for correcting deficiency, as it provides the nutrient in its natural form alongside other synergistic co-factors [2,4]. - Citrus fruits (such as oranges, lemons, and grapefruits) are excellent sources of vitamin C, which is not only an antioxidant but also protects the labile folate molecule from oxidative destruction in the gastrointestinal tract, thereby enhancing its bioavailability [4]. Analysis of Incorrect Options Examining the other options through the lens of pathophysiology and dietary science reveals why they are less appropriate for this specific diagnosis. - Option 1: Increase consumption of red meat and liver. While liver is indeed a rich source of folate, this instruction is not the primary or safest recommendation. The core issue is a folate deficiency, and recommending red meat and liver primarily addresses iron or vitamin B12 intake, not folate. Furthermore, the nurse must consider that liver is high in vitamin A, and excessive intake can lead to toxicity [4]. This option fails to target the specific deficiency with the most appropriate, low-risk food sources. - Option 3: Take iron supplements with vitamin C. This instruction is the cornerstone of treatment for iron-deficiency anemia, not megaloblastic anemia. Iron supplements have no therapeutic effect on the defective DNA synthesis caused by folate deficiency. While vitamin C enhances iron absorption, this combination does nothing to replenish folate stores and would leave the underlying megaloblastic process unaddressed. - Option 4: Consume dairy products and fortified cereals with vitamin B12. This instruction is specifically tailored for vitamin B12 deficiency anemia. Dairy products and fortified cereals are primary sources of cobalamin. Although a deficiency in either folate or B12 can result in megaloblastic anemia, the treatments are distinct. Providing B12-rich foods will not correct anemia caused by a lack of folate, and doing so could delay effective treatment. Prolonged predominant feeding with nutritionally inadequate milk substitutes, such as unfortified goat milk which is low in folate, is a documented risk factor for severe folate-deficiency anemia, highlighting the critical distinction between milk-based B12 sources and folate-rich plant sources [1,3].References (research sources) - [4]Scoping review of micronutrient imbalances, clinical manifestations, and interventions.Research articleEnglish K, Uwibambe C, Daniels P, Dzukey E. (2025) · DOI: 10.5662/wjm.v15.i4.107664 ## 임상 시나리오 Dietary Management of Folate-Deficiency AnemiaPrioritizing natural folate and its protection The primary intervention is to increase intake of natural dietary folate. Instruct the client to consume dark green leafy vegetables (spinach, kale, broccoli) daily, as they are the richest sources. To maximize absorption, pair folate sources with citrus fruits (oranges, grapefruits). The vitamin C in these fruits protects the labile folate molecule from oxidative destruction in the gastrointestinal tract, enhancing bioavailability. CautionDo not confuse with pernicious anemia management. While liver contains folate, recommending it or B12 supplements does not address the specific deficiency. Always correlate dietary teaching with the confirmed diagnosis. ## 핵심 개념 - **Megaloblastic Anemia** — A type of macrocytic anemia characterized by the presence of abnormally large, immature red blood cells (megaloblasts) in the bone marrow, caused by impaired DNA synthesis due to folate or vitamin B12 deficiency. - **Folate (Vitamin B9)** — A water-soluble B vitamin essential for DNA synthesis, cell division, and red blood cell maturation. Rich dietary sources include dark green leafy vegetables, citrus fruits, legumes, and fortified grains. - **Microcytic Anemia** — Anemia characterized by smaller-than-normal red blood cells, most commonly caused by iron deficiency, which impairs hemoglobin synthesis. ## 같은 주제 문제 - [A nurse is assessing a patient with suspected folate-deficiency anemia.
