## 문제

A nurse is developing a comprehensive care plan for a client with advanced lung cancer who is experiencing cancer cachexia syndrome and receiving palliative chemotherapy. The client reports severe fatigue, decreased appetite, and weight loss of 15 pounds over the past month. Laboratory results show hemoglobin 8.2 g/dL, albumin 2.8 g/dL, and total protein 5.5 g/dL. What is the most appropriate nursing intervention to address the client's nutritional status?

## 보기

1. Encourage the client to consume three large meals per day with high-calorie supplements
2. Recommend a strict high-protein diet with elimination of all simple carbohydrates
3. Provide frequent small meals with nutrient-dense foods and collaborate with the dietitian for individualized meal planning **✔ 정답**
4. Suggest the client fast intermittently to stimulate appetite and improve food tolerance

**정답: 3**

## 해설

Frequent small meals with nutrient-dense foods and dietitian collaboration address cancer cachexia by maximizing intake and providing individualized support. Other options are less effective or inappropriate for this syndrome.

Understanding Cancer Cachexia Syndrome

The client’s presentation of severe fatigue, decreased appetite, and significant weight loss in the setting of advanced lung cancer points to cancer cachexia syndrome, also referred to as anorexia-cachexia syndrome (ACS). This is not simple malnutrition. ACS is a multifactorial syndrome driven by a chronic pro-inflammatory state and complex metabolic derangements, including increased protein degradation and lipolysis [1]. This metabolic chaos means the weight loss and muscle wasting cannot be fully reversed by conventional nutritional supplementation alone [1]. However, inadequate intake of calories and protein will exacerbate the weight loss, making targeted nutritional support a critical nursing intervention [1]. The laboratory values support this diagnosis: a hemoglobin of 8.2 g/dL indicates anemia of chronic disease, while an albumin of 2.8 g/dL and total protein of 5.5 g/dL reflect a profound protein-energy deficit and the catabolic state.

Analysis of the Intervention Options

The core challenge in ACS is that systemic inflammation directly impacts a patient’s ability to eat. A prospective study confirmed a strong association between systemic inflammation and reduced energy and protein intake over time in patients with advanced cancer [4]. This physiological reality makes several of the proposed interventions ineffective or harmful.

- **Option 1 (Three large meals):** This approach ignores the hallmark symptoms of ACS: severe anorexia and early satiety. A patient struggling with appetite and inflammation-induced food aversion will likely find three large meals overwhelming, leading to even lower total daily intake.

- **Option 2 (Strict high-protein diet, eliminating simple carbohydrates):** While protein is crucial, a strict diet with unnecessary restrictions is counterproductive. The immediate goal is to maximize caloric intake by any means tolerated. Simple carbohydrates can be a valuable, easily digestible energy source for a cachectic patient. Furthermore, a meta-analysis of interventions for cancer cachexia emphasizes the benefit of combined nutritional and exercise interventions, not restrictive dieting, to mitigate cachexia-related impairments .

- **Option 4 (Intermittent fasting):** This is contraindicated. Fasting induces a further catabolic state and deprives the body of energy at a time of extreme metabolic stress. In ACS, where intake is already dangerously low due to inflammation [4], any period of intentional fasting would only accelerate the loss of lean body mass.

Why Option 3 is the Most Appropriate Intervention

Providing frequent, small, nutrient-dense meals directly addresses the physiological barriers of ACS. Small portions are less intimidating and help manage early satiety, making it more likely the client will consume adequate calories and protein over the entire day. This strategy aligns with the palliative management of ACS, which focuses on symptom control and quality of life, as evaluated in community palliative care settings . Collaborating with a dietitian is essential for individualizing the meal plan, ensuring it accounts for the client's specific metabolic needs, food preferences, and treatment side effects. This multidisciplinary approach is a cornerstone of effective cachexia management, as a single-discipline intervention is often insufficient for a syndrome with such complex metabolic and inflammatory drivers [1,2]. The combination of a practical nursing strategy with expert dietary collaboration provides the best chance to slow the downward spiral of weight loss and functional decline.References (research sources)

## 임상 시나리오

Managing Cancer Cachexia NutritionPrioritize Small, Frequent, Nutrient-Dense Meals
The primary dietary strategy for cancer cachexia is to provide frequent small meals of nutrient-dense foods. This approach works with the patient's limited appetite and early satiety, not against it.

Collaborate with a dietitian for individualized planning. The goal is to maximize protein and calorie intake per bite. A low serum albumin of 2.8 g/dL and total protein of 5.5 g/dL confirms severe protein-energy deficit requiring targeted intervention.

CautionDo not recommend three large meals, as they are poorly tolerated. Strict or restrictive diets and intermittent fasting are contraindicated, as they exacerbate the catabolic state and weight loss in cancer cachexia syndrome.

## 핵심 개념

- **Cancer Cachexia Syndrome** — A multifactorial syndrome characterized by ongoing loss of skeletal muscle mass, with or without loss of fat mass, that cannot be fully reversed by conventional nutritional support and is driven by systemic inflammation and metabolic dysregulation.
- **Early Satiety** — A premature feeling of fullness after eating only a small amount of food, commonly experienced by patients with advanced cancer due to tumor effects, altered gastric motility, or ascites.
- **Hypoalbuminemia** — A low level of albumin in the blood (less than 3.5 g/dL), often indicating malnutrition, chronic inflammation, or protein-losing conditions, and is a common finding in cancer cachexia.
- **Palliative Chemotherapy** — Chemotherapy administered with the primary goal of relieving symptoms, improving quality of life, and prolonging survival, rather than curing the underlying cancer.
