October 20, 2025 •

2 min read

According to the World Health Organization, malnutrition affects people globally, including undernutrition and overnutrition. Nurses play a central and crucial role in addressing this widespread health issue, leveraging their continuous patient interaction to identify, intervene, and monitor nutritional status.

Quick Summary

This guide details the essential nursing process for treating malnutrition, from initial screening and assessment using validated tools to implementing various nutritional support strategies and coordinating with the broader healthcare team.

Key Points

Screening is crucial: Nurses use validated tools like MUST and SGA during admission to identify patients at risk for or with malnutrition.
Tailored Interventions: Treatment ranges from oral supplements and modified diets to advanced enteral or parenteral nutrition, depending on the patient's needs.
Multidisciplinary Collaboration: Nurses coordinate with dietitians, physicians, and other specialists to create integrated, evidence-based care plans.
Comprehensive Monitoring: Regular monitoring of weight, food intake, and laboratory values is essential to evaluate the effectiveness of interventions and adjust care plans.
Patient and Family Education: Educating patients and their families about nutrition, meal planning, and community resources is vital for sustained nutritional health post-discharge.
Addressing Barriers: Nurses address challenges that can impair nutritional intake, such as dysphagia, nausea, and social or psychological issues.
Continuity of Care: Planning for nutritional care during transition points, such as hospital discharge, helps prevent relapse into malnutrition.

As frontline healthcare professionals, nurses are in a prime position to identify and intervene in cases of malnutrition. The process involves a structured, multi-step approach that is foundational to providing holistic patient care. By mastering these steps, nurses can significantly improve patient recovery and overall health outcomes.

The Nursing Process: A Step-by-Step Approach

1. Assessment and Screening

Nurses screen patients for malnutrition risk upon admission using validated tools and conduct physical exams and gather dietary history. More details on this process can be found on {Link: PowerTech Journal powertechjournal.com} and {Link: Wiley Online Library onlinelibrary.wiley.com}.

2. Implementation of Nutritional Interventions

Following assessment, nurses collaborate with the healthcare team to create a tailored care plan. This can include oral nutritional support through dietary modifications and supplements, or alternative methods like enteral or parenteral nutrition for patients unable to eat orally.

3. Monitoring and Evaluation

Vigilant monitoring tracks the patient's response to treatment. This involves tracking intake and weight, laboratory monitoring, and observational assessment. Refer to {Link: PowerTech Journal powertechjournal.com} and {Link: Wiley Online Library onlinelibrary.wiley.com} for more details.

4. Patient and Family Education

Nurses educate patients and families for adherence and post-discharge success. This includes guidance on meal planning, management of specific feeding methods, and community resources.

Comparing Nursing Interventions for Malnutrition


Intervention Type	Method of Delivery	Advantages	Considerations
Oral Nutritional Support	Nutrient-dense foods, small frequent meals, supplements (e.g., shakes)	Non-invasive, psychologically comforting, promotes normal eating	Requires patient cooperation, may not be sufficient for severe cases
Enteral Nutrition (Tube Feeding)	Feeding tube into the stomach or small intestine	Delivers precise nutrients, bypasses oral difficulties, safer than PN	Risk of aspiration, tube displacement, potential for gastrointestinal upset
Parenteral Nutrition (IV)	Intravenous administration into a vein	Used when GI tract is non-functional, delivers complete nutritional formula	Highest risk for infection (sepsis), requires central line access, expensive
Nutritional Counseling	Patient and family education by nurses and dietitians	Empowers patients with knowledge, supports long-term lifestyle changes	Requires patient engagement, may not address immediate energy deficit

Conclusion

Nurses are vital in combating malnutrition through screening, intervention, and monitoring. Their collaboration with the healthcare team, patient education, and use of various nutritional supports ensure patients receive necessary nourishment for healing.

Frequently Asked Questions

The first step is a nutritional screening upon admission using validated tools like the Malnutrition Universal Screening Tool (MUST) or Subjective Global Assessment (SGA) to identify if a patient is at risk.

Common interventions include providing oral nutritional supplements, modifying diets to be calorie- and protein-dense, providing mealtime assistance, and managing enteral (tube) or parenteral (IV) nutrition for more severe cases.

Nurses monitor progress by tracking weight changes, keeping detailed food and fluid intake records, assessing physical signs of improvement, and monitoring specific lab values like serum albumin and prealbumin.

Dietitians collaborate closely with nurses and physicians to perform comprehensive nutritional assessments, develop individualized nutrition plans, and provide specialized dietary counseling.

Enteral nutrition delivers nutrients directly to the gastrointestinal tract via a feeding tube, while parenteral nutrition delivers nutrients intravenously, bypassing the GI tract entirely.

Nurses provide education through counseling sessions, demonstrate proper feeding techniques, explain the importance of balanced diets, and provide resources for continued nutritional support after discharge.

Nurses look for signs such as unintentional weight loss, visible muscle wasting, changes in skin or hair integrity (e.g., dry skin, brittle hair), poor wound healing, and edema (swelling).
