2 Nutrition and Hydration

Why Nutrition and Hydration Matter

Nutrition provides energy and nutrients for growth, tissue repair, immune function, and daily activity. Hydration supports circulation, temperature regulation, digestion, and kidney function. Care should promote adequate intake while respecting each person's health needs, abilities, preferences, and cultural practices.

Assessing Nutritional Needs

A Nutritional assessment begins with a screening process and follows local policy for referral or comprehensive assessment. Ask about recent weight changes, appetite, usual food and fluid intake, and changes in eating patterns. Also consider medical conditions, medications, supplements, allergies, dietary restrictions, oral health, symptoms, and a person's ability to obtain or prepare food.

Explore food access, preferred foods, cultural or religious practices, and the assistance needed at meals. Measure and trend height and weight as appropriate, and calculate Body mass index (BMI) when indicated. Observe muscle and fat stores, skin, strength, oral health, and signs of fluid retention. Meal records and intake/output measurements may help when clinically indicated.

Screening tools identify risk but do not replace assessment. Laboratory tests may help investigate a concern, but no single laboratory value establishes nutritional status on its own. Unintentional weight loss, persistently poor intake, weakness, or signs of nutrient deficiency warrant follow-up and often referral to a registered dietitian.

Planning Food That Fits the Person

A balanced eating pattern generally includes vegetables, fruits, grains, protein foods, and dairy or fortified alternatives, with appropriate fluid intake. Energy and nutrient needs differ with age, body size, activity, pregnancy or lactation, illness, and recovery. Therapeutic diets may be needed for particular conditions, but restrictions should be individualized to avoid unnecessarily reducing intake.

For example, a person with poor appetite may find small, nutrient-dense meals more manageable than large portions. Older adults may need fewer calories while still benefiting from nutrient-dense foods. Inadequate intake of protein, calcium, vitamin D, vitamin B12, potassium, or fiber can be a concern; discuss individual needs and possible supplementation with a clinician.

Supporting Hydration

Fluid needs vary. Fever, vomiting, diarrhea, heat, activity, medications, and some illnesses can change requirements. Offer fluids regularly when permitted, particularly to people who may not recognize or communicate thirst. Follow prescribed fluid limits and swallowing instructions; more fluid is not appropriate for everyone.

When ordered or clinically indicated, monitor intake and output alongside weight trends, vital signs, mental status, urine output, and signs of fluid excess or deficit. Thirst, dry mouth, dizziness, fatigue, and reduced or dark urine may occur with dehydration, but no single sign reliably determines hydration status. Report concerning changes promptly.

Assisting With Meals and Swallowing Safety

Support independence during meals. Provide adaptive utensils or set-up help when useful, allow enough time, and confirm the ordered diet and level of assistance before helping. Position the person upright, ensure glasses or dentures are in place if used, reduce distractions when needed, and offer small bites or sips at a comfortable pace. Make sure each bite is swallowed before offering another. Document intake and report poor intake.

Coughing, choking, throat-clearing, a wet or gurgly voice, or difficulty coordinating breathing and swallowing may indicate Dysphagia. Stop feeding and report the concern according to facility protocol; seek a swallowing assessment. Follow the person's assessed plan: do not independently change food texture, thicken liquids, or use a swallowing maneuver unless that plan directs it. Aspiration may occur without obvious coughing, so an apparently easy meal does not rule out risk.

Common Concerns and When to Escalate

Respond to nutrition concerns by looking for possible causes and following the person's care plan:

• Poor appetite or unintended weight loss: Check for pain, nausea, oral problems, medication effects, mood changes, illness, and barriers to obtaining or preparing food. Offer preferred foods and smaller, more frequent meals when appropriate, and report ongoing concerns.

• Chewing difficulty or dry mouth: Check oral health and denture fit, provide appropriate oral care, and arrange evaluation as needed.

• Dysphagia: Follow the individualized swallowing plan and promptly refer suspected problems. It can contribute to inadequate intake, dehydration, and aspiration.

• Constipation or diarrhea: Record relevant symptoms and intake. Encourage fluids or fiber only when appropriate to the person's condition and orders, and report persistent symptoms.

• Food insecurity or restrictive diets: Ask sensitively about access, cost, preferences, and restrictions. Coordinate with a dietitian, social worker, or community resources as appropriate.

• Severe undernutrition: Escalate for clinical assessment before substantially increasing intake; some patients need carefully monitored nutritional rehabilitation.

Takeaway: Assess intake, weight trends, eating ability, health conditions, and personal circumstances. Promote individualized food and fluid choices, preserve independence during meals, follow swallowing instructions, and report persistent poor intake, unintended weight loss, dehydration concerns, or unsafe swallowing signs.
