Section 6.3: Nutrition, Feeding Assistance, & Hydration (Thickened Liquids)

Providing proper nutrition and hydration is essential for maintaining a resident’s cellular health, tissue integrity, immune function, and overall quality of life. In long-term care facilities, the Certified Nursing Assistant (CNA) plays a critical role in assisting residents with eating, monitoring fluid intake, recognizing signs of dysphagia (difficulty swallowing), and executing aspiration precautions. These duties must comply with the federal and state mandates set forth in Iowa Administrative Code 441 Chapter 81, which require facilities to meet the nutritional and hydration needs of each resident according to their individualized care plan.

Feeding Assistance and Promoting Dignity

Mealtime should be a social, pleasant, and dignified experience. When assisting a resident who cannot feed themselves:

• Dignified Positioning: The CNA should sit at eye level, directly facing the resident. Standing over a resident while feeding them is undignified and can make them feel rushed.
• Engagement: Converse with the resident, explain what foods are on the plate, and ask in what order they would like to eat their food.
• Pacing: Offer small, manageable bites (about 1/2 to 1 teaspoon) and ensure the resident has swallowed the current bite completely before offering the next. Use adaptive utensils (e.g., weighted spoons, plate guards) as specified in the care plan to promote independence.

Dysphagia and Aspiration Precautions

Aspiration occurs when food, liquids, or saliva enter the trachea and lungs instead of the esophagus and stomach. This can lead to chemical pneumonitis or bacterial aspiration pneumonia, which is a leading cause of hospitalization and death among long-term care residents. Dysphagia is the medical term for difficulty swallowing, common in residents with Parkinson's disease, dementia, stroke history, or neuromuscular disorders.

Signs of Dysphagia and Aspiration

During feeding, the CNA must closely monitor the resident for signs of difficulty swallowing, including:

• Coughing, throat clearing, or choking during or immediately after swallowing.
• Watering eyes or running nose while eating.
• A 'wet,' gurgling, or hoarse vocal quality after swallowing.
• Pocketing food (storing unswallowed food in the side of the cheek).
• Rapid breathing or shortness of breath during meals.
• Frequent throat clearing or difficulty initiating a swallow.

If any of these signs occur, the CNA must stop feeding the resident immediately, sit them upright, and notify the charge nurse.

Positioning Protocol

To minimize the risk of aspiration, the resident must be positioned in a high Fowler's position (75 to 90 degrees) during meals. If the resident is bedbound, the head of the bed must be elevated to this angle, supported by pillows to maintain alignment.

• Post-Meal Positioning: The resident must remain in an upright or high Fowler's position for at least 30 to 45 minutes after eating. Gravity helps ensure that food and liquids clear the esophagus and stomach, preventing reflux and subsequent silent aspiration.

Hydration and Thickened Liquids

Dehydration is a prevalent and dangerous condition in the elderly, leading to urinary tract infections (UTIs), acute confusion, constipation, and renal failure. CNAs should frequently offer water and preferred fluids to residents who can swallow safely.

Thickened Liquid Consistency Levels

For residents with diagnosed dysphagia, thin liquids (like plain water or coffee) flow too quickly down the throat, entering the airway before the epiglottis has time to close. To slow down the flow of fluid, a physician or speech-language pathologist (SLP) will order thickened liquids. There are three standard levels of thickness:

1. Nectar Thick (Nectar Consistency): The liquid is pourable and has the thickness of apricot nectar or tomato juice. It can be drunk from a cup.
2. Honey Thick (Honey Consistency): The liquid has the thickness of honey, dripping slowly from a spoon. It can be drunk from a cup, but very slowly.
3. Pudding Thick (Spoon Thick): The liquid holds its shape and has the thickness of pudding. It cannot be drunk from a cup and must be eaten with a spoon.

Critical Safety Violation

Serving unthickened thin liquids to a resident with a thickened liquid order constitutes severe clinical neglect and is a major violation of Iowa Department of Inspections, Appeals, and Licensing (DIAL) standards. The CNA must double-check the care plan before serving any fluid, use pre-thickened liquids or add commercial thickener precisely according to manufacturer instructions, and ensure no thin liquids (including water pitchers at the bedside) are accessible to the resident.

Documentation of Intake and Output (I&O)

Accurate documentation of a resident's intake is vital for monitoring nutritional status and renal/cardiac health.

Food Intake

Food consumption is recorded as a percentage of the total meal eaten (e.g., 25%, 50%, 75%, 100%, or 'refused'). The CNA must inspect the tray and estimate the amount consumed, excluding inedible portions.

Fluid Intake and Conversion

Fluid intake is measured and documented in milliliters (mL) or cubic centimeters (cc). (Note: 1 mL is equivalent to 1 cc).

• The 30 mL Conversion Rule: CNAs must memorize that 1 fluid ounce (oz) equals 30 mL (or 30 cc).
• To calculate fluid intake, multiply the number of ounces consumed by 30.
  • Example 1: If a resident drinks a 4 oz cup of cranberry juice: 4 oz * 30 = 120 mL.
  • Example 2: If a resident drinks an 8 oz carton of milk: 8 oz * 30 = 240 mL.
  • Example 3: If a cup holds 8 ounces, and the resident drinks half of it (4 oz): 4 oz * 30 = 120 mL. The CNA must document the total in mL on the daily flow sheet.
