10.2 Feeding Assistance, Hydration, and Intake/Output Recording

Key Takeaways

  • Feeding: sit at resident's level, spoon 1/3 full, feed at their pace, alternate food and fluids
  • Keep residents upright (Fowler's position) for 30 minutes after meals to prevent aspiration
  • Record meal intake as percentage: 0%, 25%, 50%, 75%, 100%
  • Fluid conversion: 1 oz = 30 mL; ice chips = half the volume as liquid
  • Report weight changes of 5 lbs/week or 10 lbs/month to the nurse immediately
  • Encourage hydration: offer fluids every visit, place water within reach, track I&O accurately

Feeding Assistance, Hydration, and Intake/Output Recording

Feeding and hydration is one of the 21 mandated INACE performance skills, and measuring and recording intake and output is another. These skills are fundamental to ensuring residents receive adequate nutrition and hydration for health and healing.

Feeding Assistance Procedure (INACE Skill)

Before the Meal:

  1. Wash hands and identify the resident
  2. Assist with toileting and hand hygiene before the meal
  3. Position the resident in Fowler's position (sitting upright at 90 degrees)
  4. Check the diet card against the tray — verify the correct resident, diet type, and allergies
  5. Remove tray covers and describe the food to the resident
  6. Check food temperature — should be appropriate for each item
  7. Cut food into bite-sized pieces if needed
  8. Offer condiments (if permitted by diet order)

During the Meal:

  1. Sit at the resident's level — do not stand over them
  2. Offer food in the order the resident prefers (ask them)
  3. Use a spoon (not a fork) for safer feeding
  4. Fill the spoon only 1/3 full to prevent choking
  5. Feed at the resident's pace — never rush
  6. Alternate between food and beverages
  7. Wipe the resident's mouth as needed with a napkin
  8. Allow time for chewing and swallowing before the next bite
  9. Encourage self-feeding whenever possible (adaptive utensils if needed)
  10. Engage in pleasant conversation (but not while the resident is chewing/swallowing)

After the Meal:

  1. Record the percentage of the meal eaten (0%, 25%, 50%, 75%, 100%)
  2. Record fluid intake in milliliters (mL) or cubic centimeters (cc)
  3. Remove the tray
  4. Provide mouth care
  5. Keep the resident upright for at least 30 minutes after eating (aspiration prevention)
  6. Report poor intake or refusal to eat to the nurse

Hydration

Adequate hydration is critical for elderly residents, who are at increased risk for dehydration:

Hydration FactDetails
Daily needMost adults need 1,500-2,000 mL (about 6-8 cups) of fluid daily
Dehydration riskElderly have decreased thirst sensation and may not drink enough
Signs of dehydrationDry mouth, dark urine, decreased urine output, confusion, dry skin, sunken eyes
CNA roleOffer fluids at meals and between meals; record intake; report inadequate intake

Encouraging Hydration:

  • Offer fluids every time you enter the room
  • Place water within reach at all times
  • Offer a variety of beverages (juice, milk, coffee, tea, water) per diet order
  • Serve beverages at the resident's preferred temperature
  • Use straws, cups with lids, or adaptive cups as needed
  • Track fluid intake on the I&O sheet

Measuring and Recording Intake and Output (INACE Skill)

Intake (I) — Everything that enters the body:

Intake ItemHow to Measure
Oral fluidsMeasure in mL; facility will have a conversion chart for cup/container sizes
Ice chipsRecord as half the volume (ice melts to about 50% volume of liquid)
Foods that meltGelatin, ice cream, popsicles — record as fluid
IV fluidsNurse records; CNA does not manage IVs
Tube feedingsNurse records; CNA does not manage tube feedings

Output (O) — Everything that leaves the body:

Output ItemHow to Measure
UrineMeasure in mL using a graduated container (hat, urinal)
Emesis (vomit)Estimate or measure in mL
Diarrhea/stoolDescribe frequency, consistency, and estimated amount
Wound drainageNurse assesses; CNA reports observations
Ostomy outputMeasure when emptying the ostomy bag

Common Measurement Conversions:

ContainerVolume
1 cup240 mL
1 oz30 mL
Standard water glass240 mL (8 oz)
Small juice glass120 mL (4 oz)
Coffee cup180-240 mL (6-8 oz)
Gelatin cup120 mL (4 oz)
Milk carton240 mL (8 oz)

Weight Measurement (INACE Skill)

Measuring and recording weight and height is another mandated INACE skill:

  • Weigh at the same time each day (usually before breakfast)
  • Use the same scale each time for consistency
  • The resident should wear similar clothing each time
  • Remove shoes before weighing
  • Report weight changes of 5 lbs in a week or 10 lbs in a month to the nurse
  • Weight loss may indicate: inadequate nutrition, illness, depression, swallowing problems
  • Weight gain may indicate: fluid retention, medication effects, dietary changes
