Special Considerations in Planning and Implementation

General navigator

When monitoring strict I&O, account for incontinent urine, emesis, and diaphoresis, if possible. Weigh soiled linens to determine fluid loss, or estimate it. Enlist the aid of family members in obtaining accurate I&O measurements. Explain the rationale and procedure for monitoring I&O. When measuring output, always wear gloves to protect against exposure to body fluids. Consult pharmacology and treatment references if effects of medication or other therapy on fluid loss or gain are uncertain. Initiation of I&O is an independent nursing action. Initiate recordings if a client has risk factors for fluid loss or gain, such as not eating, receiving diuretic therapy, a diagnosis associated with fluid or blood loss, or excessive drainage from a wound.

Pediatric navigator

Weigh diapers to give a rough estimate of output (1 g of weight = 1 mL of fluid).

Geriatric navigator

For incontinent clients, weigh linens, waterproof pads, or incontinence briefs as a rough estimate of output (1 g of weight = 1 mL of fluid). Anticipate the need for monitoring I&O for older clients who are at risk for dehydration because of poor fluid intake, thin and fragile skin (more prone to environmental insults), and decreased response to thirst, among other factors.

End-of-Life Care navigator

Consider the desires of the client and family, doctor's orders, and agency policies related to fluid and nutrition therapy for end-of-life clients; food and drink are associated with health, comfort, and love by many clients and families. Assess dying clients for dehydration, such as from a decreased ability to swallow and a subsequent decrease in blood volume.

Home Health navigator

If the homebound client has difficulty understanding units of measure or seeing calibration lines, make an I&O sheet including columns for common household measurement devices, such as drinking glasses, cups of ice, or bowls of Jell-o and soup to represent intake; the client can cross off or check these off. Have client measure output by number of voidings.

Image_Transcultural Transcultural navigator

In various cultures, health, comfort, and love are associated with food and drink through traditions and rituals. Exercise cultural sensitivity when caring for clients who are on various food and fluid restrictions, and allow the client and family to verbalize concerns.

Delegation navigator

Measuring I&O is often delegated to unlicensed personnel. However, IV intake must be added to intake totals, and the nurse must always check the information gathered and report any evidence of fluid overload or deficit.

Implementation

ActionRationale
1Perform hand hygiene and organize equipment.Reduces microorganism transfer; promotes efficiency
2Post pad on door or in room and instruct team members to record I&O. Instruct client and family on use of I&O record with return demonstration. (If calorie count is in progress, list type of food and fluid consumed as well.)Ensures complete, accurate record of I&O allows dietary department to calculate caloric intake correctly based on standard institutional serving sizes
3Measure oral intake:Takes into account the wide variety of fluids consumed orally
  • Place graduated cups in room before consumption.
Ensures consistency and common units of measurement and minimizes error
  • Record semisolid substance intake in percentage or fraction of amount based on institution’s use standard portions.
Provides measurement of foods that would be liquid at room temperature
  • Note volume of water in pitcher at beginning of shift plus any fluid added and subtract fluid remaining in pitcher at end of shift.
Provides measurement of water intake
  • Note amount of ice chips consumed, multiply volume by 0.5 and record amount.
When melted, the volume of ice is approximately half its previous volume.
  • Measure all liquids, such as juices, other beverages, Jell-o, ice-cream, sherbet, and broth using graduated devices, package volume, or standard volume measurements from institution’s food services.

Includes all sources of ingested fluids for accurate measurements
4Measure nasogastric (NG) or gastric tube feeding:Maintains accurate record by including gastrointestinal (GI) intake in addition to oral intake
  • Note volume of feeding hanging at beginning of shift or volume amount on feeding pump readout (amount left from previous shift) plus any amount added during shift; allow prior feeding to infuse almost totally before adding new solution.
Ensures accuracy of measurement to include all fluids given; indicates volume infusing during current shift; prevents feeding from hanging for more than 8 hr
  • Subtract feeding volume remaining at end of shift (or read infusion total from pump if previous shift has cleared pump total).
Provides measurement of NG or gastric tube intake
  • Record amount of fluid used to mix any liquid, oral, or NG medications.
Maintains complete I&O measurement
5Measure all IV intake using same methodology as in Step 4. Volume of each type of intake is often designated on flow sheet (e.g., colloids, blood products).Ensures complete and accurate monitoring of all intake regardless of source
6If NG irrigation is performed and irrigant is left to drain out with other gastric contents, enter irrigant in intake section of flow sheet (or subtract irrigant amount from total output; see Step 10).Ensures accurate accounting of retained fluid
7

Measure output:Ensures measurement of output using standardized measurement units
  • Place one or more graduated containers (size dependent on fluid or drainage being measured) in the room; for small amounts of drainage such as from wounds, place clearly marked graduated cup in room.

Prevents use of cup for measuring intake
  • For drainage measurement, designate whether urine measurement from urinal will be used or if urine should be poured into graduated containers.

Helps to maintain standardized measurement units to promote accuracy
  • Measure output, including NG or gastrostomy tube drainage, ostomy drainage or liquid stool, wound drainage, chest tube drainage, urinary catheter drainage or voiding, emesis, blood or serous drainage, and extreme diaphoresis.

Ensures measurement of all sources of output
  • Weigh soiled pads or linens and subtract dry weight to estimate output.
Promotes complete measurement
8At the end of each shift, or hourly if needed, wear gloves and empty drainage into graduated container. Alternatively, mark the level of drainage on a tape strip on the container with date and time (Fig. 7.1), or calibrate in intervals of desired number of hours. When container is nearly full, empty it or dispose of it and replace with new container.Minimizes exposure to body fluids during measurement; allows monitoring on a more frequent basis; ensures uninterrupted measurement of output
9Record amount and source of drainage, particularly with drains from different sites.Identifies drainage amounts from specific sites
10If intermittent or ongoing irrigation is performed, calculate true output (urinary or NG) by measuring total output and subtracting total irrigant infused.Eliminates double counting of output
11At the end of a 24-hr period, usually at end of evening or night shift, add total intake and total output. Report extreme discrepancy to doctor (e.g., if input is 1–2 L more than output). Correlate weight gains with fluid intake excesses.Provides an indication of I&O status over a 24-hr period; identifies possible fluid overload situations; helps determine if third spacing is occurring
12Clean containers and store in client’s room.Reduces microorganism transfer; prepares equipment for future use
13Remove and discard gloves and perform hand hygiene.Reduces microorganism transfer
