| This is critical in calculating I&O!! | ACCURACY!! |
| Edema is: | swelling |
| Fluid loss is also known as: | dehydration |
| S/S of dehydration include: | low blood pressure, increased heart rate, fatigue, dry mucous membranes, strong/concentrated urine |
| What types of patients would be ordered I&O? | Dehydrated, IV fluids, surgery, urinary catheter, vomiting/diarrhea, cardiology or renal patients |
| What is considered "intake"? | Anything the patient takes orally, tube feeding, IV, or irrigation. This includes anything that MELTS at room temperature! |
| What is considered "output"? | Any excretions from the body that are LIQUID and MEASURABLE!!! |
| How is I&O calculated? | calculate per shift and then the total I&O is calculated for 24 hours and the two numbers are subtracted. |
| How is I&O calculated? | -- If the patient has MORE intake than output, they are said to be POSITIVE for the day. If they have LESS intake than output, they are said to be NEGATIVE for the day. |
| What unit of measurement do we use to document I&O? | cc or ml |
| How do you calculate oral intake? | Identify how many cc/ml the container holds. Estimate how much the person drank (1/3, 2/3, 1/2, etc.) Multiple that fraction by the total amount the container holds. Document in cc or ml. |
| Ex. for calculating | Ex. Container holds 240 cc of coffee, patient drank 1/3 cup, 1/3 x 240 = 80. Document 80 cc |
