F4 · Fluid build-up in the body
Actual Food and fluids
Definition
The body holds too much fluid, causing swelling, quick weight gain, or breathlessness.- Heart failure
- kidney failure
- too much intravenous fluid
- liver disease
- Swelling
- quick weight gain
- breathlessness
- bulging neck veins
📋 Scenario
A dialysis patient gains 3 kg between sessions and has swollen ankles.
Subjective (S): "My ankles are swollen and I get breathless."
Objective (O): Weight up 3 kg between dialysis sessions; pitting edema 2+; blood pressure 168/94; neck veins distended.
Assessment tools for this scenario: CP-FLUID Fluid Balance & Nutrition Score CP-SKIN Skin & Wound Score CP-BREATH Breathing & Circulation Check
Validated scales to consider: MUST, fluid chart, glucose, Braden Scale, TIME wound chart, NEWS2, SpO₂, ECG
**CarePath diagnosis:** Fluid build-up in the body related to kidney failure and fluid taken between dialysis sessions, as evidenced by 2+ swelling, a 3 kg weight gain, and distended neck veins.
**Interventions and rationale**
| Intervention | Rationale |
|---|---|
| Measure fluids in and out. | Measuring fluids in and out shows whether more fluid is being kept than lost. |
| Weigh daily. | Daily weight is the most reliable sign of fluid change, because each kilogram gained is about a liter of fluid. |
| Limit fluids and salt as ordered. | Salt holds water in the body, so limiting salt and fluid reduces build-up, especially when the kidneys cannot remove it. |
| Raise legs. | Raising the legs helps fluid drain from the ankles back into the circulation. |
| Give diuretics as ordered. | Diuretics increase urine output to remove extra fluid, and are given as ordered because their effect depends on how well the kidneys work. |
**Expected outcomes**
- Weight gain between sessions under the doctor's target (often under 2 kg).
- Swelling reduced.
- Breathing comfortable.
- Patient states the fluid limit and a plan to keep to it.
**Linking the data to the diagnosis**
The dialysis patient gained 3 kg between sessions and has pitting edema 2+, blood pressure 168/94 and distended neck veins. He says his ankles are swollen and he gets breathless. This is an actual problem because extra fluid is already being held. Fluid in the lungs could be confused with it, but no frothy sputum or very low oxygen is described, so this wider fluid statement fits better. The plan aims for weight gain between sessions under the doctor's target (often under 2 kg), less swelling, comfortable breathing, and the patient stating the fluid limit and a plan to keep to it.
