Top Nursing Diagnoses for Chronic Kidney Disease Stages 3-5
The three most critical nursing diagnoses for adults with advanced CKD presenting with fluid overload, hypertension, and electrolyte disturbances are: (1) Excess Fluid Volume, (2) Risk for Electrolyte Imbalance, and (3) Risk for Infection.
Primary Nursing Diagnoses
1. Excess Fluid Volume (100% prevalence)
This diagnosis appears universally in CKD patients stages 3-5 with fluid overload 1, 2. The pathophysiology stems from declining GFR below 60 mL/min per 1.73 m², which impairs the kidneys' ability to maintain fluid balance 3.
Key assessment parameters:
- Monitor 24-hour urine output (should be ≥0.8-1 L/day in patients with normal renal function not on diuretics) 4
- Daily weights and intake/output records
- Signs of volume overload: peripheral edema, pulmonary congestion, jugular venous distension
- Serum sodium concentrations (more commonly related to hydration status than sodium content in PN) 4
Critical interventions:
- Fluid restriction tailored to residual kidney function and urine output
- Loop diuretics for volume overload (thiazides become less effective as GFR declines) 5, 6
- Sodium restriction to <5 g/day 7
2. Risk for Electrolyte Imbalance (96.8-100% prevalence)
This diagnosis is nearly universal in advanced CKD patients 1, 2. As GFR declines below 60 mL/min per 1.73 m², the prevalence of electrolyte complications rises significantly 3.
Specific electrolyte concerns:
Hyperkalemia: Most critical risk, particularly with ACE inhibitors/ARBs 8
- Monitor serum potassium with awareness of measurement variability (diurnal/seasonal variation, plasma vs. serum samples) 8
- Implement dietary potassium restriction, limiting bioavailable potassium sources (especially processed foods) 8
- Consider potassium binders when needed to avoid discontinuing cardio-renal protective medications 7
Metabolic acidosis: Serum bicarbonate monitoring essential 8
Phosphate/calcium imbalance: Bone disease complications begin at stage 3 3
3. Risk for Infection (100% prevalence)
Universal in hemodialysis patients due to vascular access and immunocompromised state 1, 2. This diagnosis reflects both the uremic environment and invasive procedures required for treatment.
Assessment focus:
- Vascular access site monitoring (if applicable)
- Signs of systemic infection in immunocompromised state
- Uremic complications affecting immune function
Secondary High-Priority Diagnoses
4. Ineffective Health Management Related to Hypertension
Hypertension is both cause and complication of CKD and must be carefully controlled in all patients 3.
Blood pressure targets:
Antihypertensive strategy for stages 3-5:
- First-line: ACE inhibitors or ARBs for proteinuric disease 5
- Add thiazide diuretics (loop diuretics if volume overload present) 5
- Most patients require combination therapy 5
- Critical caveat: Monitor for hyperkalemia and acute GFR decline with ACE inhibitors/ARBs; implement potassium management strategies rather than discontinuing these prognostically beneficial medications 8, 7
5. Imbalanced Nutrition: Less Than Body Requirements
Malnutrition risk increases significantly when GFR <60 mL/min per 1.73 m² 3.
Nursing interventions:
- Registered dietitian nutritionist consultation is essential 9
- Monitor appetite, dietary intake, body weight changes, anthropometric measurements 9
- Assess for uremic symptoms affecting nutritional intake
- Individualized meal planning addressing protein, phosphorus, potassium restrictions while preventing malnutrition 9
6. Risk for Decreased Cardiac Output
CVD events are more common than kidney failure in CKD patients 3. CKD is considered highest risk group for subsequent cardiovascular events 3.
Assessment priorities:
- Left ventricular hypertrophy screening 3
- Anemia evaluation (begins stage 3) 3
- Volume status and blood pressure control
Clinical Action Plan by CKD Stage
Stage 3 (GFR 30-59 mL/min):
- Begin evaluation and treatment of complications: anemia, malnutrition, bone disease 3
- Intensify hypertension management
- Nephrology consultation if complications cannot be adequately managed 3
Stage 4 (GFR 15-29 mL/min):
- Mandatory nephrologist co-management (GFR <30 mL/min) 3
- Preparation for kidney replacement therapy 3
- Aggressive management of all complications
Stage 5 (GFR <15 mL/min):
- Preparation for dialysis/transplantation 3
- All previous interventions continue
Common Pitfalls to Avoid
Discontinuing ACE inhibitors/ARBs prematurely due to hyperkalemia or mild GFR decline—instead, implement potassium management strategies 8, 7
Using serum creatinine alone to assess kidney function—always calculate estimated GFR 10
Inadequate fluid assessment—relying solely on clinical signs rather than systematic monitoring of weights, intake/output, and urine volume 4
Late nephrology referral—associated with increased mortality; refer when GFR <30 mL/min 3
Prescribing nephrotoxic medications (NSAIDs, certain antibiotics) without considering renal function 6
Overlooking volume overload as cause of renal dysfunction—right heart failure and renal venous congestion can worsen kidney function 6
