CAUTIs (Catheter-Associated Urinary Tract Infections) are the most common hospital-acquired infection. The best prevention: remove the catheter as soon as possible. Every day with a catheter = 3–7% increased infection risk.
Appropriate Indications for Foley Catheter
A catheter requires a clinical indication — not nursing convenience, not "easier to manage" incontinence. Document the indication at insertion and reassess daily.
Accepted Indications (NHSN/CDC)
- Acute urinary retention or obstruction
- Accurate urine output monitoring in critically ill patients
- Perioperative use for certain surgeries
- Assistance with pressure injury healing in incontinent patients (only for open wounds in perineal area)
- Comfort/palliative care as requested by patient
- Prolonged immobilization (pelvic fractures, unstable spine)
NOT Accepted Indications
- Urinary incontinence alone (no wound)
- Obtaining urine cultures (straight cath instead)
- Patient or family request (without clinical indication)
- Nursing staffing convenience
Foley Catheter Insertion Technique
Equipment Needed
- Sterile catheter kit (most include: catheter, drape, cleansing solution, gloves, syringe, collection bag)
- Appropriate catheter size: 14–16 Fr for most adults; 18 Fr for gross hematuria; 12–14 Fr for females
- Adequate lighting; patient privacy
Insertion Steps
- Verify order; explain procedure; obtain patient cooperation
- Position: female = supine with knees bent (lithotomy); male = supine with penis held perpendicular to body
- Open kit using sterile technique; don sterile gloves
- Drape perineum with sterile drapes
- Cleanse urethral meatus: females = front to back, 3 swipes (1 swipe each, discard); males = circular motion outward from meatus
- Lubricate catheter tip (included in kit)
- Insert catheter gently with dominant hand: females = 2–3 inches; males = 7–9 inches (until urine returns)
- Advance 1–2 more inches after urine returns before inflating balloon
- Inflate balloon with 10 mL sterile water (not saline); check for resistance
- Gently pull back until resistance is felt (balloon seated at bladder neck)
- Secure catheter to inner thigh (females) or lower abdomen (males); slack in tubing
- Drainage bag below bladder level; never on floor; tubing not kinked
If resistance felt during balloon inflation: STOP and deflate — catheter may still be in urethra. Inflating in urethra = urethral trauma and rupture.
Daily Catheter Care
- Perineal hygiene daily and after every bowel movement: clean meatus and at least 4 inches of catheter with soap and water; pat dry
- Maintain closed drainage system at ALL TIMES — do not disconnect for any reason without order
- Keep drainage bag below bladder at all times — prevents backflow
- Empty drainage bag when 2/3 full or every 8 hours; use clean technique; avoid contact between drain spigot and collection container
- Secure catheter to prevent tension and pulling; reposition with every position change
- Document urine output, color, clarity, odor, and any patient complaints
CAUTI Prevention Bundle
| Bundle Element | Action |
|---|
| Insert only when indicated | Verify clinical indication before every insertion; document clearly |
| Use sterile technique | No breaks in sterile field during insertion; use only sterile-lubricated catheters |
| Maintain closed system | Never disconnect catheter from drainage bag; use sample port for specimens |
| Keep drainage below bladder | Bag on floor = gravity backflow = bacteria → bladder; always hang bag |
| Daily necessity review | Ask: does this patient still need this catheter? Remove ASAP |
| Hand hygiene | Before AND after any catheter manipulation |
| Avoid routine irrigation | Do not irrigate unless ordered (clots, obstruction); each irrigation is a system breach |
| Secure catheter | Prevent pulling; reduces mucosal trauma and bacterial entry |
Automatic stop orders: Many hospitals have catheter automatic stop orders (e.g., remove after 2 post-op days unless renewed). Advocate for removal as soon as clinical condition allows.
Troubleshooting Common Problems
| Problem | Cause | Nursing Action |
|---|
| No urine output | Kinked tubing, clogged catheter, misplacement, hypovolemia | Check tubing for kinks; reposition patient; assess hydration; irrigate per order; notify MD if no resolution |
| Urine leaking around catheter | Catheter too small, bladder spasm, constipation | Check balloon inflation; do NOT upsize — upsizing worsens leakage; treat bladder spasm per order |
| Cloudy/malodorous urine | Concentrated urine, infection, biofilm | Increase fluids if appropriate; specimen for C&S per order; notify MD if fever or symptoms |
| Blood-tinged urine | Trauma during insertion, UTI, bladder cancer, anticoagulation | Assess degree; frank hematuria = notify MD; small amount post-insertion = monitor |
| Patient unable to void after removal | Urinary retention, residual bladder atony | Bladder scan for PVR; straight cath if >300–400 mL; restart Foley if persistent |
Removal Criteria & Technique
Remove the Catheter When:
- Clinical indication no longer present
- Post-operative period complete (most non-urologic surgeries)
- Patient is mobile enough to use bedpan/urinal or ambulate to bathroom
- Patient can void adequately without catheter (post-void residual <150–200 mL)
Removal Technique
- Explain procedure to patient
- Use clean gloves
- Attach syringe to balloon port; allow water to drain back passively (do NOT aspirate forcefully)
- Confirm all 10 mL (or specified amount) has returned before removing
- Ask patient to take a deep breath; gently withdraw catheter while patient exhales
- Document time of removal and time of first void
- If no void within 6–8 hours: bladder scan; notify MD if >300–400 mL retained
NCLEX High-Yield Points
- CAUTIs are the most common hospital-acquired infection; prevention = early removal
- Never disconnect the closed drainage system; use sample port for specimens
- Drainage bag must ALWAYS be below bladder level
- Inflate balloon only after urine returns AND advance 1–2 more inches
- Resistance during balloon inflation = STOP; catheter may be in urethra
- Leaking around catheter: do NOT upsize — treat cause (spasm, constipation)
- Assess catheter necessity DAILY — document indication; remove as soon as possible
