A 72-year-old male with benign prostatic hyperplasia (BPH) is scheduled for a transurethral resection of the prostate (TURP). Which preoperative nursing intervention is most important to prevent postoperative complications?

Ensuring adequate hydration and monitoring electrolyte balance preoperatively helps prevent TURP syndrome, a life-threatening complication. Other interventions are beneficial but less critical for preventing this specific complication.

Core Nursing Explanation Key Concept Analysis: This question assesses the critical preoperative nursing priority for a patient undergoing Transurethral Resection of the Prostate (TURP). The core theme is preventing TURP syndrome, a potentially fatal complication unique to this procedure. During TURP, the surgeon uses a non-electrolytic irrigation fluid (like glycine or sorbitol) to maintain a clear visual field. This fluid can be absorbed into the patient's systemic circulation through open prostatic veins, leading to fluid overload, dilutional hyponatremia, and neurological symptoms.

Answer Rationale: Key Point! The most important preoperative intervention is Ensuring adequate hydration and monitoring electrolyte balance. Why? Proper hydration helps establish a stable baseline for the patient's fluid and electrolyte status. This allows for more accurate intraoperative and postoperative monitoring and management. If the patient is already dehydrated or has electrolyte imbalances preoperatively, they are at a much higher risk for severe complications from the fluid shifts and dilution that occur during TURP. Preoperative optimization is a proactive, preventative measure.

Distractor Analysis: Watch out for confusion! While all options are valid preoperative nursing actions, they address different risks. Prophylactic antibiotics (Option 1) are important for preventing infection, which is a common postoperative concern but not the most life-threatening immediate complication of TURP. Teaching deep breathing and coughing exercises (Option 3) is a standard preoperative teaching for many surgeries to prevent atelectasis and pneumonia, but it is not specific to the unique risks of TURP. Applying sequential compression devices (Option 4) is crucial for preventing deep vein thrombosis (DVT) in immobilized patients, but it is typically initiated postoperatively, not preoperatively, and is not the primary defense against TURP syndrome.

Related Concepts: Understanding TURP syndrome is paramount. Symptoms include hypertension, bradycardia, confusion, nausea, and visual disturbances due to cerebral edema from hyponatremia. Postoperative nursing care focuses on monitoring for these signs, managing a continuous bladder irrigation (CBI) system to prevent clot retention, and ensuring catheter patency.

Concept Summary

Concept	Description	Nursing Implication
TURP Syndrome	Life-threatening complication from absorption of irrigation fluid, causing fluid overload and hyponatremia.	Monitor for symptoms (confusion, bradycardia, hypertension). Pre-op: Hydrate. Intra/Post-op: Strict I&O, monitor electrolytes (especially Na+).
Continuous Bladder Irrigation (CBI)	Post-op system to flush clots from the bladder via a 3-way Foley catheter.	Ensure system is patent and flowing. Monitor output for color (should be light pink to clear) and for clots.
Clot Retention	Blockage of the urinary catheter by blood clots, a common post-TURP complication.	Maintain CBI flow rate. If output stops, irrigate catheter per protocol to restore patency.

Anatomy, Physiology & Pharmacology Points

• Pathophysiology: BPH causes enlargement of the prostate gland, obstructing urine flow. TURP removes this tissue from inside the prostate capsule.
• Irrigation Fluid: Non-electrolytic fluids (e.g., glycine 1.5%) are used because they are non-conductive, allowing electrocautery to work. Their absorption dilutes serum sodium.
• Lab Value: Monitor for Hyponatremia (Na+ < 135 mEq/L). Normal serum sodium is 135-145 mEq/L.

Memory Tips

• Acronym: Think "Hydrate for Hyponatremia" – the key pre-op action for TURP.
• Association: TURP = "Too Much Fluid in the Wrong Place." The priority is managing that fluid risk from the start.

High-Frequency NCLEX Topics TURP and its complications are classic NCLEX subjects. Expect questions on:

1. Identifying signs of TURP syndrome (neurological changes + vital sign changes).
2. Priority nursing actions for a patient with a continuous bladder irrigation (e.g., "If the drainage is bright red with clots, the nurse should...").
3. Differentiating expected post-TURP findings (pink-tinged urine) from complications (bright red bleeding, no urine output).

Watch Out for Question Variations!

• Symptom Identification: "A client 2 hours post-TURP is confused and has a blood pressure of 170/90 mmHg. The nurse should suspect..." (Answer: TURP syndrome).
• Priority Intervention: "The nurse is caring for a client with continuous bladder irrigation post-TURP. The drainage bag is empty. What should the nurse do first?" (Answer: Check for kinks in the tubing and irrigate the catheter to restore patency—addressing clot retention is the priority).
• Patient Teaching: "Which instruction is most important for a client being discharged after TURP?" (Answer: Avoid straining, heavy lifting, and driving for several weeks to prevent hemorrhage).

Nursing Clinical Practice Guide Clinical Scenario: Mr. Johnson, 72, is on your surgical unit the night before his scheduled TURP for symptomatic BPH. He has a history of mild hypertension. During your assessment, he mentions he didn't drink much today because he was nervous about the surgery and didn't want to "be up all night going to the bathroom."

Nursing Intervention Strategy:

1. Assessment: Review his admission labs (especially sodium, BUN, creatinine). Perform a focused assessment on his current hydration status (skin turgor, mucous membranes, urine output). Ask about his usual fluid intake.
2. Planning & Implementation: Your priority is to correct his mild dehydration preoperatively.
   • Educate him on the importance of hydration to prevent serious complications after surgery. Encourage him to drink clear fluids up until the NPO time (e.g., midnight).
   • Collaborate with the provider to possibly initiate IV fluids overnight if oral intake is insufficient.
   • Document baseline vital signs and neurological status meticulously for postoperative comparison.
3. Patient Education: Explain what TURP syndrome is in simple terms: "Sometimes during this surgery, the cleaning fluid can get into your bloodstream and cause an imbalance. Making sure you're well-hydrated beforehand helps your body handle that better." Also teach about the post-op catheter and CBI.

Patient Safety and Precautions: The major safety threat is unrecognized TURP syndrome. Postoperatively, monitor intake and output (I&O) meticulously—the output should equal or exceed the irrigation fluid input. A sudden change in mental status (agitation, confusion, lethargy) is a red flag requiring immediate notification of the surgeon and stat electrolyte checks.

Nursing Procedure & Medication Flow Managing Continuous Bladder Irrigation (CBI):

1. Setup: A 3-way Foley catheter is placed. One port drains urine, one inflates the balloon, and the third is for irrigation fluid inflow.
2. Monitoring: The irrigation fluid (usually normal saline post-op) runs by gravity. Monitor the color of the outflow: it should be light pink ("vin rosé") and without large clots.
3. Troubleshooting: If outflow stops or is bright red:
   • Check for kinks.
   • Gently irrigate the catheter with 30-50 mL of sterile irrigation solution using a piston syringe to dislodge a possible clot.
   • If patency isn't restored, notify the provider immediately—this is clot retention.
4. I&O Calculation: True urine output = Total drainage from catheter bag MINUS Volume of irrigation fluid infused. This must be calculated hourly initially.

A Word from Your Senior Nurse "Nursing is not just about carrying out physician orders — it's about being the frontline guardian for your patients! With a TURP patient, you are the one who will notice the subtle shift from 'a little sleepy' to 'lethargic and confused.' That's the difference between catching TURP syndrome early and managing it versus dealing with a full-blown crisis. Your preoperative action of ensuring hydration sets the stage for a safer surgery. In clinical practice and on the NCLEX, always ask yourself: 'What is the unique, life-threatening risk for THIS specific procedure?' That's where you'll find your priority nursing intervention."
