A nurse is caring for a client with severe aortic stenosis who is scheduled for balloon valvuloplasty. Which nursing intervention is most important to implement in the immediate postprocedure period?

해설
Monitoring the catheter insertion site is the priority to prevent life-threatening hemorrhage post-valvuloplasty. Other interventions like anticoagulants or heart sound assessment are important but not immediate priorities.

Core Nursing Explanation Key Concept Analysis: This question tests the priority nursing intervention following a balloon valvuloplasty, a minimally invasive procedure to widen a stenotic (narrowed) heart valve. The core theme is post-procedure safety and complication prevention. For any procedure involving arterial catheterization (like accessing the femoral artery), the most immediate and potentially life-threatening risk is Key Point! hemorrhage from the vascular access site.

Answer Rationale: Option ③ is correct because it directly addresses the primary safety concern. After the catheter is removed, the insertion site (often the femoral artery) is manually compressed and then a pressure dressing is applied. Vigilant monitoring for signs of bleeding (oozing, expanding hematoma, hypotension, tachycardia) is the Key Point! immediate priority in the post-procedure period to prevent hypovolemic shock. This aligns with the nursing process principle of addressing actual threats to physiological integrity (Airway, Breathing, Circulation) first.

Distractor Analysis:
Watch out for confusion! Option ① (Encourage early ambulation) is incorrect and dangerous. After arterial access, the patient is typically on strict bed rest with the affected leg immobilized for several hours (e.g., 4-6 hours) to ensure hemostasis and prevent dislodgment of the clot at the puncture site. Early ambulation increases the risk of bleeding.
Option ② (Administer prescribed anticoagulants) is important for preventing thrombus formation on the newly treated valve or at the catheter site, but it is not the most important immediate intervention. In fact, anticoagulation increases the bleeding risk, making site monitoring even more critical. Administration follows a specific protocol and is not the first action upon patient arrival.
Option ④ (Assess heart sounds) is a valuable assessment to evaluate the procedural success (a softer murmur indicates improved valve opening), but it is a secondary priority. Physiological stability (preventing hemorrhage) must be ensured before conducting evaluative assessments.

Related Concepts: The priority of monitoring for bleeding applies to many post-catheterization procedures (cardiac catheterization, coronary angioplasty, etc.). Understanding aortic stenosis pathophysiology (left ventricular hypertrophy, reduced cardiac output) is key to pre-procedure care, but post-procedure care focuses on universal procedural complications. Concept Summary
ConceptKey Points
Balloon ValvuloplastyMinimally invasive procedure to dilate a stenotic heart valve using a balloon-tipped catheter. Access is typically via the femoral artery.
Post-Procedure PriorityABCs (Airway, Breathing, Circulation). For arterial procedures, Circulation threat = hemorrhage from access site.
Critical Nursing Interventions1. Monitor insertion site (bleeding, hematoma, pulse distal to site).
2. Maintain bed rest with leg immobilization.
3. Monitor vital signs (VS) for hypotension/tachycardia.
4. Assess neurovascular status of the affected limb.
Potential ComplicationsBleeding/hematoma, retroperitoneal hemorrhage, arterial occlusion, embolism, arrhythmias, valve regurgitation (new or worsened).

Major ComplicationHemorrhage, arterial dissectionCardiac tamponade, hemorrhage, infection
Anatomy, Physiology & Pharmacology Points Anatomy: The procedure accesses the aortic valve via retrograde catheterization from the femoral artery → iliac artery → aorta.
Pathophysiology: Aortic stenosis causes left ventricular pressure overload and hypertrophy, leading to symptoms like angina, syncope, and heart failure.
Pharmacology: Patients are often on antiplatelets (e.g., aspirin) or anticoagulants (e.g., heparin during procedure). Post-procedure, antiplatelet therapy is common to prevent thrombosis at the treatment site. Memory Tips Mnemonic: "SITE Comes First" for post-catheterization priorities:
Site monitoring (for bleeding)
Immobilize the limb
Thrombosis prevention (meds later)
Evaluate distal pulses
Always remember: Bleeding kills faster than a murmur. Safety before assessment. High-Frequency NCLEX Topics This question tests priority-setting (Maslow's Hierarchy, ABCs) and complication prevention for common procedures. The NCLEX loves to present post-procedure scenarios and ask, "What is the nurse's priority action?" The answer almost always involves direct patient safety (bleeding, airway, fall risk) over evaluative or educational tasks. Watch Out for Question Variations! * Instead of asking for the priority intervention, it might ask: "Which finding requires immediate intervention?" (Answer: "A rapidly expanding hematoma at the femoral site" or "Loss of pedal pulse.")
* The scenario could shift to a patient on anticoagulants (e.g., warfarin), making bleeding risk even higher and site monitoring the absolute priority.
* It could be combined with symptom management for aortic stenosis (e.g., managing angina, syncope precautions) in the pre-prophase.

임상 시나리오

Nursing Clinical Practice Guide Clinical Scenario: You receive Mr. Johnson, a 72-year-old with severe aortic stenosis, in the cardiac recovery unit post-balloon valvuloplasty. The femoral sheath was removed 30 minutes ago, and a pressure dressing is in place. He is awake and alert.

Nursing Intervention Strategy: 1. Immediate Assessment (First 15 mins): Introduce yourself. Check the pressure dressing for any visible bleeding. Palpate the area gently for swelling or a pulsatile mass (sign of hematoma). Compare the warmth, color, and capillary refill of both feet. Assess the dorsalis pedis and posterior tibial pulses bilaterally using a Doppler if needed. Take vital signs (BP, HR, O2 sat). 2. Ongoing Monitoring & Care: Enforce bed rest with the affected leg kept straight. Reassess the site, pulses, and VS per protocol (e.g., every 15 min x 4, then every 30 min x 2, then hourly). Monitor for signs of covert bleeding: dropping BP (< 90/60), rising HR (> 100), pallor, restlessness, or back/flank pain (suggesting retroperitoneal hemorrhage). 3. Patient Education: Explain the importance of lying flat and not bending the hip. Instruct the patient to report any sensation of warmth or wetness at the groin, sudden pain, or dizziness immediately.

Patient Safety and Precautions: * Contraindication: Do not elevate the HOB (Head of Bed) significantly until the prescribed bed rest time is complete (usually 4-6 hours). Do not allow the patient to sit up or use a bedpan that requires hip flexion. * Medication Caution: If anticoagulants (e.g., heparin drip) are ordered, double-check the dosage and infusion rate with another nurse. The bleeding risk is compounded. * Key Monitoring: A sudden loss of the distal pulse is an emergency indicating arterial occlusion. A rapidly expanding, firm hematoma may require manual re-compression or surgical intervention. Nursing Procedure & Medication Flow Post-Valvuloplasty Site Care: 1. Verify physician's orders for sheath removal time, bed rest duration, and anticoagulation plan. 2. Upon patient arrival, perform baseline neurovascular assessment of both lower extremities. 3. Maintain strict aseptic technique when inspecting or redressing the site. 4. If bleeding occurs: Apply direct, firm pressure 1-2 inches above the puncture site (to compress the artery against the bone) and call for help. Do not release pressure until a provider assesses. 5. Document: Site appearance, size of any hematoma, presence/strength of distal pulses, capillary refill, patient's response, and all VS trends. A Word from Your Senior Nurse "In the controlled chaos of a recovery unit, it's easy to get distracted by monitors and orders. But for this patient, your most important tool is your own eyes and hands on that groin site. I've seen a 'stable' patient become hypotensive in minutes from a hidden bleed. Your vigilant, hands-on assessment is what stands between a routine recovery and a crisis. On the NCLEX and in real life, never forget: Safety first, assessment second, everything else follows."
