## 문제

A nurse is caring for a client with a newly implanted permanent pacemaker. Which nursing intervention is most important during the immediate postoperative period?

## 보기

1. Monitor the insertion site for signs of bleeding or hematoma formation **✔ 정답**
2. Encourage early ambulation to prevent complications
3. Teach the client about electromagnetic interference precautions
4. Schedule follow-up appointments with the cardiologist

**정답: 1**

## 해설

Monitoring the insertion site for bleeding or hematoma is the priority to prevent life-threatening complications like hemorrhage or lead dislodgement. Other interventions are important but less urgent in the immediate postoperative period.

Understanding the Immediate Postoperative Priority

After permanent pacemaker implantation, the immediate postoperative period carries the highest risk for local surgical complications. The generator pocket created in the subcutaneous tissue is highly vascular, and because pacemaker implantation is performed under fluoroscopy with a transvenous approach, there is a risk of injury to the subclavian vein or surrounding arteries during lead placement. The most time-sensitive threat to patient safety is pocket hematoma or active bleeding, which can lead to hemodynamic instability, increase the risk of infection, and potentially require surgical re-exploration [1].

Why Monitoring the Insertion Site Is the Most Important Intervention

The insertion site assessment directly addresses the highest-acuity complication in the immediate postoperative phase. A hematoma can form rapidly and, if large enough, can compress the generator pocket, compromise skin flap viability, and serve as a medium for bacterial growth. Early detection through frequent inspection and palpation of the site, along with monitoring of vital signs for signs of hypovolemia, is a critical nursing safety function. Evidence-based home self-management guidance emphasizes that wound care and recognition of abnormal signs at the insertion site are foundational skills, but these are built upon the initial inpatient assessment that rules out acute bleeding first [1].

Distinguishing Between Immediate and Later Priorities

The other options represent important aspects of care but are not the most important intervention during the immediate postoperative period. Encouraging early ambulation is generally restricted in the first hours post-procedure to allow for hemostasis at the venous access site and generator pocket; premature movement can precipitate bleeding. Teaching about electromagnetic interference precautions and scheduling follow-up appointments are essential components of discharge planning and long-term self-management, but they are addressed later in the hospital stay, once the patient is hemodynamically stable and the immediate surgical risks have passed [1]. The systematic evidence summary on home-based self-management confirms that patient education focuses on long-term device function and lifestyle adaptation, not on managing acute postoperative complications, which remain the nurse's direct responsibility in the immediate phase [1].References (research sources)

## 임상 시나리오

Immediate Post-Pacemaker CarePrioritizing Insertion Site Assessment
The highest priority is inspecting the generator pocket for bleeding or hematoma formation. A rapidly expanding hematoma can cause hemodynamic instability and requires immediate intervention.

Assess the site every 15 minutes for the first hour, then every 30 minutes for the next 2 hours. Monitor for a visible bulge, excessive bruising, or a feeling of tightness reported by the patient.

CautionKeep the patient on bed rest with the affected arm immobilized for the prescribed period to prevent lead dislodgement, which is a higher immediate risk than deconditioning from immobility.

## 핵심 개념

- **Pocket Hematoma** — A collection of blood within the pacemaker pocket, a common early complication that increases pain and risk of infection.
- **Permanent Pacemaker (PPM)** — An implanted cardiac device that delivers electrical impulses to regulate heart rhythm.
- **Electromagnetic Interference (EMI)** — Disruption of pacemaker function by external electromagnetic fields, requiring patient education on avoidance.
