After pacemaker placement, which of the following is a common nursing concern in the immediate postoperative period?

• A. Lead displacement or device malfunction.
• B. Hyperglycemia.
• C. Renal failure.
• D. Gastrointestinal bleeding.

Answer: (A)

The main concept is ensuring the pacemaker system is functioning properly right after placement. In the immediate postoperative period, the most common nursing concern is lead displacement or device malfunction. The leads are delicate as the body heals the pocket, and movement, coughing, or stretching of the arm on the operative side can cause the leads to shift or for the generator to fail to capture or sense correctly. If a lead moves or the device malfunctions, the heart may not be paced when needed, leading to bradycardia, dizziness, hypotension, or syncope.

Nursing actions focus on detecting battery or sensing/pacing problems early. This includes closely monitoring the heart rhythm and the patient’s vital signs, assessing for symptoms like lightheadedness, chest discomfort, or fatigue, and confirming that the device is pacing as intended. Device interrogation by the care team and a chest radiograph are typically obtained to confirm lead position and function. Also, inspect the incision for hematoma or infection, restrict vigorous movement of the affected arm for several weeks, and educate the patient to avoid strong magnetic fields and to report any changes in heart rhythm or symptoms promptly.

Hyperglycemia, renal failure, and gastrointestinal bleeding are not specific, common postoperative concerns tied to the pacemaker itself in the immediate period after placement. They can occur with many surgeries but do not focus on the pacemaker system the way lead displacement or device malfunction do.
