The occupational health nurse is evaluating a patient who is 3 weeks post pacemaker insertion. Which nursing intervention is MOST appropriate at this time?

Assessing the incision for any redness, swelling, or discharge

Applying wet-to-dry dressings every 4 hours to the insertion site

Reinforcing the pressure dressing as needed

Encouraging range-of-motion exercises of the involved arm

Answer and Explanation

The Correct Answer is A

A. Assessing the incision for any redness, swelling, or discharge: At 3 weeks post pacemaker insertion, the wound should be well into the healing process. Monitoring for signs of infection—such as redness, swelling, or discharge—remains a top priority to identify delayed wound complications like infection or erosion.

B. Applying wet-to-dry dressings every 4 hours to the insertion site: Wet-to-dry dressings are used for debridement of open wounds with significant drainage and necrotic tissue, not for healing surgical incisions. By 3 weeks post-procedure, the site should be dry and closed; such dressing changes would be inappropriate and potentially increase risk of infection.

C. Reinforcing the pressure dressing as needed: Pressure dressings are typically used in the immediate post-operative period to control bleeding and are not maintained weeks after insertion. Reinforcing one at this stage would suggest poor wound healing or inappropriate post-op management.

D. Encouraging range-of-motion exercises of the involved arm: While regaining full range of motion is important after pacemaker insertion, it's usually initiated gradually. Gentle arm movement may be resumed after a few weeks but early aggressive range-of-motion exercises are discouraged immediately post-insertion to prevent lead dislodgement. At the 3-week mark, movement should be cautious and per the provider’s specific clearance.

Correct Answer is A

Explanation

A. ambulate in the hall 3 times daily without shortness of breath: This directly reflects improved tolerance to activity, the central focus of the nursing diagnosis. Being able to ambulate without dyspnea indicates better cardiac output and ventricular function, marking resolution of the identified problem.

B. have an increase in systolic blood pressure of 20 mmHg during activity: A rise in systolic pressure may occur with exertion, but it does not necessarily indicate improved activity tolerance. In fact, an exaggerated BP response could indicate the heart is working harder than it should to meet the demands, suggesting poor cardiovascular adaptation to exercise.

C. decrease weight from 150 lbs. (68.2 kg.) to 148 lbs. (67.3 kg.) in five days: A slight weight reduction may reflect decreased fluid retention, but this outcome is more relevant to volume status and fluid balance than to resolving activity intolerance specifically.

D. verbalize the signs and symptoms of worsening heart failure by discharge:
While important for client education and self-management, this outcome relates to knowledge rather than physical tolerance to activity. It does not directly measure resolution of activity intolerance.

A. Edema of ankles B. Shortness of breath C. Fatigue after exercise D. Abdominal fullness

Correct Answer is B

Explanation

A. Edema of ankles: While peripheral edema may be associated with worsening cardiac function or side effects from other medications, it is not a hallmark adverse effect of amiodarone. It warrants evaluation but is not the most urgent symptom related to this drug.

B. Shortness of breath: Amiodarone is a potent antiarrhythmic medication with several potential serious side effects, including pulmonary toxicity. This can manifest as interstitial pneumonitis or pulmonary fibrosis, which may present as new or worsening shortness of breath cough, and chest pain. This is a potentially life-threatening complication and requires immediate medical attention.

C. Fatigue after exercise: Exercise-induced fatigue can result from many conditions, including heart disease or deconditioning, but it is a nonspecific symptom. It does not point directly to a serious adverse reaction from amiodarone.

D. Abdominal fullness: Abdominal fullness is not typically associated with amiodarone. It may relate to gastrointestinal or hepatic issues, but it is not as immediately concerning as respiratory symptoms suggestive of pulmonary toxicity.
