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
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 D
Explanation
A. "The diaphragmatic nerve overdrives the rapid rhythm:" The phrenic (diaphragmatic) nerve controls the diaphragm for breathing and plays no role in cardiac rhythm regulation. It is unrelated to the autonomic control of heart rate or supraventricular tachycardia (SVT) management.
B. "Vagal stimulation decreases peripheral vascular resistance:" Vagal stimulation primarily affects the heart by decreasing the rate and conduction through the AV node. Its effect on vascular resistance is minimal, making this explanation inaccurate in the context of SVT treatment.
C. "The vagus nerve increases the heart rate, overdriving the rhythm:" The vagus nerve has a parasympathetic effect, slowing down the heart rate, not increasing it. Overdrive pacing is a different concept and not related to vagal maneuvers like carotid massage.
D. "The vagus nerve slows the heart rate": The carotid sinuses in the neck contain baroreceptors that are sensitive to pressure. Massaging these sinuses stimulates the vagus nerve to release acetylcholine, which in turn slows conduction through the AV node and may terminate episodes of SVT. This response demonstrates an accurate understanding of the purpose of the procedure.
Correct Answer is B
Explanation
A. Have blood drawn weekly to check for high magnesium levels: Lisinopril, an ACE inhibitor, does not significantly affect magnesium levels. Regular monitoring is more important for potassium and renal function (BUN/creatinine), especially in heart failure patients, not magnesium.
B. Avoid the use of salt substitutes in your diet: Lisinopril is an ACE inhibitor. ACE inhibitors can cause potassium retention by reducing the production of aldosterone. Many salt substitutes contain high amounts of potassium chloride and combining the two may lead to hyperkalemia. Patients should be instructed to avoid these substitutes unless approved by their provider.
C. Notify your physician if a headache develops: Headache is a relatively common and usually mild side effect of lisinopril. It does not typically warrant discontinuation or immediate provider notification unless it's severe or persistent with other symptoms like dizziness or visual changes.
D. Take your heart rate daily when on this medication: Lisinopril does not significantly affect heart rate. Monitoring blood pressure is more relevant, as ACE inhibitors are antihypertensives. Heart rate monitoring is more critical with beta blockers or calcium channel blockers.
