A patient who had a myocardial infarction asks the nurse why they are receiving morphine.
Which benefits of morphine should the nurse explain to this patient? (Select all that apply)

Choice A rationale:

Incorrect. Scarring on the atria is not an indication of procedure failure in the context of the maze procedure. In fact, it's a desired outcome.

Pacemaker implantation: Not routinely indicated after the maze procedure, even if scarring is present. Pacemakers are primarily used to treat bradyarrhythmias (slow heart rhythms), not atrial fibrillation.

Choice B rationale:

Incorrect. Repeating the maze procedure is generally not considered unless there's clear evidence of recurrent atrial fibrillation despite initial scarring. Scarring formation takes time, and premature repeat procedures are often not necessary.

Consulting the care team: While collaboration is essential, consultation specifically for repeating the procedure based solely on scarring would be premature.

Choice C rationale:

Correct. The maze procedure intentionally creates scar tissue within the atria to block abnormal electrical signals that cause atrial fibrillation. Scarring disrupts the pathways that allow these signals to circulate and trigger fibrillation. Therefore, the presence of scarring is a positive finding that suggests the procedure has achieved its intended effect.

Choice D rationale:

Incorrect. Further diagnostic testing is not routinely indicated solely based on the presence of scarring after the maze procedure. Additional testing might be considered if the patient experiences recurrent atrial fibrillation or other concerning symptoms, but scarring itself does not necessitate immediate further investigation.

Rationale for Choice A:

Monitoring the insertion site for hematoma and bleeding is crucial following cardiac angiogram with stent placement. Here's a detailed explanation:

Vascular Injury: The procedure involves accessing a major artery, usually the femoral artery in the groin. This creates a risk of bleeding or hematoma formation at the puncture site.

Anticoagulation: Patients often receive anticoagulant medications during and after the procedure to prevent blood clots from forming around the stent. These medications can increase the risk of bleeding.

Early Detection and Intervention: Prompt identification of bleeding or hematoma formation is essential to prevent complications such as hypotension, shock, or compartment syndrome.

Assessment: Regular assessment of the insertion site includes:

Visual inspection for swelling, bruising, or active bleeding.

Palpation for tenderness, firmness, or expanding hematoma.

Monitoring vital signs for tachycardia, hypotension, or signs of shock.

Interventions: If bleeding or hematoma is detected:

Apply direct pressure to the site.

Notify the healthcare provider immediately.

Implement additional measures as prescribed, such as reversal of anticoagulation or surgical intervention.

Rationale for Choice B:

Maintaining strict bedrest after cardiac angiogram with stent placement is no longer routinely recommended. Here's why:

Early Ambulation Benefits: Research has shown that early ambulation (usually within 6-8 hours) is associated with several benefits, including:

Reduced risk of deep vein thrombosis (DVT)

Improved circulation

Quicker recovery

Shorter hospital stays

Individualized Assessment: The decision regarding ambulation timing should be individualized based on patient factors such as:

Bleeding risk

Procedural complications

Overall health status

Comfort level

Balanced Approach: While early ambulation is encouraged, it's important to balance activity with rest to promote healing and prevent complications.

Rationale for Choice C:

Monitoring for dysrhythmias is essential following cardiac angiogram with stent placement due to several reasons:

Cardiac Irritation: The procedure involves manipulation of catheters and devices within the heart, which can potentially irritate the heart's electrical system.

Electrolyte Imbalances: Contrast dye used during the procedure can cause electrolyte imbalances, which can also trigger dysrhythmias.

Underlying Heart Disease: Patients undergoing angioplasty often have underlying heart disease, which already predisposes them to rhythm disturbances.

Early Detection and Intervention: Prompt identification of dysrhythmias allows for timely interventions to prevent hemodynamic instability, heart failure, or cardiac arrest.

Continuous Monitoring: Continuous ECG monitoring is typically used to detect dysrhythmias, and patients are closely observed for symptoms such as palpitations, lightheadedness, or chest pain.

Rationale for Choice D:

Assessing heart sounds is a crucial nursing intervention following cardiac angiogram with stent placement. Here's why:

Stent Placement Effects: The placement of a stent can alter blood flow patterns within the coronary arteries, which may be audible as changes in heart sounds.

Complication Detection: Heart sounds can provide valuable clues about potential complications such as:

Pericardial effusion (fluid around the heart)

Myocardial infarction (heart attack)

Valvular dysfunction

Baseline Assessment: It's important to establish a baseline assessment of heart sounds prior to the procedure to compare with post-procedure findings.

Regular Auscultation: Regular auscultation of heart sounds should be performed to monitor for changes and promptly report any concerns to the healthcare provider.
