Question

The client returns to the intensive care unit following a coronary artery bypass graft. The nurse notes that the client is suddenly experiencing shortness of breath with muffled heart sounds. The blood pressure is \(90 / 40\), and the pulse rate is 110 beats per minute. Which action is most appropriate initially? A. Check the mediastinal tube for drainage B. Recheck the vital signs C. Administer pain medication D. Decrease the intravenous flow rate

Short answer

Answer: Check the mediastinal tube for drainage.

Step-by-step solution

Understand the scenario

The client has a recently undergone a coronary artery bypass graft. They are now experiencing shortness of breath, muffled heart sounds, a blood pressure of \(90 / 40\), and a pulse rate of 110 beats per minute.

Analyze the symptoms

The symptoms provided are indicative of as issue that may require immediate action. Shortness of breath and muffled heart sounds are particularly concerning.

Review the options

We have four options to select from: A. Check the mediastinal tube for drainage B. Recheck the vital signs C. Administer pain medication D. Decrease the intravenous flow rate

Evaluate the options

Let's analyze each option: A. Checking the mediastinal tube may provide useful information, but it may not be the most critical initial action considering the severity of the patient's condition. B. Rechecking the vital signs may give us updated information, but the urgency of the situation suggests a more appropriate initial action is necessary. C. Administering pain medication may relieve some of the patient's discomfort, but it may not address the underlying issue causing these severe symptoms. D. Decreasing the intravenous flow rate may help if there is too much fluid being administered, but it may not be the most appropriate initial step in this scenario.

Choose the most appropriate initial action

Based on our evaluation of the options, the most appropriate initial action is: A. Check the mediastinal tube for drainage The rationale for this choice is that it may provide crucial information about the patient's condition and help identify underlying issues that could be causing the symptoms, allowing for more specific and targeted treatment.

Key concepts

Coronary Artery Bypass Graft

A Coronary Artery Bypass Graft (CABG) is a surgical procedure used to treat coronary artery disease. This procedure involves taking a blood vessel from another part of the body and attaching it to the coronary artery above and below the narrowed area or blockage. This new pathway for blood flow is called a graft. CABG can relieve chest pain, improve the patient’s quality of life, and in some cases, prolong survival.

A key point of understanding CABG is recognizing the potential complications that can arise postoperatively. These complications include, but are not limited to, bleeding, infection, and cardiac tamponade, a severe condition where blood or fluid builds up between the heart muscle and the surrounding sac (pericardium). The symptoms presented in our exercise – shortness of breath, muffled heart sounds, and a low blood pressure – could suggest such a complication.

Nursing Care Postoperative

Nursing care postoperatively, especially after major surgery like CABG, is critical. It focuses on monitoring the patient for any signs of complications, managing pain, and promoting recovery. Initial postoperative care in the intensive care unit (ICU) involves vigilant monitoring of vital signs, heart sounds, and the patency of drainage tubes.

In the context of the exercise provided, where the patient is showing concerning symptoms post-CABG, the nurse’s duty includes:

• Checking for mediastinal tube drainage to ensure no blood accumulation is causing the symptoms.
• Assessing the patient’s pain and providing appropriate interventions.
• Managing intravenous fluids to avoid fluid overload, which could impact heart function.

Ongoing assessment and timely interventions can significantly influence the patient’s recovery process.

Critical Thinking in Nursing

Critical thinking in nursing is the ability to think in a systematic and logical manner with openness to questioning and reflect on the reasoning process used to ensure safe nursing practice and quality care. Nurses must integrate information from a variety of sources, including patient observations, diagnostic tests, and the patient’s health history.

In the exercise scenario, critical thinking is applied by considering the immediate symptoms, potential causes, and the most appropriate and urgent action required. The decision to first check the mediastinal tube for drainage is based on critical thinking. It prioritizes patient safety by addressing the potential life-threatening complication of cardiac tamponade before considering other interventions.

This approach involves the nurse drawing on in-depth knowledge of pathophysiology, the ability to assess patient signs and symptoms quickly, and the application of best practices to make informed decisions about patient care.
