The nurse is reviewing the medical records of a client with atrial fibrillation. Which prescription should the nurse question?
Obtain consent for transesophageal echocardiogram (TEE)
Obtain consent for a STAT defibrillation
Obtain consent for cardioversion.
Hold digoxin 48 hours prior to cardioversion.
The Correct Answer is B
Defibrillation is not the first-line treatment for atrial fibrillation. It is used to treat life-threatening cardiac arrhythmias such as ventricular fibrillation or pulseless ventricular tachycardia. Atrial fibrillation, on the other hand, is a rapid and irregular atrial rhythm, and defibrillation is not indicated for its treatment.
Obtain consent for transesophageal echocardiogram (TEE): This is an appropriate action for a client with atrial fibrillation. A TEE is often performed to assess the structure and function of the heart in cases of atrial fibrillation, especially when considering cardioversion or other interventions.
Obtain consent for cardioversion: Cardioversion is a common treatment option for atrial fibrillation, especially when the client is unstable or experiencing symptoms. It involves restoring a normal heart rhythm through the use of electrical shocks or medications. It is important to obtain informed consent before performing cardioversion, but this does not necessarily require questioning.
Hold digoxin 48 hours prior to cardioversion: Digoxin is commonly held before cardioversion because it can increase the risk of certain arrhythmias during the procedure. This is a standard precaution to minimize potential adverse effects. Therefore, the nurse does not need to question this action, as it aligns with established guidelines.

Correct Answer is A
Explanation
The nurse should teach the client that the transthoracic echocardiography is a noninvasive test and that nothing will be inserted into the client's body.
Transthoracic echocardiography is a diagnostic procedure that uses ultrasound to create images of the heart's structures and assess its function. It is a noninvasive test, meaning that it does not involve any insertion of instruments or devices into the body. Instead, a transducer is placed on the chest to obtain images of the heart.
The statement about managing pain aggressively during the procedure is not applicable to transthoracic echocardiography. It is generally a painless procedure that does not cause discomfort.
Transthoracic echocardiography primarily provides detailed images of the heart's structures and function, such as the chambers, valves, and pumping action. It does not specifically profile the heart's electrical activity, which is usually assessed using an electrocardiogram (ECG) or other specialized tests.
Regarding bed rest after the test, there is typically no need for bed rest following transthoracic echocardiography. The client can usually resume normal activities immediately after the procedure. However, the nurse should provide specific instructions based on the client's condition and any additional tests or interventions planned.

Correct Answer is B
Explanation
The nurse should best follow up the assessment finding of an ankle-brachial index (ABI) of 0.40 in the right leg by implementing interventions relevant to arterial narrowing.
An ankle-brachial index is a non-invasive test used to assess peripheral arterial disease (PAD). An ABI value below 0.90 indicates significant arterial narrowing and impaired blood flow to the lower extremities. An ABI of 0.40 suggests severe arterial narrowing, which puts the client at risk for reduced perfusion and potential complications such as tissue ischemia, ulceration, and gangrene.
Implementing interventions relevant to arterial narrowing is crucial in this case. These interventions may include:
- Collaborating with the healthcare provider to develop a treatment plan: This may involve prescribing medications to improve blood flow, such as antiplatelet agents or vasodilators.
- Encouraging lifestyle modifications: This can include smoking cessation, regular exercise, and maintaining a healthy diet low in saturated fats and high in fruits and vegetables.
- Promoting optimal cardiovascular health: This can involve managing other risk factors for arterial narrowing, such as hypertension, diabetes, and high cholesterol levels.
- Educating the client about the signs and symptoms of PAD: This includes teaching them to monitor for changes in skin color, temperature, and sensation in the affected limb, as well as the importance of seeking prompt medical attention if these changes occur.

Let's review the other options:
Assessing the client's use of over-the-counter dietary supplements: While it is important to assess for potential interactions between medications and dietary supplements, this would not be the immediate follow-up action for a severely reduced ABI.
Encouraging the client to increase intake of foods high in vitamin K: While maintaining a balanced diet is important for overall health, increasing vitamin K intake is not specifically indicated for addressing arterial narrowing or improving the ABI.
Adjusting the client's activity level to accommodate decreased coronary output:
Coronary output refers to blood flow to the heart muscle. Arterial narrowing in the leg does not directly affect coronary output. However, it is important to encourage appropriate physical activity for the client based on their overall cardiovascular health and exercise tolerance.
