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.

Answer and Explanation

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

Elevated levels of LDL (low-density lipoprotein) cholesterol are associated with an increased risk of coronary artery disease (CAD). LDL cholesterol is often referred to as "bad" cholesterol because it can contribute to the formation of plaque in the arteries, leading to narrowing and blockage of the arteries supplying the heart. This increases the risk of developing CAD and related complications such as heart attack and stroke.

On the other hand, HDL (high-density lipoprotein) cholesterol is often referred to as "good" cholesterol. HDL cholesterol helps remove excess cholesterol from the bloodstream and transport it back to the liver for processing and excretion. Higher levels of HDL cholesterol are associated with a decreased risk of CAD because it helps to prevent the accumulation of cholesterol on artery walls.

Therefore, understanding that increased LDL and decreased HDL levels increase the risk of coronary artery disease demonstrates a good understanding of the significance of cholesterol levels and their impact on cardiovascular health.

A. Explain that no food or drink is allowed for 4 hours before the stress test. B. Ask the client's visitor to bring some coffee from the cafeteria for the client. C. Make up a small breakfast tray from what is available on the unit. D. Offer hot tea or coffee only.

Correct Answer is A

Explanation

The best response by the nurse would be to explain that no food or drink is allowed for 4 hours before the stress test.

The reason for this restriction is that consuming food or drink can affect the accuracy of the cardiac stress test results. Eating or drinking can increase heart rate and blood pressure, potentially altering the test's interpretation. It is important for the client to have an empty stomach to ensure accurate test results.

Let's review the other options and explain why they are not the best responses:

Asking the client's visitor to bring some coffee from the cafeteria for the client: This option goes against the restriction of no food or drink before the stress test. It is important to adhere to the guidelines provided to ensure accurate test results.

Making up a small breakfast tray from what is available on the unit: Similarly, providing breakfast to the client goes against the restriction of no food before the stress test. The client should have an empty stomach for the test.

Offering hot tea or coffee only: While hot tea or coffee might be tempting for the client, it still violates the requirement of no food or drink before the stress test. The client should only be allowed to consume water during the fasting period.
