A patient with dilated cardiomyopathy has recently developed atrial fibrillation that has been unresponsive to drug therapy for several days.

What topic should the nurse plan to include in patient teaching?

Adenosine (Adenocard).

Emergency cardioversion.

Anticoagulant therapy.

Permanent pacemakers.

Answer and Explanation

The Correct Answer is C

Choice A rationale
Adenosine (Adenocard) is a medication that can be used to treat supraventricular tachycardia, a type of abnormal heart rhythm. However, it is not typically used for atrial fibrillation.
Choice B rationale
Emergency cardioversion, where an electric shock is used to restore the heart’s normal rhythm, can be used in some cases of atrial fibrillation. However, if the atrial fibrillation has been present for more than 48 hours, there is a risk of blood clots, and anticoagulation for several weeks before the procedure may be needed.
Choice C rationale
Anticoagulant therapy is often used in patients with atrial fibrillation to reduce the risk of stroke. Atrial fibrillation can lead to blood pooling in the atria, increasing the risk of clot formation. These clots can then travel to the brain, causing a stroke.
Choice D rationale
Permanent pacemakers are sometimes used in atrial fibrillation to help regulate the heart’s rhythm. However, they are typically used when other treatments have failed or are contraindicated.

Correct Answer is A

Explanation

Choice A rationale
Tetralogy of Fallot is a congenital heart condition that presents with a combination of four defects in the structure of the heart. The most common symptoms in a newborn with this condition include cyanosis (bluish color of the skin due to reduced oxygen in the blood) and hypoxia (low levels of oxygen in the body)34567.
Choice B rationale
While a high-pitched cry can be a sign of distress in a newborn, it is not specifically associated with tetralogy of Fallot. Dyspnea (difficulty breathing) can occur in severe cases, but it is not one of the primary symptoms of this condition.
Choice C rationale
Leg pain and twitching are not typical symptoms of tetralogy of Fallot. These symptoms could be indicative of other conditions, but they are not associated with this specific congenital heart defect.
Choice D rationale
Epistaxis (nosebleeds) and anemia are not typical symptoms of tetralogy of Fallot. While these conditions can occur in children for various reasons, they are not directly related to this specific congenital heart defect.

A. Intermittent claudication and pallor. B. Jugular vein distention and dependent edema. C. Mid-epigastric pain and heartburn. D. Sweating and cool, clammy skin.

Correct Answer is D

Explanation

Choice A rationale
Intermittent claudication and pallor are not typically symptoms of a myocardial infarction. Intermittent claudication, or pain in the legs with exercise, is more commonly associated with peripheral artery disease. Pallor, or paleness, can occur with various conditions but is not a specific sign of myocardial infarction3.
Choice B rationale
Jugular vein distention and dependent edema are not typically symptoms of a myocardial infarction. These signs are more commonly associated with heart failure3.
Choice C rationale
Mid-epigastric pain and heartburn can sometimes be symptoms of a myocardial infarction, particularly in women. However, these symptoms can also occur with many other conditions, including gastrointestinal disorders3.
Choice D rationale
Sweating and cool, clammy skin are common symptoms of a myocardial infarction. These symptoms occur due to the body’s stress response to the decreased blood flow to the heart muscle3.
