A 35-year-old patient presents with pulmonary hypertension and is diagnosed with right heart failure. What is the most likely cause of this condition?

Aortic regurgitation

Mitral regurgitation

Aortic stenosis

Tricuspid regurgitation

Answer and Explanation

The Correct Answer is D

Choice A rationale
Aortic regurgitation is a condition where the aortic valve doesn’t close tightly, causing blood to leak back into the left ventricle. This condition can lead to left heart failure but is not typically associated with right heart failure.
Choice B rationale
Mitral regurgitation is a disorder in which the mitral valve on the left side of the heart does not close properly. This condition can lead to left heart failure but is not typically associated with right heart failure.
Choice C rationale
Aortic stenosis is a narrowing of the aortic valve opening. This condition can lead to left heart failure but is not typically associated with right heart failure.
Choice D rationale
Tricuspid regurgitation is a disorder in which the heart’s tricuspid valve does not close properly, causing blood to flow backward into the right atrium. This condition can lead to right heart failure, especially when associated with pulmonary hypertension.

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. Atrial Flutter - Cardioversion B. Ventricular Tachycardia - Cardioversion C. Atrial Fibrillation - Cardioversion D. Ventricular Fibrillation - Defibrillation

Correct Answer is D

Explanation

Choice A rationale
Atrial Flutter is a type of arrhythmia where the atria beat regularly, but much faster than usual. The treatment for Atrial Flutter is typically medication, not cardioversion.
Choice B rationale
Ventricular Tachycardia is a fast, abnormal heart rate. It starts in your heart’s lower chambers, or ventricles. Ventricular Tachycardia is a serious condition and can be life-threatening. While cardioversion can be used in some cases, it is not the primary treatment.
Choice C rationale
Atrial Fibrillation is when the upper chambers of the heart (atria) beat irregularly. This causes the atria to twitch, leading to an abnormal heart rhythm. The treatment for Atrial Fibrillation is typically medication, not cardioversion.
Choice D rationale
Ventricular Fibrillation is a life-threatening heart rhythm that results in a rapid, erratic heartbeat. During Ventricular Fibrillation, the heart quivers and can’t pump any blood, causing cardiac arrest. The treatment for Ventricular Fibrillation is Defibrillation.
