A nurse recalls that systolic heart failure results in which of the following intraventricular hemodynamic changes?

Increased left ventricular preload.

Increased ejection fraction.

Decreased right ventricular preload.

Decreased right ventricular end-diastolic pressure.

Answer and Explanation

The Correct Answer is A

Choice A rationale:

Systolic heart failure results in increased left ventricular preload. In systolic heart failure, the heart's ability to contract and eject blood effectively is impaired. This leads to decreased ejection fraction, which means that a significant amount of blood is left in the left ventricle at the end of systole. This increased volume of blood in the left ventricle during diastole is referred to as "preload.”. The increased preload is a compensatory mechanism that the heart uses to maintain cardiac output. However, over time, this increased preload can lead to symptoms of congestion and fluid overload.

Choice B rationale:

Systolic heart failure is characterized by decreased ejection fraction, not increased. Ejection fraction is a measure of the percentage of blood ejected from the left ventricle with each heartbeat. In systolic heart failure, this percentage is reduced.

Choice C rationale:

Systolic heart failure does not directly affect right ventricular preload. Right ventricular preload is more related to conditions that affect the right side of the heart, such as pulmonary hypertension.

Choice D rationale:

Systolic heart failure does not necessarily result in decreased right ventricular end-diastolic pressure. Right ventricular end-diastolic pressure can be influenced by a variety of factors, and its alteration is not a specific hallmark of systolic heart failure.

Correct Answer is A

Explanation

Choice A rationale:

Mitral valve prolapse is an autosomal dominant condition. If a patient's history indicates that cardiac valve disease is autosomal dominant, the nurse is likely to find a diagnosis of mitral valve prolapse in the patient's chart. Mitral valve prolapse is a condition where the mitral valve doesn't close properly, allowing blood to flow back into the left atrium.

Choice B rationale:

Pulmonary stenosis is not typically associated with autosomal dominant inheritance. It's more commonly associated with sporadic genetic mutations or other non-genetic factors.

Choice C rationale:

Tricuspid regurgitation is not usually an autosomal dominant condition. Like pulmonary stenosis, it's often caused by other factors rather than being directly related to genetic inheritance.

Choice D rationale:

Aortic stenosis is not typically an autosomal dominant condition. It's more commonly related to age-related degeneration or other non-genetic factors.

A. Infective endocarditis is most often caused by:. B. Viruses. C. Bacteria. D. Fungi. E. Autoimmunity.

Correct Answer is C

Explanation

Choice A rationale:

Infective endocarditis is most often caused by bacteria. This condition occurs when bacteria enter the bloodstream and adhere to the inner lining of the heart's chambers or valves, leading to infection. Viruses, fungi, and autoimmunity can also cause endocarditis, but bacterial endocarditis is the most common and typical form.

Choice B rationale:

While viruses can cause infective endocarditis, they are not the most common cause. Bacterial endocarditis is far more prevalent and frequently encountered in clinical practice.

Choice D rationale:

Fungi can cause endocarditis, but it is less common compared to bacterial endocarditis. Fungal endocarditis often occurs in individuals with compromised immune systems.

Choice E rationale:

Autoimmunity is not a primary cause of infective endocarditis. Autoimmune diseases may lead to various cardiac conditions, but they are not the primary etiology of infective endocarditis.
