A 73-year-old patient has increased pulmonary pressure resulting in right heart failure. What could be a potential cause for the right heart to fail?

Left heart failure.

Pericarditis.

Hypertension.

Acute pneumonia.

Answer and Explanation

The Correct Answer is A

Choice A rationale
Left heart failure is a common cause of right heart failure. When the left side of the heart is unable to pump blood efficiently, it can cause increased pressure in the lungs, which can then lead to right heart failure.
Choice B rationale
Pericarditis, an inflammation of the sac-like covering around the heart, is not typically a direct cause of right heart failure.
Choice C rationale
While hypertension, or high blood pressure, can contribute to heart failure, it typically affects the left side of the heart more than the right.
Choice D rationale
Acute pneumonia, an infection that inflames the air sacs in one or both lungs, is not typically a direct cause of right heart failure.

Correct Answer is D

Explanation

Choice A rationale
Sinus tachycardia at a rate of 110 beats/min is a normal response to exercise. During a stress test, the heart rate will naturally increase as the body’s demand for oxygen increases. A heart rate of 110 beats/min is within the expected range during moderate exercise.
Choice B rationale
An increase in blood pressure from 134/68 to 150/80 mm Hg is a normal response to exercise. During a stress test, blood pressure will naturally rise as the heart works harder to pump blood to the muscles. This increase is within the expected range during moderate exercise.
Choice C rationale
Feeling tired during a stress test on a treadmill is a normal response to exercise. Fatigue can occur as the body’s energy stores are used up during physical activity. However, if the patient reports extreme fatigue or other symptoms such as chest pain or shortness of breath, it may indicate a problem.
Choice D rationale
Inversion of T waves on the electrocardiogram during a stress test is a sign of myocardial ischemia, a condition in which the heart muscle is not getting enough oxygen. This could indicate the presence of significant coronary artery disease and is a finding that would necessitate immediate action.

A. Pulsus paradoxus. B. Exudate. C. Aneurysm. D. Tamponade.

Correct Answer is D

Explanation

Choice A rationale
Pulsus paradoxus, an exaggerated decrease in systolic blood pressure during inspiration, can be a sign of several conditions, including pericardial tamponade, constrictive pericarditis, and restrictive cardiomyopathy.
Choice B rationale
Exudate, a fluid with a high protein content that leaks out of blood vessels due to inflammation, is not typically associated with the symptoms described.
Choice C rationale
An aneurysm, a bulge or ballooning in a blood vessel, could potentially cause the symptoms described, but it is not the most concerning finding given the symptoms of edema, hepatomegaly, and muffled heart sounds.
Choice D rationale
Tamponade, a serious condition in which fluid or blood fills the pericardial sac, compressing the heart and preventing it from pumping effectively, could cause the symptoms described and would be the most concerning finding.
