About this Exam
Prepare with the Cardiovascular Disorders and Treatment Practice Test practice quiz. This question bank includes 10 questions covering term, heart, breathing, cardiovascular, and disorders. Use it to review important concepts, identify knowledge gaps, and build confidence for the related exam, course, or assessment.
Sample Questions
Question
1
What are symptoms of endocarditis?
Explanation:
Endocarditis is an infection that involves the inner lining of the heart and often the valves. The most telling signs come from how the valves are affected: a new or changed heart murmur reflects valve involvement, and if the valve dysfunction progresses, it can lead to fluid retention and symptoms of heart failure. Fever and general malaise are also common, but the key cardiac clues are the valve problems with a murmur and signs of fluid overload. The option describing heart valve problems, a new or changed heart murmur, and fluid retention best fits the typical presentation of endocarditis. Shortness of breath alone, chest pain on exertion alone, or an irregular heartbeat by themselves don’t capture the valve-related and heart-failure aspects that endocarditis commonly causes.
Question
2
Which term describes shocking the heart to restart it or reset an abnormal rhythm?
Explanation:
Defibrillation is the electric shock delivered to the heart to reset its rhythm and restart a heartbeat when a life‑threatening arrhythmia occurs. By depolarizing a large portion of the heart muscle at once, it briefly halts chaotic electrical activity, allowing the heart’s natural pacemaker to reestablish a normal rhythm. This is done with an AED or defibrillator in emergencies when there is ventricular fibrillation or pulseless ventricular tachycardia. The other descriptions refer to the rhythm itself, a clot, or breathing trouble, none of which describe the act of delivering an electrical shock to restore normal heart rhythm.
Question
3
BNP levels rise in response to what condition?
Explanation:
BNP is released by ventricular myocytes in response to increased stretch of the ventricular walls, which happens with elevated filling pressures and volume overload. This stretch stimulates BNP release, and the peptide then acts to reduce preload and afterload by promoting natriuresis, diuresis, and vasodilation. That’s why BNP levels rise with increased ventricular filling pressures. Decreased heart rate doesn’t directly trigger BNP release; liver congestion and renal failure can be associated with high BNP for different reasons (consequence or clearance), but the primary stimulus for BNP rise is the ventricular stretch from elevated filling pressures.
Question
4
What is the role of nitroglycerin in treating heart failure?
Explanation:
Nitroglycerin works primarily as a vasodilator that lowers the heart’s workload by reducing preload. By dilating veins, it decreases venous return to the left ventricle, which lowers left ventricular filling pressures and wall stress. This reduction in myocardial oxygen demand helps relieve chest pain due to ischemia and can improve blood flow to the heart muscle. In heart failure with congestion, the preload reduction also eases pulmonary edema and dyspnea, making it easier for the heart to circulate blood. It does not suppress the immune system, it isn’t used to deliberately raise heart rate, and it doesn’t promote diuresis (that’s the role of diuretics).
Question
5
BNP is a marker secreted when there is too much pressure in which organ?
Explanation:
BNP is produced mainly by the ventricular myocardium in response to increased wall stress from volume or pressure overload. When the heart, especially the left ventricle, is under strain due to heart failure or elevated filling pressures, it releases BNP into the bloodstream. This makes BNP a useful biomarker for cardiac dysfunction, reflecting how hard the heart has to work to pump blood. The other organs listed don’t generate BNP in response to heart-wall stretch—the hormone is tied to cardiac pressure/volume overload, whereas the liver, lungs, and kidneys have different regulatory roles and do not release BNP as a signal of ventricular pressure.
