Question 1 0.125 out of 0.125 points Mitral stenosis is associated with Selected Answer: c. a pressure gradient across the mitral valve. Correct Answer: c. a pressure gradient across the mitral valve. Response Feedback: Mitral stenosis is characterized by an abnormal left atrial– left ventricular pressure gradient during ventricular diastole. Mitral stenosis is not associated with an S 4 heart sound. Mitral stenosis is associated with left atrial hypertrophy, not left ventricular hypertrophy. Mitral stenosis does not have a symptom of a muffled second heart sound. Question 2 0.125 out of 0.125 points A patient with pure left-sided heart failure is likely to exhibit Selected Answer: a. pulmonary congestion with dyspnea. Correct Answer: a. pulmonary congestion with dyspnea. Response Feedback: Left-sided heart failure is most often associated with left ventricular infarction and systemic hypertension. The ineffective pumping of the left ventricle results in an accumulation of blood within the pulmonary circulation. As a result, pulmonary congestion with dyspnea is an expected finding. Jugular vein distention is more often associated with right-sided failure. Peripheral edema is associated with right-sided failure. Hepatomegaly is not seen in pure left-sided edema. Question 3 0.125 out of 0.125 points Critically ill patients may have parenterally administered vasoactive drugs that are adjusted according to their _____ pressure. Selected Answer: c. mean arterial

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
