NREMT Advanced EMT Practice Test #3

Answer - A - The mitral valve is located between the left ventricle and left atrium. The mitral valve is also known as the bicuspid valve. It is under the greatest amount of strain caused by pressures generated during left-ventricular contraction. In some patients, this valve progressively fails, allowing regurgitation of blood into the left atrium, increasing hydrostatic pressure in the pulmonary veins, and eventually leading to pulmonary edema.
