Question 1 of 5
A nurse is teaching the patient with mitral valve problems about the valves of the heart. Starting on the right side of the heart, describe the sequence of blood flow through these valves. 1. Mitral; 2. Aortic; 3. Tricuspid; 4. Pulmonic
Correct Answer: C
Rationale: The correct sequence of blood flow through the valves of the heart, starting on the right side, is tricuspid (3), pulmonic (4), mitral (1), aortic (2). This is because blood first enters the right atrium through the tricuspid valve, then passes to the right ventricle through the pulmonic valve. From there, it is pumped to the lungs for oxygenation. Oxygenated blood returns to the left atrium through the pulmonary veins, passes through the mitral valve to the left ventricle, and is then pumped out to the body through the aortic valve.
Choice A (4,3,2,1) is incorrect as it reverses the order of the valves.
Choice B (1,3,2,4) is incorrect as it starts with the mitral valve before the tricuspid valve.
Choice D (2,4,1,3) is incorrect as it starts with the aortic valve before
