Answer:
The “lub” is the first heart sound, commonly termed S1, and is caused by turbulence caused by the closure of mitral and tricuspid valves at the start of systole. The second sound,” dub” or S2, is caused by the closure of aortic and pulmonic valves, marking the end of systole.
The nurse will perform pulse oximetry to monitor the effectiveness of the oxygen therapy ordered for the client.
<h3>What is pulse oximetry?</h3>
The oxygen saturation level of your blood can be measured with a non-invasive procedure called pulse oximetry.
It can quickly identify even minute variations in oxygen levels. These levels demonstrate how well blood transports oxygen to your arms and legs, which are the extremities that are farthest from your heart. It looks like a little clip and is called a pulse oximeter. It fastens to a body component, usually a finger.
Pulse oximetry is helpful for postoperative patients, monitoring individuals at risk for hypoxia, titrating oxygen therapy, and monitoring patients receiving oxygen therapy.

Answer:
Deoxygenated blood enters the right atrium from the superior and inferior vena cava > The blood flows through the tricuspid valve into the right ventricle >From the right ventricle, the blood flows through the pulmonary valve into the pulmonary artery > The right and left pulmonary arteries carry deoxygenated blood to the right and left lungs for gas exchange > The blood releases carbon dioxide as waste and picks up a fresh supply of oxygen > The oxygenated blood flows through the pulmonary veins from the lungs into the left atrium > From the left atrium, the blood flows through the bicuspid, or mitral valve into the left ventricle > Left ventricular contraction forces blood through the aortic valve into the aorta for distribution to the systemic circulation
