Chapter 21, Problem A2CRE

Does the first heart sound (lubb) occur before or after the QRS complex and explain why this is the case? (I need descriptions of considering the both possibilities). Your answer should include a description about what the QRS complex represents, whether the relevant heart chamber is contracting or relaxing, the specific valves involved, and how the pressure within the relevant heart chamber determines whether these valves are open or closed. Does the second heart sound (dupp) occur before or after the T wave and explain why this is the case? (I need descriptions of considering both of the possibilities). Your answer should include a description about what the T wave represents, whether the relevant heart chamber is contracting or relaxing, the specific valves involved, and how the pressure within the relevant chamber and vessels determines whether these valves are open or closed. Before the real exam begins, I would really appreciate seeing how these questions could be answered in…

what makes the first (lubb) and second (dupp) heart sounds? what does the time interva between the start of the P wave and start of the QRS complex represent in terms of the AV node? Describe the flow of oxygenated blood from the first heart sound (lubb) to the finger. Your answer should include the name of the relevant heart chamber, the direction of blood flow through the relevant valve, the name of the elastic artery that the oxygenated blood is ejected into, and the type of blood vessel that ransports the oxygenated blood to the fingers. Why is there a delay between the first heart sound (lubb) and onset of the rising phase of the pulse pressure? State the normal resting mean arterial pressure (include units of measure) and name one lifestyle factor that could account for variation in resting mean arterial pressure between individuals? Before the real exam begins, I would really appreciate seeing how these questions could be answered in a detailed and well-structured way. I'm…

Is there are any gaps in how healthcare aides (HCAs) are integrated into team discussions or care planning? From my experience, it seems HCAs are sometimes left out of broader care conversations, even though they have valuable insight from their close interactions with patients. What strategies do you think could help ensure their perspectives are more consistently included?
