Question How should the blood pressure cuff be positioned on the patient? The hoses on the cuff should be facing anterior and exiting the cuff away from the hand. The hoses on the cuff should be facing posterior and exiting the cuff toward the hand. The hoses on the cuff should be facing posterior and exiting the cuff away from the hand.

Question Identify the description with the correct vessel type - artery (A), capillary (C), or vein (V).   Carry blood away from the heart     Have the thickest walls     Converge to form veins     Have the lowest pressure     Carries the pulse     Most numerous blood vessels     Contains the most elastin to stretch and recoil     Carry blood to the heart     Branch to form capillaries     Have the highest pressure     Site of diffusion     Have valves     Most narrow diameter     Provide large surface area for exchange of materials (gases, nutrients, wastes)

Explain correct answer

In a normal beat the heart ejects about 90% of the blood in its chambers.  True  False

What part of the heart act as a shock absorber

True or false. The aorta branches into the left coronary artery/LCA, which supplies blood to both ventricles and the anterior 2/3 of the interventricular septum.

The standard EKG consists of 10 sensors that record 12 leads of the heart’s electrical activity from different angles, allowing for a thorough three-dimensional interpretation of its activity. This is transmitted by the electrodes to the equipment to be interpreted and is used to diagnose cardiac medical conditions. In case of an abnormal EKG, the second step would be to use a Holter monitor. How would you explain to your classmates how to perform an EKG (steps)? Where will you place the electrodes when performing and EKG? Why? What are the different lead types, connections, and placements? When you conclude an EKG, what are the different components that you need to observe and confirm before you disconnect the patient? Can you explain the difference between normal, abnormal, and artifacts? What is a Holter monitor? Under what circumstances would one be ordered for a patient? How do you use a Holter monitor? Educate a patient: What you will do before, during, and after an…
