Compare the terms concentric and eccentric. Why do you think eccentric plaque causes turbulence?
What will be an ideal response?
Concentric refers to circles within circles, or in the case of plaque, circular layers that build upon each other, eventually narrowing the diameter of the vessel lumen. Eccentric describes a less predictable pattern of accumulation. Blood flowing through concentric plaque still moves more or less in a straight line. Blood moving through an artery with eccentric plaque does not move in a straight line. Pockets formed by irregularly shaped outcroppings of plaque cause the blood to change directions, resulting in swirls and turbulence.

While attempting to resuscitate a middle-aged woman in cardiac arrest, you perform effective CPR but do not evaluate the patient's cardiac rhythm until 10 minutes into the resuscitation attempt. When the cardiac monitor is finally applied, the patient is in asystole. The patient is transported but is pronounced dead upon arrival at the hospital. Which of the following statements regarding this scenario is correct?
A) The delay in evaluating the patient's cardiac rhythm constitutes a breach of duty and could be proven to be the proximate cause of her death. B) Simple negligence can be established because of the delay in applying the cardiac monitor, but your inaction did not proximately cause her death. C) Your inaction reflects gross negligence and it easily could be established that the patient would have survived if the cardiac monitor had been applied earlier. D) Although there was a delay in applying the cardiac monitor, you cannot be held liable, because effective CPR was performed throughout the resuscitation attempt.
