because they mention scattered fragments of foreign material (pt presents 2 months after c-section, sutures are either removed in 1 week or dissolve in few weeks (depends on type of suture material)
I think it IS a foreign body granuloma. The sutures are supposed to be removed or dissolve but sometimes one gets left in. The question says foreign material and sutures are often polarizable.
no, decreased CO => peripheral vasoconstriction => SVR will be increased
No SVR will increase due to RAAS and SAN thats why we decrease afterload in HF treatment ( ACEI, ARBs )
Wouldn't pulmonary vascular resistance also be decreased here due to pulmonary vasodilation in the setting of an MI?
@snafull: my initial thought is that we would see pulmonary vasoconstriction because of the relatively low oxygen tension (that results from the low cardiac output).
I just dont understand how that is the cause of his altered state of consciousness. Why wouldnt altered affinity of oxygen from HbA1c be correct? A1C has a higher affinity for oxygen so wouldnt that be a better reason for him being unconscious?
HbA1c is more of a chronic process. It is a snapshot of three months. Also, people can have elevated A1c without much impact on their mental status. Other organs are affected sooner and to a greater degree than the brain. DKA is an acute issue.
Can somebody please explain why 'Inability of neurons to perform glycolysis' is wrong?
Probably because they're sustained on ketones.
@snafull glucose is very high in the blood, why would neurons not be able to use it?
@snafull maybe u are confusing bc DK tissues are unable to use the high glucose as it is unable to enter cells but I dont think thats the case in the neurons?
I thought the high amount of glucose in the blood (osmotic pressure), sucks out the water from the cells. But you also pee out all that glucose and water goes with it. That's why you have to drink and pee a lot..
Neurons are not dependent on insulin, so they are not affected by utilization of glucose (only GLUT4 receptors in the muscle and adipose tissue are insulin dependent)
@titanesxvi You really enlightened me!
I don't make the connection of what titanesxvi said to the question - can someone explain?
@mutteringly it explains why the answer choice "inability of neurons to perform glycolysis" is wrong
