Question about calcium channel blockers and ICP/CPP
I understand that CPP and ICP are very complicated, so please forgive my dummbassery. Since calcium channel blockers increase cerebral blood flow (by arterial dilation) but also decrease blood pressure, would they then increase cerebral perfusion pressure without the need for higher blood pressure? Similarly, would it increase ICP since increased cerebral blood flow would lead to more volume in the intracranial space? (Source: Student Doctor Network)

CHF treatment options
Why are calcium channel blockers (CCB) contra-indicated in congestive heart failure, while beta-blockers aren't?
I understand that CCB may worsen the situation with a significant drop in cardiac output (CO), since they're negative inotropes and can further deteriorate the cardiac function.... but don't beta-blockers ultimately do the same thing? They're negative chronotropes, so they will also cause a decrease in CO. Why can they be used in heart failure while CCB cannot?
Thanks in advance. (Source: Student Doctor Network)

Attending psychiatrist suspects delirium.
Medical service treats medical problems over the course of 1 week, but mania/psychosis/confusion persist. Brain imaging and extensive lab workup unremarkable for ongoing...

Vitamin D supplementation
Riddle me this:
If someone is osteopenic, we give Calcium/Vitamin D supplementation. The vitamin D in caltrate is 400 U of D3, BID, so that's 5600 U of D3 per week. (that D3 is a calcitriol analog, right? read to go).
If we later find out same patient is 25-hydroxy deficient (the typical lab we check), does it then make sense to add ergocalciferol (a D2 analog), 50KU/week, on top of the D3 we're giving? Put another way, if you're already giving a D3 analog, why would you give a D2...

RN to MD/DO or PA?
Hi,
I am currently an RN (been working almost 2 years now) thinking about eventually going back to school for either PA or MD/DO. I know the next step for an RN would generally be NP, but I honestly don't think that is the right track for me. The nursing model is great - I like the holistic approach to patient care, but I want to know more and why we do what we do. Why are we giving beta blockers for patients heart failure? Why amiodarone or calcium channel blockers for AFib? What...

Codes in known hyperkalemia - best initial approach?
So you have a patient with known hyperkalemia in the admission, lets say it was running in the high 6s with some EKG changes and you have a good reason to think that's why he arrested.
You start ACLS and he has no central access or anything. What's the ideal timing and sequence of pushing meds? Immediately giving calcium gluconate (3g) with insulin/dextrose (5 and 25) followed by 100 bicarb? And re-dose calcium subsequently if no success while addressing other possible causes as acls continues? (Source: Student Doctor Network)
