IV RUS could you pause the IV and then close the rollerclamp to prevent backflow?
I get that pausing IV and then clamping ext set prevents backflow but wouldnt pausing and then closing...
Hi all, Just a few questions: 1. Why do we need two sets of clamps at bedside for a chest tube? 2. If we use them to assess for a leak where are they placed? If we use them to change the system...
Ok... love your detail. So, if I'm assessing for a leak 1. Clamp with 1 clamp closest to the patient, if there is still a leak then use the 2nd clamp to clamp a small ways down from the patient? If...
Hi all, I have a few questions about chest tubes and CVAD dressing changes: 1. Why do we need to sets of clamps bedaide for a chest tube? 2. If the clamps are for leak assessment, how are they...
So, I'm studying for my boards and have a few questions: 1. What is the purpose of having two hemostats or clamps at the bedside? I've read a few conflicting things. 2. How do you actually assess for...
Hi, I have been reading up on ascites and have a few questions. With liver damage and portal hypertension I've read that the ascitic fluid is "protein rich" yet a patient with a nutrition and protein...
Ok, but how does the protein leave vascular volume? It states protein remains within vascular spaces to keep osmotic pressure and endothelial cells do not permit their passage except in cases of burns...
If protein is what "keeps" fluid in vascular spaces and a lack of protein causes ascites as in malnutrition, then how is ascitic fluid caused by portal hypertension "protein
So, if a prolapsed cord causes variable decels this indicates that at some point compression is letting up? Ok, if this is true how does an engaged fetus with a mashed cord relent? That makes no...
See, that's what I would think also. Like a complete blockage of flow... in which case increasing moms BP and O2 isn't going to matter. Maybe once a nurse pushes on the presenting part to relieve...
So, if it mirrors a CTX in respect to timing but appearance is rapid onset and recovery ud still call it a variable rather than an early? Also ATI suggests 8-10 L of O2 to mom for a prolapsed cord......
Also, if a CTX is causing the compression, then why would it be a variable decel which I thought had nothing to do with a contraction??? Like variable decels aren't related to ctx and can happen...
See, that's my thought but my teacher said "cord compression" causes variable decels and threw prolapse on the list. Welp, I've researched and variable decels actually resolve and the FHR returns to...
Hi, I am very confused on the concept of saline locks. Yes, I know it's for vascular access, but how does it actually keep blood from traveling back up the catheter? Does the catheter remain full of...
So say a patient has a periphereal IV removed and saline locked wouldn't it have a positive pressure cap at the end? So basically the positive pressure cap acts as your finger would over a straw? And...
Btw the straw example is grrreeeaaattt love it. I have to ahave clear understanding of concepts and that straw reference is going in my back pocket. I'm gonna share that with my
ok so the catheter inside the vein remains full of NS or hep whichever is ordered? Like it remains in the catheter without dripping out into the vein? That's what's got me a
