Thanks so much for this review! (And I love all of your videos!) Hoping to pass my RVT this Feb! :-D I think I caught a mistake, but I'm no pro: I think the answer "C" for #10 is actually for Negative Predictive Value. The answer for specificity would be true negative exams divided by the true negative exams + the false positives.
Thanks for the video. and for the tips as well! I think you've made a mistake on the answer to question. The answer to question 10 is none of the above. The answer that you have selected is for the negative predictive value and not for specificity. I've written all the formulas below: Sensitivity = True positives / (True positives + False Negatives) Specificity = True negatives / (True negatives + False Positives) Positive predictive value = True positives / All positives i.e. both true and false positives Negative predictive value = True negatives / All negatives i.e both true and false negatives
@@oanhnguyen-vf5ml Your test in one day. If still wanting to study, my advice: know ALL* the waveforms (normal vs abnormal-pathology). Memorize how it looks. Able to describe it (Ex: a lot of diastolic flow, sharp upstroke, or dicrotic notch). Understand how respiration affects abdominal press/thoracic press/diaphragm/inflow/outflow. Study subclavian steal and DVT. Know different types of aneurysm. How heart disease affect waveform. Know a little of TCD. Keep in mind, my test will be different than yours. If not planning to study, get a good night sleep and relax. If you do not pass (knock* on wood), you will be that much more prepare for the second time. I will be praying for you. I have faith in you. I will be waiting for your good news. You got it! 💪🏾🙏🏽👏🏽
Hi, I just had a few questions about some of these answers. On #4 wouldn't it be answer A or something like 'significant stenosis' because if it was occluded there wouldn't be any flow distally right? Also on #12, wouldn't it be retrograde flow since it's not going in the direction it's supposed to? I looked up the definition of 'antegrade' and it says "occurring or performed in the normal or forward direction of conduction or flow"... So since it's not going in the normal direction wouldn't the answer be Retrograde?
Number 4 is incorrect. Correct answer is A- ICA Stenosis. If there was occlusion in the proximal ICA the patient would be having a stroke and there would be no waveform.
The purpose of the circle of Willis is to reroute blood in cases of ICA occlusion. A complete ICA occlusion can lead to a stroke but with the circle of Willis can prevent that by rerouting flow via the potential collateral pathways. That being said I believe you are correct and I chose the wrong answer as this is likely a post stenotic waveform.
Thank you so much for these questions. It is very helpful. Would you please make ARDMS MSK Ultrasound Review? I find it is very difficult to find any resources. Thank you again.
that's weird. My doctor said I had cellulitis before, but the area was NOT red at all. It just felt like a giant lump was there. Went away with antibiotics
