 Welcome back to our med smarter question of the week where we're taking a smarter approach to preparing future physicians Before we get started if you'll click that like button and also subscribe and turn the bell on so that you'll be notified when we post new Videos all right. Let's get right to that question. This one is pretty much a short vignette. So We're gonna go ahead and just read the whole thing because there's only a few words that we're missing without the last sentence A patient is being treated with beta blockers for hypertension Which of the following describes the effects of beta blockers on end diastolic volume? blood pressure contractility heart rate and ejection time So this question is just asking us to know what the effects of a particular medication are Don't get overwhelmed by seeing this chart because this is a fairly straightforward question So we all know right from the start that beta blockers are gonna slow the heart rate so we can come through here and We can mark out any answer choice that causes an increase in heart rate. So B and e are going to be out because they do not fall in line with a decrease in heart rate We know beta blockers are used for hypertension. So it's gonna cause a decrease in our blood pressure But all of these answer choices as you see here have a decrease in blood pressure So that can't rule any of further doubt. So if we decrease our heart rate We're going to decrease oxygen consumption and that will also decrease our contractility Therefore we can rule out anything that has an increase in contractility or little to no effect So that is E and a so now we're down to C and D. So if we are decreasing our heart rate That gives us more time to fill up the heart and more time to empty the heart So we're going to increase our ejection time only one of these answer choices gives us an increase in ejection time and that is D Therefore D is going to be our final answer and D is the correct answer So our beta blockers will decrease contractility as we see in D and it also decreases our heart rate Therefore we have a decrease oxygen consumption that will allow for an increased in diastolic volume due to a longer Diastolic filling time increased ejection time to get all of that in diastolic volume out one further thing that you didn't have to know To answer this but that beta blockers decrease the secretion of renin Therefore our renin angiotensin cascade is going to be diminished and that is what reduces our blood pressure If you found this material helpful for your studying Please like and consider subscribing to the channel also share this video so that more people can benefit from it like you have
