Welcome back everyone. Our next question says Mr Johnson, a 60 year old man recently had a heart attack and was prescribed blood thinning medication. How will this medication affect the blood clotting process? A it will directly enhance flood clotting B? It will trigger severe bleeding C, it will produce more hormones that are responsible for blood clotting and D it will inhibit blood clot formation and reduce the risk of blockage in blood vessels. So in a heart attack, there's often a blockage of the coronary artery, often by a blood clot, which we can assume is the case here since he was prescribed a blood thinning medication, when the coronary artery is blocked, it blocks blood flow to the heart, which can then cause damage to the heart muscle. So you would use blood thinning medication to prevent the formation of blood clots which might cause further blockage as has happened already. So choice D would be the answer here. It will inhibit blood clot formation and reduce the risk of blockage in blood vessels. You would not want choice. A it will directly enhance blood clotting. That would be exactly the opposite of what you want to do. And you can even just look at the name blood thinning medication prevents clotting. In addition, you can also rule out choice C it will produce more hormones that are responsible for blood clotting. We don't want more blood clotting. You wouldn't want hormones that cause it. And then finally, choice B, it will trigger severe bleeding. Um Blood thinning, make blood thinning medication can make a person at more higher risk of having excessive bleeding, but it would not trigger severe bleeding or you wouldn't give it as a medication. Obviously. So choice B, not our answer is that's not the desired effect of the blood thinning medication. So the medication that's prescribed after a heart attack, how will it affect the blood clotting process? Choice D it will inhibit blood clot formation and reduce the risk of blockage in blood vessels. See you in the next video.
