The ophthalmic artery is a main branch from the internal carotid artery that provides blood supply to the optic nerve head, orbit, ocular muscle, and ocular nerves. Your patient has a long history of hypertension and has "afib" (atrial fibrillation) putting him at great risk for traveling clots - potentially traveling up to the brain through the internal carotid artery and obstruction of the ophthalmic artery.
You certainly have to keep up with who's coming and going as well as how many are coming and going. So if you initially have 267 passengers, 60% of which are males, then that means there are approximately 160 males on the flight. Of the 160 males, 15% or 24 male passengers exit or egress the plane for connection flights, meaning 136 (160 minus 24) male passengers remain on the plane. So if 37 additional males board the flight for Washington, DC then a total of 173 male passengers be aboard the plan. WOW that was a lot. Dr. Adkins can show you how to do this question in 5-10 seconds without the use of a calculator. Give Dr. Adkins a call at 301-960-4950.
So you want to be a nurse. Wow, this one seems a bit unfair, NOT REALLY - you got this. The question is, "do you know the circulatory system?" Well, if you do, then you know that blood flows into the heart on the right side into the right atrium (from the SVC, IVC, & CS - you should know these) and then passes through the tricuspid valve into the right ventricle and then into the pulmonary artery on it's way to the lungs for gas exchange. The blood then comes back to the heart on the left side via the pulmonary veins into the left atrium and pass the mitral/bicuspid valve into the left ventricle and out of the heart via the aorta. WOOOOOOW OK, now we're just warming up. So if the physical exam reveals clear lungs - NOT fluid crackles - with shortness of breath, enlarged liver, chest pain, right atrial and ventricular enlargement certainly this indicates blood is having a hard time getting past the pulmonary artery lust before the lungs and backing up on the right side. So where is the problem? If the lungs are clear and all the problems are on the right, then it's very likely that the pulmonary artery is blocked (clot) or narrowed (stenosis) or has some other pathologic process, hence answer B, the other answer just don't make logical sense.

Always following the logical clues in the question and connect the dots. If you are really ready to understand A&P and apply to knowledge to disease processes then certainly join Dr. Adkins's Science Class where we go from A - Z and beyond.
"You" are the subject of the sentence as "you" are the the subject who is doing the action of "sending" the announcements. Give them the receiver fo the invitation is the object of the sentence. Therefore, we will use "whom" to refer to the object in this case.
