Test Bank - Applied Pathophysiology for the Advanced Practice Nurse 1ST Edition Lucie By Dlugasch, Lachel Story | Complete 2023/2024. A 50-year-old man is having an acute myocardial infarction and will be administered recombinant tissue plasminogen activator (t-PA). The medication activates plasminogen in order to: A) decrease platelet adhesion. B) increase clotting time. C) promote fibrinolysis. D) promote coronary vasodilation. Ans: C Complexity: Easy Ahead: Hematopoietic System Subj...

What is the Physiologic purpose of the PDA? - Answer Purpose in the fetus is to divert blood away from lungs in utero -Lungs are not needed in utero to oxygenate the blood, oxygenation is provided by the placenta How does the PDA work? - Answer -After birth and clamping of the umbilical cord and the first breath, the pulmonary vasculature relaxes, allowing blood to flow in, and systemic blood pressure rises, preventing continued flow of blood from the aorta crossing the PDA into pulmonar...

what are 3 'systems' of blood circulation that we discussed in class? (Ans- pulmonary system systemic system coronary system during ventricular systole, what is happening to the blood volume within the ventricle? (Ans- first, there is no change-once pressure is great enough and the semilunar valves one, volume drops what 3 veins empty into the right atrium (Ans- superior vena cava, inferior vena cava, coronary sinus an individual has an increase in afterload, what effect wo...

_____ what facilitates the contraction of the atrial appendages? a. drop in pressure in the atria during systole b. squeezing of the pericardium with cardiac contraction c. pectinate muscle in the walls of the appendages d. increased thoracic pressure with deep inspiration - c. pectinate muscle in the walls of the appendages __________ small fibrous nodular areas that are normally identified on the central part of the aortic cusps. a. chronic thrombus accumulation causes b. nodules of a...

The nurse is preparing to teach a prenatal class about fetal circulation. Which statements would be included in the teaching plan? Select all that apply. A. "The ductus arteriosus allows blood to bypass the fetal lungs." B. "One vein carries oxygenated blood from the placenta to the fetus." C. "The normal fetal heartbeat range is 160 to 180 beats per minute in pregnancy." D. "Two arteries carry deoxygenated blood and waste products away from the fetus to the placenta." E. "Two vein...

allows blood to flow directly from the right atrium into the left atrium to bypass pulmonary circulation - foramen ovale carries blood from the umbilical vein to inferior vena cava; allows some blood to bypass the liver - ductus venosus atrial contraction; systole; p wave - atrial depolarization max volume of air that can be exhaled following maximal inhalation - vital capacity allows blood in pulmonary artery to flow directly into the descending aorta to bypass the pulmonary circulation ...
