©FYNDLAY 2024/2025 ALL RIGHTS RESERVED 1:52PM. 1 TAMU NURS 617 EXAM 2 Questions And Answers 2025 Update. During the cardiac cycle, which structure directly delivers action potential to the ventricular myocardium? a. Sinoatrial (SA) node b. Atrioventricular (AV) node c. Purkinje fibers d. Bundle branches - Answerc. Purkinje fibers Each cardiac action potential travels from the SA node to the AV node to the bundle of His (AV bundle), through the bundle branches, and finally to the Purkinje fibers and the ventricular myocardium, where the impulse is stopped. The cardiac electrical impulse normally begins spontaneously in the sinoatrial (SA) node because it: a. Has a superior location in the right atrium. b. Is the only area of the heart capable of spontaneous depolarization. c. Has rich sympathetic innervation via the vagus nerve. d. Depolarizes more rapidly than other automatic cells of the heart - Answerd. Depolarizes more rapidly than other automatic cells of the heart The electrical impulse normally begins in the SA node because its cells depolarize more rapidly than other automatic cells. ©FYNDLAY 2024/2025 ALL RIGHTS RESERVED 1:52PM. 2 What can shorten the conduction time of action potential through the atrioventricular (AV) node? a. Parasympathetic nervous system b. Catecholamines c. Vagal stimulation d. Sinoatrial node (SA) - Answerb. Catecholamines Catecholamines speed the heart rate, shorten the conduction time through the AV node, and increase the rhythmicity of the AV pacemaker fibers. If the sinoatrial (SA) node fails, then at what rate (depolarizations per minute) can the atrioventricular (AV) node depolarize? a. 60 to 70 b. 40 to 60 c. 30 to 40 d. 10 to 20 - Answerb. 40 to 60 If the SA node is damaged, then the AV node will become the heart's pacemaker at a rate of approximately 40 to 60 spontaneous depolarizations per minute. Within a physiologic range, what does an increase in left ventricular end-diastolic volume (preload) result in? a. Increase in force of contraction b. Decrease in refractory time c. Increase in afterload d. Decrease in repolarization - Answera. Increase in force of contraction This concept is expressed in the Frank-Starling law; the cardiac muscle, like other muscles, increases its strength of contraction when it is stretched. ©FYNDLAY 2024/2025 ALL RIGHTS RESERVED 1:52PM. 3 As stated in the Frank-Starling law, a direct relationship exists between the _____ of the blood in the heart at the end of diastole and the _____ of contraction during the next systole. a. Pressure; force b. Volume; strength c. Viscosity; force d. Viscosity; strength - Answerb. Volume; strength As stated in the Frank-Starling law, the volume of blood in the heart at the end of diastole (the length of its muscle fibers) is directly related to the force (strength) of contraction during the next systole. What physical sign is the result of turbulent blood flow through a vessel? a. Increased blood pressure during periods of stress b. Bounding pulse felt on palpation c. Cyanosis observed on excretion d. Murmur heard on auscultation - Answerd. Murmur heard on auscultation Where flow is obstructed, the vessel turns or blood flows over rough surfaces. The flow becomes turbulent with whorls or eddy currents that produce noise, causing a murmur to be heard on auscultation, such as occurs during blood pressure measurement with a sphygomanometer. What is the initiating event that leads to the development of atherosclerosis? a. Release of the inflammatory cytokines b. Macrophages adhere to vessel walls. c. Injury to the endothelial cells that line the artery walls d. Release of the platelet-deprived growth factor - Answerc. Injury to the endothelial cells that line the artery walls Atherosclerosis begins with an injury to the endothelial cells that line the arterial walls. Possible causes of endothelial injury include the common risk factors for atherosclerosis, such as ©FYNDLAY 2024/2025 ALL RIGHTS RESERVED 1:52PM. 4 smoking, hypertension, diabetes, increased levels of low-density lipoprotein (LDL), decreased levels of high-density lipopro
