下图显示3个心室功能曲线（The following figure shows three ventricular function curves） self-collected Feel very useful So upload to baidu Share it with you! TBL (cyclic physiology) applied practice (2011-4-6) Sun yat-sen university, zhongshan university medical school Professor wang ting huai Name class fraction 1. Which of the following most likely causes Rodriguez to generate water and sodium retention? C A, the high sodium diet B, the filtration fraction increased C, renal sympathetic activity elevated D, and prostaglandin synthesis inhibitor (bulofen) E, smoking, A choice high sodium diet can rapidly improve the osmotic pressure of plasma To transfer the water of intracellular and interorganizational fluid The blood volume increases rapidly Kidney supply improved However, the glomerular filtration rate also increased Increased drainage and lower sodium levels; It is not likely that the B option has been added to the patients with congestive heart failure; The increase of renal sympathetic activity may lead to water retention The heart failure causes the output of the heart and the effective circulation decreases On the one hand the RAAS system is activated Safe water and sodium potassium discharge; On the other hand, there is excitement Renal vasoconstriction Renal blood flow declined The filter scores went down Water sodium retention; D option using prostaglandin synthesis inhibitors nearly Finn is mainly by inhibiting prostaglandin synthesis and play a role, because the white blood cell activity and lysosomal enzyme release is inhibited, the reduce of local tissue pain impulses, reduced susceptibility pain receptors, ultimately achieve analgesia, anti-inflammatory effect; E option smoking can bring energy to the patient Most likely to be achieved by stimulating the sympathetic nerves So the most likely option is C 2. Many patients with congestive heart failure showed elevated levels of blood ADH The reason is? D A, plasma osmotic pressure increases B, water, sodium retent
