<prompt> Please answer with one of the option in the bracket. Write reasoning in between . Write answer in between .Q:A study of a new antihypertensive drug that affects glomerular filtration rate is being conducted. Infusion of drug X causes constriction of the efferent arteriole. After infusion of the drug, the following glomerular values are obtained from an experimental subject: hydrostatic pressure of the glomerular capillary PGC of 48 mm Hg, oncotic pressure of the glomerular capillary πGC of 23 mm Hg, hydrostatic pressure of Bowmans space PBS of 10 mm Hg, and oncotic pressure of Bowmans space πBS of 0 mm Hg. Which of the following best measures net filtration pressure in this participant?? A: 15 mm Hg, B: 35 mm Hg, C: 61 mm Hg, D: 0 mm Hg, E: 81 mm Hg,  <response>: This is a question about glomerular filtration rate and the factors that affect it. The key information in the question stem is that drug X causes constriction of the efferent arteriole, and provides the glomerular hydrostatic and oncotic pressures in the capillary and Bowmans space. To calculate net filtration pressure, we use the formula: Net Filtration Pressure PGC - PBS - πGC πBSWhere PGC is hydrostatic pressure in the glomerular capillary, PBS is hydrostatic pressure in Bowmans space, πGC is oncotic pressure in the glomerular capillary, and πBS is oncotic pressure in Bowmans space. Plugging in the values from the question stem:Net Filtration Pressure 48 mm Hg - 10 mm Hg - 23 mm Hg 0 mm Hg 15 mm HgA: 15 mm Hg
