Your childhood dog, Teddy, just turned 16-years-old and you take… Your childhood dog, Teddy, just turned 16-years-old and you take her in for her yearly check-up during which Dr. Wilson, the vet, notices that she has high blood pressure. Given her age, Teddy is prescribed Vasotec, a high dose ACE inhibitor. The next day, you return home after you were out for a couple hours running errands and Teddy chewed open the bottle of Vasotec that must have fell off the ledge of the counter where you placed it when you gave Teddy her morning pill. You notice that Teddy has urinated a couple of places in the house and looks lightheaded. You count to see how many are left and you discover that she ate three additional pills.You decide to rush her to the nearest animal hospital where they take her blood pressure and find that it is very low. Which of the following best explains what might be going on in Teddy’s body after receiving multiple Vasotec pills?  Of the following options, choose the one that would help to properly match the above scenario. Reject all the rest. For full points you must also provide an explanation for each case. Defend the correct choice with adequate justification. For those that are false, explain why they are incorrect. (10pts) Accept/Reject: The extra Vasotec doses are resulting in hyposecretion of ADH from the posterior pituitary. Accept/Reject: Aldosterone release from Teddy’s adrenal medulla is reduced as result of the blood pressure medication in her system which directly results in vasoconstriction of her arterioles.  Accept/Reject: Angiotensin I is being converted into Angiotensin II more readily, leading Teddy’s low blood pressure.  Accept/Reject: The medication stimulates increased reabsorption of Na+ in the DCT causing a decrease in Teddy’s blood volume and thus a decrease in blood pressure.  Accept/Reject: The increased urination as seen with Teddy’s accidents in the house is a result of decreased expression of aquaporins in the loop of Henle.    Science Biology BIOS 343 Share (0)
