Further Clarification and Authentication for the Q81

It refers to the comment of Er. Tripahti which is as follows:

"q81- doubt again-sir plz do not mind.atleast both r correct.it may be that second one is not respocible of first(but according to dr.c.g. aggrawal hod medicine-king george college)it is his view ans should be a.i also consulted many books and on net after yr explanation.but sorry sir i reached again on same .plz confirm again.dr. aggrawal is also very famous doctor of endocrine gland at india level."


Kindly refer to the following source:

Review of Medical Physiology by Ganong, pp. 230, ed. 18 edition.

Cutting out the medical terminology from the above page, it is explained that in case of a patient of diabetes insipidus, there is fallacious secretion of vasoperessin. It is a state of inadequate secretion of vasoperessin. As a result, there is increase in passing of urine. It leads to thirst and he take more fluid. The patient feels he is urinating more because he is taking too much of water.

The second cause can be that the kidney cells do not respond to the vasoperessin. As a result, again the patient passes more urine and feels thirsty.

Conclusion: In any case, the patient does not feel thirsty because there is excessive secretion of vasopressin. He feels thirty because either there is lesser secretion of vasopressin or the kidney is not responding to the hormone.
The patient feels thirsty because he has passing more urine because of the malady of lesser or fallacious secretion of vasopressin or the kidney is not responding to the hormone.

Hence ‘R’ is wrong. Only A is correct.
Therefore, the answer is c: A is true but R is false.
