C
Symptoms of diabetes insipidus include voiding large amounts of dilute urine many times a day. Nephrogenic diabetes insipidus is caused by the inhibition of the cyclic adenosine monophosphate (cAMP)–dependent action of the antidiuretic hormone on the distal-tubule collecting duct cells. This problem is sometimes associated with lithium therapy. The symptoms detailed are not consistent with any of the other options.
