Question

You interview a patient and her main complaint is the generation of vast quantities of dilute urine and the need to drink large amounts of water. Her blood glucose is normal. You tell her that she has the disease ________ as a result of insufficient release of/or response to the hormone __________. a) Diabetes insipidus, aldosterone b) Type I Diabetes, antidiuretic hormone (ADH) c) Type II diabetes, antidiuretic hormone (ADH) d) Diabetes insipidus, antidiuretic hormone (ADH) e) Diabetes insipidus, oxytocin

Explanation / Answer

30) The patient is secreting large amounts of dilute urine. Her blood glucose levels are normal. Therefore, she is suffering from diabetes insipidus. This condition is characterised by the insufficient release or response to anti diuretic hormone (ADH). Receptors for ADH are present in the collecting duct if the nephron from where tubular reabsorption of water takes place. In the absence of ADH, water reabsorption does not occur resulting in excretion of large amounts of dilute urine. So, the answer for this question is option d (diabetes insipidus, anti diuretic hormone ADH).
