A Question Completion Status: 10 11 4 5678 9 e a. o b. QUESTION 2 2. Which of the following would be expected in a patient with nephrogenic diabetes insipidus? 1. Increased synthesis of ADH in the paraventricular nucleus 2. Decreased renin secretion 3. Decreased drinking 4. Decreased plasma osmolality d. QUESTION 3 1. A patient has the syndrome of inappropriate ADH secretion due to carcinoma of the lung. This patient also dunks greater than normal amounts of water. You would expect A Increased ADH vecretion from the pituitary gland B A large decsease in plasma osmolality C Increased renin secretion D. An inapproprianely lowe urine osmolality relative to plasma osmolalityExplanation / Answer
1---a) increased synthesis of adh in the peraventricular nucleus. As in NDI the kidney is unable to respond to ADH and ADH is excreted from the body. So body keeps making the ADH to increase water reabsorption.
B is wrong because renin increases in NDI
C is wrong because water is lost from the body so it is getting dehydrated so to rehydrate the body drinking is increased.
D is wrong because decreased plasma osmolarity will reduce the ADH secretion.
