Consumption of alcohol leads to an increase in dilute urine production by reducing the level of the hormone ADH.
Which of the following are correct statements about alcohol and/or ADH?
1 ADH travels in the bloodstream.
2 There is a positive correlation between the level of ADH and the production of dilute urine.
3 Increased ADH leads to increased formation of dilute urine.
4 A reduced level of ADH could lead to dehydration.

Answer:

17) C

1 – Since ADH is a hormone, it has to travel in the bloodstream. So this is correct. 

2 – ADH causes water to be reabsorbed into the bloodstream from the kidney. Hence, urine produced would be concentrated and not dilute. 

3 – Same concept. Increased ADH will cause increase in concentrated urine and not dilute urine. 

4 – This is correct. ADH is released by the pituitary gland to reabsorb water from the kidney to prevent dehydration. If ADH is reduced, dehydration can occur. 

The answer is C.
