Question

Dan has been lost in the desert for 2 days with very little water. As a result of this exposure, you would expect to observe which of the following?
a. elevated ADH levels
b. decreased blood osmolarity
c. normal urine production
d. increased blood volume
e. increased interstitial fluid

Answer 1

Answer:

The correct answer is a. elevated ADH levels

Explanation:

The function of ADH is to regulate the excretion of water from kidneys. As Dan has been lost in the desert for 2 days his body must be dehydrated and in stress which gives signal to hypothalamus gland to increase ADH level.

Once ADH level is increased his kidney starts reabsorbing as much water as it can preventing his body to become dehydrated and  reduce his urine amount.

So the correct answer is a. elevated ADH levels
