Question

7. Pedialyte is a beverage which contains the same concentration of ions (K , Cl-, and Na ) as found in the plasma. Gatorade and Powerade mimic (although are not identical to) Pedialyte. Therefore, we might expect that consumption of Pedialyte should not significantly alter the osmolarity of the blood. How would you expect the urine production rate in the Pedialyte group to compare to that of the water group

Answer 1

Answer:

Less urine production.

Explanation:

The urine production rate in the Pedialyte group is lower as compare to that of the water group because the presence of K, Cl-, and Na ions. The precise combination of electrolytes and sugars in Pedialyte helps in restoring fluid levels and the nutrients in the body that are lost through sweating, urinating, or vomiting and diarrhea. We know that the presence of sodium ions regulation water and electrolyte balance in the body so there is less urine produced by taking Pedialyte group.

Answer 2

The  urine production rate in the Pedialyte group to compare to that of the water group -

Pedialyte group - decreased

water group - increased.

The rate of urine output is the urine production in a unit of time. The normal range of urine output is 800 to 2,000 milliliters per day if you have a normal fluid intake of about 2 liters per day.

• Drinking Pedialyte increases the ion concentration in the plasma that causes hyperosmolarity.
• This is sensed by the hypothalamus and releases ADH that leads to more fluid absorption in later DCT and collecting tubules that leads to decrease urine output.
• On the other hand, if you drink water, hypoosmolarity in blood plasma which does not sense by the hypothalamus and does not release ADH, and the urine output is more than the previous case.

Thus,  

The urine production rate in the Pedialyte group to compare to that of the water group -

Pedialyte group - decreased

water group - increased.
