In many ways, Carlos' case appears to be a typical case of gastroenteritis, but a few initial findings are troubling. Prolonged diarrhea, fever, and bloody stools are not common findings in gastroenteritis. Carlos' mother also mentioned that he was not urinating much in the past two days, which raises another red flag. Carlos' blood pressure is elevated, particularly for a 5-year-old patient. High blood pressure is not what the medical team would expect if Carlos was dehydrated. At this point, the medical team knows that it needs more information about Carlos' condition. In addition, they are concerned that Carlos' renal function may be compromised, based on his presentation with diarrhea and reduced production of urine. They decide to admit Carlos to the hospital for close observation of his condition and to gather more information by ordering several different clinical lab tests.

We have clinical information that indicates Carlos is dehydrated, which means that the amount of water in his blood plasma has decreased. Recall the three basic processes that the kidney uses to perform its homeostatic functions. Which of the following correctly describes how Carlos' kidneys are trying to compensate for his low blood volume?

Recall the three basic processes that the kidney uses to perform its homeostatic functions. Which of the following correctly describes how Carlos' kidneys are trying to compensate for his low blood volume?

a. The amount of water secreted into the tubular fluid is increased.

b. The amount of blood plasma filtered through the glomeruli will increase.

c. The amount of water recovered by tubular reabsorption will increase.

d. The amount of water recovered by tubular reabsorption will decrease.
