Answer the following:
You are treating a patient in the hospital who was admitted with signs of orthostatic hypotension
(decreased blood pressure, increased heart rate, lightheaded) secondary to having severe diarrhea and
dehydration. Which of the following would you expect to be their GFR (glomerular filtration rate) given
their symptoms? Explain your answer.
a. 85 ml/min.
b. 120 ml/min.
c. 142 ml/min
a. 85 ml/min. Dehydration decreases glomerular filtration rate.
Explain, in detail, how the cardiovascular baroceptors work to maintain blood pressure.
The cardiovascular baroceptors monitor and regulate blood volume (which is influenced directly by Na+
ion concentration) to maintain blood pressure. If blood volume (and consequently blood pressure) rises,
the baroceptors signal the kidney causing a dramatic increase in the filtration rate, increasing the output of
water and Na+ which reduces blood volume to quickly normalize the pressure.
Describe what occurs in extreme acidosis and alkalosis.
If acidosis causes the blood pH to drop below 7.0, the central nervous system is markedly
depressed causing coma and imminent death.
If alkalosis causes the blood pH to rise above 7.8, the nervous system is markedly excited causing
extreme nervousness, muscle contraction, convulsion and death usually due to cessation of breathing.
