Textbook Question
Chapter 24, Problem 3CAL
Use the following paragraph to answer questions 1–3.
Maria is 8 months pregnant. When she goes to her doctor for her checkup, the nurse takes her blood pressure. It is unusually high: 200/100 mm Hg. The nurse also collects a urine sample and detects elevated levels of protein in her urine.
3. What do you think has happened to her urine production? (Consider the pressures involved in determining net filtration pressure and osmotic force generated by solutes in the filtrate.)
- a. Urine production stays the same.
- b. Urine production increases.
- c. Urine production decreases.
- d. It is not possible to predict the effect on urine production.
