Which of the following is TRUE about the blood pressure determinants?
- A. Hypervolemia lowers BP
- B. Hypervolemia increases GFR
- C. HCT of 70% might decrease or increase BP
- D. Epinephrine decreases BP
Correct Answer: C
Rationale: Hematocrit (HCT) 70% e.g., polycythemia can raise BP (viscosity) or lower it (poor flow), unlike hypervolemia (raises BP, GFR), or epinephrine (raises BP). Nurses assess this e.g., in anemia for variable impacts, per circulatory dynamics.
