KROK 1 2007 – Question 134 · KROK (Medicine) · Pathophysiology
Arterial pressure of a surgeon who performed a long operation rose up to 140/110 mm Hg. What changes of humoral regulation could have caused the rise of arterial pressure in this case?
- A. Activation of sympathoadrenal system
- B. Activation of renin angiotensive system
- C. Activation of formation and excretion of aldosterone
- D. Activation of kallikrein kinin system
- E. Inhibition of sympathoadrenal system
Hint
Prolonged emotional and physical strain acts through the fastest neurohumoral stress axis; consider which humoral change can raise the diastolic pressure within minutes rather than over hours or days.
