Patho Quiz 2 - Practice quiz PATHOPHYSIOLOGY

1)    Which acid-base imbalance results from impaired expiration due to emphysema? Respiratory Acidosis

2)  Inpatients with impaired expiration associated with emphysema, effective compensation for the acid-base imbalance would be: decreased urine pH and increased serum bicarbonate

3)  An anxiety attack often causes hyperventilation leading to: decreased PCO₂

4)  A prolonged state of metabolic acidosis often leads to: hyperkalemia

5)  Which of the following is a manifestation of respiratory alkalosis? Increased nervous system irritability

6)  Which two ions are most important for acid-base balance in the body? Cl and HCO₃

7)  The bicarbonate-carbonic acid buffer system helps maintain serum pH. The balance of the carbonic acid and bicarbonate ion levels are controlled by the: lungs and kidneys

8)  Alkalosis increases irritability and spontaneous stimulation of nerves by: increasing the permeability of nerve membranes

9)  What are the three mechanisms that control or compensate for serum pH? Buffer pairs in blood, change in kidney excretion rate, change in respiration rate

10)  A specific defense for the body is: sensitized T lymphocytes

11)  The inflammatory response is a nonspecific response to: any tissue injury

12)  Chemical mediators released during the inflammatory response include: histamine and prostaglandins

13)  Granulation tissue is best described as: highly vascular, very fragile, and very susceptible to infection
