  b. Partially compensated metabolic alkalosis
  c. Fully compensated respiratory alkalosis
  d. Partially compensated respiratory alkalosis

Question 2

  a. Hysteria
  b. Narcotics
  c. Atelectasis
  d. Salicylate intoxication
  e. Mechanical ventilation

Answer to Question 1

ANS: D
When the fundamental acidbase ratio is altered for any reason, the body attempts to correct the deviation. In a simple disturbance, a single primary factor affects one component of the acidbase pair and is usually accompanied by a compensatory or secondary change in the component that is not primarily affected. In respiratory alkalosis, the pH is high (?7?7.45), and the PCO2 is low (?6?35). When the pH is restored to normal, the disturbance is described as compensated. It is partially compensated because the pH remains abnormal, but the HCO3 is low (?6?22), indicating an attempt at compensation.

Answer to Question 2

ANS: A, D, E
Hysteria, salicylate intoxication, and mechanical ventilation can produce hyperventilation. Narcotics and atelectasis produce inadequate gas exchange, not hyperventilation.
