The nurse would not expect full compensation to occur for which acid-base imbalance?
a. Respiratory acidosis
b. Respiratory alkalosis
c. Metabolic acidosis
d. Metabolic alkalosis
ANS: B
Usually the cause of respiratory alkalosis is a temporary event (e.g., an asthma or anxiety attack). The kidneys take about 24 hours to compensate for an event, so it is unlikely to see much if any compensation for respiratory alkalosis. Respiratory acidosis usually results from longer-term con-ditions such as chronic lung disease, narcotic overdose, or another event that causes respiratory depression. The kidneys still do not respond for about 24 hours, but usually the event is still oc-curring. For both metabolic imbalances, the respiratory system is quick to attempt to compensate: however, it may have difficulty sustaining that compensation.
