Final answer:
To determine if there is no compensation for a patient in acidosis or alkalosis, one should check if the pH is outside the normal range, which indicates that compensatory mechanisms are not effective.
Step-by-step explanation:
To know if there is no compensation present for a patient in either alkalosis or acidosis, one must look at the blood pH value. If compensation is occurring, the pH will be brought back towards the normal range, even if the underlying problem persists. Therefore, the correct answer to determine if there is no compensation would be B. pH outside normal range. If the pH is within the normal range, it may indicate that compensatory mechanisms have been effective. On the other hand, if the pH is outside the normal range, this would suggest that no compensation, or inadequate compensation, is taking place.
