A) Space interventions and encourage rest periods.

RATIONALE

Activity intolerance in clients with anemia results from the imbalance between oxygen demand and supply. Activities should be planned to intersperse activity with periods of rest to decrease hypoxemic episodes and to decrease tissue demand for oxygen. All the other options are appropriate interventions for a client with anemia, but they do not relate to the nursing diagnosis of activity intolerance. The core issue of the question is knowledge that anemia causes fatigue and that measures to prevent fatigue need to be incorporated in the plan of care. Use this knowledge and the process of elimination to make a selection.
