Final answer:
Dry oral mucous membranes and orthostatic blood pressure changes are nursing assessment data that identify an older adult client's risk for falling.
Step-by-step explanation:
The nursing assessment data that identify an older adult client's risk for falling are:
- Dry oral mucous membranes: Dehydration can lead to dryness of the oral mucosa, making it more difficult to speak or swallow.
- Orthostatic blood pressure changes: Orthostatic hypotension, a sudden drop in blood pressure when standing up, can increase the risk of falling.
The other options are not directly related to the risk of falling. A pulse rate of 72 beats/min and bounding is within the normal range, and a serum potassium level of 4.0 mEq/L is also within the normal range.
