A nurse in a provider's office is caring for a client who reports dizziness and light-headedness upon standing and waking up at night to void. What actions should the nurse take? Select all that apply.

The correct actions are A, D, and E. A is correct because dizziness and light-headedness can be symptoms of dysrhythmias, so monitoring for any abnormal heart rhythms is crucial. D is correct because the client's symptoms suggest orthostatic hypotension, so checking for this condition is important. E is correct because advising the client to change positions slowly can help prevent dizziness and falls associated with orthostatic hypotension. B is incorrect as restricting potassium intake is not indicated for these symptoms. C is incorrect as there is no mention of medication in the scenario.
