During a clinic interview,a client states he has been experiencing dizziness upon standing.Which nursing action is appropriate for the nurse to implement?

A) Ask the client when in the day dizziness occurs.
B) Help the client to assume a recumbent position.
C) Measure both heart rate and blood pressure with the client standing.
D) Measure vital signs with the client supine, sitting, and standing.

Dizziness upon standing is a symptom of orthostatic hypotension.The nurse should obtain orthostatic vital signs (measure pulse and blood pressure with the patient supine,sitting,and standing)to assess for orthostatic hypotension.The time of day is irrelevant to the diagnosis.If the nurse observes the patient become dizzy upon standing,the first action would be to help the client lie down,and then obtain orthostatic vital signs; but this is not necessary when the symptom is not present.The nurse needs to measure both the heart rate and the blood pressure but not only in the standing position.
