During the admission assessment, a male client admitted with chest pain states he has no breathing problems and no trouble sleeping at night. To obtain further data regarding possible orthopnea, which action should the nurse take?

Observe for jugular vein distention while the client is flat in bed.

Measure the client's blood pressure when he is lying and standing.

Ask the client how many pillows he sleeps on at night.

Auscultate the client's breath sounds while he is supine.
