During the admission assessment, a client admitted with chest pain reports having 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.

Auscultate breath sounds while the client is supine.

Measure the blood pressure when the client is lying and standing.

Ask the client how many pillows are used to sleep on at night.
