Benjamin,
In practice at sea there generally isn't a problem knowing which pole to work off of with the Z value. If there are doubts then use a hand bearing compass, PV formula, or Weem's Line of Position graph (attached).
Prime Vertical (PV) = Arc Sin { Sin Declination / Sin Latitude
The prime vertical is the altitude of a body when bearing 90°° or 270°.
