Baseline vital signs, especially blood pressure and pulse. May cause changes in BP and atrial fibrillation Orientation Affect Reflexes

Important nursing care alongside medication administration with Timolol?
Clean patients eyes. From medial to lateral part of the eye (outwards). Damp warm cloth. New part of cloth each time. Wear gloves.
