What side effect should a nurse inform a client to expect after administering scopolamine (Transderm-Scop)?

Scopolamine is an anticholinergic medication commonly used to prevent nausea and motion sickness. One of the well-known side effects of anticholinergic drugs, including scopolamine, is dry mouth. This occurs because anticholinergics inhibit the action of acetylcholine, which in turn reduces the secretion of saliva and other bodily fluids.

Patients taking scopolamine may experience a sensation of dryness in the mouth, which can be uncomfortable. It is important for nurses to inform clients about this potential side effect, as it can lead to difficulties in swallowing or speaking and may require them to take measures to alleviate dry mouth, such as drinking water or using saliva substitutes.

The other options provided do not align with the common side effects of scopolamine. Diaphoresis, excessive urination, and pupillary constriction are not typical reactions associated with this medication. Understanding the correct side effects of medications can help patients manage their expectations and communicate effectively with their healthcare providers.
