Registered Practical Nurse (RPN) Practice Test

A key reason for promoting hydration in patients on psychiatric medications is to:

1. Enhance their appetite

2. Aid in their physical exercise routine

3. Prevent adverse effects from dehydration

4. Encourage them to avoid drinking during meals

The correct answer is: Prevent adverse effects from dehydration

Promoting hydration in patients on psychiatric medications is crucial primarily to prevent adverse effects from dehydration. Many psychiatric medications can lead to side effects that increase the risk of dehydration, such as dry mouth, increased sweating, or urinary retention. Dehydration can exacerbate these side effects, potentially leading to more serious complications like confusion, dizziness, and even delirium. Maintaining adequate hydration helps to mitigate these risks and supports overall health and well-being. Encouraging hydration is not primarily focused on enhancing appetite, aiding in physical exercise, or regulating drinking during meals. While hydration can have positive effects on overall health, the immediate concern with psychiatric medications is ensuring that patients do not suffer from the negative consequences associated with dehydration. This focus on prevention and management of side effects is critical in providing safe and effective care for patients undergoing psychiatric treatment.
