Registered Practical Nurse (RPN) Practice Test

Why are nursing interventions promoting hydration particularly important for psychiatric patients?

1. To simply prevent dehydration

2. To aid in medication absorption only

3. Because psychiatric medications can affect fluid and electrolyte balance

4. Because they generally refuse to drink water

The correct answer is: Because psychiatric medications can affect fluid and electrolyte balance

Nursing interventions promoting hydration for psychiatric patients are particularly important because psychiatric medications can significantly impact fluid and electrolyte balance. Many of these medications, including antipsychotics and mood stabilizers, can have side effects that may lead to conditions like dehydration or imbalances in electrolytes, which are vital for the body’s overall functioning. When patients are on psychiatric medications, their physiological responses may change, leading to an increased risk of dehydration, especially if they are experiencing side effects such as dry mouth, altered thirst perception, or increased metabolic demand. Ensuring adequate hydration is crucial not only for the effectiveness of the medications but also for the overall well-being of the patient, helping to prevent complications related to dehydration or electrolyte disturbances. While preventing dehydration is a component of promoting hydration, the need to manage the specific effects of psychiatric medications on fluid balance makes it a more critical intervention. The other options do not encompass the full range of reasons why hydration is essential for psychiatric patients, particularly the specific impacts of their medications on fluid and electrolyte regulation.
