Rationale: Administering an additional dose of naloxone should be the first action taken by the nurse in this scenario. Naloxone is an opioid antagonist used to reverse the effects of opioid overdose. If the client's level of consciousness deteriorates after the initial dose, administering another dose can help further reverse the overdose effects and improve the client's condition. Once the additional naloxone dose is given, the nurse can then proceed to assess the client's response and consider other interventions as needed.

Rationale: When a client is prescribed risperidone, it is essential to monitor for potential side effects. Weight gain is a common side effect of risperidone, so the nurse should closely monitor the client's weight throughout the treatment. This monitoring helps in early detection of weight changes and allows for timely interventions to prevent further complications.

Correct Answer: C

Rationale: The correct answer is C. Clients prescribed fluoxetine should not stop taking the medication once they feel better without consulting their healthcare provider. It is essential to complete the full course of treatment as directed by the healthcare provider to prevent relapse or potential worsening of symptoms. Abruptly stopping fluoxetine can lead to withdrawal symptoms and may not effectively manage the condition. Therefore, it is crucial for clients to follow the healthcare provider's guidance regarding the duration of treatment with fluoxetine.
