A nurse is admitting a client who has experienced a weight loss of 11 kg (25 lb) in the past 3 months. The client weighs 40 kg (88 lbs) and believes she is fat. Which of the following aspects of care should the nurse consider the first priority for this client?

A. "This medication may increase your blood pressure."

This statement is incorrect. Risperidone is not typically associated with significant increases in blood pressure. One of the potential side effects of risperidone is orthostatic hypotension, which is a drop in blood pressure when changing positions (e.g., standing up quickly). Therefore, this choice is not the best instruction to include in the teaching.

B. "Flu-like symptoms are an expected adverse effect of this medication."

This statement is incorrect. While risperidone can have side effects, flu-like symptoms are not commonly associated with it. Common side effects of risperidone may include dizziness, drowsiness, weight gain, and movement disorders. Flu-like symptoms are not a typical adverse effect of this medication.

C. "Avoid becoming overheated while taking this medication."

This statement is correct. Risperidone, like many other antipsychotic medications, can interfere with the body's ability to regulate temperature. This can lead to an increased risk of overheating, especially in hot weather or during vigorous physical activity. Therefore, it's important for patients taking risperidone to be cautious and avoid becoming overheated, as this could potentially lead to heat-related complications.

D. "Muscle twitches can occur the first few weeks while taking this medication."

This statement is incorrect. Muscle twitches are not a common side effect of risperidone. While it's true that some movement disorders can occur with antipsychotic medications, the statement is too specific to muscle twitches and does not accurately reflect the typical side effect profile of risperidone.

While preventing injury is important, it is not the highest priority when the client's respiratory and neurological functions are compromised. Managing the client's breathing takes precedence.

B. Applying a cooling blanket.

While hyperthermia (high fever) is a symptom of serotonin syndrome, the immediate concern is ensuring the client's breathing and neurological stability. Cooling measures can be beneficial, but they come after addressing the more critical issues.

C. Administering an anticonvulsant.

While anticonvulsants might be used to control seizures, preparing for artificial ventilation takes priority, as the client's airway and oxygenation must be secured before addressing other symptoms.

D. Preparing for artificial ventilation.

Explanation: Serotonin syndrome is a potentially life-threatening condition caused by an excess of serotonin in the body, often resulting from interactions between medications that affect serotonin levels. Severe manifestations of serotonin syndrome can include high fever, muscle rigidity, agitation, seizures, and even coma. In cases of severe serotonin syndrome, the client's neurological and respiratory functions can be compromised, making it crucial to ensure adequate ventilation and oxygenation.
