A school nurse is talking with a 13-year-old female at her annual health-screening visit. Which of the following comments made by the adolescent should be the nurse's priority to address?

Lithium is a commonly used medication for treating bipolar disorder, and therapeutic drug monitoring is crucial to ensure its effectiveness and prevent potential toxicity. Monitoring the client's lithium levels in the blood is important because lithium has a narrow therapeutic range, meaning that levels that are too low might not provide the desired therapeutic effect, while levels that are too high can lead to toxicity.

B) "This medication is addictive, so you will need to discontinue it in six months."

Lithium is not considered addictive. It's important to provide accurate information about the nature of the medication to avoid unnecessary concerns.

C) "Weight gain should be reported to your provider as an indication of lithium toxicity."

While weight gain can be a side effect of some medications, it's not a specific indicator of lithium toxicity. Lithium toxicity is characterized by a range of symptoms including tremors, confusion, nausea, vomiting, and excessive thirst, among others.

D) "Your provider may prescribe a diuretic if you have trouble urinating while taking lithium."

Diuretics are generally not recommended with lithium because they can increase the risk of lithium toxicity. Lithium can affect kidney function, and using diuretics may exacerbate this effect. The client should be advised not to use diuretics without consulting their healthcare provider.

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.
