A nurse is caring for an adolescent client who is receiving carbamazepine for partial seizure disorder. Which of the following statements by the client's parent is the nurse's priority?

A. Prepare for gastric lavage due to an extremely elevated lithium level.

This option is incorrect. A lithium level of 1.0 mEq/L is within the therapeutic range for treating bipolar disorder or other mood disorders. Gastric lavage (stomach pumping) is not indicated for this level of lithium concentration.

B. Check the client's medication record to assess whether the client has been refusing her lithium.

This option is not directly relevant to the client's current lithium level of 1.0 mEq/L. While it's important to monitor medication adherence, the client's lithium level is within the therapeutic range, so there is no immediate concern about refusal or non-adherence.

C. Administer the morning dose of lithium.

This option is correct. With a lithium level of 1.0 mEq/L, which falls within the therapeutic range for treating bipolar disorder, the nurse should proceed with administering the morning dose of lithium as prescribed. It's important to maintain therapeutic lithium levels to effectively manage the client's condition.

D. Hold the medication and assess for early manifestations of toxicity.

This option is incorrect. With a lithium level of 1.0 mEq/L, there is no indication to hold the medication or suspect early manifestations of toxicity. Monitoring for lithium toxicity is important, but it's not warranted in this scenario where the lithium level is within the therapeutic range.

A. Rotating the staff who administer medications is generally counterproductive for a client with bipolar disorder or suspected non-adherence. Consistency in the nursing staff helps build a therapeutic alliance and trust, which are foundational for successful medication management. Frequent changes in personnel can lead to confusion, increased suspicion, and a lack of accountability in the nurse-client relationship.

B. Engaging the client in conversation immediately following the administration of medication is a subtle but effective clinical intervention. This strategy ensures the client has swallowed the medication by requiring vocalization, which prevents the client from "cheeking" or hiding the dose in the buccal cavity. It provides a non-confrontational method to verify ingestion while maintaining a positive and social therapeutic environment.

C. The use of sustained-release forms or long-acting injectable antipsychotics significantly improves adherence by reducing the frequency of administration. These formulations maintain a stable therapeutic serum concentration over a longer period, which is especially beneficial for clients who struggle with daily regimens. Reducing the burden of medication management minimizes the risk of relapse associated with missed doses.

D. Providing for once-daily dosing is a scientifically proven strategy to enhance medication compliance by simplifying the treatment schedule. Complexity in drug regimens is a primary barrier to adherence, particularly in psychiatric populations where cognitive symptoms may be present. A single daily dose is easier for the client to incorporate into a routine, thereby increasing the likelihood of long-term therapy maintenance.

E. Performing mouth checks following the administration of medication is a direct nursing intervention used to confirm that the client has truly swallowed the dose. This process involves a respectful but thorough inspection of the oral cavity, including under the tongue and along the gum lines. It is a standard safety protocol in mental health settings to ensure the delivery of prescribed psychiatric treatment.
