A charge nurse is teaching a group of nurses about the antagonist action of medications. The nurse should include in the teaching that which of the following antagonist medications is used for benzodiazepines?

A. Brain natriuretic peptide - Brain natriuretic peptide (BNP) is primarily used to diagnose heart failure and assess its severity. It is not routinely monitored in clients taking lithium.

B. Erythrocyte sedimentation rate - Erythrocyte sedimentation rate (ESR) is a nonspecific marker of inflammation and is not specifically related to lithium therapy monitoring.

C. Thyroid hormone assay - Monitoring thyroid function is essential in clients taking lithium because lithium can affect thyroid function, leading to hypothyroidism or hyperthyroidism. Therefore, checking thyroid hormone levels (T3, T4, and TSH) is important before administering lithium.

D. Liver function tests - While lithium can affect liver function in some cases, routine monitoring of liver function tests is not typically required for clients taking lithium. However, periodic liver function tests may be ordered if clinically indicated or if the client has underlying liver disease.

A. "You will need to take this medication on an empty stomach."

Lithium is typically taken with food to minimize gastrointestinal side effects. Instructing the client to take it on an empty stomach would be incorrect.

B. "You will need to stop this medication if you experience diarrhea."

Diarrhea is not typically a reason to stop lithium therapy. However, persistent diarrhea can lead to dehydration and electrolyte imbalances, which may affect lithium levels. It's essential for the client to report persistent diarrhea to their healthcare provider for further evaluation and management.

C. "You will need to consume a low-salt diet while on this medication."

A low-salt diet is not typically recommended with lithium therapy. In fact, lithium can cause sodium depletion, so it's important for clients to maintain adequate salt intake unless otherwise instructed by their healthcare provider.

D. "You will need your blood levels drawn weekly during the first month."

This statement is correct. Monitoring serum lithium levels is crucial to ensure the medication's effectiveness and prevent toxicity. Initially, frequent monitoring is necessary to establish the appropriate dosage and assess for any signs of toxicity. Weekly blood level checks during the first month of therapy are common practice.
