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. 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.

Fluid excess, also known as fluid overload or hypervolemia, occurs when there is an excessive volume of fluid in the body. The nurse should assess for signs and symptoms of fluid excess, which include the following:

A. Bounding pulse: A bounding pulse, or a pulse that feels unusually strong and forceful, can be a sign of fluid excess. Increased blood volume leads to increased cardiac output, which can manifest as a bounding pulse.

B. Urine-specific gravity greater than 1.030: Urine-specific gravity greater than 1.030 typically indicates concentrated urine and is more indicative of dehydration rather than fluid excess.

C. Pitting edema: Pitting edema occurs when pressure is applied to the skin, resulting in an indentation or "pit" that persists after the pressure is released. It is a classic sign of fluid excess, indicating fluid accumulation in the interstitial spaces.

D. Swelling at the IV site: Swelling at the IV site may indicate infiltration or phlebitis rather than fluid excess. While fluid excess can lead to generalized swelling, swelling specifically at the IV site may suggest a local issue related to the IV infusion.

E. Crackles upon auscultation: Crackles, also known as rales, are abnormal lung sounds heard upon auscultation and are indicative of fluid accumulation in the lungs, which can occur with fluid excess. Crackles are typically heard in the bases of the lungs and may indicate pulmonary edema.
