A client is admitted to a medical unit with a diagnosis of gastritis and chronic heavy alcohol abuse. Which medication should the nurse administer to prevent the development of Wernicke's syndrome?

A. placing all client belongings out of reach (A) does not promote safety as it may lead the client to attempt to get up unassisted to retrieve their items, increasing the risk of falls.
B. Instructing the client to call before getting up ensures that assistance is provided, preventing falls due to potential weakness or balance issues.
C. Initiating the use of a bed alarm helps in monitoring the client's movements, which is crucial in preventing falls, especially when the client might have impaired mobility.
D. Completing a swallow study before giving anything by mouth is essential to assess the risk of aspiration, which can be heightened due to possible swallowing difficulties post- stroke.
E. Placing the client in a room near the elevator does not directly promote safety; it could be beneficial for logistical reasons but does not address the client's immediate safety needs.
F. Providing a call button within reach allows the client to alert staff promptly if they need assistance, thus reducing the risk of injury.

A. This intervention is likely to be ordered due to the patient's fever and elevated heart rate, which may suggest dehydration or the need for increased fluid intake to support hemodynamic stability and mitigate the effects of fever and potential dehydration from fever and nausea.
B. Given the diagnosis of Pneumocystis pneumonia, the patient will likely be on or start antibiotics specific to this infection, such as trimethoprim-sulfamethoxazole. Monitoring for adverse reactions is crucial, especially in a newly diagnosed HIV-positive patient who might be starting multiple new medications.
C. While it is important to monitor CD4 counts in HIV-positive patients to guide treatment decisions, repeating the CD4 count immediately might not be prioritized unless there are specific clinical changes that suggest a rapid decline in immune function. Given the recent test results showing a CD4 count of 443 cells/mm^3, immediate retesting might not be clinically justified unless guided by other symptoms or considerations not detailed here.
D. Pneumocystis pneumonia does not require airborne isolation as it is not typically contagious between people under normal circumstances. Instead, it arises as an opportunistic infection in individuals with weakened immune systems. Hence, this order would not be appropriate unless there were other infections suspected that require such precautions.
E. The patient reports severe nausea, which not only is distressing but can also prevent the patient from taking oral medications and maintain necessary nutrition. Administering an antiemetic can help manage this symptom effectively.
