The nurse is preparing to administer 20 units of NPH insulin to a client. Before administering the medication, the nurse should implement which intervention?

This intervention is important to ensure accurate dosing and prevent medication errors. Insulin is a high-alert medication, meaning that it has a high potential for causing significant harm to the patient if administered incorrectly. Doublechecking the insulin dosage with a colleague can help prevent errors in dosing, which could lead to hypoglycemia or hyperglycemia in the client. It is also important to confirm the dosage since insulin dosing is based on individualized factors such as the client's blood glucose levels, weight, and overall health status.

Disulfiram is a medication used to treat alcohol use disorder (AUD). It works by inhibiting the enzyme acetaldehyde dehydrogenase, which is responsible for breaking down acetaldehyde, a toxic metabolite of alcohol. When alcohol is consumed while taking disulfiram, the accumulation of acetaldehyde in the body leads to unpleasant symptoms such as flushing, sweating, nausea, and vomiting. This creates an aversive reaction to alcohol consumption, which can help the client refrain from drinking.

The aversive effects of disulfiram can last for several hours to several days after alcohol consumption, depending on the dose of disulfiram and the amount of alcohol consumed. Therefore, it is important for clients taking disulfiram to avoid all sources of alcohol, including alcoholic beverages, mouthwash, and other products containing alcohol.

It is important to note that disulfiram is not a cure for AUD, and it works best when used as part of a comprehensive treatment plan that includes counseling and support. Disulfiram should only be used under the close supervision of a healthcare provider, as it can have serious side effects if used improperly.
