Which of the following is a recommended nursing action when administering buprenorphine?

Providing sublingual administration is recommended when administering buprenorphine because this method allows for effective absorption of the medication into the bloodstream. Buprenorphine is often used in the treatment of opioid use disorder and chronic pain management, and when given sublingually, it bypasses first-pass metabolism in the liver, enhancing its efficacy. This route is not only convenient for patients but also helps in managing withdrawal symptoms and cravings when transitioning away from other opioids.

Other methods, such as intravenous administration, are not typically indicated for buprenorphine due to the formulation of the drug and its intended use. Additionally, dispensing by non-prescribers may violate legal regulations surrounding controlled substances, and using buprenorphine only in severe emergencies does not align with its intended use in chronic management scenarios. Thus, sublingual administration is the most appropriate and effective approach for this medication.
