What would be an inappropriate practice when administering medication?

Ignoring patient allergies is an inappropriate practice when administering medication because it poses a significant risk to patient safety. Allergies can lead to severe reactions, including anaphylaxis, which can be life-threatening. Prioritizing knowledge of a patient's allergies is critical to preventing adverse effects and ensuring that medications administered do not trigger any harmful reactions.

In contrast, confirming the drug purpose, maintaining accurate dosage calculations, and following prescribed guidelines are all essential components of safe medication administration. These practices help ensure that medications are given correctly, at appropriate doses, and for the intended purposes, thus promoting optimal patient outcomes and minimizing risks.
