Which procedure should NOT be performed according to standard patient care guidelines?

The procedure that should not be performed according to standard patient care guidelines is giving an enema. Enemas can have various indications, but their use is often reserved for specific medical conditions under professional supervision. For patients without clear medical need, or particularly for those in long-term care settings, administering enemas can pose risks, including potential for discomfort, dehydration, or damage to the rectal mucosa.

In contrast, the other options, such as giving insulin, administering tube feeds, and cutting nails, are common practices essential for managing patients’ health, and they generally fall within the scope of care that trained professionals can perform safely when appropriate protocols are followed.
