In which situation is administering sedatives contraindicated?

Administering sedatives before obtaining informed consent is contraindicated because informed consent requires that the patient fully understands the procedure, its risks, and benefits, and is in a clear state of mind to make an informed decision. Sedatives can significantly impair cognitive function, judgment, and awareness, potentially leading to a lack of comprehension regarding the procedure. It is essential for patients to be alert and capable of engaging in the decision-making process to ensure that they can provide voluntary and informed consent.

In contrast, monitoring vital signs, conducting physical assessments, and providing patient education may involve sedatives when medically indicated, as they do not typically compromise the patient's ability to understand or make informed decisions about their care.
