Which of the following is an important step when preparing to administer medications?

Checking for any medication allergies is a crucial step when preparing to administer medications because it helps prevent potential adverse reactions that could occur if a resident has an allergy to the medication being given. This safety measure ensures that the healthcare provider remains aware of the patient's medical history and previous drug sensitivities, which is vital for safe medication administration.

Understanding a patient's allergies allows the caregiver to make informed decisions and take necessary precautions before giving any medications. This contributes to patient safety and positive health outcomes, making it a foundational practice in the medication administration process.

While ensuring the resident is comfortable with the medication and confirming with another aide about the medication are also valuable practices, they do not directly address safety concerns that could arise from allergic reactions. Taking a break before administration might be beneficial for the caregiver's focus, but it does not relate directly to the critical preparation step of assessing the resident's allergies.
