What is a key principle of IV medication administration?

Double-checking medication orders and dosages is a critical principle of IV medication administration because it helps prevent medication errors that could result in serious harm to the patient. This practice ensures that the right medication, at the correct dose, is being given to the right patient, at the right time—often referred to as the "five rights" of medication administration. The complexity of IV medications, including their potency and the potential for adverse reactions, makes it imperative that healthcare professionals meticulously verify each medication and its dosage before administration. This step is essential to ensure patient safety and to uphold the standards of care in medical practice.

The other options, while presenting various aspects of medication administration, do not encompass the critical nature of thorough verification. Checking a medication only once puts patients at risk of receiving the wrong dosage or medication due to human error or oversight. Using any available syringe can lead to contamination or inaccurate dosing if the syringe is not appropriate for the medication being administered. Furthermore, administering medications quickly does not consider the patient's individual tolerance and could result in adverse effects; careful administration is vital to monitor and alleviate any discomfort or possible reactions.
