When administering IV medications, the LVN should always:

Rationale: A. Administering IV medications as rapidly as tolerated is incorrect because many medications must be infused slowly to prevent adverse reactions such as hypotension, arrhythmias, or vein irritation. Rapid administration can be dangerous and is not a safe standard practice. B. Using the largest vein possible is not always appropriate. The choice of vein should consider the type of medication, the condition of the patient’s veins, and the risk of irritation or phlebitis. Selecting a vein solely based on size can increase the risk of complications. C. Confirming medication compatibility with IV fluids is the correct action because some medications can precipitate, inactivate, or interact negatively with certain IV solutions, leading to complications such as emboli, reduced efficacy, or vein irritation. Ensuring compatibility protects the patient from harmful reactions and ensures the medication is effective. D. Avoiding flushing between medications is incorrect because flushing the IV line with compatible fluid between medications helps prevent drug interactions within the line and ensures complete administration of each drug. Flushing is a critical safety step in IV therapy.
