When administering IV medications, the LVN should always:

Rationale:
A. Allow clients to adjust the pump for comfort is incorrect because clients should not adjust IV infusion pumps. Doing so can lead to over- or under-infusion, incorrect dosing, and serious harm. Only trained healthcare personnel should program and adjust infusion pumps.

B. Skip site assessments if the client is asymptomatic is incorrect because IV site assessments are essential even when the client has no symptoms. Early detection of infiltration, phlebitis, or infection can prevent complications. Skipping assessments increases risk of tissue injury and systemic infection.

C. Administer medications only during low census is incorrect because timing administration based on staff workload does not improve patient safety. IV medications must be administered according to the prescribed schedule and safety protocols, regardless of census.

D. Use infusion pumps for IV medications when indicated is correct because infusion pumps provide precise control over the rate and volume of IV medications, especially high-risk drugs like vasoactive agents, electrolytes, and pediatric medications. Pumps reduce the risk of dosing errors, rapid infusion, or fluid overload, making them a highly effective safety practice.

Rationale:

A. Use the largest vein possible is incorrect because vein selection should prioritize patient safety and comfort, not simply size. A smaller, accessible, and stable vein may be preferable, and using a large vein unnecessarily may increase risk of mechanical complications or infiltration.

B. Administer as rapidly as tolerated is incorrect because rapid administration of IV medications can cause adverse reactions, cardiovascular instability, or local irritation. IV medications should always be administered at the recommended rate specified in the provider’s order or medication guidelines.

C. Confirm medication compatibility with IV fluids is correct. The LVN must always check for chemical compatibility between the IV medication and any fluids running through the line. Incompatible medications can precipitate, reduce efficacy, or cause dangerous reactions, which may lead to emboli, phlebitis, or other complications. This step ensures safe and effective IV therapy.

D. Avoid flushing between medications is incorrect because flushing between medications is essential to prevent chemical incompatibilities and ensure that each medication reaches the bloodstream fully and safely. Skipping this step increases the risk of precipitation and adverse reactions.
