Which finding during IV medication administration requires the most immediate intervention?

Rationale:

A. Client's meal preference is incorrect because meal preferences do not impact IV therapy safety. While nutrition and hydration are important aspects of overall care, they do not affect the IV infusion, medication absorption, or the risk of IV-related complications. Focusing on meal preference during medication administration could distract from critical safety assessments.

B. Room temperature is incorrect because, although room comfort can affect patient satisfaction, it does not directly influence the safety or effectiveness of IV therapy. Environmental temperature is not a factor in detecting or preventing complications such as infiltration, phlebitis, or systemic medication reactions.

C. IV site and client response is correct because these are direct indicators of the patient’s immediate safety during IV therapy. IV site assessment includes checking for redness, warmth, or swelling which may indicate phlebitis; coolness, pallor, or taut skin which may indicate infiltration; pain, burning, or leakage which may indicate infiltration or extravasation, especially with vesicant medications; and purulent drainage which suggests infection at the catheter site. Client response assessment includes monitoring for vital signs changes such as hypotension, tachycardia, or hypertension which may indicate fluid overload, adverse reaction, or medication effect; allergic reactions such as rash, itching, dyspnea, or stridor which may indicate anaphylaxis; and pain or discomfort which may signal local complications or improper IV placement. Repeated assessment allows early recognition of both local and systemic complications, enabling immediate interventions such as stopping the infusion, notifying the provider, applying interventions like warm or cold compress, or adjusting the infusion rate.

D. Client's favorite beverage is incorrect because it is irrelevant to IV therapy and does not provide information about IV site integrity or patient safety.

Rationale:
A. Maintain IV access without continuous infusion is correct. A saline lock, also called an intermittent IV device, is a short catheter inserted into a peripheral vein and capped with a heparin or saline flush port. Its purpose is to keep the vein patent (open) for intermittent IV medication administration or emergency access, without requiring the patient to be attached to a continuous IV fluid line. Between uses, the line is flushed with saline to prevent clot formation and maintain patency. This is especially useful for patients who do not require continuous fluid replacement but may need rapid IV access for medications, fluids, or emergency interventions.

B. Provide continuous IV fluids is incorrect because a saline lock is specifically designed for intermittent use. Continuous IV therapy requires a standard IV line with a fluid bag and infusion pump, which delivers fluids at a constant rate. Using a saline lock in place of a continuous infusion would not maintain adequate fluid administration.

C. Increase medication absorption is incorrect because the saline lock does not affect how the medication is absorbed. It is simply a method for delivering IV medications directly into the bloodstream. Absorption occurs the same way whether administered through a saline lock or continuous IV.

D. Prevent phlebitis is incorrect because while proper flushing of a saline lock can reduce the risk of clot formation or catheter occlusion, it does not prevent phlebitis, which is inflammation of the vein due to mechanical irritation, chemical irritation from medications, or infection. Preventing phlebitis involves correct catheter insertion technique, appropriate catheter size, careful medication selection, and monitoring the insertion site.
