The purpose of flushing an IV line before and after IV medication administration is to:

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. Rash, itching, or shortness of breath is correct because these are hallmark signs of an allergic or adverse reaction to IV medications. Symptoms may range from mild reactions like localized rash and pruritus to severe reactions such as anaphylaxis, which can include bronchospasm, hypotension, and respiratory distress. Immediate action is required, including stopping the infusion, notifying the provider, and administering emergency interventions if needed.

B. Client reports coolness at IV site is incorrect because coolness indicates infiltration, where IV fluid leaks into the surrounding tissue. Other signs of infiltration include pallor, swelling, and discomfort at the site. This is a local complication of IV therapy, not a systemic adverse medication reaction. It requires removal of the catheter and monitoring of the site, but it does not indicate an allergic reaction.

C. Blood return in the catheter is incorrect because blood return (also called flashback) indicates that the catheter is correctly placed in the vein. This is a normal finding, not a complication or reaction. It demonstrates patency and proper placement for infusion, and therefore does not signify an adverse effect of the medication.

D. Mild discomfort at insertion is incorrect because minor pain or discomfort during IV insertion is expected due to needle penetration of the skin and vein. This is normal procedural discomfort, not an adverse reaction. Nurses should still monitor for signs of phlebitis, infiltration, or infection, but mild insertion pain alone does not indicate a systemic medication reaction.
