Which IV access site is MOST appropriate for a patient who needs a long-term continuous infusion of a vesicant chemotherapy agent?
Answer: Central venous catheter (CVC)
Vesicant drugs must be infused via a central venous catheter to reduce the risk of severe tissue damage from extravasation.
A patient receiving IV fluids develops crackles in the lungs, jugular vein distention, and sudden weight gain. What complication is occurring?
Answer: Circulatory overload
Crackles, JVD, and rapid weight gain are classic signs of circulatory (fluid) overload from excessive IV fluid infusion.
The nurse is preparing to change IV tubing. How often should standard primary IV administration sets be routinely changed per CDC guidelines?
Answer: Every 96 hours
CDC guidelines recommend changing primary and secondary administration sets no more frequently than every 96 hours (4 days) unless clinically indicated.
A patient with a peripheral IV complains of pain, and the nurse notices the infusion is not flowing well. The area is cool and pale with swelling. Which condition is present?
Answer: Infiltration
Infiltration occurs when IV fluid leaks into surrounding tissue, causing coolness, pallor, swelling, and impaired flow.
Which laboratory value should the LPN monitor most closely in a patient receiving a rapid infusion of 0.9% NaCl?
Answer: Serum sodium
Rapid infusion of normal saline can elevate serum sodium, requiring close monitoring to detect hypernatremia.
The LPN notes that a patient's PICC line dressing is moist and the site appears red. What is the priority action?
Answer: Remove and replace the dressing using sterile technique
A compromised PICC dressing must be removed and replaced using sterile technique immediately to prevent central line-associated bloodstream infection (CLABSI).
Which action is MOST important before administering any IV medication through a peripheral IV site?
Answer: Check the IV site for patency and signs of infiltration
Verifying IV site patency ensures medication delivers properly and prevents extravasation or infiltration injury.
