LPN IV Therapy and Fluid Management 3

Question 1

Which IV access site is MOST appropriate for a patient who needs a long-term continuous infusion of a vesicant chemotherapy agent?

Accepted Answer

Central venous catheter (CVC)

Answer

Vesicant drugs must be infused via a central venous catheter to reduce the risk of severe tissue damage from extravasation.

Question 2

A patient receiving IV fluids develops crackles in the lungs, jugular vein distention, and sudden weight gain. What complication is occurring?

Accepted Answer

Circulatory overload

Answer

Crackles, JVD, and rapid weight gain are classic signs of circulatory (fluid) overload from excessive IV fluid infusion.

Question 3

The nurse is preparing to change IV tubing. How often should standard primary IV administration sets be routinely changed per CDC guidelines?

Accepted Answer

Every 96 hours

Answer

CDC guidelines recommend changing primary and secondary administration sets no more frequently than every 96 hours (4 days) unless clinically indicated.

Question 4

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?

Accepted Answer

Infiltration

Answer

Infiltration occurs when IV fluid leaks into surrounding tissue, causing coolness, pallor, swelling, and impaired flow.

Question 5

Which laboratory value should the LPN monitor most closely in a patient receiving a rapid infusion of 0.9% NaCl?

Accepted Answer

Serum sodium

Answer

Rapid infusion of normal saline can elevate serum sodium, requiring close monitoring to detect hypernatremia.
