Question 1

Per current INS Standards of Practice, which solution is recommended as the first-line flush for most vascular access devices?

Accepted Answer

0.9% Normal Saline

Answer

The INS recommends 0.9% preservative-free Normal Saline as the first-line flush for most vascular access devices, reserving heparin for specific catheter types.

Question 2

A patient receiving vancomycin IV develops diffuse flushing of the face, neck, and upper torso with pruritus during the infusion. This reaction is best described as:

Accepted Answer

Red Man Syndrome

Answer

Red Man Syndrome is a rate-related infusion reaction to vancomycin caused by non-immunologic mast cell degranulation, characterized by flushing of the upper body.

Question 3

Which drug administration technique involves injecting a medication directly into an IV access port over a short period (typically 1–5 minutes)?

Accepted Answer

IV bolus (IV push)

Answer

IV bolus (IV push) delivers a concentrated dose of medication directly into the IV port over 1–5 minutes, achieving rapid peak plasma levels.

Question 4

Hyperosmolar solutions administered through a peripheral IV can cause which local vascular complication?

Accepted Answer

Chemical phlebitis and venous sclerosis

Answer

Hyperosmolar solutions draw water from vein endothelial cells, causing cellular dehydration, endothelial damage, chemical phlebitis, and ultimately venous sclerosis.

Question 5

When administering blood products through an IV line, which co-infusion solution is considered compatible and safe?

Accepted Answer

0.9% Normal Saline

Answer

Only 0.9% Normal Saline is compatible with blood products; D5W causes red blood cell hemolysis, and Lactated Ringer's contains calcium that can initiate clotting.
