Which filter size is recommended when administering 3-in-1 total nutrient admixtures (TNA) that contain lipid emulsions?
Answer: 1.2 micron filter
A 1.2-micron filter is required for lipid-containing admixtures because a 0.2-micron filter would trap fat particles and prevent proper infusion.
Why is Lactated Ringer's solution contraindicated for co-administration with blood products?
Answer: Its calcium content can promote clot formation in the tubing
Lactated Ringer's contains 3 mEq/L of calcium, which can bind to the citrate anticoagulant in blood products and promote clot formation in the IV tubing.
What is the maximum recommended peripheral infusion rate for potassium chloride (KCl) to prevent cardiac toxicity?
Answer: 10 mEq/hr
The maximum safe peripheral infusion rate for KCl is 10 mEq/hr; rates above this via peripheral access risk serious cardiac dysrhythmias and vein damage.
Which IV solution is contraindicated in patients with increased intracranial pressure (ICP) because it can worsen cerebral edema?
Answer: D5W
D5W is effectively a hypotonic solution once dextrose is metabolized, and free water can cross the blood-brain barrier and increase cerebral edema.
What is the primary purpose of using a 0.2-micron filter when infusing TPN without lipids (2-in-1 formulation)?
Answer: To remove bacteria, fungi, and particulate matter
A 0.2-micron filter removes bacteria, fungi, and particulate contaminants from non-lipid TPN, reducing the risk of catheter-related bloodstream infections.
Per INS standards, how frequently should IV administration sets used for lipid-containing solutions be changed?
Answer: Every 24 hours
Administration sets used for lipid-containing solutions must be changed every 24 hours due to the increased risk of microbial growth in lipid emulsions.
A patient receiving IV vancomycin develops sudden flushing, erythema of the face and upper torso, and pruritus. What is the most likely cause?
Answer: Red Man Syndrome from too-rapid infusion
Red Man Syndrome is a non-immune-mediated reaction caused by rapid vancomycin infusion that triggers mast cell degranulation, causing the characteristic flushing and erythema.
