Which organization publishes the Infusion Therapy Standards of Practice that serve as the primary reference for CRNI exam content?
Answer: B. Infusion Nurses Society (INS)
The Infusion Nurses Society (INS) publishes the Infusion Therapy Standards of Practice, which is the primary reference standard for infusion nursing.
A patient receiving a unit of packed red blood cells (PRBCs) begins to complain of flank pain, chills, and shortness of breath 20 minutes after the transfusion was initiated. The CRNI notes the patient's temperature has risen to 101.5°F (38.6°C). What is the CRNI's PRIORITY action?
Answer: B. Stop the transfusion immediately and disconnect the tubing.
The patient is exhibiting classic signs of an acute hemolytic transfusion reaction (AHTR), a life-threatening emergency. The absolute first priority is to stop the infusion of the incompatible blood to prevent further hemolysis and end-organ damage. After stopping the transfusion, the nurse should maintain IV access with normal saline, notify the provider and blood bank, and monitor the patient closely.
A CRNI is caring for a patient receiving a continuous infusion of 3% Sodium Chloride for severe, symptomatic hyponatremia. Which assessment finding requires immediate intervention by the nurse?
Answer: D. New onset of confusion and signs of fluid overload.
Rapid correction of chronic hyponatremia with hypertonic saline can lead to osmotic demyelination syndrome (ODS), a severe neurological complication. The development of new neurological symptoms like confusion, coupled with signs of fluid overload (e.g., crackles in the lungs, edema), indicates that the correction may be too rapid or the patient is experiencing fluid volume excess. This is a critical situation requiring immediate cessation or slowing of the infusion and notification of the provider. A gradual increase in sodium within safe limits is the therapeutic goal. A mild headache and adequate urine output are less immediately concerning.
A CRNI is preparing to administer a 3-in-1 total nutrient admixture (TNA) containing dextrose, amino acids, and a lipid emulsion. Which in-line filter is required for the safe administration of this solution?
Answer: D. A 1.2-micron filter
A 1.2-micron filter is required for administering total nutrient admixtures (TNAs) or any lipid-containing parenteral nutrition. The lipid particles are too large to pass through a smaller 0.22-micron filter, which would cause an occlusion. The 1.2-micron filter allows the large lipid molecules to pass through while still filtering out particulate matter, larger microorganisms like Candida albicans, and precipitates.
