A patient is ready to receive PRBC in a medical unit. The assigned nurse knows that blood products should be started initially at which flow rate to prevent transfusion reaction?

Appeared in: AIIMS Delhi NO - 2017

Explanation

Starting a blood transfusion slowly is a critical safety protocol to detect early signs of an acute transfusion reaction.
The standard of care is to infuse at a slow rate, approximately 15 drops/min (about 1-2 mL/min), for the first 15 minutes.
This slow rate ensures only a small volume of blood is administered while the nurse closely monitors the patient for adverse effects like fever, chills, rash, or back pain.
If the patient remains stable after this 15-minute observation period, the flow rate can be safely increased to complete the transfusion within the recommended 4-hour window.

Option B: Starting at 30 drops/min is too fast for the initial observation period. It increases the volume of blood infused before a potential reaction can be identified, which could lead to a more severe outcome.
Option C: A rate of 60 drops/min is dangerously fast for initiating a blood transfusion. It significantly increases the risk of a severe, rapid-onset reaction and does not allow for adequate observation time.
Option D: This is false. Blood transfusion is a highly regulated procedure with strict, evidence-based guidelines established by organizations and healthcare facilities to ensure patient safety.

Clinical Relevance

Nursing practice connection: Use the key finding related to Safe administration of blood products (PRBC transfusion) to guide bedside assessment, documentation, and the next nursing action.
The first 15 minutes of a blood transfusion are the most critical for detecting acute hemolytic, allergic, or febrile reactions. The nurse's physical presence and vigilant monitoring are paramount for patient safety.
What if? The patient develops chills, fever, and lower back pain 10 minutes into the transfusion. The nurse must immediately stop the transfusion, disconnect the blood tubing, and start a new IV infusion with normal saline to keep the vein open. The physician and blood bank must be notified immediately, and the patient's vital signs monitored closely.

How to Approach the Question

This is a clinical procedure question testing knowledge of safety protocols.
First, identify the core task: safely initiating a PRBC transfusion.
Recall the cardinal rule of transfusion safety: 'Start low and go slow.' The initial phase is for observation, not rapid administration.
Evaluate the options based on this safety principle. The slowest, most cautious rate for the initial period is the correct choice.
Option A (15 drops/min for 15 min) represents a slow, cautious start, which is the standard of care.
Options B and C represent progressively faster rates, which are unsafe for the initial period.
