Difficulty: MediumReduction of Risk Potential

After receiving the morning handoff report, a practical nurse reviews the clinical data for four assigned clients. Which client situation presents the greatest risk for a severe complication and requires immediate communication with the registered nurse?

  1. A client taking warfarin for atrial fibrillation who has an International Normalized Ratio (INR) of 5.2Answer
  2. B
    A client who is requesting a prescribed oral analgesic 30 minutes before a scheduled physical therapy session
  3. C
    A client who is scheduled to receive routine morning medications but is currently missing an identification wristband
  4. D
    A client preparing for an elective procedure who needs the nurse to witness the informed consent signature

Answer

The client taking warfarin who has an International Normalized Ratio (INR) of 5.2.
An International Normalized Ratio (INR) of 5.2 is critically elevated beyond the standard therapeutic target of 2.0 to 3.0 for a client with atrial fibrillation. This places the client at imminent risk for spontaneous, severe hemorrhage. The practical nurse must immediately report this finding to the registered nurse so that anticoagulant medications can be withheld and the provider can determine if an antidote or dosage adjustment is necessary.

Step-by-Step Solution

1
Analyze each client situation to distinguish between routine nursing tasks, independent safety interventions, and critical physiological threats.
The analgesic request and consent signature are routine tasks. The missing ID band is a safety issue the nurse can fix independently. The INR of 5.2 is a critical laboratory abnormality.
Prioritization requires identifying which situation poses the most immediate risk of harm that exceeds the practical nurse's independent scope of practice.
2
Evaluate the clinical significance of an International Normalized Ratio (INR) of 5.2.
An INR of 5.2 is dangerously high and greatly exceeds the standard therapeutic range of 2.0 to 3.0 for a client with atrial fibrillation.
Elevated coagulation times indicate that the client's blood is clotting too slowly, creating a severe risk for internal or spontaneous bleeding.
3
Determine the appropriate nursing action for the critical finding.
The practical nurse must immediately communicate this critical laboratory value to the registered nurse.
The registered nurse must collaborate with the healthcare provider to potentially hold medications, administer antidotes, or order further diagnostic testing.
