Zorluk: OrtaReduction of Risk Potential

A practical nurse (PN) is reviewing the electronic health record of a client receiving a continuous intravenous heparin infusion for a pulmonary embolism. Which finding poses the greatest physiological risk to the client and requires immediate notification to the registered nurse?

  1. A platelet count of 85,000/mm³ that has decreased from a baseline of 210,000/mm³.Cevap
  2. B
    An activated partial thromboplastin time (aPTT) of 68 seconds.
  3. C
    A resting blood pressure of 106/64 mmHg and a heart rate of 88 beats per minute.
  4. D
    A missing barcode on the client's identification wristband required for medication scanning.

Cevap

The platelet count of 85,000/mm³ that has decreased from a baseline of 210,000/mm³.
A significant decrease in platelets (specifically a drop greater than 50% from baseline or a drop below 150,000/mm³) in a client receiving heparin strongly indicates Heparin-Induced Thrombocytopenia (HIT). This is a severe, immune-mediated complication that causes paradoxical widespread clotting and requires immediate notification of the registered nurse and healthcare provider to stop the infusion and initiate alternative anticoagulation.

Adım Adım Çözüm

1
Identify the client's current treatment and its associated severe risks.
The client is on a continuous heparin infusion, which carries a risk of severe bleeding and Heparin-Induced Thrombocytopenia (HIT).
Understanding the specific risks of high-alert medications guides the nurse to look for hallmark complications in the assessment data.
2
Analyze the laboratory data for critical values related to the therapy.
The platelet count has dropped by more than 50% and is critically low, whereas the aPTT of 68 seconds is perfectly therapeutic.
Differentiating between therapeutic effects and adverse reactions is essential for risk reduction.
3
Compare the severity of the physiological findings against environmental or administrative safety issues.
The platelet drop indicates a life-threatening physiological emergency, which takes strict priority over stable vital signs and missing barcode labels.
Clinical prioritization requires addressing immediate, life-threatening physiological complications before system or procedural issues.
