Which statement is true regarding unfractionated heparin?

• A. It does not require monitoring
• B. It has a long elimination half-life
• C. It requires frequent monitoring of serum bleeding times
• D. It is only used in outpatient settings

Answer: (C)

Unfractionated heparin is an anticoagulant that is often used in acute settings due to its rapid onset and the ability to be quickly reversed if necessary. Monitoring is crucial when administering unfractionated heparin to ensure therapeutic effectiveness and to prevent adverse effects, particularly bleeding. This monitoring is typically done through the measurement of activated partial thromboplastin time (aPTT), rather than serum bleeding times. Regular testing is required to adjust the dosage accordingly, as individual responses to heparin can vary significantly. The need for frequent monitoring distinguishes unfractionated heparin from other anticoagulants that may not require such close supervision. Overall, continuous monitoring is a vital aspect of using unfractionated heparin safely and effectively during treatment.
