Question: What is the target therapeutic International Normalized Ratio (INR)
range for a patient prescribed warfarin (Coumadin)?
✔✔ Answer: 2.0 to 3.0.
Question: What is the standard reference range for a D-Dimer assay to rule out
deep vein thrombosis or pulmonary embolism?
✔✔ Answer: 68 to 494 ng/mL.
Question: What is the reversal agent for warfarin toxicity, and what critical patient
teaching must accompany its use?
✔✔ Answer:
Antidote: Vitamin K.
Onset: It takes roughly 5 days to reach its full therapeutic effect.
Patient Education: Instruct the patient to maintain a steady, consistent daily
intake of vitamin K-rich foods (like green leafy vegetables) rather than
eliminating them or changing their diet abruptly, as sudden fluctuations will
destabilize their medication levels.
Question: What is the therapeutic target range for Partial Thromboplastin Time
(PTT) when a patient is undergoing active Heparin therapy?
✔✔ Answer: 46 to 70 seconds.
Question: What is the reversal agent for an unfractionated Heparin overdose or
toxicity?
✔✔ Answer: Protamine sulfate, which features a rapid onset of action to quickly
neutralize heparin's anticoagulant properties.
Question: What is the normal physiological reference range for a standard platelet
count?
, ✔✔ Answer: 150,000 to 400,000 cells/\muL.
Question: At what point does a low platelet count meet the clinical threshold for
thrombocytopenia?
✔✔ Answer: When the total platelet count drops to 50,000 cells/$\mu$L or lower,
significantly
