PharmacologyCâu 77 / 100
A patient takes warfarin daily. Which instruction is most appropriate for the medical assistant to reinforce?
a.Double the dose if a headache develops
b.Keep scheduled blood tests such as INR, report unusual bruising or bleeding, and keep vitamin K intake consistent
c.Stop taking it whenever a cut or scrape occurs
d.Take an extra dose before dental work to prevent clots
Giải thích
Warfarin requires regular INR monitoring, prompt reporting of unusual bruising or bleeding, and a steady dietary intake of vitamin K, since swings in green leafy vegetables alter the drug's effect. Doubling or adding doses raises bleeding risk sharply. Starting or stopping an anticoagulant is a provider decision, not something a patient should do independently.
