Cecil and his wife are traveling to Southeast Asia on vacation and he has come into the clinic to review his medications. He is healthy with only mild hypertension that is well controlled. He asks about getting 'a shot' to prevent blood clots like his friend Ralph did before international travel. The correct response would be:
- A. Administer one dose of low-molecular weight heparin 24 hours before travel
- B. Prescribe one dose of warfarin to be taken the day of travel
- C. Consult with a hematologist regarding a treatment plan for Cecil
- D. Explain that Cecil is not at high risk of a blood clot and provide education about how to prevent blood clots while traveling
Correct Answer: D
Rationale: Cecil's low risk doesn't warrant prophylaxis; education on hydration and movement suffices. Heparin or warfarin is overkill without indication.
