INTRODUCTION
You are a surgeon and today you will operate on John Manfrenjensen, a 10 year old boy who was injured in
an earthquake. In order to prevent a dangerous blood clot after surgery you need to prescribe a blood
thinner called Warfarin TM which can cause severe bleeding resulting in death if too much is given. The
patient weighs 88 lbs. The pediatric dose for Warfarin as recommended by the manufacturer is 0.2mg/kg to
be taken by mouth twice daily for two days following surgery. (Read that as 0.2 kg of the medicine per each
kg of body weight)
PROMPT
Write a prescription for your patient indicating exactly how many 1mg Warfarin TM tablets to take at a time.
When you sign the bottom (you are the Medical Doctor "MD") you are accepting legal responsibility and can
be sued for malpractice if you prescribe the wrong dose and cause harm.
Tip: Convert pounds to kilograms first. The conversion factor is 1 kg = 2.2 lbs. Then multiply the boy's weight
in kg by the pediatric dose given in the introduction.

Answer 1

When pain or disability occurs after rotator cuff surgery, post-operative imaging is frequently performed. Post-operative complications and expected post-operative imaging findings in the shoulder are presented, with a focus on MRI, MR arthrography (MRA) and CT arthrography. MR and CT techniques are available to reduce image degradation secondary to surgical distortions of native anatomy and implant-related artefacts and to define complications after rotator cuff surgery.
